Longitudinal radioulnar dissociation is a triad of injuries consisting of distal radioulnar joint disruption, interosseous ligament complex (IOLC) tear, and radial head fracture. This renders the forearm longitudinally unstable, resulting in proximal migration of the radius and ulnar-sided wrist degeneration. We hypothesized that reconstruction of the central band of the IOLC in cadaver forearms using a Mini-TightRope suture-button construct would restore native forearm stability. ⋯ In this cadaveric study, Mini-TightRope IOLC reconstruction with or without a radial head prosthesis significantly reduced distal ulnar impaction forces to that of the native forearm, while limiting radioulnar displacement to near-anatomic levels.

Comparative Study
Management of peripheral triangular fibrocartilage complex tears in the ulnar positive patient: arthroscopic repair versus ulnar shortening osteotomy.
One pattern of injury to the triangular fibrocartilage complex (TFCC) is a traumatic peripheral tear located at the ulnar end of the TFCC. Since 1989, this specific injury has been classified as a Palmer type 1B lesion. Various treatment options have been described for 1B injuries, yet when there is coexistent ulnar positive variance, it can make the choice of treatment difficult. The purpose of this article is to help the surgeon decide how to treat type 1B lesions in ulnar positive patients by directly comparing arthroscopic repair (repair) to ulnar shortening osteotomy (USO). The null hypothesis was that repair and USO would provide equivalent postoperative improvement with regard to motion; Disability of the Arm, Shoulder, and Hand (DASH) score; visual analog scale (VAS) score; and grip strength. ⋯ Therapeutic III.

The aim of this study was to assess thumb survival, pinch strength, grip strength, and need for secondary surgery in patients undergoing thumb replantation after isolated thumb amputation injury. ⋯ Therapeutic IV.

A 37-year-old man sustained a floating distal interphalangeal (DIP) joint injury to the left index finger. The diagnosis was not confirmed until 3 months after the injury because of minimal deformity of the injured finger. Open reduction and internal fixation of the dorsally displaced floating DIP joint was carried out. Bone union was achieved but radiographs revealed osteoarthritis of the DIP joint.
