Successful centralisation technique for treatment of post-traumatic absence of the radial shaft in a dog.

This report describes a centralisation procedure for the treatment of a radial non-union, characterised by extensive bone loss and an intact ulna, in an 18-month-old toy poodle. A lateral approach to the radius/ulna shafts was realised and, after debridement of the non-union site, an ulnar osteotomy was performed proximal to the styloid process of the ulna. Transposition of the distal fragment of the radius to the distal end of the osteotomised proximal segment of the ulna was performed and the stabilisation was obtained using a locking plate with proximal screws in the ulnar shaft and distal screws in the radius epiphysis.

Long-term outcomes of atrophic/oligotrophic non-unions in dogs and cats treated with autologous iliac corticocancellous bone graft and circular external skeletal fixation: 19 cases (2014-2021).

Objectives: To determine the short- and long-term outcomes and complications in dogs and cats undergoing surgical treatment for viable oligotrophic and nonviable atrophic non-unions using circular external skeletal fixation and autologous corticocancellous bone graft.

Materials And Methods: In this case series, the medical records and radiographs of all dogs and cats with radius/ulna and tibia/fibula viable oligotrophic and nonviable atrophic non-unions treated with corticocancellous bone graft and circular external skeletal fixation at two referral veterinary hospitals between 2014 and 2021 were retrospectively reviewed. The long-term follow-up was 1 year or greater.
