概括
整部关节整形术 (THA) 改善关节膝关节 (HKA) 在部发育性形 (DDH) 患者的对齐. 然而,THA后的全球偏移 (GO) 减少可能会加剧膝关节形,突出显示GO恢复的重要性.
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
背景情况:
- 关于全关节整形术 (THA) 对形膝盖形症在部发育性形症 (DDH) 患者的影响存在相互矛盾的证据.
- 了解影响THA后膝盖形进展的因素对于患者的治疗结果至关重要.
研究的目的:
- 确定导致DDH患者THA后形膝关节形变形恶化的因素.
- 分析影响THA后膝关节对齐变化的放射性参数.
主要方法:
- 对51名DDH患者 (Crowe型IV) 进行了回顾性病例控制研究,这些患者接受了初级THA.
- 在THA之前和之后测量多个放射角度 (aLDFA,mLDFA,MPTA,HKA,TFA,JLCA,TJLA) 和偏移 (FO,AO,GO).
- 病例组) 和没有病例组 (对照组) 之间的放射性参数的比较.
主要成果:
- 两组都显示了THA后的HKA改善.
- 病例组具有较小的THA前HKA和较大的THA前乙基体偏移 (AO) 和全球偏移 (GO).
- 在THA后,GO在两组都下降,关节直线角 (TJLA) 在病例组显著增加.
结论:
- 在DDH患者中,THA可以改善HKA.
- 在THA后,全球偏移 (GO) 的减少可能会导致关节直线角度 (TJLA) 的增加,这表明形变形的伪进展.
- 在THA期间恢复全球偏移 (GO) 可能可以缓解恶化的膝关节形.

Knee Joint
1.6K
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
1.5K
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...

Bones of the Lower Limb: Femur and Patella
2.3K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Development of the Limb Synovial Joints
1.3K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
