초록

A 6-year-old Thoroughbred mare presented to the Korea Racing Authority Equine Hospital with dropping of the left front fetlock due to an injury sustained while racing. Radiographic examination revealed a comminuted fracture of both proximal sesamoid bones of the affected fetlock. Arthrodesis of the fetlock joint using a broad dynamic compression plate with a tension band wire was performed as a salvage procedure for the future use as a broodmare. After surgery, however, a delayed union of the bones and surgical site infection was present for a prolonged period. Staphylococcus aureus was persistently identified from the surgical site, and antimicrobial therapies were based on antibiotic sensitivity tests, including regional perfusions. The removal and replacement of surgical implants associated with seropurulent discharge was based on coordinating the development of fetlock ankylosis and infection control over 13 months. Firstly, seven screws associated with surgical drainage were replaced and bone morphogenetic protein-2 (BMP-2) and local antibiotics were placed into the surgical site to accelerate bone fusion at postoperative month 7. Further six screws, along with drainage, were removed at postoperative month 10. The plate and screws were removed from the limb due to the progression of bone fusion at postoperative month 13; BMP-2 and local antibiotics were also used. Delayed healing of arthrodesis due to surgical site infection and implant instability were treated by implant removals and antibiotic therapies, and the horse eventually showed improved weight-bearing ability of the affected limb.
