The extensor retinaculum (dorsal carpal ligament, or posterior annular ligament) is a thickened portion of the antebrachial fascia that holds the tendons of the extensor muscles in place.[1] It is located on the back of the forearm, just proximal to the hand.[2] It is continuous with the palmar carpal ligament (which is located on the anterior side of the forearm).
