Central tarsal bone luxation in three non-racing dogs

Abstract

SummaryEach of three adult crossbreed dogs suffered a hock injury during regular exercise. A non-weight-bearing lameness and a soft tissue swelling around the tarsus were present in all of them. Additionally dog # 1 on palpation of the calcaneus region exhibited crepitous. Radiographs showed luxation of the central tarsal bone in all three of the animals. Dog # 1 also had a fracture of the calcaneus. Surgical treatment was performed on all of the cases, via a medial surgical approach. The luxated bone was repositioned and attached to the adjacent 4th tarsal bone with a 3.5 mm countersunk lag-screw. The fracture of the calcaneus was stabilized with a 2.7 mm five hole AO-plate. Postoperatively the injured limbs were immobilized with a cast for four to six weeks and exercise was restricted. After cast removal, all of the dogs received physiotherapy. All three hocks regained full function and owners reported normal activity.The successful treatment of central tarsal bone luxation in three non-racing dogs is reported.
