Table 3
Differential | Clinical Features/Orthopedic Testing | Diagnostic Imagingb |
---|---|---|
Hip OA | Anterior or posterior hip pain Persistent deep groin pain that is worse with activity Increased pain on internal rotation, and concurrent morning stiffness lasting <60 minutes. Hip internal rotation of <15° with a coexisting limitation of flexion less than or equal to 115° Trendelenburg sign, resisted hip abduction, and FABERE tests | MRI; R |
FAI | More prevalent in athletes (eg, hockey, soccer, dance, and golf) Persistent stiffness and intermittent groin pain during early stages Later stages may reveal sharp pain and mechanical symptoms (ie, catching, locking, instability) Flexion, adduction, and internal rotation and flexion internal rotation tests have high sensitivity only Thomas test has high sensitivity and specificity for intra-articular pathology | MRA; R |
Acetabular labral tear | Different types of tears exist (post-traumatic; associated with FAI; capsular laxity/hip hypermobility; dysplasia; and degenerative) Central groin and peritrochanteric pain more common. Unlikely to present with anterior thigh or ischial pain (compare with OA). Flexion, adduction, and internal rotation and flexion internal rotation tests have high sensitivity only Thomas test has high sensitivity and specificity for intra-articular pathology If clicking, catching, or locking of the femoroacetabular joint occur during testing likelihood of labral tear is increased | CTA; MRA |
Internal snapping hip | Reproducible snap with hip flexion and concomitant pain | US |
Stress fracture | Both fatigue and insufficiency stress fractures of the femoral neck, pubic rami, or acetabulum may cause anterior hip pain. For all stress fractures, a high index of suspicion is paramount for early detection Femoral neck:
Pubic rami:
Acetabulum:
| MRI; R (specific only); SS |
ONFH | Associated conditions (ie, trauma, corticosteroid use, alcoholism), although commonly idiopathic Deep groin pain accentuated with axial loading of the femur Evaluate the contralateral hip in nontraumatic cases | MRI; R |
Hip joint laxity | Seen more commonly in female ballet dancers and gymnasts Beighton scale may be appropriate to evaluate global hypermobility Anterior, posterior, lateral hip apprehension tests Often associated with anterior impingement | MRA; MRI |
Inguinal disruption (athletic pubalgia) | Anterior hip pain in an athlete not originating from the femoroacetabular joint Male athletes more common Point tenderness over the pubic tubercle and conjoint tendon Pain exacerbated with a resisted curl-up, resisted hip flexion and/or adduction, and the Valsalva maneuver Adductor squeeze test performed in 90° of hip flexion demonstrates high sensitivity but low specificity for pubic aponeurosis and adductor pathology Exclude inguinal hernia | CTA; MRI; US |
Femoral, obturator, ilioinguinal, and genitofemoral neuropathy | Consider if prior hip replacement or inguinal hernia surgery Neurodynamic testing with the femoral nerve tension test | MRI; US |
