[Deformity of the forearm caused by benign bone tumours treated by external fixation.].

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.

[Bone Reconstruction of Autolyzed Antigen-free Allogenic /AAA/ Bone in Children and Adolescents with Benign Bone Tumours.].

The authors describe in detail the preparation of six batches of human AAA/autolyzed antigen-free allogenic bone/ prepared in 1985 to 1988. This bone was administered to a total of 48 children and adolescents aged 6 to 19 years. It was used to fill cavities after metaphyseal connective tissue bone defects /31 x/, solitary bone cysts /10 x/, enchondromas /5 x/ and fibrous dysplasia /2 x/.
