Spontaneous Resolution of a Humeral Intracondylar Fissure in a Skeletally Immature French Bulldog

Abstract A 4-month-old male entire French bulldog was presented for the investigation of acute left thoracic limb lameness. Computed tomography (CT) revealed a right-sided humeral intracondylar fissure (HIF) and a left-sided medial humeral condylar fracture which was managed by open reduction and internal fixation. Follow-up CT at 36 days after surgery revealed healing of the condylar fracture and partial resolution of the HIF, which was radiographically unapparent on further CT images 105 days thereafter (at 220 days of life). To the best of the authors' knowledge, this is the first reported case of spontaneous resolution of a HIF beyond the normal age of reported humeral condyle ossification center closure.
