概括
"跳跃标志"在复发型带脱位 (RPD) 中与明显的下肢旋转和骨异常相关,类似于高级J标志. 这有助于为RPD治疗进行手术规划.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械分析分析
- 医学成像医学成像
背景情况:
- 经常发生的带脱位 (RPD) 通常与底层下肢不整齐有关.
- 识别特定的形跟踪标志对于理解和管理RPD至关重要.
- "J标志"是已知的带不良跟踪的指标,但它与特定骨异常的相关性需要进一步阐明.
研究的目的:
- 引入和验证一种新的标志,用于RPD患者的带不良追踪.
- 为了比较下肢旋转和骨结构异常在不同的骨跟踪标志之间,包括新标志和J标志.
- 评估拟议标志在识别相关异常方面的临床实用性.
主要方法:
- 对279名因RPD接受初次手术的患者 (平均年龄22岁) 的回顾性分析.
- 患者被按J标志级 (低,中等,高) 和皮带运动 ("跳跃"与"滑翔") 分类.
- 双边关节膝关节CT扫描用于测量旋转和骨参数;进行了可靠性分析.
主要成果:
- "跳跃标志"在37%的患者中被观察到,并且在高级J标志组 (82%) 中明显更频繁.
- 与"滑动"组相比,具有"跳跃标志"的患者表现出较高的股骨前转,过度的膝盖扭动,三角形形,上三角,增加的小腿结节-三角沟距离,更平坦的侧三角形倾斜和过度的角.
- 在"跳跃符号"和高级J符号之间没有发现显著的形态差异.
结论:
- "跳跃标志"在复发型带脱位 (RPD) 中与下肢旋转和骨结构异常有很强的联系.
- 这些异常与在高等级的J标志中观察到的异常高度一致.
- "跳跃标志"可以帮助外科医生和患者做出关于进一步诊断成像和手术干预的明智决定,例如骨切除术,用于RPD管理.

Bones of the Lower Limb: Femur and Patella
2.2K
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
1.5K
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...

Structural Joints: Cartilaginous Joints
2.1K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Ankle Joint
1.4K
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...

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.

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.
