Abstract

Single use or disposable cutting blocks and methods for utilizing same are disclosed. The blocks are preferably constructed of polymer and/or other suitable low cost and light weight materials. The blocks may be adapted for use with low friction cutting instruments, as well as other such cutting instruments. Several differently sized and configured blocks may be utilized to perform a single surgical procedure.
In addition, kits housing one or more such blocks, with or without other instruments are possible.

Claims (22)

1. A method of performing a surgical procedure on a patient comprising:
providing at least one cutting block constructed of polymeric material, the cutting block having at least one guiding surface;
providing a low friction cutting instrument suitable for cutting a bone of the patient, the cutting instrument having an oscillating portion and a non-oscillating portion;
positioning the cutting block with respect to the bone of the patient; and cutting a portion of the bone of the patient by guiding the low friction cutting instrument along the guiding surface of the cutting block, wherein the oscillating portion of the cutting instrument that cuts the bone of the patient is spaced from the guiding surface of the cutting block and the non-oscillating portion of the cutting instrument is guided by the guiding surface of the cutting block.
2. The method of performing a surgical procedure according to claim 1, wherein the surgical procedure is a total knee arthroplasty.
3. The method of performing a surgical procedure according to claim 2, wherein three cutting blocks are provided.
4. The method of performing a surgical procedure according to claim 3, wherein a first cutting block is adapted to make a single resection across the distal end of a femur of the patient, a second cutting block is adapted to make anterior and posterior resections of the femur of the patient and a third cutting block is adapted to make anterior and posterior chamfer resections of the femur of the patient.
5. The method of performing a surgical procedure according to claim 4, wherein the first cutting block is J-shaped.
6. The method of performing a surgical procedure according to claim 1, further comprising the step of affixing the cutting block to the bone of the patient.
7. The method of performing a surgical procedure according to claim 1, wherein the cutting block includes non-polymer elements.
8. The method of performing a surgical procedure according to claim 1, wherein the cutting instrument is a surgical saw including a blade assembly having an oscillating blade head.
9. The method of performing a surgical procedure according to claim 8, wherein the surgical saw further includes a motor, a battery and a trigger.
10. The method of performing a surgical procedure according to claim 1, wherein the positioning step includes the use of a navigation tracker.
11. The method of performing a surgical procedure according to claim 1, wherein the at least one cutting block is constructed of polymer selected from the group consisting of PEEK, Ultem®, polycarbonate, polystyrene, ABS, acrylics, polyetherimide, polyimide, polyethersulfone, polyphenylsulfone, polymethylmethacrylate and any fiber filled variation of these polymers.
12. A kit for use in performing a surgical procedure, the kit comprising:
at least one cutting block constructed of a polymeric material; and at least one cutting instrument suitable for use with the cutting block, wherein the cutting instrument includes an oscillating portion and a non-oscillating portion.
13. The kit according to claim 12, further comprising a plurality of bone connecting means selected from the group consisting of pins, screws and nails.
14. The kit according to claim 12, wherein the surgical procedure is a total knee arthroplasty.
15. The kit according to claim 14, wherein the kit includes three cutting blocks.
16. The kit according to claim 15, wherein a first cutting block is adapted to make a single resection across the distal end of a femur of the patient, a second cutting block is adapted to make a anterior and posterior resections of the femur of the patient and a third cutting block is adapted to make anterior and posterior chamfer resections of the femur of the patient.
17. The kit according to claim 16, wherein the first cutting block is J-shaped.
18. The kit according to claim 12, wherein the cutting instrument is a blade assembly for use with a surgical saw, the blade assembly having an oscillating blade head.
19. The kit according to claim 18, wherein the blade assembly is adapted for use with a handpiece having a motor, a battery and a trigger.
20. The kit according to claim 12, wherein the kit is sterilizably packaged.
21. The kit according to claim 12, further comprising a navigation tracker.
22. The kit according to claim 12, wherein the at least one cutting block is constructed of polymer selected from the group consisting of PEEK, Ultem®, polycarbonate, polystyrene, ABS, acrylics, polyetherimide, polyimide, polyethersulfone, polyphenylsulfone, polymethylmethacrylate and any fiber filled variation of these polymers.
