Correcting angular limb deformities of radius-ulna and tibia in nine dogs using computer-assisted spider frame system

In this study, angular deformities in 9 dogs, including 8 antebrachium and 1 tibia, were corrected using hexapod external fixators with the help of the computer-aided Spider Frame system.Preoperative planning included measurement of craniocaudal and mediolateral angular deformities, rotational deformity, length deficit, as well as determination of the source of the deformity and assembly of the frame.Joint lines and osteotomy/ostectomy lines were determined according to CORA points determined during preoperative measurements. Proximal and distal rings were placed. After the installation of the spider, radial/ tibial osteotomy/ostectomy was performed at the CORA point of the radius/tibia. After the operation, craniocaudal and mediolateral radiographs were taken in all cases. Ring dimensions, angular deformity values (including angulation, translation and rotation) and the degree of shortening were evaluated by radiographs. These data were entered into the web-based Spider software to generate correction prescriptions, after which the length and deformity correction process started on postoperative days 3-5. Functional results were excellent in seven cases and good in the other two cases. Long-term cosmesis was good to excellent in all cases.In conclusion, Spider Frame is a new generation external fixator system with many technical advantages and we recommend its use in appropriate cases

Herniation of Urinary Bladder into Vaginal Tunic through Inguinal Ring in a Male Persian Cat

A 10-year-old male Persian cat was referred to Department of Surgery, Small Animals Clinic, Istanbul University-Cerrahpasa, Faculty of Veterinary Medicine, with the complaint of swelling under the abdomen. Micturition was normal and there was no blood, smell, or color change in the urine. In the clinical examination, swelling was detected in the inguinal region. The content of swelling was determined by a puncture biopsy in the urine. In the direct latero-lateral abdominal radiography, the bladder was visualized outside the abdominal cavity. Considering the first clinical and radiological findings indicating the presence of an inguinal hernia, operative treatment was planned. During the operation, the bladder was determined to be loca-ted in the cranial within the tunica vaginalis, and the right cryptorchidic testis was located immediately adjacent to the apex of the urinary bladder. After cryptorchidic testes were removed, the urinary bladder was reduced into the abdominal cavity through the right inguinal ring
