Sources of Hip Pain

Sources of Hip Pain
Sports hernia (core injury
Osteitis pubis
Lumbar spine / SIJ
Pain referred to hip region/Intra-articular)
Pain referred to hip region
Iliotibial Band Syndrome (ITBS)
People complain of pain in the (medial/lateral) hip/knee.
lateral
Iliotibial Band Syndrome (ITBS)
Most common cause of (medial/lateral) knee pain
2nd most common cause of knee pain in runners
Occurs in cyclists frequently
(15% of overuse injury)
lateral
Lateral Hip / Knee Pain Differential Diagnosis
PFPS DJD lateral compartment Lateral meniscal pathology LCL sprain Superior tib-fib joint sprain Popliteal or biceps femoris tendonitis Common peroneal nerve injury
Referred pain from lumbar spine
What Level?
L5
ITBS
Clinical Presentation
Pain 2 cm (above/below) lateral joint line - (femoral epicondyle)
Usually at same point (after/of) run / bike - (irritation w/ repetition)
Stabbing / sharp pain - may not be able to continue
up/down stairs
after sitting for a period of time
Pain (increases/diminishes) with rest
above; of; diminishes

ITB Anatomy
____ crest to (inferior/superior) aspect of lateral femoral epicondyle, then again at ______ tubercle
Unattached portion where it crosses knee joint
iliac; superior; Gerdys
Got it
Got it
ITB is a thickening of the _____ lata
fascia
What attaches to the ITB?
Gluteus (maximus/minimus
TFL/Vastus intermedius)
(Medial/Lateral) retinaculum of the patella
maximus; TFL; lateral
The ITB attaches the full length of the femur
Got it
ITBS
Small portion where ITB is not attached
People have pain (above/below) the joint line
above
ITB Anatomy
“Tendon” portion - Attachment to femur
“Ligament” portion - Controls tibial (EROT/IROT)
Tendon connects muscle to bone – the muscle being the TFL – bone being the femur .
Ligament attaches bone to bone – tibia and femur
IROT
MR of distal femur
Layer of fat tissue deep to ITB: (Highly/Lowly) innervated (Highly/Lowly) vascular Pacinian corpuscles (BURSA/NO BURSA) PRESENT
At _° knee flexion, ITB compresses fat layer below against fem epicondyle
Lot of pain receptors due to being highly vascular
If you constantly compress that area it will be irritated.
Highly; Highly; NO BURSA; 30;
Iliotibial Band Syndrome
Biomechanical Etiology – Current Concept (Fairclough et al., 2006, 2007)
IT band is attached to the distal femur and cannot rub on epicondyle
IT band is compressed against epicondyle during movement
Tibial IROT occurs on femur with knee (flexion/extension)
Tibial IROT (decreases/increases) compression
Pain due to compression of fat layer under ITB vs repetitive friction
flexion; increases;
ITBS Risk Factors
Cyclists
Toe (in/out) position – pedals
Saddle too high, too far back
Bike fit?
Bike fit – can cause irritation of the IT band.
Toe in – (decreases/increases) internal rotation
in; increases;
ITBS
Clinical Tests
(+/ +/-) Noble compression test
Common: (+/ +/-)Thomas test
(+/ +/-) Ober’s test?
+; +; +/-
Clinical Findings in ITBS
significantly (higher/lower) Ober measurement (1.2°)
weaker hip (internal/external) rotator strength (1.2 Nm/kg)
Greater hip (internal/external) rotation motion (3.7°) Peak motion while running
lower; external; internal;
ITBS Biomechanics
Increased (ABD and EROT/ADD and IROT) at mid stance
(IROT/EROT) of leg increases with fatigue during running
ADD and IROT; IROT
Biomechanics to Consider
Associated with ITBS
(Narrow/Wide) Step Width - (cross over pattern)
Narrow
Step Width
Got it
Narrow Step Width
Narrow: >25% of heel is medial to vertical line from L5 spinous process.
This leads to (decreased/increased) ITB peak strain and strain rate
increased;
Step Width
Increased Step Width:
Reduced
Peak hip (adduction/abduction)
Peak rear foot (inversion/eversion)
ITB strain
adduction; eversion
ITBS
Biomechanical targets for rehabilitation:
With ITBS there is a Large hip (adduction/abduction) angle / (medial/lateral) collapse of hip:
Target weak hip (adductors/abductors), poor activation / neuromuscular control of the hip
-Narrow step width:
Modify running technique
adduction; medial; abductors;
ITBS Treatment Concepts
Start with basic movements like lunges, squats, etc
Got it
No US, doesn’t work
Local pain and acute – (local as in pointing to the spot) – iontophoresis is (bad/good)
good
Injection - (Acute/Chronic) and painful
Acute
ITBS Treatment
Stretch?
1 and 2 joint hip flexors
WHY? - Restricted hip flexor length (Thomas test) demonstrated (increased/decreased) gluteal activation
Self stretch
Contract- relax
Active stretch
Thomas test is positive – restricted hip (flexor/extensor) length
People with tight hip flexors don’t use their glutes well
Maintain core stability – if go into lumbar extension when doing these stretches then it will (increase/decrease) the stretch.
decreased; flexor; decrease;
This relates to IT band syndrome = if you don’t have motion north south, you’ll go east west. That will lead to _____ valgus.
dynamic
Can prob stretch the TFL, but not really the IT band.
Got it
What is the best ITB stretch out of the three pics?
The middle one
Probably not able to stretch the ITB
Got it
Look at the fascia all around that area.
Try to (stabilize/mobilize) the tissue
mobilize

Not the focus of treatment, but helps pts feel better.
ITB strap – redirects the force through the area that is compressed. Similar to thing used for LET. Indications - Pain that is limiting their function or trying to get through a race
Got it
ITBS Treatment Concepts
Prevent (sagittal/frontal and transverse) plane instability
Promote a “neutral” hip, knee position: Avoid excessive (ADD/IROT/ ABD/EROT)
frontal and transverse; ADD/IROT
