IntroductionNon-union after humeral shaft fractures are seen frequently in clinical practice. The incidence is 2-10% after conservative management and up to 30% after surgical treatment. The purpose of this study is to evaluate the outcomes of plate-and-bone-strut-allograft technique with bone chip augmentation for aseptic non-unions of the distal third of the humerus.Materials And Methods26 consecutive cases were treated using a trans-triceps approach. The non-union was fixed with a 4.5 mm Locking Compression Plate combined with a strut bone allograft at the anterior part of the humerus and bone chips. All patients underwent the same rehabilitation protocol of 12 weeks. Clinical evaluation took place 12 months after surgery with the Mayo elbow score and Oxford elbow score.ResultsComplete bone healing without complications was achieved in all 26 patients. The average period of radiographic union was 106 days. The average range of flexion-extension was 108° (94°-180°) and pro-supination was 159° (102°-180°). Twelve months after surgery, average Mayo elbow score was 86 (68-100) and the Oxford elbow score was 83 (52-100).ConclusionThe plate-and-bone-strut-allograft technique with bone chip augmentation in distal humeral shaft for aseptic non-unions resulted in union of all cases. No adverse events related to the surgery or the materials used were documented.© 2019 Delhi Orthopedic Association. All rights reserved.
