Purpose:To determine clinical and radiographic results of iliac bone grafting with Kirschner wire fixation for treatment of scaphoid nonunions. Methods: A total of 13 patients who had scaphoid nonunion treated with iliac bone grafting and Kirschner wire fixation between October 2007 and January 2016 were enrolled as subjects of this study. Their clinical results were evaluated, including range of motion of the wrist joint and modified Mayo wrist score. Radiographic results including lateral intrascaphoid angle and scapholunate angle were also assessed. Results: Bony union was achieved in 11 (84.6%) of 13 cases. Modified Mayo wrist score was improved from 64.0 preoperatively to 87.5 postoperatively. Average intrascaphoid angle was improved from 39.5° preoperatively to 27.2° postoperatively while scapholunate angle was improved from 66.0° preoperatively to 55.1° postoperatively. Conclusion: Iliac bone graft with Kirschner wire fixation provided good clinical and radiographic results. Therefore, iliac bone graft with Kirschner wire fixation can be considered as a good treatment option for scaphoid nonunion.

Prospective Study of Functional Outcome in Scaphoid Non-Union With Kirshner Wire and Autologous Bone Graft

“…[16][17][18] The Union rate of scaphoid non-union treated by Kirschner wire along bone grafting was 84.6%. 19 Our result (88.8%) are comparable with those of other studies of both K-wire and screw.…”

“…Pre and Post operative radiographs were assess for radiological outcome. Fracture union was defined according to the criteria described by Dias 19 and assessed at final follow-up from radiographs at 6 months.…”
