The aim of this study is to retrospectively evaluate the efficacy of 3D navigational template for Salter osteotomy of DDH in children.
Thirty-two consecutive patients with DDH who underwent Salter osteotomy were evaluated between July 2014 and August 2017, and they were divided into the conventional group ( = 16) and navigation template group ( = 16) according to different surgical methods. The corrective acetabular degrees, radiation exposure, and operation time were compared between the two groups.
No nerve palsy or redislocation was reported in the navigation template group. Compared with the conventional group, the navigation template group had the advantages of more accurate acetabular degrees, less radiation exposure, and shorter operation time ( < 0.05). Meanwhile, the navigation template group achieved a better surgical outcome than the conventional group (McKay, = 0.0293; Severin, = 0.0949).
The 3D navigational template for Salter osteotomy of DDH is simple and effective, which could be an alternative approach to improve the Salter osteotomy accuracy and optimize the efficacy.
本研究旨在回顾性评估 3D 导航模板在儿童发育性髋关节脱位（DDH）Salter 截骨术中的疗效。
2014 年 7 月至 2017 年 8 月，连续评估了 32 例接受 Salter 截骨术的 DDH 患者，根据不同的手术方法将其分为常规组（n = 16）和导航模板组（n = 16）。比较两组患者的髋臼矫正度数、射线暴露量和手术时间。
导航模板组无神经麻痹或再脱位发生。与常规组相比，导航模板组具有髋臼矫正度数更准确、射线暴露量更少、手术时间更短的优势（<0.05）。同时，导航模板组的手术效果优于常规组（McKay，=0.0293；Severin，=0.0949）。
3D 导航模板在 DDH 的 Salter 截骨术中简单有效，可作为提高 Salter 截骨术准确性和优化疗效的替代方法。
