Harvesting cancellous bone and marrow from posterior superior iliac spine using bone press

A method of harvesting cancellous bone and marrow from an individual's posterior superior iliac spine using a bone press apparatus, comprising the steps of:

• (a) creating an opening in cortical bone of the posterior superior iliac spine;
• (b) accessing through the opening and loosening for extraction cancellous bone and bone marrow;
• (c) inserting a suction apparatus through the opening and extracting the loosened cancellous bone and bone marrow, the bone marrow comprising a liquid, the suction apparatus being attached to a first lid of a collection container, the first lid of the collection container covering a first cup of the collection container and having a suction port to which a suction source is connected;
• (d) after extracting the cancellous bone and bone marrow, disconnecting the suction source from the suction port of the first lid;
• (e) removing the first lid of the collection container from the first cup of the collection container;
• (f) attaching a second lid to the first cup of the collection container, the second lid having a suction port and a plunger with a press head configured to filter the extracted liquid contained in the first cup;
• (g) filtering the extracted liquid by depressing the plunger of the second lid toward a bottom of the first cup;
• and
• (h) pouring the filtered liquid from the first cup through the suction port of the second lid into a second cup while depressing the plunger, thereby separating the liquid from a spongy semi-solid mass of cancellous bone that remains in the first cup.
