Abstract
We report two cases of one-stage correction of rotational deformities of the lower extremity. Case 1 was a 75-year-old woman with extra-articular rotational deformity of the femur and osteoarthritis of the hip joint. The femoral deformity occurred due to malunion of the femoral fracture at age 20. Corrective osteotomy of the femur and total hip arthroplasty were performed simultaneously. External rotational deformity of 50°, which was determined by preoperative computed tomography, was corrected with angulatory deformity of 22° at the apex of the angulatory deformity. The osteotomy site was fixed with Cannulok® interlocking hip prosthesis. Case 2 was a 16-year-old girl with Kniest syndrome. She had an external rotational deformity of the hip secondary to severe osteoarthritis. Derotational osteotomy of the femur at the mid-shaft was performed. The distal segment was internally rotated by 60° so that the foot progression angle was brought into normal range. The osteotomy was fixed with interlocking nailing. This patient developed delayed union at the osteotomy site, which was successfully treated with ultrasonic therapy. Both cases have had a satisfactory outcome without major complications.
