Abstract:
BACKGROUND:Crowe type-IV developmental dysplasia of the hip presented complete dislocation of the femoral head, significantly shortening lower limb, serious adverse development of upper segment of acetabulum and femur, and even deformity. At present, there are no reports concerning its therapeutic strategy.
OBJECTIVE:To explore the therapeutic strategy of adult bilateral Crowe type-IV developmental dysplasia of the hip.
METHODA total of 12 cases of adult bilateral Crowe type-IV developmental dysplasia of the hip, who were treated in the Department of Orthopedics, The First People’s Hospital of Changzhou from January 2000 to January 2013, were col ected. There were 5 males and 7 females, at the age of 19-47 years old, averagely 33.5 years old. After two or three weeks of skeletal traction, they received bilateral total hip arthroplasty. Hip rotation center was reconstituted at the level of the“true”acetabulum. The subtrochanteric osteotomy was performed for patients with reduction difficulty. For patients with femoral neck anteversion>40°, subtrochanteric rotary osteotomy was performed.
RESULTS AND CONCLUSION:Disappearance of hip pain, satisfied move function and normal gait were gained after operation. Lower limbs recovered to be isometric. The average leg lengthening was 3.1 cm (range, 2.5 to 4.8 cm). One patient affected sciatic nerve irritation. The average fol owed-up time was 3.5 years. No fracture, dislocation or loosening of the prosthesis appeared. The post-operative Harris Hip Score averaged 86.3. By reconstruction of the hip rotation center in the“true”acetabular level, correction of femoral neck anteversion, reconstruction of function of the abduction muscle and proper selection of prosthesis, total hip arthroplasty for adult bilateral Crowe type-IV developmental dysplasia of the hip could obtain good curative effects.
