Background. Fractures of the distal humerus occur with an incidence of 5.7 cases per 100,000. Fractures of the capitulum humeri are 0.5–1 % of all fractures of the elbow region and 6 % of all fractures of the distal humerus. This paper presents the experience of the authors in the treatment of patients with this pathology by osteosynthesis of isolated fractures of the capitulum humeri with microscrews and Herbert screws. Materials and methods. We observed 18 patients with fractures of capitulum humeri in the department of microsurgery and reconstructive surgery of the upper extremity of SI «ITO of NAMS of Ukraine» in the period from 2007 to 2012. In 17 cases, minimally invasive osteosynthesis of isolated fractures of the capitulum humeri was performed using microscrews or Herbert screws, and in one case head fragment removal was made. Among operated patients, there were 8 men and 10 women. The age of patients ranged from 12 to 78 years, and was 36.23 ± 22.25 years on average. Patients were treated in different terms after trauma — from 3–4 days to 6 months. Results. The results of treatment were evaluated in 13 patients after fracture consolidation and completion of the rehabilitation program according to Mayo Elbow Performance Score. In our group of patients, there were 46.16 % of excellent results and 53.84 % of good results of treatment. There was no aseptic necrosis of bone fragments after osteosynthesis and no cases of bone nonunion. Final functional outcome was very much influenced by the time that passed from injury to surgery.
