概括

周围骨切除术 (PAO) 持续增加骨盆发生率和侧面中心-边缘角度. 脊柱不移的患者或接受双边PAO的患者在手术后经历了额外的脊骨皮层对齐变化.

科学领域:

整形外科手术整形外科手术
脊柱生物力学脊柱生物力学
骨盆的重建骨盆的重建

背景情况:

周围骨切除术 (PAO) 是一种治疗关节发育不良的外科手术.
有限的数据存在于PAO对腰脊骨皮层对齐的影响.
准确评估脊椎骨盆变化对于手术规划和结果至关重要.

研究的目的:

通过使用EOSX射线图来评估PAO后脊骨皮层对齐的持续变化.
为了比较单边和双边PAO之间的这些变化.
为了研究脊柱移动性和手术前的骨盆倾斜对术后对齐的影响.

主要方法:

未来收集55名PAO患者的EOS放射 (站着和坐着) 图像.
在手术前和后 (平均15个月) 测量骨盆发病率,骨盆倾斜率,交叉骨斜率,腰椎位症和其他参数.
基于单边/双边PAO,脊柱移动性和手术前骨盆倾斜的子组分析.

主要成果:

PAO显著增加了站立和坐着的侧面中心边缘角度和站立的骨盆发生率.
双边发育不良症患者的双边PAO显示骨盆发病率增加,阴部交融到神经结指数减少.
手术前脊柱不移的患者在PAO后经历了显著的脊骨骨对齐变化.

结论:

PAO导致盆腔发病率增加,可能是由于前部中心翻译.
脊皮膜参数变化在PAO后是最小的,除了双边病例.
手术前的脊柱不运动可能使患者在PAO后更容易发生脊椎骨盆对齐变化,需要进一步调查.

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Changes in the Appendicular Skeleton with Age

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...
