ASSESSMENT AND TREATMENT OF EQUINE HUMERAL FRACTURES - RETROSPECTIVE STUDY OF 54 CASES (1972-1990)

Fractures of the humerus were diagnosed in horses at The Ohio State University Veterinary Teaching Hospital. Twenty-four horses (44.4%) were destroyed after radiographic assessment (mean age of 5.0 years). Surgical treatment was elected in 13 horses (24.1%, mean age of 0.42 years). Conservative management, consisting of prolonged stall rest, was chosen for 17 horses (31.5%, mean age of 2.2 years). In the surgically treated group, 3 foals (23.1%) all less than 2 months of age at the time of fracture and treated with intramedullary stack pinning, survived and became athletically sound. After conservative treatment, 9 (52.9%) horses were considered successful, 4 becoming athletically sound and 5 becoming pasture sound. The mean age at the time of presentation in the 9 horses considered successful was 1.81 years. With current fixation techniques, conservative management of equine humeral fractures appears to be as good an option as surgical treatment.
