Fleischhacker E, Siebenbürger G, Helfen T, et al. - This study was undertaken to investigate functional outcomes in patients with varus malposition following open reduction and internal fixation of displaced proximal humeral fractures. Researchers examined data of 685 patients with a mean age of 67±15.8 years (67% female), that were treated by open reduction and internal fixation for a displaced proximal humeral fracture at a level 1 trauma center. For proximal humeral fractures, varus malposition is related to inferior functional outcomes compared to anatomic healing in patients treated by open reduction and internal fixation. The outcomes guide the suggestions to prevent varus malposition in open reduction and internal fixation. The revision surgery should be considered in severe >20° of varus malposition.
