概括
在为周围假肢关节感染 (PJI) 进行两阶段修复时,抗生素间隔器的机械并发症很常见,特别是在膝盖修复中. 然而,这些并发症并不妨碍成功的再植入或部件保留.
科学领域:
- 整形外科 整形外科 整形外科
- 传染性疾病 传染性疾病
- 生物材料是一种生物材料.
背景情况:
- 双阶段修复手术是一种常见的治疗周围假肢关节感染 (PJI).
- 带有抗生素的水泥间隔器是此过程中使用的临时设备,存在机械并发症的风险.
- 了解这些并发症对于优化PJI治疗结果至关重要.
研究的目的:
- 在PJI治疗中确定与抗生素间隔剂相关的机械并发症的发生率.
- 确定导致这些机械并发症的风险因素.
- 评估机械间隔器并发症对后续PJI治疗成功的影响.
主要方法:
- 六年来对236名接受PJI抗生素间隔剂的患者进行了回顾性审查.
- 分析医疗记录和X射线图,以确定机械并发症和相关风险因素.
- 使用多变量逻辑回归来评估风险因素和对治疗成功的影响.
主要成果:
- 部间距器的整体机械并发症率为8.5%,膝盖间距器为18.2%.
- 膝盖间距,骨损失和BMI升高是机械并发症的重要危险因素.
- 骨损失和晚年独立预测无法接受第二阶段的再植入.
- 机械间隔器故障并没有独立影响重新植入的成功或部件的保留.
结论:
- 在PJI治疗中,抗生素间隔剂的机械并发症很常见,特别是在膝盖修复和骨损失或高BMI的患者中.
- 尽管发生了这些并发症,但这些并发症似乎不会对成功重新植入或长期保留组件的可能性产生负面影响.
- 对于高风险病例,建议针对性预防策略和患者咨询.

Knee Joint
2.0K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
