Extensor carpi radialis brevis. An anatomical analysis of its origin.
We studied the origin of extensor carpi radialis brevis using 40 fresh frozen human cadaver specimens. Ten were stained with haematoxylin and eosin and trichrome which showed the collagenous structure of the extensor tendons at their origin. Gross anatomical observation showed that there was no definitive separation between brevis and communis at the osseotendinous junction. The histological fi...
متن کاملVariant insertion of extensor carpi radialis longus in a South Indian cadaver
The extensor carpi radialis longus (ECRL) muscle originates from the distal third of the lateral supracondylar ridge of the humerus, front of lateral intermuscular septum and from the lateral epicondyle of humerus. The tendon of ECRL along with extensor carpi radialis brevis (ECRB) passes through the second compartment of extensor retinaculum and inserts into the base of second metacarpal bone ...

متن کاملAnatomical Variation of Radial Wrist Extensor Muscles: A Study in Cadavers
OBJECTIVE The tendons of the extensor carpi radialis longus and brevis muscles are quite useful in tendon transfer, such as in correction of finger clawing and restoration of thumb opposition. Knowledge of additional radial wrist extensor muscle bellies with independent tendons is useful in the above-mentioned surgical procedures. METHODS The skin, subcutaneous tissue, and antebrachial fascia...
متن کاملMoment arm and force-generating capacity of the extensor carpi ulnaris after transfer to the extensor carpi radialis brevis.
Tendon transfers to the extensor carpi radialis brevis (ECRB) are often performed to augment wrist extension. This study was conducted to analyze how transfer of the extensor carpi ulnaris (ECU) to the ECRB affects the moment arms, force-generating capacity, and moment-generating capacity of the ECU over a range of wrist flexion-extension. A graphics-based computer model was developed from anat...
