概括

在0.8%的初级无水泥全关节置换术 (THA) 中发生了周围假肢骨骨折. 识别高级年龄和低BMI等风险因素可以帮助减少未来的并发症.

科学领域:

整形外科手术整形外科手术
生物材料科学生物材料科学
放射学放射学是指放射学

背景情况:

周围假肢骨骨折是初级全关节整形术 (THA) 的并发症,使用无水泥组件.
骨折可以从隐性到严重的范围,影响患者的结果.

研究的目的:

为了评估在初级无THA.之后的外科手术期间的外围假肢骨骨折率.
为了确定与这些骨折相关的患者特异性风险因素.

主要方法:

分析了7,016个初级THAs,使用无水泥,酸涂层,模块化acetabular组件.
对外科手术期间的X光片和CT扫描进行审查,并对测量进行基于AI的分析.
对患有骨骨折和没有骨折的患者进行比较,以确定风险因素.

主要成果:

整体骨折率为0.8% (56/7,016),其中71.4%是小的和非手术性的.
在0.2% (16/7,016) 的病例中,需要修订THA.
确定的危险因素包括小的骨部件大小,低的BMI,晚年,女性性别和特定的放射性参数 (低侧面CE角度,高挤出指数,高的夏普和托尼斯角度).

结论:

很大一部分周围假肢骨架骨折是轻微的,不需要修复手术.
特定于患者的因素,包括晚年,女性性别,低BMI和部发育不良,与骨折风险增加有关.
了解这些风险因素可以帮助预防未来的并发症.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
