Abstract:Introduction: Femur is the longest and strongest bone of the human body &has a very important role in mechanism of weight bearing and locomotion. The upper end has a head, which is connected to shaft by neck. The neck shaft angle is the angle between the long axis of femoral shaft & axis of the femoral neck. A detailed study on the neck-shaft angle, the femoral neck length and the relation between them is essential for clinical procedures in the hip region.
Material & Method: 90 intact dry femur without any deformity were studied. Femoral neck length was measured using a slide caliper. This angle was measured with help of goniometer. Data was charted and statistical analysis was done using SPSS version 16.0.
Result: The overall mean NL was found to be 2.93± 0.12cm (right side was 3.02±0.07cm &left side was 2.85± 0.09cm). The mean NL of the right side was more as compared to left side, the difference was not significant. The overall mean NSA was found to be 129.00•± 1.54(right side was 129.87•±1.42, left side was 128.13•±1.09). The NSA of right side was greater than the NSA on left side but the difference was not significant. The correlation between the NL&NSA was found to be significant.
Conclusion: There is significant positive correlation between the femur NL and NSA of the corresponding bone. This study will be helpful while performing various clinical procedures in this region.
