概括
与标准轴承 (SB) 相比,模块化双流动性 (modDM) 可能会降低初级关节整形术 (THA) 中的脱位风险. 然而,特定的假肢内位需要谨慎使用modDM植入物.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料工程 生物材料工程
- 医疗器械技术 医疗器械技术
背景情况:
- 双流动性 (DM) 是为了减少关节整形术 (THA) 脱位风险而建立的.
- 模块化DM (modDM) 允许DM与标准的无水泥acetabular外进行关节.
- 对于初级THA中modDM的临床数据有限,人们越来越担心植入物并发症.
研究的目的:
- 在初级THA中比较modDM和标准轴承 (SB) 结构之间的失位率.
- 评估与modDM相比SB相关的植入物存活率和并发症率.
- 评估modDM在降低初级THA中脱位风险方面的有效性.
主要方法:
- 一个回顾性比较多中心研究,涉及262个主要的THA (2017-2019).
- 腰部用相同的无水泥形杯子用SB (129) 或modDM (133) 进行治疗.
- 收集的数据包括位,并发症,修订和植入物存活率.
主要成果:
- 在平均2.5年的随访中,SB的脱位率为3.1%,modDM的1.5% (p=0.44).
- 在2个modDM病例中发生了假肢内位.
- 由于脱而导致的四年植入物存活率为SB的95.2%,modDM的95.9% (p=0.50).
结论:
- 在初级全关节整形术中,模块化双移动 (modDM) 可能与标准轴承 (SB) 相比,提供较低的脱位率.
- modDM甚至可以对接受初级THA的高风险患者有益.
- 建议谨慎使用,因为modDM植入物可能会产生特定的假肢内位.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Knee Joint
1.9K
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...

Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
