[Surgical correction of angular deformities of the radius and ulna following malunion fractures]

Correction of angular deformities in 14 cases of malunion fractures in the canine radius and ulna is described. Angular deformities were most frequently seen in small breeds of dogs following transverse diaphyseal fractures. The most common disorders were valgus and recurvation. Following preoperative planning and measurement of the components of the deformity, reconstructive osteotomy and stable, internal plate fixation was performed. Postoperative follow up time was approximately 32.9 months. On control, 8 dogs showed no lameness, 4 were slightly lame after exercise and 2 dogs turned out to be permanently lame at the end of the follow up investigation.
