摘要:
Disclosed is a fixation device for spinal fixation. The fixation device includes an elongated body comprising a bone anchor at a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. In one embodiment, the device is inserted through a first vertebra and the bone anchor is rotated into positioned within a second vertebra. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the first and second vertebra. In other embodiments, the device is used to secure stabilization devices across two or more vertebra.

Apparatuses for attaching tissue to bone are provided. In one exemplary embodiment, the apparatus includes an expandable body defining a bore, an expander pin having a shaft sized to be received in the bore of the expandable body, and an insertion shaft slidingly disposed in the bore of the expandable body and in a bore of the expander pin. The body is configured to expand laterally into and attach to bone when the expander pin is driven into the expandable body. The body includes a proximal main member having a distally extending threaded projection and a harder, distal tip member having a threaded recess in a proximal surface thereof such that the projection is threadedly interengageable with the recess. The expansion of the body by way of the pin can occur when the proximal main member and distal tip member are threadedly engaged. The insertion shaft is releasably secured to the expandable body and extends distally beyond the expandable body.

A suture anchor for anchoring a suture to bone, the suture anchor comprising: an elongated body having a distal end surface, a proximal end surface, an exterior sidewall extending between the distal end surface and the proximal end surface, and an interior passageway extending between the distal end surface and the proximal end surface; and an actuator comprising a distal end, a proximal end and a shaft extending between the distal end and the proximal end, the distal end of the actuator comprising a suture retainer mechanism movably disposed relative to the elongated body.

A suture anchor is disclosed having an outer body with an axial bore which receives and inner body for rotation. Suture passes between the inner body and outer body and rotation of the inner body wraps the suture thereabout locking the suture thereto. Rotation of the inner body also effects radial expansion of at least a portion of the outer body to engage to anchor into a bone hole.

摘要:
A method for threading a suture in a patient's body. The method includes the steps of providing a suture, providing a threading device comprising an elongated rod having a suture tie-off location and first and second ends, tying the suture to the suture tie-off location, inserting the first end of the elongated rod through a first opening in the patient's skin, passing the first end of the elongated rod subcutaneously to a second opening in the patient's skin, pulling the first end of the elongated rod and a portion of the suture through the second opening, without turning the elongated rod around, and passing the second end of the elongated rod subcutaneously to an opening in the patient's skin. At least one point during the performance of the method the first end of the elongated rod extends out of the first opening and the second end of the elongated rod extends through the second opening. In a preferred embodiment, the first and second ends of the threading device are each lighted at predetermined points during the method.

Provided herein is a method of marking the skin before surgery. The method includes the steps of providing first and second tape members each having a plurality of perforations defined therethrough, placing the first tape member on a portion of the skin overlying the right submandibular border, placing the second tape member on a portion of the skin overlying the left submandibular border, marking the skin through at least one of the perforations in the first tape member, marking the skin through at least one of the perforations in the second tape member, and removing the first and second tape members from the skin. In a preferred embodiment, the markings made using the first tape member are symmetrical with the markings made with the second tape member.
摘要:
An improved method for attaching soft tissue to bone by passing a suture through an opening in the bone, e.g., a transosseous tunnel, and affixing the soft tissue with the suture. The improvement, for preventing the suture from migrating through the bone at the end of the opening, includes placing a eyelet into an end of the bone opening and passing the suture through the eyelet, as well as through the opening in the bone, in order to affix the soft tissue to the bone with the suture.
