The femur 3D model created by computer software was imported to a computer-aided design software package to analyze the medullary morphology. Center edge angle (CE angle), Sharp angle, femoral head diameter (FHD), and the offset were measured. The femoral neck isthmus space (FNIS), which is the narrowest part of the femoral neck, at neck-shaft angles of 125°, 130°, and 135°, was also measured.\nResults: In the N group, CE angle was 36.2°, Sharp angle was 39.8°, FHD was 42.6 mm, and offset was 39.5 mm. In the DH group, CE angle was 24.7°, Sharp angle was 46.1°, FHD was 45.2 mm, and offset was 33.6 mm. Each parameter was significantly different between the groups.

内容記述 | Introduction: The purpose of this study was to analyze proximal femoral morphology in Japanese persons using computed tomography (CT) data. Materials and methods: Data from 19 normal hips (N group) and 19 dysplastic hips (DH group) in women who underwent total hip arthroplasty were randomly selected from a CT database. The femur 3D model created by computer software was imported to a computer-aided design software package to analyze the medullary morphology. Center edge angle (CE angle), Sharp angle, femoral head diameter (FHD), and the offset were measured. The femoral neck isthmus space (FNIS), which is the narrowest part of the femoral neck, at neck-shaft angles of 125°, 130°, and 135°, was also measured. Results: In the N group, CE angle was 36.2°, Sharp angle was 39.8°, FHD was 42.6 mm, and offset was 39.5 mm. In the DH group, CE angle was 24.7°, Sharp angle was 46.1°, FHD was 45.2 mm, and offset was 33.6 mm. Each parameter was significantly different between the groups. FNIS was 21.8 mm, 22.1 mm, and 22.1 mm, respectively, in the N group and 21.7 mm, 21.6 mm, and 21.5 mm, respectively, in the DH group. Discussion: This is the first report to clarify the medullary morphology of the proximal femur in Japanese women. Results show that there is sufficient space for currently available implant to fit in. This study also elucidated the morphologic characteristics of dysplastic hip, which will be useful information in developing hip prostheses and fixation devices suitable for Asian patients. |
