introduction
- tear of the labrum of the acetabulum is said to account for 20-50% of “idiopathic” hip pain where there is no obvious cause
- diagnosis is often delayed by 2 years as the labrum is not well demonstrated on US, XRay, CT or MRI scans, although a MRA scan does have better sensitivity for detecting these tears.
- arthroscopic debridement may be required for those who fail conservative Mx.
aetiology
- 5 categories of aetiology:
- trauma
- femoroacetabular impingement (FAI)
- capsular laxity/hip hypermobility
- dysplasia of the hip
- degeneration of the hip joint
clinical features
- over half are of insidious onset whilst others are acute after a precipitant or have intermittent episodes
- 90% complain of anterior hip or groin pain (esp. if anterior labral tear)
- some have anterior thigh, lateral hip or buttock pain (esp. of posterior labral tear) and may radiate to knee
- women may also have concomitant pelvic-floor pain
- may also have clicking, locking or catching, or giving way and develop hip instability
- walking, pivoting, prolonged sitting, and impact activities, such as running, often aggravate symptoms
- most have night pain
- most commonly reported ROM limitation was in rotation, but hip flexion, adduction, and abduction ROM limitations also have been reported
- positive anterior hip-impingement test may be present
- performed with the patient supine with the hip and knee at 90° of flexion.
- hip is internally rotated while an adduction force is applied.
- positive test results in pain provocation in the anterolateral hip or groin
- positive posterior hip impingement test may be present
- patient lies prone with hip and knee extended and the examiner passively extends, adducts, and externally rotates hip
- positive test reproduces anterior hip or posterior pelvic pain
- physical exam findings remain inconsistent, likely because of the variable locations of labral tears
investigation
- US, XRay to exclude other pathology
- MRA is the best Ix currently to show labral tears
management
- physiotherapy
- if fails to settle with conservative treatment, then referral for possible arthroscopic debridement is indicated
