Traditional total hip arthroplasty (THA) using the direct anterior approach (DAA) requires a hip extension. This study aimed to compare the clinical outcomes of patients undergoing THA with DAA using either the no hip extension (NHE) or the traditional hip extension (THE) strategy.
A retrospective analysis of demographics, clinical and radiological outcomes, and occurrence of complications was performed using data from 123 patients treated between January 2020 and November 2021. The patients were categorised into two groups: NHE (84 patients) and THE (39 patients).
The NHE group exhibited shorter operative time and had more male participants with higher ages. Comparable outcomes were observed in the visual analogue scale, Harris Hip, and Oxford Hip scores at the final follow-up. Furthermore, complications were observed in the NHE and THE groups, including two and one greater trochanteric fractures and three and one transfusions, respectively.
Compared to the THE, employing the NHE strategy during THA with DAA in elderly and young female patients resulted in comparable clinical outcomes with several advantages, such as favourable surgical time. The NHE method also exhibited good safety and effectiveness. Therefore, the NHE strategy may be a favourable option for elderly and young female patients.
传统的直接前入路（DAA）全髋关节置换术（THA）需要髋关节伸展。本研究旨在比较采用无髋关节伸展（NHE）或传统髋关节伸展（THE）策略的 DAA 下 THA 患者的临床结果。
回顾性分析了 2020 年 1 月至 2021 年 11 月期间接受治疗的 123 名患者的人口统计学、临床和影像学结果以及并发症发生情况的数据。患者分为两组：NHE（84 例）和 THE（39 例）。
NHE 组的手术时间更短，男性参与者更多，年龄更高。在最终随访时，视觉模拟评分、Harris 髋关节评分和牛津髋关节评分的结果相似。此外，NHE 和 THE 组均观察到并发症，包括 2 例和 1 例大转子骨折，以及 3 例和 1 例输血。
与 THE 相比，在老年和年轻女性患者的 DAA 下 THA 中采用 NHE 策略可获得相似的临床结果，且具有手术时间更短等优势。NHE 法也具有良好的安全性和有效性。因此，NHE 策略可能是老年和年轻女性患者的有利选择。
