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 posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
The Milch classification is a system of categorizing single column (AO type B) distal humerus fractures based on the pattern of epicondyle involvement. It is distinct from the Jupiter classification which is used for bicolumnar distal humerus fractures.
The lateral supracondylar ridge is a prominent, rough margin on the lower part of the lateral border of the humerus. It presents an anterior lip for the origin of forearm extensors, including the brachioradialis muscle above, and the extensor carpi radialis longus muscle below. [ 1 ]
The cause of a humerus fracture is usually physical trauma such as a fall. [1] Other causes include conditions such as cancer in the bone. [2] Types include proximal humeral fractures, humeral shaft fractures, and distal humeral fractures. [1] [2] Diagnosis is generally confirmed by X-rays. [2]
An epicondyle (/ ɛ p ɪ ˈ k ɒ n d aɪ l /) is a rounded eminence on a bone that lies upon a condyle (epi-, "upon" + condyle, from a root meaning "knuckle" or "rounded articular area"). There are various epicondyles in the human skeleton, each named by its anatomic site. They include the following:
A supracondylar humerus fracture is a fracture of the distal humerus just above the elbow joint. The fracture is usually transverse or oblique and above the medial and lateral condyles and epicondyles. This fracture pattern is relatively rare in adults, but is the most common type of elbow fracture in children. [1]
