Retrospective study of success rate of arthroplasty ofhip joint in dog

Hip joint insuffciency (loss of function as a joint to transfer force) follows some causes as in congenital and traumatic conditions. Clinical signs depend on severity of joint involvement and degenerative changes. The aim of this retrospective study was to determine and compare success rate of hip arthroplasty in referral toy and large breed dogs for 4 years. Eighty-four dogs with toy and large breed dogs less than one year old have been referred to small animal clinic with lameness, pain and loss of function on hind limb. Radiograph survey was prformed and revealed various changes in hip joint. Conservative and surgical treatments were carried out and followed up during two years period. All dogs tolerated head and neck resection of femur. In congenital cases, weight was not a determinant factor and there was not signifcant difference between DJD and outcome statistically, but in all congenital and traumatic cases less than one year old there was not a signifcant difference between DJD and outcome in less than 10 Kg and was statistically signifcant in dogs more than 10 kg. In our study we found that, weight and etiology were not effective factors on success rate.
