Table 1
Differential | Clinical Features/Orthopedic Testing | Diagnostic Imagingb |
---|---|---|
Femoroacetabular pathology | Under-recognized cause of posterior hip pain Consider especially if posterior pain presents with concomitant anterior hip pain or if posterior pain is exacerbated with hip motion | MRA (labral tear); MRI; R |
Spinal or SIJ pathology | Centralization of symptoms with repeated spinal movement favor spinal involvement and should be done to exclude spine referral Composite testing of positive thigh thrust, distraction, compression, sacral thrust, and Gaenslen test favors SIJ origin, especially when symptoms are not reproduced with spinal movement | MRI; R |
Proximal hamstring tendinopathy | Previous hamstring injury, pain with activity, and pain while seated Symptoms may mimic sciatica Active, passive, and resisted range of motion tests and tenderness with palpation | MRI; US |
Sacral stress fracture | Fatigue fracture:
| MRI; R (specific only); SS |
Piriformis syndrome | Tenderness with palpation of the muscle Positive Freiberg sign, Pace sign, Beatty sign, and FADDIRc test | Primarily used to exclude other sources of hip pain |
Obturator internus/gemelli complex tendinopathy | Similar HPE features for piriformis syndrome | Primarily used to exclude other sources of hip pain |
Ischiofemoral impingement | Often presents with concomitant anterior hip pain | MRI |
Sciatic neuropathy | Typically there is a history of total hip arthroplasty Neurodynamic testing using the straight leg raise | MRI; US |
Pudendal neuropathy | Accompanying perineal pain Symptoms elicited with palpation of inferomedial sciatic notch/ischial spine Passive internal and external rotation of the hip and resisted hip abduction and adduction at 90 degrees of hip extension may elicit symptoms | MRI; US |
CTA = computed tomographic arthrography
FABERE = flexion-abduction-external rotation, extension
FADDIR = flexion-adduction-internal rotation
HPE = history and physical examination
MRA = magnetic resonance arthrography
MRI = magnetic resonance imaging
R = radiography
RED-S = relative energy deficiency in sport
SIJ = sacroiliac joint
SS = skeletal scintigraphy
US = ultrasonography.
a Myofascial pain syndrome should be considered in each compartment.
