Fracture of the greater tubercle of the humerus in a filly.

The study presents a case of a young Thoroughbred horse which experienced a fracture in the greater tubercle of the humerus, but made a full recovery after rest and rehabilitation. The horse was able to return to training and racing without showing signs of lameness.

Case study of a Filly with Humerus Fracture

• The focus of the research centers around a rare fracture in a 16-month-old Thoroughbred filly. Specifically, a fracture of the caudal (rearward) portion of the greater tubercle (a large outward-extending area) of the humerus (the part of the foreleg connecting the shoulder with the elbow).
• The onset of this fracture caused significant impairment in movement, resulting in severe lameness.

Diagnosis Process

• In identifying the nature of the injury, the researchers performed radiography on the filly’s affected shoulder. This imaging revealed the precise location and characteristics of the fracture.
• The fracture was discovered to be extra-articular, meaning it did not involve the horse’s joint directly. A beneficial observation was the presence of a surrounding bony callus – a sign of new bone formation in response to the fracture.
• No signs of joint disease were found, which indicated the fracture was a standalone issue and not part of a broader health concern.

Rest and Rehabilitation

• To facilitate recovery, the filly was given a period of 5 weeks rest in a stall. Further aiding the healing process, the horse was then given an extended recovery duration of 11 months in a pasture, which would provide a less stressful environment.

Return to Active Duty

• Following this lengthy recuperation process, the filly was able to be trained and raced again. Importantly, it did not display any signs of lameness, indicating a successful full recovery from the fracture and effective rehabilitation process. The return to racing also evidenced the filly’s restored physical condition and strength.

In conclusion, the case study highlights successful diagnosis, rest and rehabilitation strategies for dealing with a rare humerus fracture in horses. It underscores the importance of thorough assessment and tailored recovery plans in returning equine patients to their normal, active states.
