Introduction
  • Underrecognized cause of recurrent groin pain after total hip replacement
  • May be caused by
    • retained cement
    • malpositioned acetabular component 
    • limb length discrepancy
    • excessive length of screws
Anatomy

Presentation
  • Symptoms
    • groin pain 
  • Physical Exam
    • findings are subtle and may include
      • slight limp
      • tenderness in the groin. 
      • palpable snap may be detected (rare)
    • provocative tests
      • pain may be reproduced or exacerbated by resisted seated hip flexion or straight leg raise 
Imaging
  • Radiographs
    • required views
      • AP pelvis
      • AP and lateral of hip
  • CT scan
    • helpful to determine postition of prosthesis and rule out other caused of symtpoms
  • MRI
    • usually not valuable due to artifact.
Studies
  • Diagnostic injection
    • diagnostic cortisone injection into iliopsoas sheath is helpful in diagnosis
Treatment
  • Nonoperative
    • indications
      • rare - most patients require operative intervention for complete resolution of symptoms
  • Operative
    • arthroscopic iliopsoas tenotomy 
      • indications
        •  in cases of normal post-op radiographs 
    • acetabular component revision
      • indications
        • in cases of excessive anterior cup overhang

(OBQ11.167) A 62-year-old female has persistent activity related anterior groin pain 10 months after total hip arthroplasty (THA). Infection workup is negative. New radiographs are unchanged compared to the intial films provided in Figures A and B. Pain is temporarily relieved following an injection of lidocaine and cortisone into the iliopsoas tendon sheath. What is the next appropriate treatment option? Tested Concept

(OBQ10.191) A 65-year-old male complains of continued groin pain 18 months following total hip arthroplasty. The pain is worse with activity, specifically with hip extension during gait. Hip radiographs show no fracture or loosening of the components. Lab values including ESR and CRP are within normal limits, and a hip aspiration yields a nucleated cell count of 500 and no growth on culture. Which of the following is most likely to determine the nature of the continued pain? Tested Concept

Greater trochanteric bursa injection
