Re-sults The rate of misdiagnosis in this group was 28.57%. Six patients who presented with hip joint pain with or with-out morning stiffness,were misdiagnosed as having necrosis of the femoral head. Duration of misdiagnosis was 1~4 months. Conservative treatment failed for there was no obvious improvement. CT,MRI and postoperative pathological examination confirmed hip osteoarthritis due to acetabular dysplasia in 2 cases,and primary hip osteoarthritis in 4. All 6 patients were discharged after surgical treatment,and were followed up for 3 months to 1 years,and the prognosis was favorable.
