Initial Experience with BoneBac Press TM : A Novel Autologous Bone Graft Harvesting and Collecting Device

Object: The objective of this study is to analyze the utility of a novel autologous bone graft harvesting and collecting device in spinal fusion surgeries. Methods: 35 patients underwent fusion procedures in the cervical or lumbar spine using the BoneBac PressTM. Procedures included anterior cervical discectomy with fusion (ACDF), lumbar laminectomy and posterolateral arthrodesis, and transforaminal lumbar interbody fusion (TLIF). The amount of bone graft collected from each level was determined as well as the need for additional bone graft extenders. Fusion rates were determined based on an independent radiographic evaluation performed 5 to 12 months postoperatively. Results: 54 total levels were operated upon, collecting a total of 176.0 cc of autograft. The average amount of bone collected was 3.26 cc/level. In the cervical and lumbar spine the average amount of bone collected per level was 2.30 cc and 6.77 cc respectively. The fusion rate was 94.3% at 10 months postoperatively. In most cases no additional bone graft extender was needed. Autologous bone collected had excellent handling characteristics and was easily packed into cages or placed posterolaterally. Conclusions: The use of autograft bone material collected using the BoneBac PressTM is costeffective, significantly reduces bone graft cost, and eliminates donor graft site morbidity while promoting successful fusion.
