| Fractures of the Proximal Femur (hip) (4432 words) |
 | In younger patients, proximal femoral fractures are usually the result of high-energy physical trauma (e.g., high-speed motor vehicle accidents) and usually occur in the absence of disease. |
| Proximal femoral fractures in elderly patients are often pathologic, usually resulting from minimal-to-moderate physical trauma to areas of bone significantly affected by osteoporosis. |
| Optimally, the end of the lag screw should be placed in close proximity to the apex of the femoral head so that the sum of the distances between the end of the screw and the apex of the femoral head in the AP and lateral views is less than 20 to 25 mm. |
