Cancellous bone model

bonejointorthopedic surgery

SYNBONE’s anatomical models are manufactured with a specially formulated polyurethane foam comprising of a cancellous inner core and a harder outer shell simulating the cortical bone. They are primarily developed for orthopaedic surgical education and are designed to provide the feeling of working with humanlike bone. Similar forces are required to saw, tap, plate and drill our models. Although the SYNBONE’s do not have the same biomechanical properties of natural bone, which is stronger than the SYNBONES due to its complex composition, the feedback is very positive from a number of biomechanical testing facilities that have compared our bone models with real bones. During ballistic testings SYNBONE’s fracture in a manner very similar to natural bones providing an excellent reproducible simulation. SYNBONES provide the excellent mechanical properties of natural bone. A cortical layer and an inner foam structure are representing the cancellous bone in this example with a an intramedullary canal. Soft cancellous bone is used in models designed for total joint replacements and internal fixation on long bones. Mechanical Properties The handling properties of SYNBONE closely simulate those of real bones and are achieved by complex design, moulding and production techniques. They can be cut, drilled, tapped and modified by all available orthopaedic instruments. Medium cancellous bone can be used for the same applications as the soft cancellous bone as well as for external fixation and reference mark pinning. Hard cancellous bone is mainly used for external fixation.
