概括
建议使用六足脚固定器过度纠正骨变形,以保持对齐. 目标是对机械轴角 (MAA) 进行5°的曲过度校正,以及对机械轴偏差 (MAD) 进行7-9毫米的中间过度校正,以防止由于重塑而导致的校正损失.
科学领域:
- 整形外科手术 整形外科手术
- 儿科整形医生 儿科整形医生
- 肢体变形纠正器 肢体变形纠正器
背景情况:
- 青少年的小腿变形会导致肢体出现显著的不对齐.
- 六足动物的圆形固定器用于纠正复杂的部形.
- 纠正后的改造可能会导致失去已实现的对齐.
研究的目的:
- 用六足足固定器对骨变形纠正后评估潜在的纠正损失.
- 为了确定失去了纠正是否会影响临床结果.
- 建立最佳的校正目标,以减轻长期调整变化.
主要方法:
- 对18名青少年患者进行了回顾性研究,这些患者患有骨变形.
- 使用Hexapod外部固定器进行校正.
- 肢体形 - 脊椎病研究会 (LD-SRS) 评分和放射性参数 (机械轴偏差 [MAD],机械轴角度 [MAA]) 在手术前,手术后和最终随访时的评估.
主要成果:
- 在平均18.7个月的随访后,LD-SRS得分 (3.4至4.6) 和放射性对齐显著改善.
- 机械轴角 (MAA) 从25.1° varus改进到1.7° valgus后校正,最后的后续检查为2.4° varus.
- 机械轴偏差 (MAD) 从正后的87.4毫米中位改善到7.3毫米中位,最后的随访是6.1毫米横向.
结论:
- 在六足动物固定器纠正骨瓦拉后进行重塑,可能会导致一些纠正损失.
- 建议进行过度校正,以实现长期稳定的四肢对齐.
- 建议过度纠正MAA5° () 和MAD7-9mm (中位) 以抵消重塑效应.

Fractures: Bone Repair
3.7K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bone Remodeling
38.5K
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.
