INTRODUCTION
In Europe the minimized transgluteal (TG) and anterolateral (AL) approaches are increasingly preferred in hip arthroplasty (THA).
METHOD
The present investigation determined which of these approaches causes the least muscle trauma. Forty patients who received a THA were enrolled in this prospective randomized study. Muscle trauma was quantified by perioperatively measuring the serum concentration of skeletal troponin I (sTnI). The Harris hip score (HHS) was determined before and 12 months after surgery.
RESULTS
It increased significantly in all patients without being different between the groups (AL, 48.2→83.6; TG, 50.8→85.9). Patients in the TG group had a higher sTnI than those in the AL group 24 h postoperatively (21.6 vs. 10.9 nmol/ml, p = 0.022). The AL approach results in a reduced muscle traumatization compared with the TG approach, without this being revealed by the HHS.
简介
在欧洲，髋关节置换术（THA）中越来越倾向于采用微创经臀肌间隙（TG）和前外侧（AL）入路。
方法
本研究旨在确定这两种入路中哪一种造成的肌肉创伤最小。本前瞻性随机研究纳入了 40 名接受 THA 的患者。通过围手术期测量血清骨骼肌肌钙蛋白 I（sTnI）的浓度来量化肌肉创伤。术前和术后 12 个月分别测定 Harris 髋关节评分（HHS）。
结果
所有患者的 HHS 均显著增加，且两组之间无差异（AL 组：48.2→83.6；TG 组：50.8→85.9）。术后 24 小时，TG 组患者的 sTnI 高于 AL 组（21.6 比 10.9 nmol/ml，p = 0.022）。与 TG 入路相比，AL 入路可减少肌肉创伤，但 HHS 并未显示出这一点。
