Fractures Forty-fifty percent of all dogs presenting with traumatic injuries are less than one year old. Active physeal areas are especially vulnerable to trauma (30% of the fractures in young dogs are physeal fractures), but all types of fractures are seen in immature dogs. This presentation will focus on principles of orthopedic surgery in growing dogs less than eight months old. Remember the overriding goal is to restore limb function not just to achieve bone healing. A.Always avoid placing a pin through the proximal femur. The physis will be damaged causing abnormalities of the proximal femur and hip. B.Avoid crossing any physis with a pin since growth will most likely cease and limb shortening or growth deformity may ensue. C.Most fractures heal within 4 weeks in young dogs. Splints work well if adequate reduction can be obtained. Splints must be changed weekly due to limb growth. Place splints so the dog can walk on the leg during healing. Walking preserves muscle tone and stimulate bone healing. D.Plates, circular or standard external fixation systems are preferred methods of fixation since the growth plates can be avoided. E.Try to achieve anatomic reduction of growth plate injuries. F.Activity restriction is imperative since immature bone is soft and implants loosen more easily in young bone than in mature bone. G.Remove splints and external fixation systems as soon as possible to minimize their effect on muscle mass. |
