概括
患有硬脊椎的患者表现出部机制的改变,包括超延伸的站立部和超屈曲的深坐部. 建议进行深部放射,以确定关节整形术后的脊柱硬和潜在风险.
科学领域:
- 整形外科和生物力学
- 脊椎和部生物力学 脊椎和部生物力学
- 放射学分析 放射学分析
背景情况:
- 由于盆腔硬,关节整形术 (THA) 后,硬的脊柱增加了不稳定的风险.
- 在没有关节炎的脊椎硬患者中了解补偿机制对于手术指导至关重要.
研究的目的:
- 描述部硬或脊椎硬患者的静态和动态补偿力学.
- 为了确定解补偿的最佳脊皮皮膜成像方式.
- 评估脊柱融合长度对补偿力学的影响.
主要方法:
- 展望性,病例对照研究与三个组:控制 (n=52),关节骨关节炎治疗THA (n=52) 和后脊柱融合 (n=52).
- 静态和动态的脊骨参数 (腰部位,骨盆倾斜,骨盆角) 用站立,放松和深坐的X射线图进行测量.
- 分析了合的脊柱段与脊椎骨盆参数之间的相关性.
主要成果:
- 脊椎组与对照组和部组相比,表现出更高的站立骨盆-股骨角和骨盆倾斜.
- 脊椎组显著减少腰部曲,在站立和深坐姿势之间有更大的骨盆倾斜变化.
- 脊椎组的深部部曲更大;对深部曲的评估有效地解开了补偿机制.
结论:
- 脊柱硬的患者表现出部和骨盆力学的显著变化,特别是骨盆倾斜的巨大变化.
- 这种骨盆倾斜的变化可能导致亚最佳的骨杯方向,增加THA后撞击或脱位的风险.
- 建议进行深部放射,以更好地识别脊柱硬和相关的补偿机制.

Vertebral Column: Regions and Curvature
5.9K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Structural Joints: Cartilaginous Joints
3.8K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
