Stabilization of vertebral bodies with bone particle slurry
First Claim
Patent Images
1. A method of structurally supporting a vertebral body comprising:
- forming one or more openings to a central portion of a vertebral body and placing a cannula through a first opening of the one or more openings;
injecting a slurry of bone particles through the cannula, wherein the slurry of bone particles consists essentially of bone particles, water, and optionally one or more additional ingredients selected from salts, growth factor, blood, platelets, contrast agent, stem cells, antibiotics, chemotherapeutic agents, bisphosphonates, and osteoporosis therapy drugs,pressurizing the slurry during and/or after the injecting to force bone particles of the slurry into direct contact with bone tissue inside the vertebral body.

Abstract
A medical implant comprises a slurry of bone particles that are injected into a vertebral body under pressure. The liquid component of the slurry may be aspirated while the slurry is being injected so that the bone particles of the slurry pack into the central area of the vertebral body to provide structural support. The injected slurry may be agitated during the procedure to maximize the structural strength of the implant after the procedure.
