保留梨状肌对髋关节置换术后康复的影响

Effect of preserving piriformis on rehabilitation after hip arthroplasty

目的探讨保留梨状肌对人工双极股骨头置换术后康复的影响。方法收集2020年1月-2022年12月因股骨颈骨折行人工双极股骨头置换术患者97例,随机分为保留梨状肌组(47例)和未保留梨状肌组(50例)。对比分析2组手术时间、术中失血量、术后肢体长度变化、术后1月、3月髋关节Harris评分等。结果保留梨状肌组在手术时间、术中失血量、肢体长度变化、术后1月HHS等方面均优于未保留梨状肌组,差异有统计学意义(P<0.05)。结论保留梨状肌人工双极股骨头置换可有效缩短手术时间、减少术中出血量,能有效控制双下肢不等长,利于术后早期髋关节功能恢复。

Objective To discuss the effect of preserving piriformis muscle on rehabilitation after hip arthroplasty.Methods From January 2020 to December 2022,97 patients who underwent hemiarthroplasty due to femoral neck fracture were selected and randomly divided into two groups with preserving piriformis group(47 cases)and without preserving piriformis group(50 cases).The operation time,intraoperative blood loss,postoperative change of lower limbs length,hip Harris Score(1,3 months follow-up after operation)were compared between the two groups.Results The group with preserving piriformis was superior to the group without preserving piriformis in terms of operation time,intraoperative blood loss,change of lower limbs length,HHS(postoperative 1 month),and the differences was statistically significant.Conclusions Hip hemiarthroplasty of preserving piriformis can effectively shorten the operation time,reduce the amount of intraoperative blood loss,effectively control leg length discrepancy of both lower limbs,and facilitate the early recovery of hip joint function after surgery.
