概括
超骨切除术 (SMOT) 有效地纠正脚关节炎,影响关节下部的整齐. 手术后,下关节的移动有助于保持后脚的中立性,与手术前的脚和脚偏移相关.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械分析 生物机械分析
- 放射性成像成像 放射性成像成像
背景情况:
- 已知下关节在下关节形变形中的补偿作用,但在上骨切除术 (SMOT) 后,其纠正后的行为仍然不清楚.
- 超骨切除术 (SMOT) 是一种已被公认的治疗关节关节炎的方法.
- 了解SMOT后的亚关节对齐变化对于外科手术结果至关重要.
研究的目的:
- 在SMOT之前和之后评估关节下部关节对齐在患有关节关节炎的患者中.
- 为了识别影响SMOT后下关节对齐的因素.
主要方法:
- 对31名高库拉2期,3a期和3b期关节关节炎患者进行了回顾性审查,这些患者接受了SMOT治疗.
- 使用负载式放射和负载式计算机断层扫描 (WBCT) 评估部和脚关节的对齐.
主要成果:
- 观察到足部和脚偏移 (FAO),关节表面角 (TAS),关节表面角 (TTS) 和关节下垂直角 (SVA) 的显著纠正 (P<0.05).
- 在SMOT (P<0.001) 后发生了次侧倾角 (SIA) 变化 (P<0.001).
- 下关节转移 (ΔSIA) 的幅度与手术前的FAO相反相关 (P<0.001,r=-0.621) ,并且在手术前更严重的后脚形时更大.
结论:
- 在SMOT之后的下关节转移有助于保持中立的后脚位置.
- 手术前的脚和脚偏移是SMOT后部关节移位程度的重要预测因素.
- 后脚变形的程度会影响术后的底关节反应.

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...

Knee Joint

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...
