Supraglenoid tubercle fractures repair with transverse locking compression plates in 4 horses.

The research article discusses a study where supraglenoid tubercle fractures in horses were treated using transverse locking compression plates. The study found this method successful, with all cases achieving bony union, and most of the horses returning to athletic functionality.

Study Details

• The study reported on a series of four horses with supraglenoid tubercle fractures. These horses ranged in age from six weeks to 20 months old and weighed between 121 kg and 425 kg.
• The fractures being treated had been sustained one day to six weeks before the treatment.
• The fractures were reduced and stabilized using transversely positioned locking compression plates, sometimes alongside additional tension band wiring.

Results

• All treated fractures achieved bony union, meaning the breaks in the bone had successfully healed.
• Two of the surgical sites got infected post-operation, which were managed with the application of drainage and antibiotherapy. Despite these minor complications, successful recovery was achieved.
• Three of the four horses were able to return to their athletic careers post-treatment, participating in activities including flat racing, dressage, and hunter/jumper competition. The remaining horse experienced prolonged lameness, however, it was sound by the fourth year post-operation.

Conclusions

• The technique of applying one or two transversely positioned locking compression plates (LCPs) is recommended for the repair of supraglenoid tubercle (SGT) fractures due to the relative ease of the technique. This method also avoids the need for a biceps brachii tenotomy, an operation that involves cutting this tendon.
• All screws can be inserted in a lateral to medial direction without transecting or penetrating the biceps brachii tendon with a drill.
• SGT fractures of varying durations can be repaired in a broad range of horses with transversely positioned LCPs, allowing these animals to potentially return to their athletic functions.
