Background:
Treatment of forearm fracture nonunion is challenging. Several surgical techniques for the treatment of forearm nonunion have been reported.
Objectives:
The aim of this prospective study was to evaluate the effects of the radial forearm bone graft technique in cases with forearm nonunion.
Patients And Methods:
We treated 7 patients with forearm nonunions via radial forearm bone flap and internal plate fixation. On the preoperative examination and last follow-up, the quick disabilities of the arm, shoulder, and hand (Q-DASH) score, elbow, forearm and wrist arches of motion and grip force were measured. At the final follow-up, radiographic union and patient satisfaction and return to work were assessed.
Results:
The mean follow-up duration was 34 ± 23 months. The Q-DASH scores improved from 70 ± 6 points preoperatively to 13 ± 15 points at final follow-up (P < 0.01). The preopetative range of motion (ROM) was 101 ± 26 degrees; whereas the final forearm ROM was 140 ± 17 (P = 0.01). All nonunions united uneventfully (range 3-6 months). At the last follow-up, the grip force was 83% of uninjured extremity and all patients were satisfied with the outcome of the operation.
Conclusions:
Radial forearm bone flap is a safe, useful and novel technique in cases with forearm nonunion.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
