| dc.description.abstract | ABSTRACT : The present clinical study was conducted on 18 dogs with humeral fractures presented for surgical treatment. Out of the 18 dogs, 14 were males and 4 were females. They were in the age group of 3 months to 7 years. Routine clinical examination, radiographic examination, surgical instruments and procedures were used for diagnosis and treatment of these dogs. Out of the eighteen dogs that were treated surgically, thirteen dogs with transverse humeral fractures underwent intramedullary pinning, three dogs with oblique fractures were treated with intramedullary pinning combined with cerclage wiring. In the remaining two dogs, one with transverse supra condylar fracture, and one with inter condylar fracture, closed reduction and external coaptation (cast) was adopted. The causes were found to be automobile accidents in 6 dogs, fall from a height in 10 dogs, stamping by its owner in 1 dog and blunt trauma caused by a stranger in 1 dog. Study of the breed wise incidence revealed humeral fractures in 3 mongrels, 7 German Shepherds , 2 Labrador, 5 Spitz and 1 Pug. The symptoms of humeral fractures were found to be pain, swelling over the humerus area, loss of function and crepitation at the fracture site. In all the dogs, the function of the affected limb was lost and non-weight bearing and varying degrees of limb swelling was noticed. The dogs with humeral fractures carried the affected leg with the elbow dropped and with the paw resting on the dorsal surface. The dogs dragged the limb while walking. None of the dogs exhibited any neurological deficit. The dogs with mid shaft fractures of humerus showed considerable angular displacement of distal segment. In the 13 dogs that underwent intramedullary pinning for transverse mid shaft and distal shaft fractures of humerus, satisfactory alignment of fracture segments with good union was seen by a bridging callus with minimal periosteal reaction in 12 dogs at the end of 4 weeks of surgery. A large bridging callus with fine radiolucent line was observed in one dog on 30th postoperative day. In 3 dogs, proximal migration of pin was noticed . Normal healing ensued following removal of pins in all the dogs. Postoperative radiographic examination of 3 (16.66%) dogs that underwent intramedullary pinning combined with cerclage wiring revealed normal bone healing with retention of oblique fracture ends in place, held snugly by the cerclage wire. Radiograph on 45th postoperative day showed good alignment of fracture, healed fracture with moderate callus formation and slight periosteal reaction at caudal surface of the fracture of humerus. Post reduction radiographic examination in 2 dogs with transverse supracondylar fracture of humerus in one dog and intercondylar fracture of humerus in another dog, treated by external coaptation revealed satisfactory fracture healing and good alignment of fracture. In the dog with supracondylar fracture, excessive callus around the fracture site was observed. Post reduction radiographic examination at 5 months in the other dog with wide separation of the condyles revealed normal bone healing. The following conclusions were drawn from the results of the present clinical study: 1. Out of the eighteen dogs in the present study, transverse fracture of humeral shaft was noticed in 13 dogs ( 72.22 %), oblique fractures of the humeral shaft in 3 dogs (16.67%) and supracondylar and intercondylar fractures of the distal humerus was noticed in one dog each. 2. These fractures were amenable to treatment with intramedullary pinning in cases of transverse shaft fractures of humerus and by intramedullary pinning combined with cerclage wiring in oblique fractures. Supracondylar and intercondylar fractures healed well by coaptation and Robert Jone’s cast application. 3. No major complications were encountered. The minor complications in three dogs were proximal migration of the pin with a seromatous swelling that disappeared following removal of the pin, thus rendering the complications insignificant. | en_US |
