XXXX guide for total hip arthroplasty.

@entity1 @entity3656 @entity2249 @entity572 @entity282
BACKGROUND: @entity572 ( @entity572 ) is a common last-resort treatment for @entity572 , but postoperative @entity1 often complain of discrepancies in leg length. This study introduces a device designed to increase the precision of the @entity2249 and reduce the incidence of @entity3656 . METHODS: Forty-eight @entity1 undergoing @entity572 were divided into two groups, with and without the use of the femoral osteotomy guide. All operations were performed through a posterolateral approach. Differences in leg length were recorded before and after the operation. Measurements were also made to compare the preoperative plan with the actual amount of bone removed. RESULTS: The mean average difference in femoral neck resection height was 0.84  mm when using the osteotomy guide and 1.69  mm without the guide. @entity282 were 5.45  mm and 13.37  mm in the groups with and without the guide, respectively. CONCLUSION: The @entity2249 guide is an effectively auxiliary tool for increasing the accuracy of bone resection in arthroplasty using the posterolateral approach.
