Description
Between 1990 and 1993 ten cows with diaphyseal sequestration of the metacarpal or metatarsal bone were brought to the Clinic for Food Animals and Horses, University of Bern. History, clinical and radiographic findings at admission, therapy, and clinical and radiographic short- and longterm results were evaluated retrospectively. Six animals had a history of trauma. The metatarsal bone (n = 9) was much more frequently affected than the metacarpal bone (n = 1). Lameness was slight in seven cases and intermediate in three cases. Soft tissue swelling was present in all cases, and fistula formation in eight cases. Sequestrectomy was performed in nine cases, the exuberant new bone circumferentially removed in three of these cases, and the skin primarily closed in all nine cases treated surgically. One animal with a small sequestrum, showing no fistula formation, was treated conservatively. Four to 44 months after surgery, interviews with the owners by telephone revealed that the recovery had been satisfactory in all ten cases. At the same time period, clinical and radiographic examinations of the six animals that were still alive were performed by a veterinarian additionally. Normal limb function had been restored in all six animals, although the affected limb was clearly distinctable from the unaffected contralateral limb, because of its increased diameter. From the results of this study we concluded that longterm prognosis after sequestrectomy is favourable; primary wound closure can be attempted with good success. Cosmetically promising results, however, can only be achieved, if sequestrectomy is performed early enough in the course of the disease or if the exuberant new bone is surgically removed
