Triangular fibrocartilage complex (TFCC)
ANATOMY The TFCC is a fibrocartilage-ligament complex which stabilizes the distal radioulnar joint (DRUJ), transmits axial load between the carpus and the ulna, and stabilizes the ulnar aspect of the carpus. The TFCC is comprised of the disc proper (articular disc), meniscus homologue, ulnolunate ligament, ulnotriquetral ligament, proximal ligamentous component, volar and dorsal radioulnar liga...
متن کاملTriangular fibrocartilage complex lesions: a classification.
Based on anatomic and biomechanical studies and review of our clinical experience of the past 10 years, a classification of injuries to the triangular fibrocartilage complex is presented. This classification is based on the clinical examination, routine x-ray films, wrist arthrograms, wrist arthroscopy, and wrist arthrotomy. The classification recognizes both traumatic and degenerative lesions....
متن کاملThe Study of Ulnar Variance with High-Resolution MRI: Correlation with Triangular Fibrocartialge Complex and Cartilage of Ulnar Side of the Wrist
INTRODUCTION Ulnar variance affects the force distribution across the wrist and is related with some ulnar pathologies. Ulnar minus variance is associated with Kienböck’s disease, whereas ulnar plus variance plays an important role in triangular fibrocartilage complex (TFCC) tear and ulnar impaction syndrome. Ulnar variance is measured based on plain radiograph. However, plain radiograph shows ...
متن کاملArthroscopically assisted reattachment of avulsed triangular fibrocartilage complex to the fovea of the ulnar head.
Triangular fibrocartilage complex (TFCC) insertion into the fovea of the distal ulna plays a crucial role in stabilizing the distal radioulnar joint. Consequently, surgical reattachment against avulsion of the foveal TFCC insertion is required to stabilize the distal radioulnar joint. However, because of technical difficulties, no arthroscopic procedure for such a lesion has currently been esta...
متن کاملArthroscopic debridement with and without distal ulnar resection in the treatment of triangular fibrocartilage complex tears.
A retrospective survey for debridement with or without wafer distal ulna resection was performed. Forty six patients responded to a questionnaire on pain, disability and time off work. The mean DASH score decreased from 42 to 28 on average. Thirty two patients were satisfied. The pain was considered severe in 12 patients. There were significant differences in the outcome between debridement onl...
