US 10,889,029 B2 · Methods of augmenting, reducing, and repairing bone with thermoplastic materials

Abstract

A method for augmenting a tissue including introducing into the tissue a first thermoplastic material at a first condition; treating the first thermoplastic material to achieve a second condition that includes an at least partially crystalline skin; and introducing a second material into the tissue whereby the first thermoplastic material and the second material are contained by the at least partially crystalline skin. Also a method of fracture reduction in a tissue including exposing to gamma radiation a mass of polycaprolactone characterized by a first shape; heating the mass of irradiated polycaprolactone above its melting temperature; introducing the heated mass of polycaprolactone into the tissue annulus to deform it from the first shape; allowing the material to return to the first shape.

Dependent claims

A method for preparing a modified polycaprolactone composition for hardware fixation as part of fracture treatment, comprising:

blending a polycaprolactone composition with a radiopacifier to create a modified composition;
shaping the modified composition into a first shape;
and
inducing a shape memory property to the modified composition;
after the inducing step, heating the modified composition above a melting temperature thereof so that the modified composition achieves a second shape deformed from the first shape;
cooling the modified composition below the melting temperature, the modified composition having a recrystallization rate higher than the polycaprolactone composition;
and
cooling the modified composition below the melting temperature so that the modified composition transitions from the second shape to a shape that approximates the first shape.
