GEOMETRIC MISMATCH OF THE GAMMA-NAIL TO THE CHINESE FEMUR

The geometric mismatch of the femoral component of the Gamma nail to t he Chinese femora resulted in intraoperative complications. To provide scientific data for modification of the implant, 28 pairs of normal C hinese femora were studied with the 3-dimensional reconstruction from the computed tomography scan data. Measurements were taken from the re constituted drawings, and the anthropometric data were applied in the modification of the implant. This study is the first report on the app lication of Chinese anthropometric data on the design of a trauma impl ant. It is hoped that a larger scale of the study will provide a more comprehensive data base for wider application to orthopaedic implant d esign in the future.
