摘要：
Systems for bone fracture repair are disclosed. One disclosed system includes a biocompatible putty that, when packed in/around a compound bone . fracture, provides full load-bearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration. The disclosed putties degrade over time to harmless resorbable by-products as normal bone regenerates. Fixation devices for contacting an endosteal wall of an intramedullary (IM) canal of a fractured bone are also disclosed. One such fixation device includes a woven elongated structure fabricated from a resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven structure to be radially compressed, placed in an insertion tube and delivered to the IM canal using the insertion tube. When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is coated with or filled with a resorbable polymer resin that cures in situ, or in the IM canal.
