Internal fixation of distal femur fracture using cross pin and wire in a terrier dog

A 5 month-old terrier dog with history of falling and sign of clinical lameness in left hind limb with swelling, tenderness and crepitus in palpation was referred to the Veterinary Teaching Hospital of the School of Veterinary Medicine, Razi University. A complete transverse fracture at distal portion of left femur with subluxation of patella has been shown in radiological evaluation. Based on open reduction and internal fixation, fracture's fragments in anatomical alignment had been fixed by using two cross intramedullary pins. For excessive stability of mentioned alignment and reduction, the fracture ends were compressed exactly towards each other by passing an orthopedic wire via figure 8 wiring technique. The following radiographic evaluation confirmed correct insertion of cross pins and proper reduction and fixation of fracture's fragments. Ultimately, the method using pin and wire in surgical treatment of distal femur fracture seemed successful after eight-week exercise restriction and postoperative followings respectively.
