A Retrospective Comparative Analysis of the Use of Implantable Bone Stimulators in Nonunions


This study details the use of implantable bone stimulators in the setting of nonunion. A retrospective comparative analysis was used to evaluate the efficacy of implantable bone stimulators in achieving union in the setting of atrophic or oligotrophic nonunion by two fellowship-trained orthopaedic trauma surgeons. Initially, 72 patients underwent surgical intervention for nonunion. Twenty-one patients had an implantable bone stimulator placed at the time of nonunion surgery. Thirty-eight patients had a minimum of 1-year follow-up. An implantable bone stimulator was used in 13 patients and 25 patients did not have a bone stimulator. The use of implantable bone stimulators was found to be significantly associated with increased union rates (p D .042).
