Six patients with post-traumatic distal radioulnar joint dorsal instability were treated with dorsal capsular reconstruction. This new technique of reconstruction requires less extensive dissection than the previously described methods in the literature and requires no tendon graft. A total of six patients treated from 1999 to 2001 were included in this study. Two were males and four were females. The average age of patients was 30 years and all the instabilities were secondary to trauma. One of them had associated minimally displaced distal radius fracture. All patients had arthrogram and arthroscopy done before the reconstruction and had no significant triangular fibrocartilage complex injury. The surgery consisted of duplication capsulorrhaphy of the dorsal capsular structures of the distal radioulnar joint. All patients had satisfactory results after the operations in terms of pain relief, range of motion and stability.

Arthroscopic foveal reattachment of triangular fibrocartilage complex: Inside-out technique at specific ulnocarpal anatomical landmarks.

This study evaluates the outcomes of arthroscopic triangular fibrocartilage complex (TFCC) foveal reattachment using an inside-out suture passing through the TFCC at specific ulnocarpal anatomical landmarks to grasp the radioulnar ligaments. Thirty-eight patients with a mean age of 36 years (range 19-54), diagnosed with TFCC injury with distal radioulnar joint (DRUJ) instability, underwent arthroscopic inside-out TFCC foveal reattachment using designated suture sites. At a mean follow-up of 32 months (range 26-44), pain score, range of motion, grip strength, Disabilities of the Arm, Shoulder and Hand (DASH) score, and Modified Mayo Wrist Score all showed significant improvement after surgery.

Objective: To investigate the effectivess of arthroscopic Wafer surgery combined with triangular fibrocartilage complex (TFCC) insertion point reconstruction in the treatment of Palmer type ⅡC combined with typeⅠB ulnar impingement syndrome.
Methods: The clinical data of 14 patients with Parlmer type ⅡC combined with type ⅠB ulnar impingement syndrome who met the selection criteria between July 2021 and April 2024 were retrospectively analyzed. There were 7 males and 7 females with an average age of 43 years ranging from 16 to 59 years.

Comparative study regarding the stability of a proximal ulnar stump with or without distal oblique bundle reconstruction during the Sauvé‒Kapandji procedure: a finite-element analysis.

Department of Orthopedics, Yangpu Hospital, School of Medicine, Tongji University, Shanghai, China.
Background: The most common postoperative complication of the Sauvé‒Kapandji (S-K) procedure is proximal ulnar stump instability. The distal oblique bundle (DOB) is a stable tissue used to stabilize the distal radioulnar joint. This study created finite-element models of the distal oblique bundle (DOB) to determine its effect on the proximal ulnar stump instability encountered during the Sauvé‒Kapandji procedure.
