概括
在后部稳定的全膝关节整形术中,囊释放显著增加了延伸间隙. 这种手术技术不会显著影响曲间隙,有助于间隙平衡.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
- 关节塑造研究 关节塑造研究
背景情况:
- 后部稳定全膝关节整形手术 (PS-TKA) 往往会经历下降的延伸间隙后股骨试验放置,导致不平衡.
- 众所周知,囊释放在介质隙周围会扩大延伸间隙,但其对曲间隙的影响尚不清楚.
研究的目的:
- 评估囊释放在介质间口周围对PS-TKA延伸和曲间隙的影响.
- 为了确定囊释放是否可以帮助平衡PS-TKA手术期间的关节间隙.
主要方法:
- 一项涉及100名接受PS-TKA的患者的研究.
- 在手术期间进行囊释放,以解决曲收缩和平衡关节间隙.
- 在释放前和释放后测量了差距和倾斜角度,使用 FuZionTM 张力器,在释放前和释放后使用 40 磅分心力.
主要成果:
- 在囊释放后,平均延伸间隙从10.0毫米显著增加到12.5毫米 (P < 0.001).
- 平均曲间隙显示了微不足道的变化,从14.1毫米变为14.2毫米 (P = 0.58).
- 延伸的中间部件间隙显著改善,延伸和屈曲间隙之间的差异减少.
结论:
- 囊释放在介质间口周围有效地扩大PS-TKA的延伸间隙.
- 这种技术对曲元件间隙的影响微不足道,这表明它在管理延伸间隙缺口方面具有实用性.

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...

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 group...

Ankle Joint
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...
