Osteogenesis details depending on intermediate fragment location for humeral double fractures

The article deals with the results of treatment in 40 patients with double humeral fractures. Consolidation of fragments was achieved in 36 patients. Immediate results were unsatisfactory in four cases; that is why it was required to perform reosteosynthesis in two cases, cast immobilization - in one case, and one patient rejected surgical treatment. In addition, patients' x-rays have been analyzed and compared with the plan of humeral blood supply to reveal failure causes. It was found that three unsatisfactory results out of four ones were noted in the group of patients in whom the intermediate fragment and both fracture lines were located over the middle third of humeral shaft. The suggestion has been substantiated that this is connected with the site of intermediate fragment location, as well as with the entrance level and bone localization of nutrition artery and its branches. On the basis of significant number of cases, the groups of patients with humeral double fractures were singled out; the form and degree of vascularization disorder in the intermediate fragment have been proposed. It should contribute to predict the character of fracture consolidation process in patients of this category.
