Use of the novel ANSPACH bone collector for bone autograft in anterior cervical discectomy and cage fusion

The use of interbody cages with bone autograft following anterior cervical discectomy is well documented. The use of high-speed drills in the drilling of the posterior osteophyte results in the production of bone dust with viable osteophytes. We report the use of the ANSPACH bone collector device, which can be connected to standard suction circuitry and used to collect this bone dust. A group of six patients undergoing anterior cervical discectomies at one (4) or two levels (2). The bone collector was attached to the suction system. Following collection of the desired bone dust from the devices' collection chambers, it was fitted into the previously sized interbody cages and impacted into the disc spaces. The bone collector is a single-use, disposable device, delivered sterile, designed to connect to standard 6-mm suction tubing. The use of the bone collector provided sufficient bone material for complete filling of the interbody cages in all of the patients. The use of autogenous cancellous bone material is the gold standard with regards to bone graft. The collection of bone dust during the use of high-speed drills has a number of applications and could provide a useful source of viable osteogenic material in spinal, cranial and craniofacial procedures. The use of the ANSPACH bone collector incorporated into a standard suction system provides an efficient method of autograft collection, removing the need for an adjunctive procedure with associated donor-site morbidity.
