  • Publication number: 20240358413
    Abstract: A revision connector that is configured to couple a new spine fixation rod to a previously implanted spine fixation rod that is secured to a plurality of vertebrae. The previously implanted spine fixation rod may be received in a first rod receiving channel of the revision connector. The revision connector may include a linkage that is received in a second rod receiving channel of another revision connector. For example, the another revision connector may couple to the new spine fixation rod such that the revision connector is coupled to the new fixation rod. A bone anchor may not directly connect either of the revision connector or the another revision connector to underlying vertebra. Also, the new spine fixation rod can be implanted and secured to vertebra that are caudal and/or cranial with respect to the previously secured vertebrae.

  • Publication number: 20240285319
    Abstract: A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.

  • Publication number: 20240285314
    Abstract: The present disclosure includes a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

  • Patent number: 12016603
    Abstract: A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.

  • Patent number: 11185355
    Abstract: A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.
