: This study reports the results of 2 separate surveys of British Hip Society (BHS) members relating to leg length inequality (LLI) after primary total hip replacement (THR).
SURVEY 1:: Investigates the members' opinions on the effect of LLI on the outcome of THR and explores the acceptable limits of LLI.
SURVEY 2:: Reports on the intraoperative techniques currently used by BHS members to minimise LLI after THR.
RESULTS - SURVEY 1:: 97% of all surgeons completing the survey believed that LLI can affect the outcome of THR.
RESULTS - SURVEY 2:: All surgeons reported using at least 1 intraoperative technique for assessing leg length with a median of 5 techniques. Over 50% of surgeons use 2 or more tests.
CONCLUSION - SURVEY 1:: 89% of surgeons agreed that 15 mm of LLI after primary uncomplicated THR was always acceptable. 90% of surgeons felt that LLI more than 22.74 mm was never acceptable.
CONCLUSION - SURVEY 2:: Despite the multiple published papers on various methods of assessing leg length intraoperatively, the problem of LLI post THR persists. This study highlights the need for further research to develop a simple intraoperative technique with high accuracy and reproducibility.
本研究报告了针对英国髋关节协会（BHS）成员进行的两项关于初次全髋关节置换（THR）后下肢长度不等（LLI）的独立调查结果。
调查1：调查成员对LLI对THR结果影响的看法，并探讨LLI的可接受限度。
调查2：报告BHS成员目前在THR后用于最小化LLI的术中技术。
结果 - 调查1：完成调查的所有外科医生中有97%认为LLI会影响THR的结果。
结果 - 调查2：所有外科医生均报告至少使用1种术中技术评估下肢长度，中位数为5种技术。超过50%的外科医生使用2种或更多测试。
结论 - 调查1：89%的外科医生同意初次无并发症THR后15 mm的LLI始终是可接受的。90%的外科医生认为超过22.74 mm的LLI永远不可接受。
结论 - 调查2：尽管有大量关于术中评估下肢长度各种方法的已发表论文，但THR后LLI的问题仍然存在。本研究强调需要进一步研究以开发一种具有高准确性和可重复性的简单术中技术。
