BIOLOGICALLY ACTIVE IMPLANTS

摘要

The invention relates to an implant for providing pathological modifications on the spinal column and/or locomotor system. According to the invention, th e implant comprises an enamel-type coating which has a thickness of 100 .mu.m or less and which is made of a biodegradable polymer such as polyactide. This coating has an osteoinductive effect and thus an effect which promotes the healing of fractures. Additional osteoinductive materials such as growth factors can be incorporated in the coating. The invention also relates to a method for producing such an implant using the follow steps: Producing a dispersion of biodegradable polymers in an organic solvent; applying the dispersion to the surface to be coated; evaporating the solvent off.
