Clinical experience and outcomes using a commercially available micro-plating system for metabone fractures in dogs and cats: 10 cases (2019-2023).

Abstract

OBJECTIVES: To report the clinical experience and long-term outcome following metabone fracture stabilisation using a commercially available micro-plating system (VetKISS, 1.0-mm, IMEX Veterinary, USA). MATERIALS AND METHODS: Consecutive, client-owned cats and dogs weighing <7&#x2009;kg, with traumatic metabone fractures stabilised using VetKISS micro-plates were prospectively enrolled with informed owner consent. Clinical and radiographic parameters were recorded. Either short-term or long-term clinical and radiographic follow-up was required for study inclusion. RESULTS: Four cats and six dogs were enrolled and operated by one of two board-certified surgeons. Bodyweight ranged from 1.9 to 6.6&#x2009;kg. Number of metabones fractured: all four (60%), three (30%) and two (10%). Anatomical alignment was restored for each metabone. External coaptation was not used in any case. Radiographic follow-up documented clinical or bony union in all cases. Mean time to clinical union was 51&#x2009;days. One major complication (screw removal) and two minor complications (partial construct failure) were observed. All patients made a complete functional recovery at the time of documented union. Long-term follow-up was available in five cases. No lameness (evaluated independently by both surgeons) or plate sensitivity was noted. CLINICAL SIGNIFICANCE: This is the first clinical evaluation of the VetKISS for metabone fracture repair, and includes long-term follow-up. Results demonstrated complete functional recovery and 100% clinical union rates in all patients, with acceptable complication rates. This system can be considered for metabone repair in patients weighing <7&#x2009;kg without the use of external coaptation.
