27 patients requiring forearm osteotomy (ulnar shortening or radial shortening osteotomy) were randomized to determine the effect of low-intensity pulsed ultrasound (LIPUS) on bone healing following surgery. Patients were allocated to groups of either postoperative LIPUS therapy or no LIPUS therapy, and were followed-up for up to 24 weeks. Main outcome was radiographic determined bone healing, along with clinical outcome using the Modified Mayo Wrist Score. Results at final follow-up found that significantly faster cortical and endosteal healing occurred in the group who underwent LIPUS therapy, and that both groups experienced a similar improvement in clinical outcome.
