Compositions and methods for treating bone fractures

A method of treating, stabilizing, or preventing a bone fracture or strengthening a bone, comprising:

• a. making at least a first hole and a second hole through said bone by drilling or laparoscopy;
• wherein a first of said holes is placed on a proximal side of said bone fracture and a second of said holes is on a distal side of said bone fracture;
• b. inserting a fiber tube in said first hole, wherein said inserting said fiber tube comprises the steps of:
• i. inserting said fiber tube in said first of said holes, and
• ii. drawing said fiber tube via a lead wire that exits said second of said holes;
• wherein said fiber tube is placed between said first and second holes;
• wherein said fiber tube comprises one or more surface modifications selected from the group consisting of electrochemical, chemical, thermal, discharge plasma, and radiation treatment;
• wherein said fiber tube is pre-impregnated with a resin system at a temperature below the physiological temperature and resin system polymerizes at physiological temperature after insertion of said fiber tube in said bone;
• wherein said fiber tube is removable;
• wherein said fiber tube is configured to resist compressive, torsional, and shear forces when placed in a bone, conforms to the shape of a bone cavity in said bone, and is configured to retain tube shape after placement in said bone;
• and
• c. filling said fiber tube, said first hole, and said second hole with a biocompatible polymer;
• wherein said biocompatible polymer is pre-compressed before filling, is an expansive polymer, and comprises a carbon fiber reinforcing component;
• wherein said fiber tube and said biocompatible polymer further comprises one or more active agents selected from the group consisting of a drug, antimicrobial agent, antibiotic, bone healing promoting agent, chemotherapeutic agent, or bone precursor such as osteoblast or osteoclast;
• wherein at least one physical property of said biocompatible polymer is altered by an external stimulus that is either electrical or thermal energy;
• wherein said first hole and said second hole act as shear keys after being filled with the biocompatible polymer.
