摘要： Instruments and methods for determining the spacing between locations in an animal subject are employed to size a connecting element to secure along a bony segment in the animal subject. The instruments and methods include a measuring instrument mountable to proximal ends of extensions extending from anchors engaged to the bony segment. The measuring instrument is configured to provide an indication of the spacing between the anchors even if the extensions are in non-parallel relation to one another.

摘要： A spinal implant is provided that includes a first component for engaging a first vertebra, a second component for engaging a second vertebrae, and a damping member is positioned therebetween. The damping member has at least two chambers connected by an opening. A fluid is disposed within the chambers such that compression of the first and second components towards one another causes the fluid to be displaced from one of the chambers to another chamber through an opening. The opening has a reduced size relative to the chambers to restrict the flow of the fluid between the chambers and provide a dampening effect. In some instances, the rheologic properties of the fluid positioned within the chambers are dependent upon the strength a magnetic field passing through the fluid. In other aspects of the present disclosure, prosthetic devices, intervertebral implants, spinal systems, implantation methods, and treatment methods are provided.

摘要： A pivoting connector couples a vertebral member to a longitudinal member. An anchor is pivotally attached to a body by positioning a head of the anchor within a cavity in the body. A longitudinal rod is inserted into a channel also positioned within the body and axially aligned with the cavity. A retainer applies a force to maintain the longitudinal rod within the channel, however the force may be isolated from the anchor. The cavity is adjustable between a plurality of sizes that apply different resistances to pivoting movement of the anchor relative to the body. The adjustment may be performed before or during a surgical procedure. The adjustment may be performed by inserting different components or by rotating a threaded element to create more or less rotational interference.

摘要： Systems for positioning a connecting element adjacent the spinal column in minimally invasive surgical procedures include one or more extenders removably engaged to one or more anchors engaged to a bony segment. The anchor extenders provide a reference to the respective anchor locations within the patient even when the anchor is obstructed by skin and/or tissue of the patient. An inserter can be movably mounted to the one or more anchor extenders, or an inserter can be employed without mounting to the one or more anchor extenders. In either form, the inserter is operable to position a stabilization element relative to the anchors for engagement to the anchors to stabilize the bony segment to which the anchors are engaged. At least one of the one or more anchor extenders includes a reduction assembly that is operable to move one or more portions of the bony segment while maintaining the minimally invasive character of the procedure.

摘要： A surgical apparatus for guiding the position of a medical device to a desired location includes an outer sleeve, a tether, and at least one elastic anchor hook engaged with the tether. The tether may be slideably moveable within the outer sleeve. Additionally, the anchor hook is configured to anchor into bone at the desired location. In certain embodiments, the anchor hook is elastically deformable from an unstressed curved shape to a deformed straightened shape. The anchor hook may be deformed to the straightened shape when positioned within the outer sleeve and may reform to the curved shape upon deployment from the outer sleeve. In certain embodiments, a rod surrounds part of the tether and is used for threading through medical devices to advance the medical devices to the desired location. Additionally, a deployment button may be used to deploy the anchor hooks from the outer sleeve.

摘要： A pivoting connector couples a vertebral member to a longitudinal member. An anchor is pivotally attached to a body by positioning a head of the anchor within a cavity in the body. A longitudinal rod is inserted into a channel also positioned within the body and axially aligned with the cavity. A retainer applies a force to maintain the longitudinal rod within the channel, however the force may be isolated from the anchor. One embodiment may include a compression member that is separate from or integral with the body. The compression member may transmit a rod securing force to the anchor to secure or limit the pivoting movement of the anchor member relative to the body. The compression member may deflect or detach under the influence of the securing force.
