The extensor carpi radialis brevis is the most commonly affected muscle in lateral epicondylitis (LE), along with other extensor carpal muscles. [15] Due to its unique origin, the ECRB tendon is prone to abrasion during elbow movements, leading to repetitive microtrauma.
The common flexor tendon is a tendon that attaches to the medial epicondyle of the humerus (lower part of the bone of the upper arm that is near the elbow joint). It serves as the upper attachment point for the superficial muscles of the front of the forearm: Flexor carpi ulnaris [1] Palmaris longus; Flexor carpi radialis; Pronator teres
Technique for transferring the m. extensor carpi radialis longus: the m. extensor carpi radialis longus tendon is divided at its insertion on the second metacarpal. The muscle is separated, and freed entirely from the surrounding tissues. The m. extensor carpi radialis longus tendon is strongly attached to the planned tendon under maximum tension.
Carpal tunnel as seen on MRI. The carpal bones that make up the wrist form an arch which is convex on the dorsal side of the hand and concave on the palmar side. The groove on the palmar side, the sulcus carpi, is covered by the flexor retinaculum, a rigid band of fibrous tissue, thus forming the carpal tunnel.
During trapeziectomy with TI, a longitudinal strip of the palmaris longus tendon is collected. [31] If this tendon is absent (which is the case in 13% of the population), half of the flexor carpi radialis tendon (FCR) can be used. The tendon is then formed into a circular shape and placed in the gap, where it is stabilized by sutures. [12]
The tendon of extensor carpi radialis brevis is usually the most major tendon to which the other tendons merge. [2] Function. The common extensor tendon is the major ...
Surgical debridement of the affected tendons, usually the extensor carpi radialis brevis (ECRB) in lateral epicondylitis, and decortication of the lateral epicondyle [6] Surgical debridement of the flexor pronator group that attaches to the medial epicondyle could be indicated after failure of conservative treatment of medial epicondylitis. [7]
The medial border (ulnar side) of the snuffbox is the tendon of the extensor pollicis longus; The lateral border (radial side) is a pair of parallel and intimate tendons, of the extensor pollicis brevis and the abductor pollicis longus. [2] (Accordingly, the anatomical snuffbox is most visible, having a more pronounced concavity, during thumb ...
