Modified technique of single pin fixation and cross intramedullary pin fixation technique for supracondylar femoral fracture in dogs: A comparative study

The present study was undertaken to evaluate a modified technique of single pin fixation and cross intramedullary pin fixation technique in the management of supracondylar femoral fracture in dogs. The study was conducted in 10 adult mongrel dogs of either sex, divided equally in groups A and B In all the animals, a transverse supracondylar fracture was created in left femur under epidural ketamine and thiopental general anaesthesia In group A, normograde technique of single pin fixation through the mtercondyloidfossa was used to immobilize the fracture, whereas in group B, cross intramedullary pin fixation in the manner of Rush pins was used The two techniques were compared based on intraoperative, clinical and radiological observations and functional status of the test stifle joints Single pin fixation through the intercondyloid fossa was relatively easy, less time consuming and less traumatic, however, it was associated with prolonged lameness and healing time, and more callus formation. Whereas cross pin fixation provided relatively more stability leading to early fracture healing
