[Show abstract][Hide abstract] ABSTRACT: Malunited distal radius fractures pose considerable problems, especially for young, active individuals. Surgical correction with osteotomy, bone grafting, and internal fixation with plates and screws has been the treatment of choice. Locked intramedullary fixation is an alternative technique to provide bony stability while minimizing soft tissue irritation in the management of acute distal radius fractures, with acceptable clinical results. The purpose of this study was to describe our experience with the use of an intramedullary device combined with grafting to repair distal radial malunions. This fixation device is inserted through the radial styloid and obtains distal fixation with 3 fixed-angle locking screws.
Thirteen patients underwent distal radius malunion repair with an intramedullary implant and grafting. There were 6 male and 7 female participants with an average age of 51 years (range, 18-72 y). Patients were evaluated at an average follow-up of 24 months (range, 13-38 mo). Clinical outcome was measured by range of motion of the wrist and forearm, and grip strength, and by using the Disabilities of the Arm, Shoulder, and Hand questionnaire. We analyzed radiographs to determine time to union and adequacy of correction.
All of the malunions healed, with an average time to healing of 11 weeks. Patients' average range of motion at follow-up was 56 degrees of flexion, 66 degrees extension, 85 degrees pronation, and 84 degrees supination. Mean grip strength was 83% of the unaffected side, and the average Disabilities of the Arm, Shoulder, and Hand score was 21. Radiographs taken on the latest follow-up showed correction to the following average parameters: 20.6 degrees radial inclination, 11.0 mm radial height, +1.0 mm ulnar variance, and 2.1 degrees volar tilt.
The technique presented in this report demonstrates the effectiveness of an intramedullary nail combined with bone graft or graft substitute in repairing malunited fractures of the distal radius. The results show reliable correction of the deformity and good functional outcomes.

[Show abstract][Hide abstract] ABSTRACT: Fracture of the distal radius is a common injury and treatment varies depending on the fracture, patient factors, and surgeon preference. Internal fixation has grown in popularity because it affords increased stability and early motion of the extremity. The desire to provide stable fracture support while minimizing soft tissue dissection and complications has led to the development of new intramedullary implants. These implants use distal screw divergence for subchondral support, fixed-angle screws locked to the implant, and minimally invasive technique to allow early patient rehabilitation. Early results of these intramedullary devices are promising but require longer followup. Level of Evidence: Level IV (expert opinion).

[Show abstract][Hide abstract] ABSTRACT: The purpose of this article is to describe a novel technique and implant system for fixation of unstable (Arbeitsgemeinschat fur Osteosynthesesfragen Types A and B) distal radius fractures. Currently the most common complications directly related to distal radius plate fixation includes tenosynovitis, tendon attrition, and rupture, often necessitating hardware removal. With the advent of this new device, a decrease in soft tissue complication is expected. The implant utilizes the principles of load sharing, subchondral screw divergence, and locked fixed-angle fixation. It is inserted through a small skin incision at the radial styloid and does not further devascularize the fracture fragments. The limited surgical dissection and rigid fracture fixation allow for minimal postoperative immobilization and an early return of function. The authors believe that this system is a valuable addition to the arsenal of distal radius fracture treatment options and can quickly get patients back on the road of recovery.
