Computed tomographic re-evaluation of skeletally immature French bulldogs previously diagnosed with humeral intracondylar fissure: 12 cases (2018-2022).

ABSTRACT

OBJECTIVES: The objective of this study was to present the follow-up findings obtained through computed tomography in skeletally immature French bulldogs previously diagnosed with humeral intracondylar fissures. MATERIALS AND METHODS: Medical records from a surgical referral centre between January 2018 and September 2022 were evaluated for all dogs with a humeral condylar fracture where preoperative CT of both humeri was performed. French bulldogs between the age of 12 weeks and 12 months were identified and evaluated for the presence of contralateral humeral intracondylar fissure. The dogs with follow-up CT were evaluated for humeral intracondylar fissure resolution. RESULTS: A total of 137 humeral condylar fractures were operated on within the study period, 58 of which were in French bulldogs. Twenty-seven French bulldogs had a contralateral humeral intracondylar fissure with 12 dogs matching the inclusion criteria. Follow-up CT demonstrated resolution of the humeral intracondylar fissure in 11 (91.7%) of 12 cases. CLINICAL SIGNIFICANCE: Contralateral humeral intracondylar fissures are common in skeletally immature French bulldogs sustaining humeral condylar fractures and the majority of these fissures tend to fuse within the follow-up period. Due to the potential for breed variation in ossification of the humeral condyle, follow-up CT may be warranted in skeletally immature French bulldogs before considering prophylactic transcondylar screw placement.
