title: [Deformity of the forearm caused by benign bone tumours treated by external fixation.].
abstract: A developed deformity of the forearm is usually due to an osteochondroma and has a typical clinical and X-ray appearance. Patients suffering from this disease have a restricted function of the forearm due to shortening of the bones, usually both bones, and in particular girls are aware of the cosmetic and aesthetic loss. The X-ray symptomatology of the deformity is as follows: dislocation of the head of the radius, multiple tumours on both bones which dislocate the bones, ulnar angulation of the radius and ulna, shortening of the ulna, ulnar inclination of the articulation surface of the distal radius, ulnar subluxation of the wrist and shortening of the metacarpal bones. The therapeutic procedure used by the authors is stagewise and comprises the following operations: ablation of the osteochondromas, gradual extension of the ulna, reposition of the head of the radius and correction osteotomy of the distal radius. The objective of the submitted paper is long-term clinical and X-ray evaluation of the forearm deformity after operation. In the majority of patients after treatment radial duction in the wrist remains restricted but this is not important from the functional aspect. The X-ray finding of ulnar subluxation of the wrist frequently improves after extension of the ulna. Key words: osteochondromas, deformities of the forearm, gradual extension of the ulna.
