Application of autologous cortical bone grafts for femoral non‐union fractures in two dogs

Abstract

Two dogs with non-union fractures and osteomyelitis in the femoral diaphysis were referred to the authors’ hospital. During surgery, the defects were reconstructed using autologous cortical bones harvested from the contralateral femoral diaphysis. Graft fixation was performed by a double-plate technique in both cases. Autogenous cancellous bone was also grafted between the host bone and the graft in both cases. Antibiotics were administered for two to three weeks. In cases 1 and 2, no loosening of the implant or lameness was observed after 31 months and 10 months, respectively. Autologous cortical bone grafts are useful in reconstructing large-sized bone defects of the femoral diaphysis associated with non-union fracture and osteomyelitis.

Use of 3-D Models for Surgical Planning of a Malunion in a Dog

“…The proximal and distal fragments were stabilized with an intramedullary pin, and two locking plates were laterally applied. A double-plate fixation method has been reported to provide increased stability against rotation and flexion [17][18][19][20]. Consequently, bone union was confirmed four months after surgery, and no postoperative complications were observed 11 months after surgery.…”
