Patient-specific glenoid depth control
A system for reaming a bone including a guiding wire configured to be attached to the bone; a tubular depth guide configured to cover at least a portion of the guiding wire, the tubular depth guide including a first end configured to abut the bone, and a second end opposite the first end; a reaming device including an elongate recess therein that extends between a reaming tool of the reaming device and an interior of a handle of the reaming device, wherein the elongate recess is configured to receive each of the guiding wire and depth guide therein, the elongate recess includes a reduced diameter section that defines a shoulder, and the shoulder is designed to abut the second end of the tubular depth guide to control a depth to which the bone is reamed.
1. A system for reaming a bone, comprising:
a patient-specific guiding wire configured to be attached to the bone;
a tubular depth guide configured to cover at least a portion of the patient-specific guiding wire, the tubular depth guide including a first end configured to abut the bone, and a second end opposite the first end;
a reaming device including an elongate recess therein that extends between a reaming tool of the reaming device and an interior of a handle of the reaming device,
wherein the elongate recess is configured to receive each of the guiding wire and depth guide therein,
the elongate recess includes a reduced diameter section that defines a shoulder, and
the shoulder is designed to abut the second end of the tubular depth guide to control a depth to which the bone is reamed.
2. The system of claim 1 , wherein a length of the tubular depth guide is patient-specific or corresponds to a specific reaming depth.
3. The system of claim 1 , wherein the tubular depth guide is formed from titanium, CoCr, or steel.
4. The system of claim 1 , wherein the tubular depth guide is formed from at least one of polyethylene, polypropylene, polystyrene, nylon, and polyether ether ketone (PEEK).
5. The system of claim 1 , further comprising a guide member for aligning the guiding wire relative to the bone.
6. The system of claim 5 , wherein the guide member includes a patient-specific bone engagement surface.
7. The system of claim 6 , wherein the bone engagement surface is complementary to a surface of the bone to be reamed.
8. The system of claim 5 , wherein the guide member includes first guide and a second guide that are configured to align the guiding wire relative to the bone in a first orientation and a second orientation.
9. A method for reaming a bone, comprising:
attaching a guiding wire to the bone;
covering at least a portion of the guiding wire with a tubular depth guide, the tubular depth guide including a first end configured to abut the bone, and a second end opposite the first end;
reaming the bone with a reaming device, the reaming device including an elongate recess therein that extends between a reaming tool of the reaming device and an interior of a handle of the reaming device,
wherein the elongate recess is configured to receive each of the guiding wire and depth guide therein,
the elongate recess includes a reduced diameter section that defines a shoulder, and
the shoulder is designed to abut the second end of the tubular depth guide to control a depth to which the bone is reamed.
10. The method of claim 9 , wherein a length of the tubular depth guide is patient-specific or corresponds to a specific reaming depth.
11. The method of claim 9 , wherein the tubular depth guide is formed from titanium, CoCr, or steel.
12. The method of claim 9 , wherein the tubular depth guide is formed from at least one of polyethylene, polypropylene, polystyrene, nylon, and polyether ether ketone (PEEK).
13. The method of claim 9 , further comprising placing a guide member relative to the bone before attaching the guiding wire to the bone, the guide member configured to align the guiding wire relative to the bone.
14. The method of claim 13 , wherein the guide member includes a patient-specific bone engagement surface.
15. The method of claim 14 , wherein the bone engagement surface is complementary to a surface of the bone to be reamed.
16. The method of claim 13 , wherein the guide member includes first guide and a second guide that are configured to align the guiding wire relative to the bone in a first orientation and a second orientation.
17. A method for reaming a glenoid for an arthroplasty, comprising:
positioning a patient-specific glenoid guide proximate the glenoid, the glenoid guide including a first primary drill guide extending along a first axis and a second primary drill guide extending along a second axis;
selecting one of the first and second axes for orienting a guiding wire, and positioning a guiding wire in the glenoid that extends along the selected axis;
positioning a tubular depth guide over the guiding wire such that a first end of the depth guide abuts the bone and the guiding wire extends outward from a second of the depth guide;
positioning a reaming device over the guiding wire, and reaming the glenoid along the selected axis,
wherein the reaming device includes an elongate recess therein that extends between a reaming tool of the reaming device and an interior of a handle of the reaming device,
the elongate recess is configured to receive each of the guiding wire and depth guide therein,
the elongate recess includes a reduced diameter section that defines a shoulder, and
the shoulder is designed to abut the second end of the tubular depth guide to control a depth to which the bone is reamed.
18. The method of claim 17 , wherein a length of the tubular depth guide is patient-specific or corresponds to the depth to which the bone is reamed.
19. The method of claim 13 , wherein the glenoid guide includes a patient-specific bone engagement surface.
20. The method of claim 19 , wherein the bone engagement surface is complementary to the glenoid.
