Background: The purpose of this study was to investigate the clinical differences between open reduction and plate fixation via a deltopectoral approach with allogenous fibular bone graft and a minimally invasive plate osteosynthesis (MIPO), in Neer's classification two-, three- part proximal humeral fractures.
Methods: In this retrospective study, 77 patients with two-, three-part proximal humeral fractures were treated at two different institutions. Clinical and radiological evaluations were performed in 39 patients, who underwent MIPO at one institution (group A), and 38 patients, who underwent a deltopectoral approach with allo-fibular bone graft (group B) at another institution. The results between the groups were compared.
Results: The MIPO technique was significantly less time consuming and caused less bleeding than the deltopectoral approach with allo-fibular bone graft (P<0.05). The duration of the fracture union was significantly reduced in group A (14.5±3.4; range, 10?22 weeks) compared to group B (16.4±4.3; range, 12?28) weeks (P<0.05). There were no statistically significant differences between the two groups when evaluating the visual analog scale and Constant scores between the two groups, 1 year postoperatively. In radiological evaluation, there was no difference in radiological outcomes between the two groups. There were no statistically significant differences in malunion between the two groups.
Conclusions: The MIPO technique and deltopectoral approach with allo-fibular bone graft for two-, three-part proximal humeral fractures, show similar clinical and radiological results. However, allogenous fibular grafts require longer surgery, cause more bleeding, and result in longer fracture healing time than MIPO technique.
