We reported a case of subtrochanteric femoral shortening osteotomy in coxa breva with total hip arthroplasty (THA). A 73-year-old woman suffering from hip dislocation (Crowe type III) had significantly limited excursion with a leg length discrepancy of approximately 60mm. We performed subtrochanteric femoral shortening osteotomy with THA, and leg lengthening by 36mm was confirmed postoperatively by X-ray examination. Bone union was achieved in the osteotomy area at 4 months after THA, and the JOA score was improved from 51 points to 76 points, without nerve paralysis. However, this procedure has some associated problems such as a complex surgical maneuver, non-union and delayed rehabilitation. Subtrochanteric femoral shortening osteotomy with THA is useful for osteoarthritis of the hip with severe contracture, high dislocation, and coxa breva.
