Antegrade humeral lengthening using a motorized intramedullary telescopic nail: A technical note and results on a series of patients.

Abstract

The use of an electromagnetic motorized intramedullary telescopic nail (MITN) simplifies humeral lengthening in patients with significant shortening. We conducted a retrospective single-surgeon series of five adult patients (2017-2022) with humeral length discrepancies treated using an electromagnetic-controlled MITN. All patients underwent an antegrade approach. In four cases an extended lengthening technique exceeded the 5 cm limit of the 8.5 mm MITN. All patients achieved the planned length, were satisfied with the outcome, and regained their preoperative shoulder range of motion by the end of treatment. Motorized intramedullary humeral lengthening is an effective treatment option for humeral length discrepancies.
