ABSTRACT:
The invention is directed to an adjustable mold for use in fabricating bigradable polymeric bone replacements or implants. The invention consists of a box-like structure with two movable plates therein which can be locked into place permitting different size replacements to be fabricated. The interior walls are panels consisting of polytetrafluoroethylene which permit easy removal of a cured bone replacement. The construction and locking means for the movable plates permit the invention to withstand the pressures developed in replacement fabrication as well as to withstand the most commonly used types of sterilization procedures.
