Functional Classification of Joints

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

1.8K
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...

概括

这项研究表明,在修复整部关节整形术 (THA) 期间将双流动性 (DM) 杯子结到非化骨外中,可以提供良好的植入物存活和固定,尽管位仍然是一个风险.

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
  • 关节塑造研究 关节塑造研究

背景情况:

  • 脱位是修复全关节整形术 (THA) 的主要并发症.
  • 双流动性 (DM) 轴承降低了脱位风险,但在非水泥的情况下,选择是有限的.
  • 一种技术涉及将单块DM杯结到一个未化的acetabular shell中.

研究的目的:

  • 为了评估植入物存活率,并发症,以及在修改THA过程中将DM杯凝固到非凝固的acetabular外中的放射性结果.
  • 在复杂的案例中评估这种构造的可行性和有效性.

主要方法:

  • 在65个部 (64名患者) 的回顾性审查中,在2018-2020年期间使用这种技术进行了THA修订.
  • DM杯被凝固到非凝固的外中 (新的或保留的).
  • 卡普兰-梅尔生存分析和放射性评估进行了平均2年后续.

主要成果:

  • 无无菌性DM修订和脱位的两年生存率为92%.
  • 发生了9次修订:3次是感染,3次是无菌松动,2次是脱位,1次是结构故障.
  • 发生了五次手术后脱位,主要发生在先前不稳定或吸收器缺陷的患者中.

结论:

  • 将DM杯结成非的外是修改THA的一个可行的选择,最大限度地提高头部尺寸和优化组件位置.
  • 这种技术证明了良好的植入物固定,在接口上只有一次故障.
  • 虽然位风险降低了,但并没有消除,特别是在高风险患者中.
