Total hip arthroplasty (THA) is one of the most widely performed orthopedic surgeries. Techniques for small skin incisions and preservation of muscles and tendons have been developed. However, avoiding skin complications and muscle damage due to forced deployment and surgical manipulation is challenging. This study aimed to investigate whether the use of Alexis Orthopedic Protector (Applied Medical Resources Corp., Rancho Santa Margarita, CA, USA) affects postoperative outcomes.
This was a retrospective cohort study including 118 patients who underwent primary THA by the same surgeon at our single institution between March 2021 and March 2023. Protectors were used alternately for each operation. Fifty-nine patients were in the protector-using group (P group), and 59 were in the nonprotector-using group (N group), with comparisons made between groups. Protectors were placed under the fascia in all patients.
Preoperative blood tests showed no difference in renal and hepatic function between the two groups. No differences in postoperative C-reactive protein (CRP) and creatine kinase (CK) values or in the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (JHEQ) and Numerical Rating Scale (NRS) scores were observed. Postoperative redness was significantly higher in the N group than in the P group (49.2% vs. 7%). The percentage of hypertrophic scars at three months postoperatively was 18.6% in the N group and 7% in the P group. Furthermore, the Japan Scar Workshop Scar Scale (JSS) indicated that hypertrophic scars were significantly worse in the N group than in the P group ( = 0.0012).
Alexis® Orthopedic Protectors can not only provide short-term wound protection but also reduce the rate and degree of hypertrophic scarring.
全髋关节置换术（THA）是最常开展的骨科手术之一。现已开发出小切口皮肤以及保留肌肉和肌腱的技术。然而，避免因强行展开和手术操作导致的皮肤并发症和肌肉损伤具有挑战性。本研究旨在调查使用Alexis骨科保护器（美国加利福尼亚州兰乔圣玛格丽塔市应用医疗资源公司）是否会影响术后结果。
这是一项回顾性队列研究，纳入了2021年3月至2023年3月期间在我们单一机构由同一位外科医生进行初次THA的118例患者。每次手术交替使用保护器。59例患者为使用保护器组（P组），59例为未使用保护器组（N组），对两组进行比较。所有患者均将保护器置于筋膜下。
术前血液检查显示两组的肾功能和肝功能无差异。术后C反应蛋白（CRP）和肌酸激酶（CK）值、日本骨科协会髋关节疾病评估问卷（JHEQ）和数字评定量表（NRS）评分均无差异。N组术后发红明显高于P组（49.2%对7%）。术后三个月时，N组增生性瘢痕的百分比为18.6%，P组为7%。此外，日本瘢痕研讨会瘢痕量表（JSS）表明，N组的增生性瘢痕明显比P组严重（P = 0.0012）。
Alexis®骨科保护器不仅能提供短期伤口保护，还能降低增生性瘢痕的发生率和严重程度。
