An angular limb deformity is a condition that results from the abnormal growth, or stunted growth, of one or more long bones, usually in the front legs of a young dog.Angular limb deformities can be caused by the premature closure of a growth plate (called a “physis”), by retained cartilaginous cores or by bony bridging (synostosis) between the radius and ulna. In dogs, these deformities typically occur in one or both front legs, although occasionally
Angular limb deformities typically become noticeable about 3 to 4 weeks after some sort of trauma to the affected leg. Owners usually bring their dog to the veterinarian not because of the traumatic event, but instead when they begin to notice deformity of the affected limb.Clinical signs of angular limb deformities include one or more of the following:These signs become increasingly obvious over time.Angular limb deformities – especially those caused by premature closure of one
Angular limb deformities typically are obvious to owners once they begin to develop. The underlying cause of the abnormality usually is trauma, which probably occurred several weeks before signs of the deformity become apparent.Diagnosis of angular limb deformities is best made based upon history, clinical presentation and radiographs (X-rays). Radiographs of both front legs (even if only one is affected), from the shoulder joints all the way down to the toes and from several different
The goals of treating angular limb deformities are to prevent or correct the bone and joint abnormalities, reduce the dog’s discomfort and maintain as much leg length as possible.The most commonly reported treatment for an angular limb deformity, caused by premature closure of a distal ulnar growth plate or otherwise, is surgical correction. The particular surgical approach will depend upon the age of the animal (whether its growth plates are still growing or are already
