Abstract

New design interlocking nail and plate fixation was used in comminuted femur fracture in an old dog that the results showed primary bone healing and she had been quickly weight baring in fifteenth day after surgery, and could be walk in twenty day after operation. Another case was a young dog that showed transverse fracture of both humerus and one transverse fracture of femur that were repaired by intramedullary pin and external skeletal fixation. The results showed secondary bone healing of these three bone fractures and she could be walk after 2 months of operation. An old dog did not show any complication but a young dog showed pin migration in femur healing. This study revealed that the superior result in bone healing was found in rigid fixation by new design interlocking nail and plate fixation greater than intramedullary pin with external skeletal fixation.

Summary

Introduction

Canine long bone fracture (humerus, femur, radius, and ulna) are the common problems in vehicular accident in street dogs of Thailand. Internal fixation by intramedullary pin, interlocking nail, wire, plate, and screw device are the suitable methods for long bone fracture repairing unless complicated wound happening. Two cases in this report reveals internal fixation by new design interlocking nail that was not use specific instrument when use its combination with wire, and plate fixation in 16year-old dog with comminuted femur fracture. Another case was 4-month-old dog with both humerus transverse fracture and one femur transverse fracture were repaired by intramedullary pins and external skeletal fixation. Two dogs were different in ages, pattern of long bone fractures, and fixation repairing method
