Equine bone core biopsy: evaluation of collection sites using a new electric drilling machine.

摘要

The use of a new bovine biopsy set to obtain corticocanellous bone core at different sampling sites (rib, sternum, tuber coxae) in the horse was evaluated. Bone biopsies were made in 3 tranquilized standing horses and PM in 8 horses. The electric drill used provided a 4 mm bone core biopsy of a maximum length of 28 mm. When used in tranquilized horses with local anaesthesia, handling of the biopsy drill was easy and the procedure was safe for both the animal and the operator. The tuber coxae was the most convenient sampling site from which a bone biopsy was obtained in all animals; 1 sternal and 2 rib biopsies could not be taken in 2 obese animals. Sternal biopsy is recommended for haematopoietic bone marrow evaluation. Cortical bone was present in greater quantities in the ribs, but 1 rib fractured after sampling. Cancellous bone was better preserved in the tuber coxae and sternum.
