Abstract

INTRODUCTION

The purpose of this study was to compare patient-specific acetabular cup target orientation using functional simulation to the Lewinnek Safe Zone (LSZ) and determine associated rates of postoperative dislocation.

METHODS

A retrospective review of 1500 consecutive primary THAs was performed. Inclination, anteversion, pelvic tilt, pelvic incidence, lumbar flexion, and dislocation rates were recorded.

RESULTS

56% of dynamically planned cups were within LSZ (p < 0.05). 6/1500 (0.4%) of these cups dislocated at two year follow-up, and all were within LSZ.

CONCLUSION

Optimal acetabular cup positioning using dynamic imaging differs significantly from historical target parameters but results in low rates of dislocation.

LEVEL OF EVIDENCE

Level III: Retrospective.

摘要

引言

本研究的目的是使用功能模拟将患者特异性髋臼杯目标方向与Lewinnek安全区（LSZ）进行比较，并确定术后脱位的相关发生率。

方法

对1500例连续的初次全髋关节置换术进行回顾性研究。记录倾斜度、前倾角、骨盆倾斜度、骨盆入射角、腰椎前屈度和脱位率。

结果

56%动态规划的髋臼杯位于LSZ内（p<0.05）。在两年随访时，这些髋臼杯中有6/1500（0.4%）发生脱位，且均在LSZ内。

结论

使用动态成像的最佳髋臼杯定位与既往目标参数有显著差异，但脱位率较低。

证据水平

III级：回顾性研究。
