ABSTRACT A tendinous slip originating from the extensor carpi radialis brevis was found bilaterally in a male cadaver. It passed through an independent compartment under the extensor retinaculum, located ventral to its first compartment, before becoming a muscle belly and inserting into the abductor pollicis brevis. The superficial branch of the radial nerve passed superficial to the tendinous slip.
