概括
患有常见带脱 (HPD) 的儿童表现出明显的解剖学差异,这取决于脱是否发生在延伸或曲方面. 对于有效的手术策略来说,了解骨和三角形形的这些差异是关键.
科学领域:
- 骨科手术
- 儿童整形医学
- 生物医学工程
背景情况:
- 习惯性带脱 (HPD) 在儿童中存在两种主要类型:屈曲脱和延伸脱.
- 这些HDP亚型的潜在致病机制和独特的解剖特征仍然不完全理解.
研究的目的:
- 在儿科患者中研究和比较HDP与延伸脱和HDP与曲脱之间的解剖差异.
- 确定两种HDP亚型的特定解剖学参数.
主要方法:
- 在2016年5月至2023年8月期间接受HDP手术的儿科患者的回顾性分析.
- 根据"J标志"划分成延伸和曲组.
- 对CT衍生的解剖学参数进行比较分析:形形,三形形,形骨关节对齐,膝关节扭形.
主要成果:
- 延伸组显示出显著更高的维伯格指数,侧角,PT/FT比率和卡顿-德尚指数.
- 曲组在伸展过程中表现出较大的骨侧面化,骨倾斜,侧面骨角,以及较小的侧面三角倾斜.
- 与延伸组 (51%) 相比,在曲组 (100%) 观察到更高的Dejour类型C和D大腿.
- 在手术前症状的持续时间在延长组显著更长.
结论:
- 在延伸方面,HDP与骨高和更严重的骨发育不良有关.
- 在曲过程中,HDP的特征在于延伸过程中更倾斜和横向的骨,以及更不稳定的股骨三角质.
- 这些解剖学区别对于理解脱位机制和指导儿科HDP手术治疗决策至关重要.

Bones of the Lower Limb: Femur and Patella
2.9K
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
2.2K
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...

Anatomical Movements
11.5K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
