    ABSTRACT: The present study was conducted on thirteen clinical cases with distal femoral fractures to study the use of two internal fixation techniques namely Positive Profile, End Threaded, Selftapping, Intramedullary pinning and Cross pinning and to compare the postoperative fracture healing implant related complications pertaining to these techniques. History, signalment, clinical evaluation, haematological, biochemical and radiographic evaluation and clinical outcome were recorded in all the cases. The animals were randomly divided into 2 groups. In Group I, the fractures were stabilized by Positive, Profile, End Threaded, Self-tapping, intramedullary pinning and in Group II, the fractures were stabilized by Cross pinning using K-wires. In Group I, the 60th postoperative day radiographs of dogs 1, 3, 4, 5, 6, 7 revealed complete fracture healing with no evidence of fracture line along with cortical and medullary continuity and signs of remodeling. In Group II, the 60th postoperative day radiographs of all the dogs revealed complete healing of fracture with cortical and medullary continuity with no evidence of fracture line. In Group I, complete weight bearing on the operated limb while walking and standing was seen by 5th postoperative day in majority of dogs. In Group II, complete weight bearing on the operated limb while walking and standing was seen by 15th postoperative day in majority of the dogs. In Group I, there was only one complication of osteomyelitis (dog 2), where as in Group II, two dogs (4 and 6) showed implant related complications like pin migration and dislodgement of pins and in dog 3, medial luxation of patella on 15th postoperative day was noticed without adverse effect on clinical outcome. Based on weight bearing patterns and radiographic evaluation of fracture healing the clinical outcome was excellent in six cases and poor in one case of group I and in group II, the clinical outcome was excellent in all cases. Cross pinning technique had more implant related complications than PPETST intramedullary pinning with no adverse effects on fracture healing.
