Q

Ligamentum Teres

A

Predominantly arises from the transverse acetabular ligament (inferior margin of the acetabulum)
Attached to the periosteum by 2 bands (ischial and pubic margin of the acetabular notch)
Flat near the acetabular and roundish on its femoral attachment (Fovea capitis)
Length 30 – 35 mm

Q

Ligamentum Teres function

A

Evidence is lacking
– Strong, bundled and intraar1cular
– Can be considered as the ACL of the knee
– Taut when the hip is in its least stable posi1on (flexion/ adduc1on/external rota1on)
– Nocicep1on and coordina1on movement (because of its innerva1on)
– Provide blood supply to the developing hip joint
– Windshield wiper effect (synovial distribu1on)
– Pa1ents usually report an hyperabduc1on type of injury

Q

Osteoarthritis (OA) of the Hip

A
  • Insidious onset of dull ache in anterior hip/groin
    • Symptoms located in part in the L3 dermatome
    (groin, anterior thigh, the knee and the leg as far as the ankle)
    • Sometime may present as unilateral lower back pain
    • > 50 years
    • Morning stiffness which eases with movement which become continuous, can disturb sleep
  • Exacerbated by weight bearing and cold weather
    • Can be primary or secondary (90%) to trauma, bony abnormality or inflamma1on / infec1on
    • Presents with a capsular paFern at the hip (internal rota1on most limited, flexion, extension and abduc1on*)

In early stage
– Capsular stiffening (internal rotation, flexion, abduction and extension)
– Lost of the elastic end-feel In more advanced stage
– Gross limitation with loss of all rotational movement
– Functional is predominantly in flexion/extension – Hard end-feel associated with crepitus

Hip Impingement

A

Abutment between the proximal femur and the rim of the acetabulum
Most oqen occur anteriorly with flexion and rota1on of the hip
Can start in adolescent or adulthood, gradually progressing and can injure the labrum and the car1lage (ADL)

Q

Femeroacetabular impingement

A

FAI is a common cause of labral injury and has been iden1fied as being a major factor in hip OA as with hip dysplasia.
FAI is mainly related to 2 components:
– Morphological abnormali1es (head/neck/ acetabular)
– Repeated hip flexion
… Resul1ng in an impingement of the
femoral neck on the labrum

Q

Diagnosis of a patient with hip impingement

A

As such… the diagnosis rests on 3 converging lines of evidence
1. Pattern of pain
2. + impingement maneuver
3. Imaging study
a. Cam-effect (66 – 75%)
b. Pincer effect (25%)
c. Mixed-type (prevalence 19 – 42% to 80%)
Impingement test: FADIR pain is a positive for hip impingement

Q

The labrum

A

The labrum is analogous to the Knee meniscus and GH labrum
Func1on:
1. Enhance joint stability(seal)
2. ↓force transmitted to the articular cartilage

  1. Proprioceptive feedback
    The joint capsule is supported by:
  2. Pubofemoral(inferiorly)
  3. Ischiofemoral(posteriorly)
  4. Iliofemoral(anteriorly)

Q

How an acetabular tear occurs

A

Shearing force that occur with
• Twisting
• Pivoting, and
• Falling
Because of its innervation (free nerve ending), labral tear will likely produce pain
North America: Anterosuperiorly (twisting/ pivoting)
Asian: posteriorly (hyperflexion/squatting motion)

  2. Radial fibrillated
  3. Longitudinal peripheral
  4. Abnormally mobile
    Most commonly occur in an anterior and anterosuperior loca1on
    Mechanism of injury oqen relates to an external rota8on force in a hyperextended hip positon or repe88ve microtrauma associated with twis8ng and pivo8ng.

Q

Aetiological Factors of avascular necrosis

A

Most cases of AVN are atrauma8c and include the following:
• Excessivecor1costeroidusageandalcoholabuseaccountforas many as 90% of new cases
• Coagula1onsecondarytovesselwallinjury(eg,chemotherapy, radia1on), or a thromboembolic event (eg, fat emboli)
Traumatic causes of femoral head AVN include the following:
• Femoral neck fractures
• Hip disloca1on
• Slipped capital femoral epiphysis(SCFE)

26
Q

Treatment for avascular necrosis

A

Conservative treatment = yields unfavorable results
Physical therapy = symptomatic control ≠ disease progression
Surgical treatment
– Prophylactic measures (to retard progression) or
– Reconstruction procedures (aqer femoral head collapse)

27
Q

“Snapping Hip” Syndrome

A

Benign, painless snapping in the hip is common in the general population
Symptoma8c snapping hip with debilitating pain and weakness is oqen seen in athletes
3 types:
1. External/Lateral (ITB)

  1. Internal (iliospoas)
  2. Intraar1cular (Labral)
28
Q

External snapping syndrome

A

Posterior fibers of ITB or ant fibers of gluteus max
moving over the greater trochanter in flex/ext
– “snap” may be palpable/audible/both
– Trochanteric bursitis may ensue

29
Q

Internal snapping syndrome

A

Occurs when the iliopsoas tendon in the flexed, abducted and externally rotated hip moves to a position medial to the hip capsule during extension

30
Q

Intra-articular snapping syndrome

A

Usually loose bodies or labral tears
Symptomatic snapping hip is diagnosed through
– History
– Local palpation with ROM for the “snap”
– RIM muscle testing should reveal pain/weakness
– Ortho tests that focus on muscles pathology

31
Q

GREATER TROCHANTERIC PAIN SYNDROME

A

Describe pain and tenderness in the region of the greater trochanter and the juxtaposed soft tissues of the buttock and lateral proximal thigh
Estimated that 10 – 25% of the general population will develop lateral hip pain
Common misconcep1on of the ae1ology of lateral hip pain… incomplete treatment approach… temporal relief

32
Q

Causes of greater trochanteric pain syndrome

A

• Most common causes is hip abductor tendinopathy

– Gluteus Medius and Minimus
• Trochanteric bursitis in not usually the most common cause of GTPS

33
Q

Tests for greater trochanteric pain syndrome

A

• FABER +++
• End-range adduc1on
• Typically not aggravated by passive hip internal rota1on

– + 30s single-leg stance (SN 100%/SP 97.3%)
– + Resisted external derota1on test (SN 88%/SP 97.3%) – + Trendelenburg test (SN 73%/SP 77%)
– Ober test
– Hip lag-sign

34
Q
