概括
斯卡夫特拉皮齐特拉皮齐性骨关节炎 (STT-OA) 的严重程度与背部间隔段不稳定性 (DISI) 有关. 先进的STT-OA与较高的DISI发病率相关,其特征是特定的手角变化.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 手和手腕 生物力学 手和手腕 生物力学
背景情况:
- 斯卡波特拉皮齐特拉皮齐性骨关节炎 (STT-OA) 是一种影响手腕的常见疾病.
- STT-OA严重程度与手腕不稳定性之间的关系,特别是背部间隔段不稳定性 (DISI),需要进一步调查.
- 了解这些关联可以帮助诊断和管理手腕不稳定.
研究的目的:
- 分析有不同程度的STT-OA的手腕手腕的放射性手腕指数.
- 调查STT-OA严重程度与DISI发生之间的关联.
- 为了确定与STT-OA相关的手腕不稳定的放射特征.
主要方法:
- 在135个带有STT-OA的手腕中对手腕指数的回顾性分析 (克罗斯比分类等级2和3).
- 测量辐射 (RL),辐射 (RS),斜 (SL) 角度,月球头角 (LC) 角度和SL距离.
- STT-OA等级之间的手腕指数和DISI发生率的比较;对其他关节OA的评估和对DISI手腕的相关性分析.
主要成果:
- 与2级相比,3级STT-OA手腕的RL和RS角度较小,LC角度较大.
- 在5%的2级和60%的3级STT-OA手腕中存在DISI.
- 没有观察到SL角度>70°,SL距离扩大或RS关节OA;DISI手腕显示负RL-LC和正RL-RS相关性.
结论:
- 在STT-OA严重程度和DISI发生之间存在关联.
- 在STT-OA中,手腕不稳定性呈现出独特的特征:扩展的脚,正常的SL角度,以及没有RS-OA.
- 这些发现有助于描述STT-OA的手腕不稳定模式.

Bones of the Upper Limb: Radius
4.5K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
381
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
