Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.5K
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...

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

    本综述探讨了当前在带不稳定性治疗中的争议. 建议包括考虑重度发育不良症的三叶囊整形以及MPFL重建期间结骨切除的特殊标准.

    科学领域:

    • 整形外科手术 整形外科手术
    • 运动医学 运动医学
    • 生物力学 生物力学

    背景情况:

    • 经常出现的皮带不稳定性显著影响患者的生活质量和功能.
    • 最近的研究挑战了骨不稳定的传统治疗原则.
    • 本次审查重点关注三个关键领域:小腿结核-喉沟距离,小腿结核骨切除术与MPFL重建,以及中侧形稳定器重建.

    研究的目的:

    • 审查当前的概念和争议在带不稳定性治疗.
    • 评估结骨切除术 (TTO) 结合中侧骨关节 (MPFL) 重建的适用情况.
    • 讨论不同中间骨稳定剂的作用.

    主要方法:

    • 文献综述近期关于骨不稳定性的研究.
    • 对影响结节-喉沟 (TT-TG) 距离的因素的分析.
    • 评估外科手术技术,包括三整形,TTO和MPFL重建.

    主要成果:

    • 尽管存在风险,但对于Dejour D trochlear发育不良症,可以考虑进行喉膜整形手术.
    • 与MPFL重建相结合的TTO改善了误导病例 (TT-TG 18-20 mm) 的结果.
    • 孤立的MPFL重建可能足以满足一些没有失效的患者 (TT-TG高达25毫米).

    结论:

    • 虽然MPFL重建有强有力的支持数据,但替代技术,如中间四头肌股带和混合方法显示出有前途.
    • 在决定手术方法时,外科医生应仔细考虑患者特定的因素和成像.
    • 需要进一步的研究,以充分阐明新的稳定技术的长期疗效.
