Total hip arthroplasty for Crowe type IV developmental dysplasia of the hip combined with intertrochanteric fracture: a case report and literature review

Abstract

Abstract Background Total hip arthroplasty for Crowe type IV developmental dysplasia of the hip (DDH) is a complex procedure. Crowe type IV DDH combined with intertrochanteric frature is very rare. Case presentation A 75-year-old patient suffering from left hip pain after a fall was sent to our hospital. Plain radiographs and computed tomography scans were used to diagnose this patient with DDH combined with an intertrochanteric fracture. We conducted a total hip arthroplasty using an S-rom prosthesis following subtrochanteric shortening osteotomy in this patient, after which steel wires were used to fix the intertrochanteric fracture. The patient did not suffer any significant intraoperative or postoperative complications, and treatment was sufficient to overcome lower leg abnormalities. The patient was encouraged to resume walking with support at 3 days post-surgery, and at 6-month postoperatively he had regained the majority of his original range of motion. At 10-month postoperatively, the intertrochanteric fracture and subtrochanteric osteotomy of left femur had healed effectively,and the patient’s VAS and mHSS scores had improved significantly. Conclusions Total hip arthroplasty is an effective approach to treat patients suffering from Crowe type IV DDH combined with an intertrochanteric fracture, and can achieve satisfactory clinical outcomes.
