A 7‐year 9‐month‐old, neutered, male British shorthair cat was referred for chronic regurgitation and vomiting. Previous symptomatic medical management did not improve these clinical signs. Survey radiographs and abdominal ultrasound revealed no significant abnormalities of the gastrointestinal tract. Exploratory laparotomy was performed to obtain gastrointestinal biopsies. Sliding hiatal hernia and an abnormal gastric outpouching at the fundus, measuring 15 × 15 × 15 mm, were identified. Surgical treatment of the hiatal hernia included phrenoplasty, oesophagopexy and left‐sided gastropexy. Additionally, the gastric outpouching was resected. Histopathologic examination of the excised fundic tissue revealed findings consistent with those indicative of a false gastric diverticulum. Postoperative examinations on Days 5 and 10 and telephone follow‐up on Days 30 and 120 revealed a marked reduction in clinical signs. The combination of surgical techniques—phrenoplasty, left‐sided gastropexy, oesophagopexy and gastric diverticulum resection—was found to effectively improve the cat's clinical signs.
To determine the biomechanical behavior of different plate systems used for oblique ilial fracture fixation in cats. Study design: Ex vivo biomechanical study. Sample population: Fifty fresh-frozen feline hemipelvises. Methods: Standardized simple oblique ilial fractures were created and fixed via lateral plating, using different implant systems (10 fractures in each group) The systems were: (1) the Advanced Locking Plate System (ALPS-5); (2) the Advanced Locking Plate System (ALPS-6.5); (3) the Locking Compression Plate 2.0 (LCP);(4) the FIXIN 1.9-2.5 Series (FIXIN), and (5) the Dynamic Compression Plate 2.0 (DCP). Stepwise sinusoidal cyclic loading was applied until failure (10-mm displacement). The groups were compared with regard to construct stiffness and the number of cycles withstood before 1-, 2-, 5-, and 10-mm displacement. Results: Bending stiffness was lower in ALPS-5 than in other specimens (P < .05). The ALPS-6.5 specimens withstood more cycles (P < .05) before 2-, 5-, and 10-mm displacement than the ALPS-5 and DCP specimens . The LCP and FIXIN specimens endured more cycles than DCP specimens before displaying 5-and 10-mm displacement (P < .05). The ALPS-6.5, FIXIN, and LCP specimens endured higher loads before failure than the DCP specimens (P < .05). Screw loosening occurred in all nonlocking specimens, and bone slicing occurred in all locking specimens.
Conclusion:The DCP and ALPS-5 constructs are less resistant to cyclic loading. Failure in nonlocking specimens involved screw loosening. It involved bone slicing in locking specimens.Clinical significance: Both the plate size and the plate-screw interface are key to lateral plating success in cases of feline ilial fractures. The use of locking plates reduces the risk of the screw loosening in such cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
