Clinically Relevant Anatomy[edit | edit source]
The labrum of the hip is responsible for deepening the acetabulum to provide increased joint stability. It contains nerve endings to enhance proprioception, but may also be a source of pain.
Epidemiology /Etiology[edit | edit source]
The labrum is susceptible to traumatic injury from shearing forces that occur with twisting, pivoting and falling. The most common mechanism is an external rotation force in a hyperextended position.
Characteristics/Clinical Presentation[edit | edit source]
Symptoms may include pain, clicking, locking, catching, instability, giving way, and/or stiffness. A labral tear commonly refers pain to the anterior groin.
Labral tears have been classified into 4 types:
- radial flap: most common, disruption of free margin of the labrum
- radial fibrillated: fraying of the free margin, associated with degenerative joint disease
- longitudinal peripheral: least common
- abnormally mobile: can result from a detached labrum
Differential Diagnosis
[edit | edit source]
Chondral lesion, osteoarthritis, hip dysplasia, Legg-Calve Perthes, Slipped Capital Femoral Epiphysis, trochanteric bursitis, psoas bursitis, stress fracture, lumbar radiculopathy, piriformis syndrome, avascular necrosis
Diagnostic Procedures[edit | edit source]

MRa is thought to be the diagnostic imaging of choice to evaluate an acetabular labral tear.
