The invention relates to a bone anchor for triangular iliosacral osteosynthesis. The bone anchor includes an ilium screw having a first longitudinal direction and an iliosacral screw having a second longitudinal direction. The ilium screw, in a thread-free portion, has a preferably elongated-hole-like through-opening transversely to the first longitudinal direction, and the iliosacral screw has such a smaller outer diameter in relation to the ilium screw that the iliosacral screw can be guided through the through-opening and can be screwed proceeding from the ilium into the sacrum, through the ilium screw.

A fixation device. At least one example embodiment is a bone anchor comprising: a proximal head; a bollard coupled to the proximal head; a first barb coupled to the bollard, the first barb extends outward a first distance measured perpendicularly from an anchor central axis, the first distance greater than half the transverse dimension of the bollard, and the first barb extends outward at a first radial from the anchor central axis; and a second barb coupled to the first barb, the second barb extends outward a second distance measured perpendicularly from the anchor central axis, the second distance greater than half the transverse dimension of the bollard, and the second barb extends outward at a second radial from the anchor central axis, the second radial at a second rotational orientation at least 36 angular degrees from the first radial.

A surgical device has a shaft including a proximal portion and a distal portion being disposable with a surgical robot guide to engage vertebral tissue. The proximal portion defines a detectable marker and is connectable with at least one surgical instrument for manipulating the vertebral tissue. Systems, surgical instruments, spinal implants, constructs and methods are disclosed.

A spinal implant includes a first member configured to penetrate tissue and a second member. The second member has an abutment engageable with a surgical instrument and at least one peripheral capture element engageable with a moveable arm of the surgical instrument. Systems, spinal constructs, surgical instruments and methods are disclosed.

Surgical instrumentation and methods for reaming a bone are disclosed. In some cases, the bone is a glenoid of a shoulder. The surgical instrumentation can include a bushing that acts as a guide for a reamer, which reams the bone.

An implant driver for engaging an orthopedic implant for selective advancement and retraction of the implant. The implant driver includes a first jaw assembly comprising a helical cam surface corresponding with a first direction of rotation. The first jaw assembly is operative to engage, in response to rotation in the first direction, the implant using spherical jaw members disposed in constrictive helical channels. The implant driver includes a second jaw assembly comprising a helical cam surface corresponding with a second direction of rotation. The second jaw assembly is operative to engage, in response to rotation in the second direction, the implant using spherical jaw members disposed in constrictive helical channels. Absent rotation of the first and second jaw assemblies, the spherical jaws may not restrict relative axial movement between the implant and the implant driver to allow for advancement and/or retraction of the instrument relative to the implant.

The invention relates to an improved-structure instrument (1) for allowing the alignment of fixing screws (2) to be inserted in transverse holes (3, 13) of nails (4) for long bones, in particular medullary nails, of the type comprising an arched arm (15) having a free distal end (6) connectable to a proximal end (16) of a head (7) of the nail (4) in which the transverse holes (3, 13) are formed, and a proximal handle portion (5), as well as a connection portion (20) between the distal end (6) and the proximal handle portion (5). Advantageously, the connection portion (2) comprises at least one through-hole (23, 33) for receiving a guide tube (10) for a drilling bit, the through-hole (22, 33) having an axis coinciding with the axis of one of the transverse holes (3, 13) and manually operated quick-locking means (25) are associated with the through-hole (23, 33) so as to lock in a stable position the corresponding tube (10) inserted in the instrument (1).

A bone fixation system with variable z-axis translation is provided. The bone fixation system includes an outer tulip coupled to a bone fastener. An inner tulip, which provides a seat for an elongate fixation rod, is located inside the outer tulip. The inner tulip together with a seated rod is permitted to translate along the z-axis in an unlocked position. Also in the unlocked position, the bone fastener is free to angulate relative to the outer tulip. The bone fixation system includes a locked position in which the z-axis position of the inner tulip and rod relative to the outer tulip is fixed. Also in the locked position, the bone fastener is locked with respect to the outer tulip. The system may be adjusted between the locked and unlocked positions by way of a set screw or independently by rotation of the inner tulip relative to the outer tulip.

A method and apparatus of limiting at least one degree of movement between a superior vertebrae and an inferior vertebrae of a patient includes advancing a distal end of a stabilization device into a pedicle of the inferior vertebrae. A proximal portion of the stabilization device is positioned such that the proximal portion limits at least one degree of movement between a superior vertebrae and an inferior vertebrae by contacting a surface of the superior vertebrae.

The present invention is a dental implant tool comprising of a handle and a head portion connected to each other via a hinge facilitating the head to pivot relative to the handle to enable the dentist to reach various positions within a patient's mouth. The head portion configured to retain an abutment, an impression coping or healing abutment during a dental procedure and can be moved to the left and the right up to 90 degrees. The head comprises a rotatable ratchet with a key-shape center hole to hold an abutment in place while affixing the abutment to an implant and provides a complete access to implant-driver tip to the screw head, regarding to any abutment-body angulation, position and screw access hole. The inner wall of the center hole has 3-degree convergences at any plan of the walls in order to grasp, lock and hold implant abutments. The dental tool provides practitioners with a better and more enhanced access to the sites of the implants without any limitations, regarding to the implant while minimizing the amount of health risk exposure through increasing the level of safety standards.
