Abstract:
1. A method of facilitating bone growth in a patient having a site of a bone fracture with bone segments, comprising: positioning a flexible tubular device comprising a bioresorbable polymer material, said positioning being at the site of the bone fracture and around an external surface of the bone fracture; affixing the flexible tubular device to the bone segments to retain the bone segments and form an affixed device at the site of the bone fracture; filling micro-structure particles into said affixed device so as to apply said micro-structure particles to said fracture, wherein each of said micro-structure particles has a longitudinal axis and include a first pore extending through an entire thickness of said micro-structure particles along the longitudinal axis, said first pore having a diameter in the range of 50 μm to 1,000 μm; aligning at least a portion of said micro-structure particles within said affixed device at the site of the bone fracture along their longitudinal axes into a plurality of rows such that: applying a filler polymer having a viscosity of less than or equal to 500,000 centipoise to said aligned micro-structure particles at the site of the bone fracture; and solidifying said polymer at the site of the bone fracture.
