The effect of single plate and double plate application on union and functional results in humeral diaphyseal nonunions.

In this study, we assessed and compared the outcomes of two different fixation techniques for humeral diaphyseal fracture nonunions. A retrospective evaluation of 22 patients who underwent single-plate and double-plate fixation due to humeral diaphyseal nonunions was conducted. Union rates, union times, and functional outcomes of the patients were assessed. There was no significant difference between single- plate and double-plate fixation in terms of union rates or union times. The double-plate fixation group achieved significantly better functional outcomes. Nerve damage or surgical site infection were not encountered in either group.Due to its considerable effect on stability, double-plate fixation, offers both patients and surgeons confidence in terms of early adaptation to daily life in the postoperative period.
