- 放射学 放射学是指放射学
背景情况:
- 斯卡法酸盐不稳定性对放射性手腕和手腕中间关节运动的影响尚不清楚.
- 这种知识差距影响了退行变化的预测和救援程序的选择.
研究的目的:
- 为了研究和比较健康手腕和手腕中关节之间的运动分布,而不是那些有脚不稳定的手腕.
- 识别可能预测骨关节炎的动力学差异,并指导治疗决策.
主要方法:
- 动态计算机断层扫描 (CT) 用于评估19个健康的和19个不稳定的手腕的手腕动态.
- 运动被捕获在手腕延伸-曲和骨-辐射偏差期间.
- 计算了脊椎骨和月球骨的放射性手腕和手腕中间动力学.
主要成果:

Bones of the Upper Limb: Humerus
11.3K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Bones of the Upper Limb: Ulna
8.9K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius
9.0K
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
973
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...
