The high quality cancellous bone extraction set can be used for percutaneous harvesting of cylindrical bone marrow from the iliac/ pelvic crest with a minimally invasive technique. The cancellous bone extraction set was developed in conjunction with Dr. med. Heinrich Böhm, Orthopaedist, Zentralklinik Bad Berka. This technology is used, if smaller quantities of non structural grafts for reconstruction therapy at the skeleton are needed. It can be used in neurosurgical, orthopaedic or cranio- maxillo-facial procedures.
