The purpose of our study was to evaluate the temporal aspect of the onset of the outcome of a triple pelvic osteotomy (TPO) in a group of 34 dogs younger (but one) than 12 months of age with a homogenous longer follow-up. In each case, lameness and positive Ortolani sign were detected. In some cases, bilateral TPO or denervation of the contralateral hip was performed. Clinical and radiological re-checks were performed in a uniform way for all dogs one and three months after surgery. The mean angle of reduction and subluxation for the operated joints decreased substantially by 17.3 ±1.58 degrees one month after the surgery, without any further statistically significant reduction at three months. Additionally , in 71% of the operated joints, the outcome of the TPO, defined in terms of the absence of the angle of reduction and subluxation, was already established at one month post-surgery and did not change at three months post-surgery. These results indicate that the outcome of the TPO in dogs is established within a month after the surgery and is basically maintained afterwards.
The aim of this paper was to assess the effectiveness of treatment of Type I (according to Hansen) intervertebral disc extrusion using the fenestration method. The evaluated clinical material included 37 chondrodystrophic dogs in which multiple fenestration (from 2 to 6 intervertebral spaces) was performed. Dachshunds comprised 86.5% of patients. All dogs were administered corticosteroids during the operation. A mass similar to a slightly jelly-like yogurt, cottage cheese or plaster-like consistency was extracted. In one case a post-surgical pyogenic infection of the wound occured. In two cases, a deterioration in the neurological state followed the fenestration procedure of the cervical spine. In one case of thoraco-lumbar spine fenestration, a deterioration of clinical state was found. Recovery was observed after disc extrusion from the cervical spine in 8 out of 11 dogs, from the thoraco-lumbar spine in 12 out of 14 dogs with the 2nd grade clinical signs and in 11 out of 12 dogs with the 3nd grade clinical sings. In 6 dogs, recurrence of first or second grade clinical signs occurred, but only half of them had to undergo treatment. The probability of dog recovery did not depend on the degree of symptom intensity in a statistically significant way (p=0.11) or on the duration of the disease before the surgical treatment (p=0.87).
The aim of the publication is to assess the effectiveness of the treatment of type I disc extrusion according to Hansen by using the method of hemilaminectomy without fenestration. The evaluated clinical material comprised 36 chondrodystrophic dogs in which 38 surgical procedures were performed. All dogs were administered corticosteroid during the operation. Dachshunds made up to 79% of patients. In 34 cases grainy mass was extracted from the vertebral canal. In two cases it was plaster-like mass and in other two - granulo-chondral. Most often (12 cases) the prolapse of the nucleus pulposus was observed between the first and second lumbar vertebra. There was one case of the postoperative pyogenic infection of the wound. Recovery was observed in all dogs with 3rd grade clinical signs, 1] out of 18 dogs with 4th grade and 8 out of 13 dogs with 5lh grade of dysfunction severity. The recovery time of the dog depended in the statistically significant way on the severity of symptoms and the grade of the present disease (p<0.00005). There did not appear to be any statistically significat relationship between the recovery time and the duration of symptoms pre operatively (p=0.42), the time of non-ambulatory status (p=0.27) and the breed of the dog (p=0.81).
