Aim: The retrospective evaluation of external fixation as a treatment of choice for fractures of humeral diaphysis.

Material – Method: 24 patients with an equal number of fractures of humerus diaphysis (21 closed, 3 open) were treated with external fixation. Time to bony union, the seriousness and type of complications, the clinical, radiological and functional outcome were evaluated. The minimum time of follow up was six months.

Results: Excellent 20, good 2, fair 1, poor 1. The cause of fair and poor results was limitation of shoulder motion. 22 fractures united within 2–5 months. Complications were 2 cases of non-union, 3 pin-track infections, 3 remanipulations. There was no case of deep infection at the fracture site and no iatrogenic injury of the radial nerve.

Conclusion: The external fixation, used in the treatment of humerus fractures, is a semi-interventional method, easy to apply, well-tolerated by the patient and with very good functional results. It a very good alternative of both the conservative treatment and internal fixation.
