Abstract
ABSTRACT:
The present clinical study was conducted on 11 dogs with supracondylar fractures of the femur presented for treatment at Teaching Veterinary Clinical Complex, Bhoiguda and Campus Veterinary Hospital, College of Veterinary Science, Rajendranagar, Hyderabad. Out of the 11 dogs, 6 dog were males and 5 were females. Out of 11 dogs 6 dogs (54.5%) were in the age group of 0-6 months and 2 dogs (18.18%) were in the age group of 6-12 months, and 2 dogs were in the age group of 12-18 months and 1 dog was (9.09%) more than two years of age. The causes were found to be automobile accident in 4 (36.36%) dogs, fall from a height in 5 (45.45%), stamping by its owner in 2 (18.18%) dogs. The dogs presented for treatment of supracondylar femoral fractures exhibited symptoms like sudden onset of pain and lameness immediately after a traumatic injury, swelling in the stifle area, dangling of the limb, non-weight bearing, abnormal angulation of the limb at the fracture site and crepitation. Radiography revealed that all the supracondylar femoral fractures were transverse fractures, except in one dog, where the fracture was found to be short oblique in orientation. The supracondylar fractures were treated with cross pinning in 10 dogs and intramedullary pinning combined with cross pinning in one dog.
Post-operative radiographs taken immediately after the surgical correction and immobilization of the fractures revealed good anatomical reduction and immobilization of the fracture site in nine dogs and good alignment albeit with a perceptible gap at the fracture site in two dogs. The present clinical study indicated that supracondylar fractures of femur in dogs is most commonly encountered in young dogs, with a majority of them occurring in puppies below 18 months of age. The results of the present clinical study conclusively proved that cross pinning technique is well suited for the surgical repair of supracondylar fractures of femur in dogs. The techniques employed also fulfilled the concept of adaptation osteosynthesis that is meant to preserve and protect the growth plates or physis with the use of weak implants.The complications encountered were consequent to implant failure resulting from repeated trauma in one dog and hyperactivity and excessive excitable nature in two other dogs. The present study indicated that cross pinning technique is well suited for surgical repair of supracondylar fractures of femur in young dogs.
