Abstract:
1. A method of treating a bone fracture using a biologic intramedullary fixation device including an internal tubular wall formed of a bioabsorbable synthetic material, and an outer wall coupled with and surrounding the internal tubular wall with an annular space therebetween, the outer wall being at least partially fenestrated and being formed of the bioabsorbable synthetic material, the method comprising: (a) forming a cavity in the bone that extends across the bone fracture; (b) inserting the biologic intramedullary fixation device in the cavity; and (c) inserting a set screw in an end of the internal tubular wall without covering the annular space; and (d) injecting a biologically replaceable cement material into the annular space between the internal tubular wall and the outer wall without injecting the biologically replaceable cement material within the internal tubular wall, wherein the biologically replaceable cement material penetrates the area adjacent the bone fracture through the fenestrations in the outer wall.
