The biomechanical impact of long femoral nail curvature on insertion, extraction and nail deformation: A cadaveric and finite element study

This project investigated the impact of femoral nail curvature on the ease of nail insertion, extraction and overall fit. Results from the cadaveric experiment showed that nails with curvature which closely match patient's anatomy are easier to insert and remove, and have a better overall fit after implantation. This finding supports the idea of further reducing the nail curvature for populations with strong bowed femora. The finite element study conducted in this project demonstrated that the interference fit method can be potentially used to quantitatively evaluate the performance of new nail designs in the future
