(A) Pre-operative radiographs demonstrating the fracture.
(B) Post-operative radiographs after closed reduction and internal fixation with the Polarus intramedullary nail.
(C) Fourteen weeks follow up radiographs demonstrating healing across the fracture site with 13.1° varus angulation at humeral midshaft. Good function was achieved in this patient.
