概括
盘状侧半月体 (DLM) 在中侧半月体后部根撕裂 (MMPRT) 患者中更常见. 无论DLM存在,MMPRT维修结果都是有利的.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 膝盖外科手术 膝盖外科手术
背景情况:
- 中间阴茎后部根撕裂 (MMPRT) 显著影响膝盖生物力学,并可以加速骨关节炎.
- 早期诊断MMPRT至关重要,需要确定相关的风险因素.
- 盘状侧半月体 (DLM) 是一种常见的先天性异常,但其与MMPRT的关联仍然未被探索.
研究的目的:
- 为了研究中间半月体后部根撕裂 (MMPRT) 和圆盘侧面半月体 (DLM) 之间的关系.
- 为了确定DLM是否是MMPRT的风险因素或相关条件.
主要方法:
- 一项回顾性队列研究将58个膝盖与MMPRT进行比较,与36个膝盖进行了其他中间阴茎损伤,并与年龄和性别相匹配.
- 冠状核磁共振扫描仪用于横侧半月体 (LM) 的形态分析,通过LM比率> 0.20.20来定义DLM.
- 比较了LM宽度,LM比率和DLM患病率;在MMPRT分组中,在手术前和手术后评估了临床结果,包括DLM.
主要成果:
- 与对照组相比,MMPRT组表现出明显更大的LM宽度和LM比率.
- 在MMPRT组 (29.3%) 中,DLM的患病率明显高于其他中间半月膜损伤组 (8.3%).
- 在有或没有DLM的MMPRT小组之间,没有发现临床结果的显著差异,两组都显示出明显的术后改善.
结论:
- 盘状侧半月体 (DLM) 在膝盖中明显更为普遍,中间半月体后部根裂 (MMPRT).
- 关节镜拔出修复给MMPRT带来了有利的临床结果,无论DLM是否存在.
- DLM可能是MMPRT的相关发现,但似乎不会对手术结果产生负面影响.

01:27Degenerative Disc Disease I: Introduction
29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

01:23Degenerative Disc Disease ll: Pathophysiology
36
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
