An orthopedic implant is formed from a sheet of moldable material such as a polymer or a bioresorbable material using an instrument. The material is heated above its glass transition temperature so that it can be formed into the desired shape of the implant. Then the material is cooled below its glass transition temperature to harden the material such that it retains the implant shape. During surgery, a surgeon can form implants to fit unique orthopedic applications by using instruments having various internal and external mold forms between which the sheet of moldable material can be rolled, wound, pressed or drawn. |
