Abstract
Devices and instruments for use in spinal alignment or spinal reduction include a connector rod designed to attach to a spinal rod connector, a push rod designed to push against a spinal rod, and a connector member designed to hold the rods in adjustable angular relation. Methods of use are also disclosed.
Claims28
A device for spinal reduction comprising:
- a first elongated member, comprising an attachment end configured to attach to a spinal rod connector during use;
- a second elongated member, wherein one end thereof is configured to contact a spinal rod during use;
- a connecting member configured to engage the second elongated member, wherein the engagement point is adjustable along at least a part of the length of the second elongated member;
- and
- a locking mechanism configured to secure the connecting member to the first elongated member;
- wherein the connecting member is configured to provide an adjustable angle between the first elongated member and the second elongated member during use.
3 more elements
A spinal reduction instrument, comprising:
- an elongated push rod;
- a connector rod comprising a member configured to connect to a fixation device;
- and
- a plate;
- wherein the plate is configured to provide a connection between the push rod and the connector rod so that the push rod and the connector rod are held in adjustable angular relation, and further wherein the push rod is moveable along at least a portion of its length with respect to the plate.
2 more elements
A device for spinal reduction comprising:
- a first elongated member, comprising an attachment end configured to attach to a spinal rod connector during use, wherein the first elongated member comprises a threaded inner shaft disposed in an outer shaft with mating internal threads, and wherein turning the inner shaft with respect to the outer shaft is effective to reversibly move the attachment end from a locked configuration to an unlocked configuration;
- a second elongated member, wherein at least a part of the second elongated member comprises threading, and wherein one end thereof is configured to contact a spinal rod during use;
- a connecting member comprising a threaded opening configured such that the second elongated member is threadable through the threaded opening;
- and
- a locking mechanism configured to secure the connecting member to the first elongated member;
- wherein the connecting member is configured to provide an adjustable angle between the first elongated member and the second elongated member during use.
3 more elements
A method of manufacturing a spinal reduction device comprising:
- providing a first elongated member comprising an attachment end configured to attach to a spinal rod connector during use;
- providing a second elongated member, wherein one end thereof is configured to contact a spinal rod during use;
- providing a connecting member configured to engage the second elongated member, wherein the engagement point is adjustable along at least a part of the length of the second elongated member, and wherein the connecting member is configured to provide an adjustable angle between the first elongated member and the second elongated member during use;
- and
- providing a locking mechanism configured to secure the connecting member to the first elongated member during use.
2 more elements
A spinal reduction instrument, comprising:
- an elongated push rod;
- a connector rod;
- and
- a plate;
- an eyebolt configured to hold the connector rod in the eye of the eyebolt and to provide a threaded projection through the plate, so that turning a threaded member on the threaded projection is effective to press the connector rod against the plate;
- wherein the plate is configured to provide a connection between the push rod and the connector rod so that the push rod and the connector rod are held in adjustable angular relation, and further wherein the push rod is moveable along at least a portion of its length with respect to the plate.
