In birds, where the arm is somewhat rotated compared to other tetrapods, it is termed dorsal epicondyle of the humerus. In comparative anatomy, the term ectepicondyle is sometimes used. [2] A common injury associated with the lateral epicondyle of the humerus is lateral epicondylitis also known as tennis elbow. Repetitive overuse of the forearm ...
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus. The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament. [1]
Lateral elbow pain can be caused by various pathologies of the common extensor tendon. [3] Overuse injuries can lead to inflammation. [4] [5] Tennis elbow is a common issue with the common extensor tendon. [6] [4] [7]
The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm ; [ 2 ] more specifically between the humerus in the upper arm and the radius and ulna in the ...
Tear drop sign - Tear drop sign is seen on a normal radiograph, but is disturbed in supracondylar fracture. [8] Anterior humeral line - It is a line drawn down along the front of the humerus on the lateral view and it should pass through the middle third of the capitulum of the humerus. [9]
A humerus fracture is a break of the humerus bone in the upper arm. [1] Symptoms may include pain, swelling, and bruising. [1] There may be a decreased ability to move the arm and the person may present holding their elbow. [2] Complications may include injury to an artery or nerve, and compartment syndrome. [2]
The condyle of humerus is the distal end of the humerus. It is made up of the capitulum and the trochlea. [1] References This page was last edited on 5 ...
The brachioradialis is a superficial, fusiform muscle on the lateral side of the forearm. It originates proximally on the lateral supracondylar ridge of the humerus. It inserts distally on the radius, at the base of its styloid process. [3] Near the elbow, it forms the lateral limit of the cubital fossa, or elbow pit. [4]
