概括
部发育性发育不良 (DDH) 的近腰形态与健康的部不同,前腿部形在DDH患者中更为常见. 为了防止并发症,外科医生应在骨切除术 (PAO) 期间考虑这一点.
科学领域:
- 骨科手术
- 放射学
- 部发育不良的研究
背景情况:
- 围骨切除 (PAO) 需要了解靠近大腿骨的形态,以避免二次大腿骨撞击.
- 部发育性发育不良 (DDH) 在靠近股骨的解剖学中存在独特的挑战.
研究的目的:
- 在DDH患者中描述近腰骨形态.
- 为了确定DDH和健康的部之间的α角和形差异.
主要方法:
- 对57名DDH患者 (77名部) 和30名对照患者 (30名部) 的回顾性分析.
- 三维CT成像和冠状切片分析以测量七个位置的α角.
- 凸轮变形的定义为≥60°的α角.
主要成果:
- 与对照组相比,DDH组在前面的角度显示出更大的α角.
- DDH组表现出更高的凸轮形,位于更前部 (2:00-3:00).
- 在DDH组中最大的α角与较高的acetabular覆盖率相关.
结论:
- 在DDH患者中,靠近大腿骨的形态,特别是前变形,是不同的.
- 在PAO期间,外科医生必须考虑乙体版本,并避免DDH患者的形.

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...

Changes in the Appendicular Skeleton with Age
2.2K
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...
