Jigs, systems, and methods for correcting joint deformities
A system includes a first tool. The first tool includes a first component, a second component, and at least one fastener for coupling the first component to the second component. The first component is coupled to the second component such that a distance between the first component and the second component in a first direction is adjustable. The first tool is configured to provide a controlled adjustment of a first bone relative to a second bone in a second direction that is different from the first direction.
1 . A system, comprising:
a first tool, including:
a first component;
a second component; and
at least one fastener for coupling the first component to the second component, the at least one fastener including a first threaded fastener for coupling the first component to the second component and for adjusting the distance between the first component and the second component;
a second tool for positioning the first tool relative to a joint, the second tool configured to be coupled to an unthreaded section of the first threaded fastener;
a third tool including a frame having a coupling section for coupling the third tool to the first tool; and
a tool holder subassembly coupled to the frame, the tool holder subassembly including a tool guide for guiding a surgical instrument, the tool holder subassembly further includes a body for being coupled to the frame such that the body may be rotated relative to the frame, the body further configured to support the tool guide such that the tool guide is able to pivot about a pivot point;
wherein the first component is coupled to the second component such that a distance between the first component and the second component in a first direction is adjustable, and
wherein the first tool is configured to provide a controlled adjustment of a first bone relative to a second bone in a second direction that is different from the first direction.
2 . The system of claim 1 , wherein the first threaded fastener includes:
a first threaded section having at least one thread of a first type; and
a second threaded section having at least one thread of a second type that is different from the first type.
3 . The system of claim 2 , wherein the first threaded fastener includes an unthreaded section disposed between the first threaded section and the second threaded section, the unthreaded section including an area having an enlarged diameter relative to at least one of the first threaded section and the second threaded section.
4 . The system of claim 1 , wherein the at least one fastener includes a first unthreaded fastener for preventing rotation of the first component relative to the second component.
5 . The system of claim 1 , wherein
the first component is configured to receive a first insert, the first insert configured to rotate relative to the first component; and
the second component is configured to receive a second insert, the second insert configured to rotate relative to the second component.
6 . The system of claim 5 , wherein the first component is configured to move axially relative to the second component in response to a second fastener being rotated relative to the first component.
7 . The system of claim 5 , wherein each of the first component and the second component is configured to receive a respective fixation device for securing the first tool to at least one bone.
8 . The system of claim 1 , wherein
the second component defines a slot and a first hole,
the slot is sized and configured to receive a fixation device for coupling the second component to a bone,
the first hole is in communication with the slot and is sized and configured to receive a second fastener such that movement of the second fastener along an axis defined by the first hole causes movement of the fixation device when the fixation device is received within the slot.
9 . The system of claim 1 , wherein the body defines a hole for receiving a locking device for preventing rotation of the body relative to the frame.
10 . The system of claim 1 , wherein the body includes a track defining a curved channel for supporting the tool holder as the tool holder pivots about the pivot point.
11 . The system of claim 1 , wherein the the tool guide defines a hole for receiving a locking device for preventing rotation of the the tool guide relative to the frame.
12 . The system of claim 1 , wherein the the tool guide includes a track defining a curved channel for supporting the tool holder as the tool holder pivots about the pivot point.
13 . A system, comprising:
a first tool for being coupled to a first bone and a second bone that together form a joint, the first tool including:
a first body component configured to receive one or more fixation devices for coupling the first body component to the first bone,
a second body component configured to receive one or more fixation devices for coupling the second body component to the second bone,
a first threaded fastener for coupling the first body component to the second body component and for adjusting the distance between the first component and the second component, the first threaded fastener including a first threaded section and a second threaded section;
a second tool for positioning the first tool relative to the joint, the second tool configured to be coupled to an unthreaded section of the first threaded fastener;
a third tool including a frame including a coupling section for coupling the third tool to the first tool; and
a tool holder subassembly coupled to the frame, the tool holder subassembly including a tool guide for guiding a surgical instrument, the tool holder subassembly further includes a body for being coupled to the frame such that the body may be rotated relative to the frame, the body further configured to support the tool guide such that the tool guide is able to pivot about a pivot point;
wherein rotation of the first threaded fastener in a first direction causes the first and second body components to move toward each other in a second direction to compress the joint and rotation of the first threaded fastener in a third direction causes the first and second body components to move away from each other in a fourth direction to distract the joint, and
wherein the first body component is configured to translate in a fifth direction relative to the second body component to translate the first bone relative to the second bone.
