The dorsal part of the scapholu..

The commonly used Mayo classification divides carpal instability into four major categories. 1. Carpal instability dissociative (CID), where there is dissociation of the bones in a single carpal row. The proximal carpal row is most commonly affected (i.e., SL instability; lunotriquetral instability). Distal carpal row dissociation is rare. 2. Carpal instability nondissociative includes instabili..

The flexor carpi radialis brevis vel profundus extends from the distal radius to the capitate and base of the third and fourth metacarpals. It passes between the pronator quadratus and FCR muscles. Many accessory muscles have been described in the hand. Most are asymptomatic, but they can be a cause of compressive neuropathy or a palpable soft tissue mass. Detection can be difficult because the ..

Illustration of IB complete tear showed the detachment of both the fovea and the styloid insertions of the TFC. It involves both the foveal and the styloid insertions of the TFC and shows the irregular high signal intensity. Other signs may include altered morphology, focal synovitis, and fluid accumulation. The complete tear is typically associated with DRUJ instability. Theoretically, it may r..

Stage I • Bone marrow edema due to ischemic damage without morphological changes • Normal density of the lunate in radiography and attenuation at CT scan • Low signal intensity on T1-weighted images and usually hyperintense on T2-weighted fat-suppressed images. Stage II • Sclerosis of the lunate bone due to chronic ischemic damage • Increased density in radiography with preserved morphology • CT..

The prestyloid recess is a synovial-lined pouch with a direct connection to the rest of the radiocarpal compartment. It is most commonly a saccular space bordered by the meniscal homologue distally, the TFCC attachments to the ulnar styloid process proximally, and the central TFCC disk radially There are several variations in the shape of the prestyloid recess. Prestyloid recess is best seen on ..

The ulnocarpal ligament, or ulnocarpal ligamentous complex (UCLC), is anatomically divided into the ulnocapitate, ulnotriquetral, and ulnolunate ligaments. 💟 Visit my youtube channel Youtube channel: MSKMRI 💟 Visit my Instagraml: MSK_MRI 🥰 #SubscribeMe, #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #TFCC, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원,#Ulnolunate Ligament,#..

The most important structure of the triangular fibrocartilage complex (TFCC) is the TFC proper. The ulnar structures include the meniscus homologue (MH) and ulnar collateral ligament (ulnar capsule). The volar structures include the volar radioulnar ligament, ulnotriquetral and ulnolunate ligaments. The dorsal structures include the dorsal radioulnar ligament and extensor carpi ulnaris tendon sh..

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..
