Objective— To describe a method for internal fixation of supraglenoid tubercle fractures in conjunction with complete tenotomy of the biceps brachii tendon.
Animals— Three horses, ranging in age from 8 months to 2 years and weighing from 300 to 400 kg.
Methods— Fractures were repaired by open reduction-internal fixation using bone screws placed in lag fashion and complete tenotomy of the biceps brachii tendon.
Outcome— All three horses were sound for their intended use with a good cosmetic result 6 months after surgery.
Conclusions— Complete transection of the biceps brachii tendon facilitates supraglenoid tubercle fracture repair by reducing tensile forces exerted on the supraglenoid tubercle. Complete tenotomy does not appear to preclude return to a successful athletic career.
