BACKGROUND
Fossa piriformis is considered the correct point of entry for a straight femoral nail. A trochanteric overhang may make the access to fossa piriformis difficult. We investigated the anatomy of the trochanteric region, paying special attention to the entry point for antegrade intramedullary femoral nailing.
METHODS AND RESULTS
We studied 100 cadaver specimens. In 63 specimens a shape with a free entry point was found, whereas in 37 cases the entry point was either half or fully covered. In 9 specimens the entry points could not be exactly located from a cranial aspect.
INTERPRETATION
The anatomic variations of the trochanteric sometimes make it difficult to identify the correct entry point for an intramedullary nail.
背景
梨状窝被认为是直型股骨钉正确的进针点。转子部的骨赘可能会使进入梨状窝变得困难。我们研究了转子区的解剖结构，特别关注股骨顺行髓内钉固定的进针点。
方法与结果
我们研究了100具尸体标本。在63个标本中发现有一个自由进针点的形状，而在37个病例中，进针点部分或完全被覆盖。在9个标本中，从颅侧无法准确确定进针点。
解读
转子部的解剖变异有时会使确定髓内钉的正确进针点变得困难。
