Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.1K
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...

Muscles of the Forearm that Move the Hand and Fingers

906
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.0K
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...

科学领域:

  • 整形外科成像 整形外科成像
  • 放射学 放射学是一门学科.
  • 肌肉骨系统 运动器官系统

背景情况:

  • 在手腕MRI上发生的三角纤维软骨复合体 (TFCC) 变化可以在没有症状的情况下发生.
  • 这项研究调查了无症状TFCC变化的患病率.

研究的目的:

  • 为了确定无症状TFCC变化的速度,在接受手腕MRI治疗非侧手腕疼痛的患者中.
  • 为了将这一率与患有侧手腕疼痛的患者进行比较.

主要方法:

  • 对132例手腕MRI病例 (CPT代码73221) 的回顾性审查.
  • 对人口统计,症状,检查,创伤和MRI发现的分析.
  • 主要队列 (非腰椎侧面疼痛) 和对照组 (腰椎侧面疼痛) 的比较.

主要成果:

  • 44%没有腰侧手腕疼痛的患者在MRI上显示异常的TFCC.
  • 异常的TFCC发现与年龄较大有关.
  • 80%的侧手腕疼痛患者在MRI上有异常的TFCC.

结论:

  • 在无症状个体中,MRI上的异常TFCC发现很常见.
  • 与患者症状的临床相关性对于准确诊断至关重要.
  • 患者应被告知,手腕MRI中偶然发现TFCC的可能性很高.
