Abstract

In a method of performing a hyaline cartilage allograft transplantation procedure in which a surgeon has pre-operatively determined a size of allograft to be needed for the procedure, a service provider facilitates the procedure by arranging, upon receiving an order from the surgeon or a hospital for an allograft of a specified diameter, for the delivery of a precut allograft core along with a customized set of instrumentation for performing the transplantation to the surgeon or hospital prior to the scheduled time of the operation. The service provider also arranges for the return of any non-disposable instrumentation to the service provider after the operation.

Claims

1. A method for allograft bone core transplantation, comprising the step of:

placing an order for a precut allograft core by a surgeon to a core provider, the precut allograft core having a specified diameter; and

delivering the precut allograft core having the specified diameter from the core provider to the surgeon prior to a scheduled transplantation operation.

2. The method according to claim 1, wherein the precut allograft core is inserted into a clear or translucent delivery tube prior to packaging for delivery to the surgeon.

3. The method according to claim 1, further comprising:

assembling a customized instrumentation set for the transplantation operation of the precut core having the specified diameter; and

providing the customized instrumentation set simultaneously with or temporally proximate to the delivery of the precut allograft core to the surgeon prior to the scheduled operation.

5. The method according to claim 3, wherein at least some of the equipment in the customized instrumentation set is disposable.

4. A method for allograft bone core transplantation, comprising the step of:

delivering, from a core provider to a surgeon, prior to a scheduled transplantation operation, a precut allograft core having a specified diameter; and

providing for the return of at least one instrument of the customized instrumentation set to the originating location after performance of the transplantation operation.

6. A method for allograft bone core transplantation, comprising the step of:

providing donor site identifying information to surgeons or hospitals assisting surgeons in identifying a size and curvature of an allograft core needed to perform the transplantation operation;

receiving an order from a surgeon for the allograft core having a specified diameter based on the identifying information; and

delivering the precut allograft core of the specified diameter, from a core provider to the surgeon, prior to a scheduled transplantation operation.

7. The method according to claim 6, wherein the donor site identifying information is a map of donor sites available for harvesting from a donor bone.

8. The method according to claim 6, wherein the donor site identifying information is compiled into a donor site map for locating a donor site harversting site from a donor bone.

9. A method for osteochondral bone core transplantation, comprising the step of:

placing an order for a preformed osteochondral core by a surgeon to an external source, the preformed osteochondral core having a specified diameter; and

delivering from the external source to the surgeon, prior to a scheduled transplantation operation, the preformed osteochondral core having the specified diameter.

10. The method according to claim 9, wherein the preformed osteochondral core is inserted into a clear or translucent delivery tube prior to packaging for delivery to the surgeon.

11. The method according to claim 9, further comprising:

assembling a customized instrumentation set for the transplantation operation of the preformed core having the specified diameter; and

providing the customized instrumentation set simultaneously with or temporally proximate to the delivery of the preformed osteochondral core to the surgeon prior to the scheduled operation.

12. The method according to claim 11, further comprising:

returning at least one instrument of the customized instrumentation set to the originating location after performance of the transplantation operation.

13. The method according to claim 11, wherein at least one instrument of the customized instrumentation set is disposable.

14. A method for osteochondral bone core transplantation, comprising the step of:

providing donor site identifying information to surgeons or hospitals assisting surgeons in identifying a size and curvature of a preformed osteochondral core needed to perform the transplantation operation;

receiving an order from a surgeon for the preformed core based on the identifying information; and

providing from an external source to the surgeon the preformed osteochondral core having the specified diameter, prior to a scheduled transplantation operation.
