Background: Several methods have been used in the management of humeral nonunions. With the advent of modern microsurgical techniques, vascularized bone grafting is becoming increasingly used to improve local biology. We report our experience in the use of a vascularized corticoperiosteal bone flap from the medial femoral supracondylar region in the treatment of recalcitrant humeral nonunions. Methods: A retrospective review was performed of all patients treated with this technique over a 4-year period within our institution. Patient demographics, nonunion characteristics, complications, and long-term outcomes were analyzed. Results: Six patients underwent vascularized periosteal graft reconstruction. Prior to this, all had failed an average of three procedures with the length of nonunion ranging from 6 to 68 months. All six nonunions healed by an average of 6.8 months (range 2-12 months). Two patients required additional secondary procedures. Functional outcome improved in all patients as adjudged by disabilities of the arm, shoulder, and hand, Mayo elbow performance, and Constant Murley scores. Conclusions: The vascularized medial femoral condyle corticoperiosteal flap provides an additional treatment option for the management of humeral nonunions.
