Abstract | Systems for bone fracture repair are disclosed. One system includes a biocompatible putty that may be packed about a bone fracture to provide full loadbearing capabilities within days. The disclosed putties create an osteoconductive scaffold for bone regeneration and degrade over time to harmless 5 resorbable byproducts. 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 resorbable polymer filaments. The woven elongated structure has resilient properties that allow the woven 10 structure to be radially compressed and delivered to the IM canal using an 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 impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.
Cette invention concerne des systèmes pour la réduction des fractures osseuses. Un de ces systèmes comprend un mastic biocompatible qui peut être tassé autour d'une fracture osseuse pour lui conférer des capacités de support de charge en l'espace de quelques jours. Les mastics décrits créent une structure ostéoconductrice pour la régénération de l'os qui se dégrade dans le temps en sous-produits résorbables inoffensifs 5. Des dispositifs de fixation destinés à être placés au contact d'une paroi endostéale du canal intramédullaire (IM) d'un os fracturé sont également décrits. Un de ces dispositifs de fixation comprend une structure tissée 10 de forme allongée à base de filaments de polymère résorbables. La structure tissée de forme allongée possède des propriétés élastiques qui lui permettent d'être comprimée radialement et positionnée dans le canal IM au moyen d'un tube d'insertion. Quand le tube d'insertion est retiré, la structure tissée se relâche dans le sens de sa largeur pour venir au contact de la paroi endostéale. La structure tissée de forme allongée est imprégnée avec une résine polymère résorbable qui durcit in situ, ou dans le canal IM. |
