The Use of Montage Bone Putty in Assisting in the Maintenance of Reduction in Comminuted Distal Radius Fractures.

Background  The distal radius fracture is the most common fracture in the United States. Achieving stable reduction and fixation of complex fracture patterns can be challenging. In order to help maintain reduction of comminuted fracture to simplify plating, the calcium phosphate-based bone putty Montage has been developed. Questions/Purposes  Does Montage assist in achieving stable reduction and fixation of complex distal radius fractures with an acceptable complication profile? Patient and Methods  We retrospectively analyzed all patients who were treated intraoperatively with Montage bone putty along with volar plate fixation at a large-volume urban county hospital. Preoperative, intraoperative, and postoperative measurements of radiographic features were recorded at 2 and 6 months, as were any complications. Statistical analysis was then performed on these values. Results  Preoperative and postoperative radiographs demonstrated significant improvement in standard distal radius fracture measurements, reflecting adequate reduction with the use of Montage intraoperatively. Critically, radiographs demonstrated maintenance of reduction compared to intraoperative fluoroscopy images at 2 months, showing short-term stability of the use of Montage in these fracture patterns as well as long-term stability at 6 months in a subset of patients. There were no major complications in this study. Conclusion  In this study, we demonstrate the utility of Montage bone putty for complex distal radius fractures with short-term follow-up and limited long-term follow-up. This initial study underlines its efficacy in maintaining reduction without major complications. Level of Evidence  IV, Therapeutic.
