Bone marrow harvesting and storage
Methods of extracting bone and/or cellular material from a patient for possible use in a later surgical procedure, which involves that patient or even a different patient, are provided. An embodiment of the method generally comprises extracting bone and/or cellular material from a patient undergoing a routine surgical procedure, saving the material, and then sending it to a storage, separation, and processing facility (e.g., a “biobank”) for use in a later surgical procedure involving that patient, or a different patient. The material may be cancellous bone, cortical bone chips, or bone marrow. The extracted bone and/or cellular material can be processed at the biobank and used in a multitude of different medical procedures (e.g., as an allograft infused with stem cells for use in a fusion procedure).
1. A method of processing, separating, and storing extracted bone or cellular material comprising:
identifying a set of patients undergoing an existing surgical operation in which a bone of the patient is to be reamed or resected and cancellous bone, cortical bone chips, and bone marrow material removed;
screening the patients using a set of criteria to ascertain a subset of patients who qualify to donate cancellous bone, cortical bone chips, and bone marrow, wherein a first aspect of the criteria requires the patient to be undergoing an existing operation in the ordinary course of events, which is not a surgery dedicated predominantly to extracting the cancellous bone, cortical bone chips, and bone marrow material;
extracting cancellous bone, cortical bone chips, and bone marrow from the subset of patients using a reamer-irrigator-aspirator;
instructing a controlling entity for the surgical operation to send the extracted cancellous bone, cortical bone chips, and bone marrow material to a processing, separation, and storage facility; and
processing, separating, and storing the cancellous bone, cortical bone chips, and bone marrow material, by the processing, separation, and storage facility, so that the material is usable as at least one of: (1) an allograft infused with stem cells; (2) an autograft with or without stem cells infused; and (3) stem cells.
2. The method according to claim 1 , wherein the criteria used for screening also involves considering the patient's age, health, and quality of the extracted cancellous bone, cortical bone chips, and bone marrow material being donated.
3. The method according to claim 1 , further comprising the step of maintaining a stem cell biobank using at least one of the extracted cancellous bone, cortical bone chips, and bone marrow material.
4. The method according to claim 2 , further comprising the step of supplying stem cells to qualifying patients in need after the processing, separating, or storing step.
5. The method according to claim 1 , further comprising the step of instructing the controlling entity to save and not discard the extracted cancellous bone, cortical bone chips, and bone marrow material, wherein typical practice for the controlling entity is to discard such material.
6. The method according to claim 1 , further comprising the step of accepting payment from the screened patient or patients to store and/or process their extracted cancellous bone, cortical bone chips, and bone marrow material for future use.
7. The method according to claim 1 , wherein the cancellous bone, cortical bone chips, and bone marrow material, after processing and/or separation, is stored as stem cells in a biobank.
8. A method of processing, separating, and storing extracted bone or cellular material comprising:
identifying a set of patients undergoing an existing surgical operation in which cancellous bone, cortical bone chips, and bone marrow material is to be removed from the patient;
screening the patients using a set of criteria to ascertain a subset of patients who qualify to donate the cancellous bone, cortical bone chips, and bone marrow material, wherein a first aspect of the criteria requires the patient to be undergoing an existing operation in the ordinary course of events, which is not a surgery dedicated predominantly to extracting the cancellous bone, cortical bone chips, and bone marrow material;
extracting cancellous bone, cortical bone chips, and bone marrow from the subset of patients using a reamer-irrigator-aspirator;
obtaining and saving the extracted cancellous bone, cortical bone chips, and bone marrow material resulting from the surgical operation, wherein the cancellous bone, cortical bone chips, and bone marrow material would have otherwise been discarded after the surgical operation; and
sending the cancellous bone, cortical bone chips, and bone marrow material to a processing, separation, and storage facility for processing, separating, and storing the cancellous bone, cortical bone chips, and bone marrow material so that the material is usable as at least one of: (1) an allograft infused with stem cells; (2) an autograft with or without stem cells infused; and (3) stem cells.
9. The method according to claim 8 , wherein the cancellous bone, cortical bone chips, and bone marrow material, after processing and/or separation, is stored as stem cells in a biobank.
10. The method according to claim 9 , further comprising establishing a registry categorizing the stem cells for future use by the patient or another patient.
11. The method according to claim 10 , further comprising identifying a second patient as a candidate for benefiting from use of the patient's stem cells using the registry, and supplying the second patient with such cells for use in a surgical operation.
12. The method according to claim 8 , wherein the criteria used for screening also involves considering the patient's age, health, and/or quality of the extracted cancellous bone, cortical bone chips, and bone marrow material being donated.
13. The method according to claim 8 , wherein the surgical operation is an orthopedic operation involving reaming of a bone of the patient, in particular a medullary canal of the bone.
