[Wrist_02] Scapholunate ligament tear and Dorsal capsulo-scapholunate septum tear https://youtu.be/R_DCrdBY9Pg https://www.instagram.com/msk_mri/ MSKMRI(@msk_mri) • Instagram 사진 및 동영상 팔로워 1,850명, 팔로잉 84명, 게시물 194개 - MSKMRI(@msk_mri)님의 Instagram 사진 및 동영상 보기 www.instagram.com The scapholunate ligament (SLL) is a C-shaped structure, and has 3 histologically and functionally distinct components, dorsal, volar and proximal (interosseous) components. The dorsal part of the scapholu.. 더보기
[Wrist_01] Madelung deformity, carpal instability adaptive, Vicker’s ligament 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.. 더보기
[Wrist/Finger_Case_#04] flexor carpi radialis brevis vel profundus, accessory muscle 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 .. 더보기
[Wrist/Finger_Case_#03] Palmer classification IB3. Complete avulsion, TFCC tear, anatomy 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.. 더보기
[Wrist/Finger_Case_#02] Kienböck's disease 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.. 더보기
[Anatomy_26] Prestyloid Recess, ulnotriquetral ligament, Ulnomeniscal Homologue -02 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 .. 더보기

[Anatomy_24] Carpal Ligaments, Triangular fibrocartilage complex (TFCC), wrist MRI 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,#.. 더보기
