Evaluation of End-threaded Positive and Negative Profile Intramedullary Pins for Management of Long Bone Fractures in Dogs

Background: Intramedullary pinning (IMP) is the most commonly used internal skeletal fixation technique. Threaded pins (also called Schanz Screws) provide a comparatively better holding strength than non-threaded tipped intramedullary pins. The present study was planned to evaluate and compare efficacy of positive negative profile end threaded in management long bone fractures dogs. Methods: Eleven clients owned dog suffering from fracture bones were randomly divided two groups. Animals group I (n=5) II (n=6) treated with intra medullary pin, respectively. done using 3 5.5 mm diameter under general anesthesia, time taken for surgery, size pin each case noted down.

Result: There no significant difference between groups terms fixation/surgery time, gradual improvement weight bearing postoperatively both mild periosteal callus formation all cases when observed radiographically removed evident an anticlockwise manner Jacob’s chuck key, sedation. complication like implant failure or tract sepsis migration breakage any However, passing distal fragment smoother easier as compared pin.
