| Abstract: | We hypothesized that the contact area of the articular surface of the wrist joint could be evaluated using a custom-designed analytical program. The aim of the study was to compare the articular contact area of the wrist joint before and after radial shortening osteotomy for Kienbock's disease. Nine wrists of 9 patients underwent radial shortening osteotomy for Kienbock's disease. Computed tomography (CT) images of the wrist joint were reconstructed using a 3D reconstruction software package. Radioscaphoid and radiolunate joint contact areas and translation of the joint contact area from preoperative to postoperative were calculated using customized software. The mean Modified Mayo Wrist Score was significantly improved from 50.6 preoperatively to 83.3 at final follow-up (p < .001). Preoperatively, the pain was reported as severe in five wrists and moderate in four wrists, while at final follow-up, five patients were free from pain and four patients had mild pain with vigorous activity. The preoperative radioscaphoid joint contact area was 133.4 +/- 49.5 mm(2) and the postoperative radioscaphoid joint contact area was 156.4 +/- 73.1 mm(2). The preoperative radiolunate joint contact area was 194.8 +/- 92.1 mm(2) and the postoperative radiolunate joint contact area was 148.3 +/- 97.9 mm(2). The radial translation distance was 0.4 +/- 1.2 mm, the dorsal translation distance was 0.6 +/- 1.2 mm, and the proximal translation distance was 0.2 +/- 0.4 mm. CT-based analysis revealed that the center of the contact area translated radially following radial shortening. |
