The use of biodegradable implants in the fixation of small animal cancellous bone fractures.

In this study the cancellous bone fractures of 10 dogs and 2 cats were surgically treated with biodegradable implants to fixate the fractures. The implants were made of selfreinforced PGA homopolymers. The patients were allowed to walk on their operated limbs immediately after the fixation and they started to use them within one week. All patients except one used their operated limbs without lameness in 6 weeks and the twelfth case in 8 weeks, due to a postoperative periosteal infection. Radiographically, the fractures of 10 patients healed in 6 weeks and in 12 weeks in 2 cases. No other pathological reactions in the bone could be seen in the radiographs than the periosteal infection. Because the implants resolved spontaneously there was no need for a second operation to remove them.
