Summary

Medical records of 31 dogs that had undergone surgery for correction of intussusception during a 14-year period were reviewed. Enteroplication was performed on 9 dogs during the initial surgery, and intussusception did not recur in any of these dogs. Intussusceptions recurred in 6 of 22 dogs without enteroplication. Five of these dogs had undergone resection of the primary lesion and anastomosis and 1 dog had undergone manual reduction of the intussusception. Intussusceptions recurred proximal to the initial lesion in 4 dogs, and at the same site in 2 dogs. Enteroplication was performed in 4 dogs following surgical correction of recurrence of an intussusception, and further recurrences were not seen in any of these dogs. Enteroplication did not cause any apparent adverse effects and decreased the probability of recurrence of intussusception in these dogs.

Objective

To evaluate effects of shelf arthroplasty on coxofemoral joint laxity and progression of degenerative joint disease in young dogs with hip dysplasia.

Design

Prospective, controlled study.

Animals

10 dogs between 10 and 24 months old and weighing between 20 and 27 kg. All dogs had bilateral coxofemoral joint laxity (ie, an Ortolani's sign).

Procedure

In all dogs, shelf arthroplasty was performed on the right coxofemoral joints, and a sham procedure was performed on the left. Dogs were evaluated before and after surgery by means of lameness assessment, coxofemoral joint palpation and goniometry, thigh circumference measurement, and radiography.

Results

There were no significant changes in coxofemoral joint mobility, range of motion, joint laxity, degree of degenerative joint disease, or thigh circumference during the study. A greater amount of periacetabular bone formed on the right side than on the left side; however, dogs did not develop large bony shelves, and the amount of periarticular bone decreased over time. The polymer implants remained in their original position and were encapsulated by fibrous tissue. There was no histologic evidence of osteoconduction by the implants.

Clinical Implications

The polymer implants used in this procedure do not appear to be osteoinductive. Shelf arthroplasty was associated with minimal morbidity and was not associated with serious adverse sequelae in this study, but the procedure did not alter the progression of hip dysplasia in these dogs. We cannot advocate shelf arthroplasty using this polymer as a treatment for dogs with hip dysplasia. (J Am Vet Med Assoc 1996;208: 1838-1845)
