Treatment of olecranon bursitis in horses: 10 cases (1986-1993).

Medical records of 10 horses with olecranon bursitis were reviewed to examine treatments, evaluate a technique for en bloc resection of the bursa in standing horses, and determine outcome of the horses after treatment. Before admission, 6 horses had been treated by needle aspiration of fluid from the mass, followed by injection of corticosteroids. Subsequent treatment for 2 of these 6 horses included open drainage and packing of the cavity with gauze soaked in 7% iodine solution. None resolved after these treatments. After admission to the hospital, 5 horses were treated medically and 5 were treated by en bloc resection of the bursa. One horse that had received intralesional injection of a radionuclide was lost to follow-up evaluation. One horse treated conservatively by open drainage and packing and 1 treated by injection of a radionuclide had resolution of the olecranon bursitis. Only 1 of these 2 horses had a cosmetic result. The acquired bursae decreased in size in 2 horses (1 treated with a corticosteroid and 1 with orgotein), but were still visible 7 and 46 months after treatment, respectively. The surgery site of 4 horses that were treated by en bloc resection healed by primary intention, and the owners of these horses were pleased with the cosmetic results. The suture line of 1 horse dehisced 5 days after surgery. Proliferative granulation tissue was removed on 2 occasions, and the site healed by second intention after 2 months. A small knot and some white hair remained at the surgery site.
