Pelvic osteotomies for acetabular dysplasia include an osteotomy of the ischium. The potential anatomical hazards of three different osteotomies of the ischium were assessed by performing a triple osteotomy in a series of 8 fresh cadaver pelvises. An oblique osteotomy above the sacrospinous ligament using a posterior approach requires that the inferior gluteal and pudendal neurovascular bundles be mobilised and retracted. A transverse osteotomy below the sacrospinous ligament using a posterior approach can be performed in a relatively safe area between the pudendal and sciatic nerves. A transverse osteotomy from anterior can be performed through a modified Smith Peterson approach. The pudendal nerve medially, the sciatic nerve laterally and the medial circumflex artery distally are not visualised and are prone to damage.
用于髋臼发育不良的骨盆截骨术包括坐骨截骨术。通过在8个新鲜尸体骨盆上进行三联截骨术，评估了三种不同坐骨截骨术潜在的解剖学风险。采用后路在骶棘韧带上方进行斜行截骨术时，需要游离并牵开臀下神经血管束和阴部神经血管束。采用后路在骶棘韧带下方进行横行截骨术可在阴部神经和坐骨神经之间相对安全的区域进行。经改良的Smith Peterson入路可从前侧进行横行截骨术。阴部神经在内侧、坐骨神经在外侧、旋股内侧动脉在远端无法直视，且容易受损。
