METHOD AND DEVICE FOR PRODUCING TEMPORARY KNEE JOINT SPACERS WITH STEMS OF VARIOUS SIZES

摘要

A cement mold assembly configured to form a temporary implant for use in delivering antibiotics to an infected site can includes a first mold (512) and a second mold (514). The first mold can have an open end and an inner wall. The first mold can define a tibial component forming cavity including a platform forming cavity (532) and a stem forming cavity (534). The second mold can have a body portion configured to be slidably and progressively receivable by the inner wall into the tibial component forming cavity in a direction toward the closed end. Progressive advancement of the second mold into the tibial component forming cavity allows a surgeon to select a desired thickness of the spacer. A femoral mold component assembly and a separate intramedullary canal filling component mold assembly, can be flexible so that it can be bent during curing to match an x-ray of a specific individual.
