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..

ECU subsheath connected the ulnar styloid process and superficial ligamentous fibers of the dorsal radioulnar ligament. So, The subsheath of the ECU tendon maintains the stability of the dorsal aspect of the TFCC it is necessary to learn about the ECU subsheath. The extensor retinaculum is an important and complex structure, preventing extensor tendons bowstringing. The extensor retinaculum cour..

The fibers at the main insertion into the ulnar aspect of the triquetrum are recognized between the triquetrum and the ECU tendon. Some fibers attach to the ulnar aspect of the pisiform (P), forming the dorsal capsular ligament of the pisotriquetral joint. The entire distal insertion was clearly separated from the volar extrinsic ligaments. #WristMRI, #WristAnatomy, #WristLigament, #WristInstabi..

(Styloid component) this component is recognized between the entrance to the prestyloid recess and the the extensor carpi ulnaris tendon (ECU). (Collateral component), UMH, the ECU tendon sheath, and the joint capsule (ulnar collateral ligament) is fused indistinguishably. (Distal insertion) The ulnar aspect of the triquetrum represented the main insertion site. #WristMRI, #WristAnatomy, #WristL..

The ulnomeniscal homologue (UMH) is noted slightly ulnar to the origin of the dorsal radioulnar ligament and radioulnar component of the UMH. The radioulnar component of the UMH arose at the dorsal radioulnar ligament of the TFC complex. The distal insertion of the UMH is seen with its main body attaching to the triquetrum #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #TFCC, #Wris..

At the level of the origin of the dorsal radioulnar ligament, radioulnar component of the ulnomeniscal homologue (UMH) is noted. The radioulnar component of the UMH arose at the dorsal edge of the radial notch, together with the dorsal radioulnar ligament of the TFC complex. The broad ligamentous structure attaches to the dorsal edge of the radial notch and divides into the proximal and distal l..

The volar and dorsal aspects of the attachment correspond to slip insertions of the radioulnar ligaments into bone. The central portion of the attachment appears as an insertion into the hyaline cartilage of the radius The triangular fibrocartilage or articular disc of the TFCC has a broad attachment to the hyaline cartilage of the sigmoid notch of the distal radius, whereas, the dorsal and vola..
