In this report, the use of autogenous fat tissue and operation technique for a case of synostosis existing with a growth deformity in radius-ulna was determined. A male mongrel dog (4-y-old) with a growth deformity in it's right forelimb was used. It was observed that there was a valgus deformity in carpal joint and the paw was subjected to an external rotation of 45°. Synostosis was observed in the distal of radius and ulna by radiographic examinations. The synostosis was separated with the operation under general anaesthesia. Cuneiform osteotomy was performed for the deformity in distal radius and transversal osteotomy was made for distal ulna. Autogenous fat tissue harvested in gluteal region was placed between radius and ulna in order to prevent reformation of synostosis. Radial fixation was performed by placing two cross pins through both distal and proximal fragments, and by means of a bone plate and screws. The dog walked normally in the end of first month. It was determined that fracture union was completed in the end of first month, and synostosis did not reformed. Fixation devices were removed at the end of the fourth month. As a results, cuneiform osteotomy was effective in correction of the deformity of radius and ulna, and usage of autogenous fat tissue was useful in preventing reformation of synostosis.
