The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
The tendons to the second, third, and fourth toes are each joined, opposite the metatarsophalangeal articulations, on the lateral side by a tendon of the extensor digitorum brevis. The tendons are inserted in the following manner: each receives a fibrous expansion from the interossei and lumbricals, and then spreads out into a broad aponeurosis ...
Specifically, these extensor muscles include the anconeus muscle, the supinator, extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris. [1] In birds, where the arm is somewhat rotated compared to other tetrapods, it is termed dorsal epicondyle of the humerus.
The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] brachioradialis; extensor carpi radialis brevis; extensor carpi radialis longus; It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
Occasionally the first tendon is connected to the second by a thin transverse band. Collectively, these are known as the sagittal bands; they serve to maintain the central alignment of the extensor tendons over the metacarpal head, [3] thus increasing the available leverage. Injuries (such as by an external flexion force during active extension ...
Juncturae tendinum are narrow bands of connective tissues that extend between the tendons of the extensor digitorum communis and the extensor digiti minimi. [1] [2] It is classified into three distinct types (Type 1, 2 and 3) depending on morphology. [3] Type 1: This is a thin and filamentous juncturae tendinum. Its shape can either be square ...
A graft of the extensor retinaculum was shown to be useful in treating boxer's knuckle when direct repair of the damaged capsule is not possible. [6] Because of their similarities in histological structure, studies also show the extensor retinaculum to be a reasonable biological replacement for reconstruction of a deficient annular pulley. [6]
The extensor tendons are connected to the second by a thin transverse band, known as the juncturae tendinum; they serve to maintain the central alignment of the extensor tendons over the metacarpal head, [5] thus increasing the available leverage. Injuries (such as by an external flexion force during active extension) may allow the tendon to ...
