Successful use of autogenous bone graft for the treatment of a radius-ulna nonunion in an amputee dog

Abstract

Universidade Estadual Paulista -Unesp-Jaboticabal  Jaboticabal, SP ABSTRACTFracture nonunions represent important complications in orthopedic surgeries. Nonunion repairs or bone defects are surgically challenging. Our aim was to describe a nonunion case, which was repaired with rapid bone recovery. An 8-month-old male mixed breed dog that has been previously operated was presented to the Veterinary Medical Teaching Hospital of São Paulo State University, with a right radiusulna nonunion and an amputated contralateral forelimb. A cancellous bone graft was collected from a partially amputated limb, in order to correct the nonunion, and used in association with a locking plate. After four weeks, the bone graft had been incorporated into the original bone. Clinical union with good weight bearing was achieved after eight weeks.Keywords: fracture, complication, orthopaedics, surgery, humerus RESUMO As não uniões ósseas representam uma importante complicação nas cirurgias ortopédicas.

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

“…If grafts are infected, it may be necessary to perform an amputation of the affected limb in the worst case. In a study that reported the use of autologous cortical bone graft in the radius of a dog, fusion of the bone was observed postoperatively in two months, and reconstruction was observed in six months 5. In the present study, progress in the fusion of bone, seen radiographically as an enhanced opacity at the boundary of the host bone and the graft, was observed three months after surgery in case 1 and six months after surgery in case 2.…”

In addition, the collapse of the reconstructed diaphysis or loosening of the implant did not occur, which corroborates the role of the graft in providing mechanical support.…”

Successful outcome of distal radius non-union after open fracture osteomyelitis treated by external fixation and bone grafting in a cat: case report

“…Fractures with large bone defects and bone non-union are a serious challenge for both human and veterinary orthopaedics (Minto et al, 2015). The main factors with adverse effect on fracture healing are the impaired blood supply in the fracture line area, presence of foreign bodies, necrotic tissues, bone sequestra, infection, maladaptation of bone fragments and inadequate osteosynthesis technique (Piermattei et al, 2006).…”
