To report on a series of 4 horses with supraglenoid tubercle fractures repaired with locking compression plates.

Study Design:

Case series.


Four horses ranging in age from 6 weeks to 20 months and weighing from 121 to 425 kg with supraglenoid tubercle fractures of 1 day to 6 weeks in duration.


Supraglenoid tubercle fractures were reduced and stabilized with transversely positioned locking compression plate(s) with and without additional tension band wiring.


All fractures reached bony union. Two postoperative surgical site infections were managed with drainage and antibiotherapy. Three of the 4 horses continued onto athletic careers including flat racing, dressage, and hunter/jumper competition. The remaining horse was lame for a prolonged period, but was sound at 4 years.


The application of one or two, transversely positioned LCPs should be considered for the repair of SGT fractures because of the relative ease of the technique, and its elimination of a biceps brachii tenotomy. All screws can be inserted in a lateral to medial direction without transection or drill penetration of the biceps brachii tendon.

Clinical Relevance:

SGT fractures of various durations can be repaired in a wide range of horses with transversely positioned LCPs, and allow return to athletic function.
