A three-year-old male working border collie with an infected femoral nonunion fracture was managed in a two-stage procedure involving debridement and omentalisation, followed by stabilisation with a bone plate and an autogenous cancellous bone graft. Osseous union was documented radiographically 16 weeks after surgery. Telephone follow-up one year later revealed the dog had returned to full wor...

Recently we have been performing biological reconstruction for malignant bone tumors of the extremities using frozen autografts. Here we present a case treated with free vascularized fibular graft (FVFG) after this method. A 23-year-old man developed osteosarcoma in his left distal tibia. There was nonunion after frozen autograft reconstruction, which we treated with FVFG. Twenty-four months la...

A 12-year-old castrated Toy Poodle was referred to the Kangwon National University Animal Hospital with an oligotrophic nonunion fracture in the distal 1/3 of the left radius and an intact ulna. After fixation by a locking plate and screws, adipose-derived mesenchymal stem-cell sheets expressing bone morphogenetic protein 7 (BMP-7) were transplanted to the fracture site to enhance the healing a...

Nonunion can occur relatively frequently after scaphoid fracture and appears to be associated with severity of injury. There have been a number of techniques described for bone grafting with or without screw fixation to facilitate fracture healing. However, even with operative fixation of scaphoid fractures with bone grafting nonunion or malunion rates of 5 to 10 percent are still reported. Thi...

The authors compare the functional outcome of 8 patients treated by distal scaphoid resection arthroplasty for scaphoid nonunion with symptomatic wrist arthritis before surgery and after a minimum follow-up of 6 months. There was a significantly better range of radial deviation and grip strength at the time of re-examination. Significantly fewer patients complained of resting pain. By contrast ...

The authors present a rare technique of tension band plating of the anterior tibia in the setting of a nonunion stress fracture. Surgical management with an intramedullary nail is a viable and proven option for treating such injuries. However, in treating elite athletes, legitimate concerns exist regarding the surgical disruption of the extensor mechanism and the risk of anterior knee pain asso...
