extensor carpi ulnaris tendon2 [Anatomy_22] Septum of the Extensor Retinaculum, wrist MRI The extensor retinaculum originated from the pisiform and passed over the dorsal wrist compartment and attached to the distal radius. The circumferential support of the ECU tendon was provided by the supra-tendinous and infratendinous extensor retinaculum and radial and ulnar retinacular septa supporting the ECU tendon. #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #TFCC, #Wrist M.. 2022. 9. 7. [Anatomy_21] Physiologic displacement of the extensor carpi ulnaris Tendon, Pronation, Supination In the neutral and pronation positions, the ECU tendon is centered in the groove in the distal portion of the ulna. Note the normal tendency of the ECU tendon to sublux to the apex of the ulnar styloid at the ulnar border of the groove during supination. Variations in length of distal extension of the ECU subsheath connecting the ulnar styloid process and superficial ligamentous fibers of the do.. 2022. 9. 7. 이전 1 다음
