Q

Do we want to SI joint to be hypermobile or hypomobile?

A

We want the SI joint to be hypomobile because the SI Joint is designed to be a stabilizer

Want the joint to be properly aligned—we do not mobilize it to increase mobility

Q

When do we want the SI joint to have play?

A

labor and delivery

The pelvis have lateral movement to allow baby’s head and shoulders to come through: females designed to have increased mobility at the joint during labor and delivery

Problems occur postpartum:
PT treat postpartum women, important to look at when looking at back issues and women’s health issues. It has a different connection than any other joint.

Q

How is SI joint Locus for dissipating of energy in bipedal locomotion?

A

-Pelvis needs to rotate during gait: swing to HS, midstance neutral, opposite in push off
(pelvis rotate contralaterally in gait: one side in HS and the other side in pushoff)

  • SI joint is the connection between the LE and the spine
  • –>connection between the innominate bone (hemipelvis) has its articulation with the sacrum (the sacrum is the bottom part of the spine)

Q

How does Lower extremities amplify the movement of the SI Joint?

A

(Can visualize what is happening in pelvis by looking at movement of LE)
Heel strike through swing to push off:

Leg moves through swing the LE amplifies posterior rotation of innominate bone

To neutral

To push off: LE goes into extension as innominate rotates in anterior direction

Q

Is the SI under voluntary control?

A

SI is not under volitional control

even though muscles attach there is no activating force to move it –it happens as a secondary passive effect to movement in muscles ie from hip joint

SI Anatomy

A

Closed osteoarticular ring with three bony parts and three joints

o 3 Bones:

  • -2 innominate bones
  • -Sacrum

o 3 Joints:

  • -2 SI joints
  • -Pubic symphysis – between 2 pubic rami: Diarthroidial with symphysis in the front (SIJ)

Q

Pelvis: There is complete interdependence of all three joints

what happens if forces not balanced?

A

Balance of force from ground and force from top: there needs to be an interdependence between the three components of the osteoarticular ring

–ie inferior: LLD: imbalance of forces entering pelvis

–ie superior: scoliosis, lateral shift, hemivertebrae (triangulated shape of vertebra creates scoliosis)

Q

Pelvis: Function of the pelvis:

A

–Bony pelvis transmits forces from the vertebral column to the lower limb:
(Bony pelvis is center point for transmitting forces)

–There is a ground reaction transmitted to the acetabulum by the head and neck of the femur
(Force comes down from the trunk–trunk that is loaded down entire vertebral column—dissipated at the top of the 2 innominate bones
2 legs equally placed on the leg, force comes up both legs and dispersed around pelvis rim)

–There is complete interdependence of all three joints

Q

Sacrum

  1. shape
  2. cartilage
  3. concave/convex rule
A

has a corresponding articular facet to the part that is on the iliac/innominate bone

  1. Corresponds in shape with a furrow bordered by two crests: TWO crests and ONE furrow so they can interlock one top of the other—this prevents sliding of innominate on sacrum
  2. Lined with hyaline cartilage which is 2-3x thicker than the fibrocartilage cartilage on innominate bone

Does not truly follow the concave/convex rule
There is a depression on the sacrum that articulates with crest on innominate

Q

How an issue in pelvis can be created when imbalance of muscle:

Weakness–ie gluteus medius

Tightness –ie illiopsoas

A

• Weakness: If there is significant atrophy or weakness on one side there will be a change in alignment
ie gluteus medius will change gait, the pull, and balance.

• Tightness: if I have tight illiopsoas on one side, it will pull anteriorly on anterior innominate on one side and not other side. If innominate is pulled on right by illiopsoas or hamstring it will passively change the alignment.

Q

What influences the pelvis in standing position?

A

pelvis influenced by both structural and functional asymmetry of LE’s

**force comes up from LE
anatomical or functional LLD —>uneven as we have ground force coming up one side vs the other

Ambulate with LLD create pelvic obliquity which create a dysfunction in the pelvis: rotational or elevation component

**important to adjust LLD because pelvic obliquity causes lumbar spine side-bend rotation with scoliosis which works its way up thoracic to cervical spine—creates long term low back and pelvis issues

Q

What influences innominate in supine position?

A

Supine: stabilized by WB on table, innominate respond to tension from below

change in alignment of pelvis from tension in LE –ie if contracture and get asymmetrical alignment from tension

WB is on innominates on the table, get changes in alignment of pelvis from tension of the LE’s

Ex: hip flexion contracture on one side and lying on table and leg held up in Thomas test position will cause asymmetrical tension on the pelvis
We repeat some of the positions

Q

Upslip: crest heights

Will it be different in WB or in NWB?

A

Iliac crest will be high on the side of the superior displacement
In NWB because it is a dysfunction of the pelvis, it will appear to be uneven

Not in weight bearing because when you’re in WBing position, if your leg lengths are the same, and the leg is planted on the ground, the pelvis will level out and your spine will take up the slack (back accommodates for it)

Traumatically induced injury: rarely ever see these because mode of action is unusual and because when you stand on your feet, if one side is pushed down and walk run or pound on that leg – it self correct

If it is really jammed – then it has to be corrected but it is hard to do

Etiology: Example: Somebody thrown from horse and got caught in stirrup – pulls one leg down/Falling form tree – gets stuck in vine or tree and hung from one leg

See more with female patient because of laxity – depending on cycle or pregnant
Self corrects if you just have them hop in standing because of WBing forces

Q

Right on Right

A

rotate on an oblique: right rotation around a right oblique axis

Anterior rotation/torsion
*related to anterior surface of what would be the vertebral body: Forward rotation moving toward the anterior surface of vertebra

Considered to be a normal physiological movement (Happens in the process of the unilateral stance side)
**problem is when get stuck in the position whether it is a normal or abnormal movement.

R on R: deep L base and a posterior R ILA

107
Q

What type of pelvic movement in gait?

A
  1. heel strike, foot flat, toe off = pelvis rotates: as you do that, sacrum rotates on the oblique axis with every step (doesn’t do nutation counternutation which is symmetrical): this allows for asymmetrical movement
  2. Each HS get anterior torsion of sacrum
108
Q

what part of gait anterior torsion?

A

Happens in the process of the unilateral stance side

109
Q

Left on Left:

A

Rotate anteriorly around the left oblique axis: rotate towards the left

Left rotation around the left oblique axis which is referred to as an anterior torsion

and it is a normal physiological movement

110
Q

Right on Left

A

Right rotation around left oblique axis is a posterior torsion,

and it is a non physiological movement (posterior torsion)

111
Q

Sacral Extension

A

unilateral superior sacral shear

Sacrum slides up and back

SACRAL BASE moves POSTERIOR and SUPERIOR

and the ILA moves SUPERIOR:

112
Q

Sacral Flexion

115
Q

Gait Cycle

–Iliosacral Movement

A

each innominate rotates anteriorly and posteriorly during the walking cycle

**Start from mid stance in neutral, as swing leg the innominate bone moves posterior on side that we’re swinging, then rotate as get to midstance, and then anterior rotation until push off

116
Q

Gait Cycle

–Sacral Movement

A

The axis of rotation originates on the side of the weight bearing leg, rotation towards the WB leg

L on L, return to neutral, then R on R, then return to neutral

At midstance of gait cycle the axis of rotation of sacrum is on the side of the weight bearing leg and it is always an anterior torsion.

117
Q

Gait at midstance: sacrum/ilium

A

At midstance point, the axis of rotation and innominate bone goes from posterior to anterior rotation, innominate neutralizes in midstance because about to reverse, axis of rotation of sacrum is on side of WB leg (midstance leg) and sacrum will rotate anteriorly.

Right on right on midstance right leg.

118
Q

Innominate in Gait

  • Initial Swing
  • Midstance
  • HS
A

Initial swing – innominate rotates posterior

Midstance – neutral

push off– innominate rotates anterior

119
Q

When sacrum rotates, does sidebending occur?

A

* When sacrum rotates it also does contralateral side bending*

when the sacrum rotates to the right, simultaneously it does left side bending

120
Q

How does sacral/lumbar rotation/sidebending relate?

A

When sacrum rotates, the lumbar spine rotates to the opposite side/ when sacrum sidebends, lumbar spine sidebends to the opposite side

It allows us to be upright

Sacrum rotates to side of concavity in the lumbar spine

121
Q

Sacral Movement
–The axis of rotation originates on the side of the weight bearing leg
L on L return to neutral, then R on R, then return to neutral

122
Q

Baer’s Point

2 ideas

A

Anterior location that is above the SI joint

Dutton: 1/3 of the way down on the diagonal that goes between ASIS and the pubic symphysis (1/3 of the way down on the line, it is close to the front of the SI joint)**
=Gives more a superior part of the joint

Minel: 2 inches from umbilicus (more medially) between umbilicus to ASIS
=Gives you more inferior part of joint

123
Q

Iliopsoas Muscle

palpate

A

Proximal attachment to TP’s and vertebral bodies of T12-L1-L5

Palpate medial and deep to ASIS and at insertion on lesser trochanter

124
Q

PSIS

palpate

A

Locate iliac crests, come down on a 30-45 degree angle

Roll thumbs underneath

125
Q

Sacral base palpate

A

from PSIS drop in and now on sacral base

126
Q

What is sacral sulcus?

A

Sacral sulcus is relationship between sacral base and PSIS

127
Q

Palpate ILA

A
  1. Hiatus: finger goes in and find SP and dip in to get the hiatus
  2. If move lateral from hiatus to get ILA-can have finger posterior or inferior to ILA
128
Q

palpate piriformis

A

Go from ILA to trochanter to find piriformis, take finger in and trace piriformis and note is feel spasm

129
Q

Palpate sciatic nerve

A

Look at relationship PSIS and IT find the space to dip into for the sciatic nerve—can find path by the indentation you can get into—area of foramen as it starts to course down

130
Q

Palpate sacrotuberous ligament

A

Find IT, drop in medially, and feel the sacrotuberous ligament

131
Q

Piriformis muscle

A

Attaches from the anterior inferolateral aspect of the sacrum to greater trochanter

Trace along length to palpate

Piriformis is over the sciatic nerve (15% of population, sciatic nerve goes through but most of the time is goes under)

You will only feel it if it is in spasm

132
Q

Sacral sulcus

palpate

what it tells us

A

Space between sacral base and PSIS:

tells us about relationship between innominate and sacrum

133
Q

What happens to sacral sulcus if innominate rotated poseriorly?

A

If innominate is rotated posteriorly: PSIS and sacrum relationship increases and get a deeper sulcus

134
Q

What happens to sacral sulcus if innominate rotated anteriorly?

A

If innominate is rotated anteriorly, PSIS and sacrum relationship diminishes and get smaller sacral sulcus

135
Q

Palpate sacral hiateus

A

travel down sacrum and in area of S5 there is an indentation before the coccyx
S5 – feel an indentation

136
Q

palpate ILA

why palpate posterior and underneath?

A

Move laterally, 1-1/2 inch from sacral hiatus, you’re on ILA

rotation detect on posterior aspect of ILA

sidebending we put finger underneath ILA (feel for shear)

137
Q

quadratus lumborum

A

posterior iliac crest and iliolumbar ligament
–> 12th rib and TP of L1-L5

***Sensitivity at inferior aspect of last rib indicates spasm or muscle contraction

138
Q

Iliolumbar ligaments:

A

Indirectly palpate through the erecti spinae along the superior, medial aspect of the iliac crests

Sensitivity implies involvement

139
Q

Standing posture

scoliosis/kyphosis

A

in WB: can see functional scoliosis

upslip/downslip cannot create LLD in WB , so the accommodation that occurs for change in elevation of the pelvis will be a functional scoliosis because it pulls on the lumbar spine

140
Q

Sitting Posture and Ability to Sit

A

Asymmetrical sitting posture: patients with SI issues have a hard time sitting and don’t like sitting involved side, see them with their legs crossed

141
Q

Sit to stand

A

a posterior rotation to an anterior rotation as I go from sit to stand:

as my pelvis has to rotate to get up in movement from sit to stand, then one side is stuck and painful for patient to transition and therefore the transition of sit to stand will be a complaint of the patient in addition to sitting

142
Q

Gait

abnormalities in gait pattern?
(2)

when in gait get pain?

A
  1. decreased stride length on side of affected SI
  2. antalgic gait

PAIN:
pain on unilateral stance
(HS–>midstance)

pain if stuck b/c R on R and
L on L in gait

143
Q

Why watch facial expression for SI discomfort?

A

SI derangement is very uncomfortable

Different kind of pain than discogenic patient, the pain is very deep and painful with daily activities ie sit, sit to stand, walk

144
Q

Pseudo Sciatica

A

piriformis attach on inferior lateral sacrum,
sciatic nerve pass under/near piriformis
rotation that can occur in sacral and innominate dysfunction

SI dysfunction can create tension on area sciatic nerve passes through or under piriformis
=distal part of sciatic nerve under piriformis

**McKenzie WONT help

145
Q

LBP

where will the LBP be if it is SI?

A

intimate relationship between the lumbar spine and the SI creates LBP

the LBP will be centered further down (lumbar point to low back, SI point to SI deep inside or buttock pain)

146
Q

Pesudotrochanteric bursitis

A

distal piriformis attach at greater trochanter –need to tx SI

147
Q

    (ie Pubococcygeus)
  2. Can get pelvic floor dysfunction as well
151
Q

Classic history for SI dyssfunction

8

A
  1. Direct trauma to the area:
  2. Low back injury secondary to lifting with flexion and rotation
  3. Unexpected heelstrike
  4. Asymmetrical sitting/standing posture:
  5. Asymmetrical sleeping posture
  6. Pregnancy
  7. Childbirth
  8. Menstrual cycle
    (Menstruation and ovulation there is more laxity in pelvis)
152
Q

Pelvic girdle questionnaire

A

4 point scale
20 items

very typical

  • how you dress yourself
  • can you stand for less than 10 minutes
  • bend
  • sitting/parameters for sitting
  • things that are directly related to SI rather than using a generic back questionnaire
  • can use it as an outcome measure if you know they have pelvic issue

developed in Norway – more in tuned to this issue
good scale, high ICC

153
Q

SI

Typical Pain Patterns (3)

A
  1. Pain centered over the SI joint
    - -Use the one finger and tell me where it is, patients put their finger into the SI – not diffuse, can really pinpoint it for you
    - One finger test in literature =“Fortin finger test”
  2. Pseudo SI pattern
  3. Diffuse pain from buttock radiating to posterior LE
    - -Rarely see pain go below knee joint, usually just buttock and if it does radiate it goes down posterior aspect of thigh
154
Q

Structural Examination

INNOMINATE ON SACRUM
Innominate rotation round the sacrum and it is an IS problem:

  1. Eyes level to PSISs, fingers under the PSISs.
    DO NOT stabilize pelvis because we want it to move following the lumbar spine.

Patient stands with knees extended. Ask patient to roll down as though you are going to touch your toes

  1. Normal: both PSIS rise forward simultaneously and equally
  2. Positive finding: one side (PSIS) moves first and further: ultimately more superiorly/cranially displaced that side is positive = IS PROBLEM

Q

PRONE

LLD

why diff than supine?

A

SACRAL DYSFUNCTION

Prone: Pelvis supported by pubic symphysis and ASIS, sacrum responds to trunk

**prone LLD is a function of how the sacrum is located between the two innominate bones **

supine LLD as a function of innominate bone and as a function of anatomical leg length

they don’t have to be the same.

Q

SUPINE #1

LLD

true anatomical vs functional

how can we find combination of anatomical and functional leg length discrepancy on the same side?

A

IS DYSFUNCTION

POSTERIOR INNOMINATE: functional LLD: leg shorter
=It is a functional change to accommodate for a true anatomical change:

vs TRUE LLD:
Ie right leg is longer, then find a POSTERIOR INNOMINATE on that side to try to compensate for the longer anatomical leg to make it functionally shorter so it is not as long from one side to the other

197
Q

SUPINE #1

Long Sitting Test

  1. The test
  2. Normal
  3. Positive
A

IS DYSFUNCTION

this is only for functional LLD

  1. supine position, pt told to level pelvis: bend knees in hooklying lift pelvis and drop back down to table, allow to straighten out legs.

Compare LE lengths at medial malleoli

pt longsit from supine

  1. NORMAL: leg length equal in supine and remains equal in long sitting position
  2. POSITIVE: one leg that is either equal or shorter in supine: and then when patient goes into long sitting, the short leg becomes much longer (ie b/c posterior innominate)

{False negatives/positives: Weak abdominals, uneven hamstring length}

198
Q

Why the supine #2 Long Sitting Test Works?

A

If posterior innominate which creates a functionally short leg, the acetabulum will be cephalically displaced

Then as you go into long sit pelvis evens out and the relative position of acetabulum goes from superiorly displaced position to a more normal neutral position

(evens out because the whole thing rotates together )

199
Q

FABERE (Patrick) Test:

Rationale:

Test:

A

SI vs. Hip

RATIONALE: differentiate between hip joint and sacroiliac joint pain

TEST: Patient is put into a figure of four position, Place one hand on the pelvis and the other hand on the distal femur and create an opening

HIP = If figure of four hurts we suspect the hip

SI = if one hand on the pelvis with the other compressing on the knee makes the pain more intense we suspect the SI joint

200
Q

Prone Knee Bending (Nachlas)

Rationale:

Test:

A

RATIONALE: L3 NR

TEST: pt prone, flex knee so heel approach buttock

Pain anterior thigh = tight rectus femoris

POSITIVE:
1. reproduction of symptoms radiating anterior thigh/medial knee and/or backpain = correlated with L3 diagnosis

  1. If patient has very hypomobile SI on ipsilateral side or tight anterior structures, as you pull the knee to the flexed position the iliac rim will start to move because it doesn’t tolerate this and get ASIS rotating forward as it gets pulled
201
Q

Gaenslen’s Test

Test

Indications (4)

A

Test: Put patient toward the edge of table / Flex the leg that you’re not testing to 90 degrees, hold it there-have them hold it from posterior aspect of thigh / Then extend and abduct the contralateral side that is off the side of the table

indications
1. SI dysfunction

  1. Pubic symphysis instability (creating a hemipelvic rotation)
  2. Hip pathology (capsular pattern hip hyperextension is limited)
  3. L4 nerve root irritation
    (input into the femoral nerve and you’re hyperextending the anterior structures (can get some stretch on the front, can also reproduce some of the radicular complaints that the patient might have from L4 nerve root)
202
Q

Thigh Thrust (POSH test – posterior sheer test):

  1. Test
  2. Positive
  3. what it confirms
A
  1. Test:
    - ->pt supine, painful hip flexed 90 degrees
    - ->PT stand opposite side of table, one hand under sacrum (bridging effect),
    - ->Force: toward table in line of femur through the SI joint on that side
  2. POSITIVE: reproduction of symptoms [creating posterior shear of the innominate bone through the femur]
  3. confirms: side
203
Q

Squish Test

Test: 2 options
Positive:

A

Test:
patient supine,
Hands on ASIS and push posterior and medial force: apply downward and medial force (adduction and posterior)
Force: towards sacrum and back

*can do one side at a time: so that also a rotational force on the innominate bone on a side to side, to differentiate one side to the other: will probably feel a difference in movement if its positive on one side

POSITIVE: reproduction of pain
=determines side of dysfunction

206
Q

Flexibility Tests:

Hamstring SLR

A

With the patient’s knee extended, take the patient’s foot by the heel and ele- vate the entire leg 35–70 degrees from the examining table. As the leg is raised beyond approximately 70 degrees, the sciatic nerve is being completely stretched and causes stress on the lumbar spine. The patient will complain of increased lower-extremity pain or pares- thesias on the side that is being examined. This is a positive response on the straight-leg-raising test.

If the patient complains of pain down the opposite leg, this is called a positive crossed response on the straight- leg-raising test and is very significant for a herniated disc.

The patient may also complain of pain in the posterior part of the thigh, which is due to tightness of the hamstrings.

You can determine whether the pain is caused by tight hamstrings or is of a neurogenic origin by raising
the leg up to the point where the patient complains of leg pain, and then lowering the leg slightly. This should reduce the pain in the leg. Now passively dorsiflex the patient’s foot to increase the stretch on the sciatic nerve. If this maneuver causes pain, the pain is neurogenic in origin. If this move- ment is painless, the patient’s discomfort is caused by hamstring tightness

207
Q

Flexibility Tests:

Hip Flexor Thomas Test

3 parts

A

POSITION: Sit at edge of table and table up to buttocks and upper thigh and lie back down.
Take both knees to their chest.

TEST:
1. Person holds their R knee, bring the left leg down and see if it can make contact with the table.
=>If it doesn’t come down: there is tightness in the illiopsoas

  1. straighten the knee. If the extended knee is able to drop down then we know there is tightness in the rectus femoris because there is now less stretch on the rectus femoris and so the hip was able to drop down when it is cancelled out. (If the hip stays up then it is only the illiopsoas that is tight.)
  2. abducts hip = tight TFL
208
Q

Flexibility Tests:

Ely’s Test

  1. Test
  2. What its for
A

Rectus femoris tightness

–Patient in supine and legs hang off the table. The good leg is flexed to the chest while the other leg hangs off the table. If the knee extends it is a sign of tightness in the rec fem.

(because flexion of the opposite leg rotates the pelvis posteriorly pulling the rectus femoris)

(some people do a prone knee bend test)

209
Q

Flexibility Tests:

TFL: Ober’s Test

  1. test
  2. positive
A
  1. –Patient lays on their side and flexes the bottom leg for stability:

Abduct and extend the upper leg with knee flexed to 90, Stabilize pelvis from anteriorly tilting, Slowly lower the upper limb.

Cradle leg that you’re testing, abduct and extend bring it back to a neutral position or slightly extended. Want to see that person goes further than neutral position.

  1. —Positive: TFL tight if they do not adduct to neutral or if drift into hip flexion when you do it.
210
Q

Flexibility Tests:

A
  1. Seated Flexion Test: positive right
  2. base of Sacrum: posterior right
  3. ILA: posterior right
  4. ILA Motion: right increased in backwards bending
    * posterior torsion, look worse in extension and better in flexion
  5. Lumbar Scoliosis: left convexity
    - ->sacrum is rotated right there is left sidebending which means that in the lumbar spine there is sidebending right and rotation left
  6. Lumbar Lordosis: reduced
    - -> looks flatter because the sacral base is back so there is a reversal of lordosis
  7. Medial Malleolus Prone: SHORT RIGHT
    - ->Leg is longer on side of convexity, shorter on side of concavity

Confirmation of the Diagnosis

INJECTION

A

Injection of small volume of anesthetic and steroid into the synovial portion of the joint under fluoroscopic control

Inject SI with the anesthetic in synovial portion of the joint under flousoscopic control, if symptoms dissipate , pain goes away, can conclude the joint is the issue

If find SI is the issue, add in steroid and it become therapeutic

May be diagnostic or therapeutic

Q

ORDER OF TREATMENT

5

A
  1. Pelvis: upslip/downslip
  2. Pubs
  3. L5
  4. Sacrum
  5. Ilium
247
Q

TREATMENT

Pelvis: upslip/downslip

A

grade 5 thrust

  1. liac crest high in NWB position
  2. Look at where the IT is, sacrotuebrous ligament, both ASIS and PSIS, abductor weakness along with that
  3. Note: crest can appear higher if it has turned, don’t be fooled by patient when rotated crest which is why need to look at IT and sacrotuberous ligament as well as PMH and symptoms
  4. Upslips are very uncomfortable and patient cannot bear weight on that side –cannot sit, or stand on it. Will have a significant history fell on pothole down a step etc. something strenuous on that joint, and WB will be a significant thing for them
248
Q

TREATMENT

Pubic Symphysis

A

Shot Gun Technique

muscle energy technique: this works for superior and inferior pubs

  1. Patient in supine with knees flexed: hooklying
  2. Resist abduction approximately 3 times (for an inhibition)
  3. Resist adduction by placing your arm between the patients knees
  • Do not put olecranon into their adductor
  • Be careful of your own wrist: extended but not hyperextended
  • Don’t need maximal contraction, just enough contraction to get the muscle to pull on its origins without fx radius/ulna—feel a full contraction but not one that will hurt me
249
Q

how shot gun technique works

A

Create an isometric contraction of the adductors which attach to inferior pubic ramus: create a reversal of the origin and insertion by fixing the distal attachment and tell patient to isometrically contract so that the proximal attachment will pull inferiorly and the side that is higher will drop down lower. Usually accompanied by popping/cracking sound. Patient may be temporarily uncomfortable. Significant change after.

250
Q

TREATMENT

L5 vertebrae

A

Put the patient in prone and look at alignment of sacrum and of L5 vertebrae. L5 should be in opposite direction to sacrum because it is diametrically opposed and rotates and side-bends opposite of sacrum. In the neutral position they should be the opposite. If they are not the opposite treat L5 first. When L5 is corrected it may change what happens in the sacrum because sometimes sacrum is pulled by L5. If correct L5, sacrum may change. If L5 rotated in the wrong direction de-rotate it at SP or TP.

If no issue with L5, go straight to sacrum

257
Q

TREATMENT: Ilium

Posterior Innominate

A

Patient Left Sidelying, left lower extremity flexed for BOS

Preplace: upper leg: right lower extremity slightly extended

Force couple: Right hand on iliac crest, left hand on ischial tuberosity

  • ——Push forward with my hand on the crest
  • ——Push posteriorly with my hand on the Ischial Tuberosity

Simultaneously rotate ilium ventrally

  • ——Rotate the innominate bone from posterior to anterior position
  • ——Can then increase the extension of the uppermost leg and rotate again.
  • ——**can also do in supine like in a modified Thomas Test position: bring the right leg into extension off the table and create same fulcrum of bringing innominate bone anteriorly

combine with muscle energy technique: isometric hip flexion and she releases and I push into more extension

258
Q

Supine Posterior Innominare

A

Ilium: Posterior Innominate:

Supine: off the edge, take the leg up so she stabilizes, pull up on the iliac crest (my hand is under the iliac crest) and ask her to bring the leg gently to the ceiling (something is flexed) and as she releases I bring my hand forward –so I am pulling underneath her innominate

259
Q

Prone Posterior Innominate:

A

a. Patient prone

b. Lift from under distal femur towards ceiling (extend the leg)
- —-Since cannot put both hands on the pelvis: lift leg and pull on anterior hip flexors, then push anteriorly on the posterior iliac crest: pushing downwards as I lift up the femur
- —-Other hand moves crest of ilium in ventral-caudal direction

Muscle energy technique: she contracts isometrically to flexion and then I take up the slack and bring her into more extension as I push down on iliac crest to create forward rotation from posterior to anterior

260
Q

Ilium: Anterior Innominate

A
  1. want preplace LE in flexion to pull innominate posteriorly
    - —–Patient left sidelying
    - —–Left LE is extended as a BOS
    - —–Preplace: The right LE is flexed
    - —–Force couple: One hand on iliac crest, other hand on ischial tuberosity
  • Handhold so can pull posteriorly and get the rotation
  • Can increase the flexion to get more rotation
  • Sustained hold works nicely with this

——Simultaneously rotate ilium dorsally (posteriorly to correct the innominate)

  • —–To use muscle energy technique: to move anterior innominate posteriorly: Use hamstrings which attach to the IT:
  • Hamstrings: supine/sidelying: take paitent leg into flexion and ask patient to extend hip into my hand by activating the hamstring and the glut simultaneously, proximal attachment of the hamstring will pull on the IT, it will pull the innominate bone posteriorly, and I can manually use the force couple and rotate the innominate bone posteriorly
261
Q

Anterior Innominate

Supine

A

a. Supine:
——Hand underneath or put her over, my hand on anterior iliac crest and under her ischial tuberosity –and rotate. She can push into my shoulder to extension and as she releases I increases the amount of rotation
Anterior to posterior rotation using the hip extensor

262
Q

Anterior Innominate

Prone

A
  • —–Patient leg off side of the table
  • —–Preplace: The right LE is flexed
  • —–Force couple: One hand on iliac crest, other hand on ischial tuberosity

Can have her push back gently, and as she releases I bring her to more flexion and I rotate

I have patient above malleoli between my two knees so I can support it, holding patient in flexion. Pelvis is off the side of the table to allow me to rotate. I can manually rotate.

In this position energy technique:

Force for the hamstring, they push into me, I take up a little more slack into flexion, and rotate the pelvis

263
Q

How to use muscle energy technique

A

——Illiopsoas and Rectus: patient in Thomas test position and want to bring innominate anteriorly: resist distal femur, ask patient to go slightly to flexion without any movement because it is an isometric contraction, increase the amount of extension and also mobilize the joint : take the innominate and rotate it (can do in sidelying, supine, and prone)

——Patient in extended position, contract the muscle isometrically, take up some slack and increase amount of extension, and simultaneously rotate and mobilize the joint
Use the flexor muscle by virtue of its attachment: pt in extension, isometrically flex, take up slack and move more into extension, and simultaneously rotate and mobilize the joint using the force couple to move it from posterior to anterior

264
Q

Right rotation with left sidebending: So there is mostly posterior to anterior but also have some inferior
More the anterior and posterior for the rotations because it is a rotation
When rotate sacrum right, sidebends left
-it goes forward and drops slightly: left base goes anterior and slightly inferior
-ILA comes posterior and up a little bit

-posterior on the ILA on the side on to which it is rotating

unitlateral shears: superior inferior with the shears
more superior with the posterior on the ILA but it is more superior than it is posterior because it is a shear
