The effect of remaining trapezial space on outcomes after trapeziectomy with ligament reconstruction tendon interposition for trapeziometacarpal osteoarthritis.

Ligament reconstruction and tendon interposition (LRTI) procedures for trapeziometacarpal osteoarthritis aim to prevent proximal metacarpal migration to improve thumb function. We sought to evaluate the effect of the remaining trapezial space on outcomes after trapeziectomy with LRTI. Forty-seven patients were included in this study. Patients were evaluated clinically and radiologically. They were divided into two groups according to the remaining trapezial space at last follow-up. Postoperative to preoperative trapezial space ratio was >50% in group 1 and <50% in group 2. Mean follow-up was 30.8 months. Mean age, sex, dominant side, preoperative stage, and follow-up were similar in both groups. The mean QuickDASH scores were significantly better in group 1 than group 2. Mean tip and key pinch were significantly stronger in group 1, than group 2. Trapeziectomy with LRTI is the most used surgical technique and it produces satisfactory results. Improved clinical outcomes can be achieved when more than 50% of the preoperative trapezial space remains.

Triple pelvic osteotomy for the treatment of symptomatic acetabular dysplasia in adolescents and adults : A review of 42 hips.

We treated 42 hips with symptomatic acetabular dysplasia using triple pelvic osteotomy. The mean age of the patients was 20.7 years (12-47). The median follow-up was 50.3 months. The average Harris hip score improved from 74 to 92 points. Significant improvement from the preoperative to the latest follow-up evaluation was seen radiologically with reference to the center-edge angle, the anterior center-edge angle, the acetabular index and the femoral head extrusion index. Shenton's line was intact in 9 hips before the operation and it was intact in 40 hips at the latest follow-up. The cross-over sign was present in 15 hips before the operation and it was present in one hip after the operation. The results of this study demonstrated that triple pelvic osteotomy provides improved radiographic results and good symptomatic relief in acetabular dysplasia.
