ABSTRACT

We clinically used a new surgical instrument, BoneHOG™, which has been used in the United States, to harvest particulate cancellous bone and marrow (PCBM) from the ilium. Surgery was less invasive with this instrument than with previously used methods. The instrument was used in 10 patients with alveolar cleft who underwent bone graft surgery. The amount of harvested PCBM ranged from 2.5 g to 8.0 g, with an average of 5.2 g. The time required for PCMB collection ranged from 40 to 69 min, with an average of 51 min. The visual analog scale (VAS) score (maximum score, 10) of iliac site pain at rest was assessed after surgery. The average VAS score of the 10 patients was 2.7 on the night of surgery, 2.9 on postoperative (p.o.) day 1, 0.8 on the p.o. day 7, and 0.1 on p.o. day 30. Harvesting PCBM with BoneHOG™ had some advantages: the length of the skin incision at the iliac site was less than 2 cm, and neither a bone saw nor an electric engine bar was necessary. The procedure, including bone scraping, harvesting, and collecting, could be completed in a relatively short time. Not everyone can easily and safely collect bone with the use of BoneHOG™. We consider experience and training in bone collection using BoneHOG™ necessary to complete the procedure safely. Key words: particulate cancellous bone and marrow, bone graft, alveolar cleft, ilium
