1. A formed in place orthopedic device, comprising:
- an outer wall, defining a cavity therein; and
a hardenable media within the cavity to form the orthopedic device, said hardenable media comprising a resin and hardener mixture that is substantially cured at a temperature below about 45°
C. in about 90 minutes or less;
wherein the hardenable media is hardened while the device is positioned within the body of a patient to create the formed in place orthopedic device.

Abstract
A subcutaneously formed in place orthopedic fixation device is provided, such as for fixation of the spine or other bone or bones. The device comprises an inflatable member, such as a tubular balloon. The balloon is positioned at a treatment site in the body while in a flexible, low crossing profile configuration. The balloon is thereafter inflated with a hardenable epoxy media comprising one or more epoxy compounds and one or more amine curing compounds that cures rapidly in place with low to moderate exotherm. Methods and delivery structures are also disclosed.
