Complete biceps brachii tenotomy to facilitate internal fixation of supraglenoid tubercle fractures in three horses.

The research discusses a method to repair supraglenoid tubercle fractures in horses through a complete cut of the biceps brachii tendon, noting that this approach does not prevent the animal from returning to an athletic career.

Objective and Methodology

• This study aimed to describe a method for repairing supraglenoid tubercle fractures (a roundish projection on the superior part of the scapula, which serves as a ‘groove’ or attachment point for tendons) in horses.
• A specific focus was on the benefit of using a complete tenotomy of the biceps brachii tendon (TRT). This is a complete severing of the tendon from the bone.
• Three horses were included in this research, and their ages varied from 8 months to 2 years and weighing between 300 to 400 kg.
• The fracture repair was performed using open reduction-internal fixation (ORIF). This surgical technique involves opening the site of the fracture, setting the bone in correct alignment, and fixing it in place with bone screws placed in a lag fashion.

Results

• All three horses regained soundness appropriate for their intended use, such as potential racing or work, and showed good cosmetic results 6 months after surgery.
• The results indicated that a tenotomy did not preclude the horses from returning to a successful athletic career.

Conclusion

• The conclusion draws on the experimental evidence from the three horses, suggesting that a full cut of the biceps brachii tendon can help in the repair of supraglenoid tubercle fractures.
• This is suggested to be mostly due to the reduced tensile forces exerted on the supraglenoid tubercle. By completely severing the biceps brachii tendon, the tension pulling on the fracture point is reduced, which seemingly aids in the healing process.
• The overall outcome indicates a successful return to an athletic career for horses post-procedure, demonstrating the practical application and potential benefits of this procedure.
