Objectives: Frequency of occurrence of forearm deformations developed against the background of a hereditary multiple exostosis (HME) in children reaches 30–80%. The clinical and radiological data of forearm deformities have not been sufficiently researched yet. The purpose of our research is specification of children’s forearm deformities developed against the background of HME.

Methods: Retrospectively and prospectively we selected and analyzed 100 patients with the diagnosis ‘Hereditary Multiple Exostosis’ aged from 2 till 17 years. The assessment of forearm deformations was carried out on the basis of clinical and X-ray methods of research according to reference lines and corners for forearm bones.

Results: It has been revealed that in 100% of the cases functional restrictions and cosmetic defect of forearm take place. Complaints about a pain syndrome were registered in 20% of the cases. We revealed the most often forearm deformations, which be classified as ulna deformities and radius deformities, they include: varus and recurvation of ulna on border of the top and average third (65%); varus of ulna in the average third (9%). As for radius deformities, they include: varus of radius in the average third (20%); varus of radius in the lower third (6%). Both ulna and radius deformities are accompanied with shortening of bones of the forearm (in 100% of the cases) and subluxation or dislocation of the radial head (30%).

Conclusion: The variety of children’s forearm deformations developed against the background of HME implies differentiated approach to the choice of individual techniques of surgical treatment in each case.
