Background Review of the effectiveness of different methods used to repair clavicle injury allows for identifying rational aspects of treatment factors that would directly reflect key pathogenetic mechanisms. A greater part of surgical treatment options have been reported to lead to faster recovery of the patients’ structural and functional stereotypes in majority of the cases. Purpose Improve outcomes of surgical treatment of middle-third clavicle fractures. Material and methods Experimental bench tests of various osteosynthesis technologies using original interlocking intramedullary nail for clavicle fracture and a clinical study of 104 patients with middle-third clavicle fractures were carried out. Original IM nail was applied to repair clavicle fracture in index group (n = 48) and the fractures were plated in control group (n = 56). The DASH questionnaire was used to evaluate results of surgical intervention at 3, 6 and 12 months. Results Original IM nail and plate with angular stability showed comparable characteristics in stability. Original compression interlocking intramedullary nail offered to treat middle-third clavicle fractures showed improvements in outcomes of the patients. Discussion The algorithm developed for diagnosis, treatment and rehabilitation of clavicle fractures showed better results of treatment providing easier social reintegration into everyday life. Clinical findings demonstrated significantly improved DASH scores and lower complications rate in index group (p = 0.038).

Introduction. Study of different treatments effectiveness of these injuries allows to distinguish the rational side of medical factors, which directly reflect the key pathogenetic mechanisms. A substantial portion of the currently used methods of clavicle fractures surgical treatment allow one to achieve rapid recovery of structural and functional patterns of the patient in most cases.The purpose of the study is to improve the results of surgical treatment of patients with fractures of the clavicle in the middle third. Material and methods. The study included 104 patients with fractures of the clavicle in the middle third.In the main group (48 patients) the clavicle lockable rod of the original design was used for osteosynthesis, in the comparison group (56 patients) plate osteosynthesis was performed.Results and discussion. The proposed technology of operative treatment of clavicle fractures in the middle third using the original hip compression-locking rod must improve the results of treatment in this group of patients. The developed algorithm of diagnostics, treatment and rehabilitation of patients with clavicle fractures allows to improve the results of treatment, provides domestic and social reintegratie patients. Conclusion. Analysis of the clinical studies results have revealed a reliable advantage of the results on a scale DASH and a lower frequency of complications in the main group (p
