The objective of this study was to compare anterior and posterior pin placement of the pelvic C-clamp with specific reference to the proximity of the sciatic nerve, sciatic notch, hip joint capsule, and superior gluteal neurovascular bundle.
The pelvic C-clamp (Synthes, Paoli, PA) was applied to eight extracted pelvic specimens and five full cadavers (26 hips in total). Anterior and posterior pin placements were measured in relationship to the described anatomical structures.
In 100% of the hips the distance from the posterior pin to the hip joint capsule was in 21 (80.8%), 23 (88.5%), and 20 (76.9%) of the hips, the anterior pin distances were greater than the posterior pin distances to the sciatic nerve, sciatic notch, and superior gluteal neurovascular bundle, respectively.
Anterior pin placement is further from all anatomical structures studies with the exception of the hip joint capsule. The posterior pin was closer to the sciatic nerve, sciatic notch, and superior gluteal neurovascular bundle in all cases. Clinical decision-making for C-clamp placement should be individualised on a case-by-case basis.
本研究的目的是比较骨盆C形夹前后进针位置，特别关注坐骨神经、坐骨切迹、髋关节囊和臀上神经血管束的接近程度。
将骨盆C形夹（辛迪思公司，宾夕法尼亚州波利）应用于8个离体骨盆标本和5具完整尸体（共26个髋关节）。测量前后进针位置与上述解剖结构的关系。
在100%的髋关节中，后针到髋关节囊的距离在21个（80.8%）、23个（88.5%）和20个（76.9%）髋关节中，前针到坐骨神经、坐骨切迹和臀上神经血管束的距离分别大于后针到这些结构的距离。
除髋关节囊外，前针进针位置离所有研究的解剖结构更远。在所有情况下，后针更靠近坐骨神经、坐骨切迹和臀上神经血管束。骨盆C形夹放置的临床决策应根据具体情况个体化。
