概括
添加横向视网膜释放 (LRR) 到中侧骨关节带 (MPFL) 重建不会改变骨高度. 无论是单独的MPFL重建还是与LRR一起,都显著降低了骨高度,通过Caton-Deschamps指数测量.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 放射学 放射学是一门学科.
背景情况:
- 经常发生的带脱位 (RPD) 往往需要手术干预.
- 中部骨带 (MPFL) 重建是RPD的常见治疗方法.
- 同时横向视网膜释放 (LRR) 在MPFL重建中关于骨高度的作用尚未完全理解.
研究的目的:
- 评估MPFL重建与LRR或没有LRR对RPD患者骨高度的影响.
- 为了测试LRR与单独的MPFL重建相比,LRR不会显著改变皮带高度的假设.
主要方法:
- 预期的,单盲随机对照试验 (II级证据).
- 107名年龄在18-45岁的RPD患者被随机分为两组:单独的MPFL重建或MPFL重建与LRR.
- 用Caton-Deschamps指数 (CDI) 在手术后至少1年的侧面放射图上评估了骨高度.
主要成果:
- 手术前的CDI在两组之间是相似的 (LRR: 1.32 ± 0.168;孤立的MPFL: 1.29 ± 0.163).
- 在手术后的CDI显示,在两组患者中,皮带高度显著下降 (1.1 ± 0.133在LRR组,1.1 ± 0.166在孤立的MPFL组).
- 在MPFL重建与LRR组和孤立的MPFL重建组之间,没有观察到术后骨高度的显著差异.
结论:
- 侧侧视网膜释放 (LRR) 在添加到中侧骨关节带 (MPFL) 重建时不会显著影响带高度.
- 随着或没有LRR的MPFL重建,导致皮带高度显著降低 (平均CDI下降0.2).

01:40Bone 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.
01:27Fractures: Bone Repair
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 procedure...

01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
