wafer distal ulna resection for Triangular Fibrocartilage tears and or ulna impaction syndrome
Journal of Hand Surgery (European Volume), 1992Co-Authors: Paul Feldon, Andrew L. Terrono, Mark R. BelskyAbstract:Partial resection of the distal ulna (wafer resection) has been used to treat patients with symptomatic tears of the Triangular Fibrocartilage complex or mild ulna impaction syndrome. In this procedure, the distal 2 to 4 mm of the distal ulnar head is resected while preserving the ulnar styloid process and the ligaments attached to it. The Triangular Fibrocartilage is debrided, repaired, or partially excised as necessary. The procedure is contraindicated if there is more than 4 mm of positive ulnar variance. Thirteen wafer resections of the distal ulna were performed in 12 patients. All had good to excellent results after a minimum follow-up of 1 year. Wafer resection has specific advantages and avoids many of the potential complications of distal ulna recession and ulnar head resection for patients with the conditions described. The procedure is not indicated if instability or degenerative arthritis of the distal radioulnar joint is present or if there is carpal instability.

Arthroscopic Triangular Fibrocartilage complex debridement using radiofrequency probes.
Journal of Hand Surgery, 2005Co-Authors: Nickolaos A. Darlis, Robert W. Weiser, Dean G. SotereanosAbstract:The initial results of using radiofrequency probes for debridement of a torn Triangular Fibrocartilage complex were studied in 20 patients with a mean age of 44 (range 27–56) years presenting with ulnar-sided wrist pain. On arthroscopic examination, 18 central and two radial Triangular Fibrocartilage complex tears were identified and debrided to a stable rim using radiofrequency probes. The mean follow-up was 22 (range 9–35) months. Seventeen patients experienced substantial pain relief. In three, the pain was unchanged. The mean flexion extension arc was 132°, pronosupination arc 155° and mean grip strength was 83% of that of the unaffected side. Using the modified Mayo wrist score, there were ten excellent, seven good and three fair results. No perioperative complications occurred. Radiofrequency probes were found to be safe and effective for use in Triangular Fibrocartilage complex debridement. These results compare favourably with other standard methods of treatment of this problem.

suture anchor repair of ulnar sided Triangular Fibrocartilage complex tears
Journal of Hand Surgery (European Volume), 2003Co-Authors: Kent H Chou, Ioannis Sarris, Dean G. SotereanosAbstract:Traditional open repair of traumatic Triangular Fibrocartilage complex (TFCC) tears requires a relatively extensive exposure, and arthroscopic repair, though conceptually simple, can be technically demanding. We describe a mini-open suture anchor technique that, while minimally invasive, is easier to perform than previously described open or arthroscopic techniques. Results achieved using this technique in eight cases compare favourably with those reported for other techniques.

Acute blocking of forearm supination secondary to tearing of the Triangular Fibrocartilage complex.
The Journal of hand surgery European volume, 2020Co-Authors: Taku Suzuki, Toshiyasu Nakamura, Yoshihiko Tanino, Yukihiko Obara, Yasuhiro Yoshikawa, Takuji IwamotoAbstract:We studied the characteristics of acute blocking of supination of the distal radioulnar joint caused by Triangular Fibrocartilage complex injuries. Twenty-four patients who were treated for acute blocking of supination were retrospectively assessed. Supination was suddenly blocked after minor trauma to the wrist. Active and passive supination was severely restricted with a mean preoperative range of motion (11°), whereas pronation was almost normal. The cause was identified arthroscopically or at open operation. It was found to be a result of avulsion of the dorsal or palmar portion of the radioulnar ligament, which blocked movement of the ulnar head. Blocking was reduced manually in four cases, by arthroscopic surgery in eight cases and by open surgery in 12 cases. After treatment, forearm supination improved to 84° of the mean range of motion. Distal radioulnar joint blocking from a ruptured Triangular Fibrocartilage complex should be considered in the differential diagnosis of loss of forearm supination.Level of evidence: IV.

How Does Ulnar Shortening Osteotomy Influence Morphologic Changes in the Triangular Fibrocartilage Complex
Clinical Orthopaedics and Related Research®, 2014Co-Authors: Yoshiaki Yamanaka, Toshiyasu Nakamura, Kazuki Sato, Yoshiaki ToyamaAbstract:Background Ulnar shortening osteotomy often is indicated for treatment of injuries to the Triangular Fibrocartilage complex (TFCC). However, the effect of ulnar shortening osteotomy on the changes in shape of the TFCC is unclear. In our study, quantitative evaluations were performed using MRI to clarify the effect of ulnar shortening on Triangular Fibrocartilage (TFC) thickness attributable to disc regeneration of the TFC and TFC angle attributable to the suspension effect of ulnar shortening on the TFC.

Radial Side Tear of the Triangular Fibrocartilage Complex
Arthroscopic Management of Distal Radius Fractures, 2010Co-Authors: Toshiyasu NakamuraAbstract:Distal radius fracture induces various soft tissue disruptions. Radial tear of the Triangular Fibrocartilage complex (TFCC) is a typical soft tissue injury associated with the distal radius fracture. The radial tear of the TFCC includes Fibrocartilage central tear and dorsal or palmar rim tear; the latter two may induce distal radioulnar joint (DRUJ) instability [3]. Intrafibrocartilage tear of the TFC may not be associated with DRUJ instability. When the DRUJ indicates severe instability in the radial tear of the TFCC, the rim area must be repaired, as opposed to the tear inside the Fibrocartilage area which just needs arthroscopic partial resection.

Dorsoradial avulsion of the Triangular Fibrocartilage complex with an avulsion fracture of the sigmoid notch of the radius.
Journal of Hand Surgery (European Volume), 2007Co-Authors: Yasushi Morisawa, Toshiyasu Nakamura, Kenichi TazakiAbstract:We report two extremely rare cases of dorsal radial avulsion injury of the Triangular Fibrocartilage complex accompanied by an avulsion fracture of the sigmoid notch of the radius. Anatomical reduction of the bone fragment in conjunction with reattachment of the dorsal portion of the radioulnar ligament to the radial sigmoid notch were necessary to restore stability of the distal radioulnar joint and tension of the Triangular Fibrocartilage proper.

Open repair of the ulnar disruption of the Triangular Fibrocartilage complex with double three-dimensional mattress suturing technique.
Techniques in hand & upper extremity surgery, 2004Co-Authors: Toshiyasu Nakamura, Kazuki Sato, Yasushi Nakao, Hiroyasu Ikegami, Shinichiro TakayamaAbstract:Open repair technique of the ulnar disruption of the Triangular Fibrocartilage complex is described. This technique is indicated for a fresh or a relatively fresh (less than 1 year after the initial injury) ulnar foveal detachment tear, horizontal tear, and proximal slit tear of the Triangular Fibrocartilage complex, all of which are accompanied by severe dorsal, palmar, or multidirectional instability of the distal radioulnar joint. A chronic tear greater than 1 year from initial injury and a fresh Triangular Fibrocartilage complex tear without distal radioulnar joint instability, such as central slit tear, are excluded from our indications. A dorsal C-shaped skin incision, a longitudinal incision of the radial edge of the extensor carpi ulnaris subsheath and the dorsal distal radioulnar joint capsule, exposes the distal radioulnar joint. A small, 5-mm longitudinal incision at the origin of the radioulnar ligament exposes its fovea detachment and/or the proximal slit tear of the Triangular Fibrocartilage complex. The disrupted radioulnar ligament is sutured in a pullout fashion to the ulna with a 3-dimensional double mattress technique through 2 bone tunnels that is precisely made at the central portion of the fovea with 1.2-mm K-wire. An additional horizontal mattress suture is used for closure of the small incision made at the radioulnar ligament, then the extensor carpi ulnaris is repaired. This open-repair technique is complex and requires precise technical skills; however, early results have been more rewarding than the conservative treatment.
