Polymer filled implant

摘要

An orthopaedic implant (10) includes a flexible bag (28) having at least a portion thereof which is expandable under pressure; and a polymer within the bag (28). The orthopaedic implant (10) is implanted within a bone (12) by forming a cavity (22) in the bone (12), inserting a flexible bag (28) into the cavity (22), the flexible bag (28) having at least a portion (32) thereof which is expandable under pressure; pressure filling the bag (28) with a polymer, whereby the expandable portion (32) of the bag (28) expands to substantially entirely fill the cavity (22) in the bone (12), and hardening the polymer.
