The present invention relates to a system, method, device and kit which utilize a modular pedicle screw implant that does not require the use of a guide wire for implantation and can be assembled in situ. The system, method, device, and kit include a surgical instrument for implanting a modular pedicle screw comprising a cannula coaxially aligned with a modified trocar style instrument or surgical shaft. The surgical shaft contains a first member of a surgical shaft-inner pedicle bone screw member joint, illustrated herein as a locking taper, for securing an inner member of a pedicle screw thereto. The inner member of a pedicle screw is further adapted to couple to an outer pedicle sheath. In combination, the inner member of a pedicle screw and the outer pedicle sheath form a solid modular pedicle screw.

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

A method comprises the steps of: imaging a patient anatomy; selecting an implant strategy for at least one bone fastener having a first member; registering the imaging of the patient anatomy with imaging of at least a portion of a robot; engaging the first member with tissue of the patient anatomy via robotic guidance according to the implant strategy; and subsequently, manipulating the patient anatomy. Systems, spinal constructs, implants and surgical instruments are disclosed.

Self-drilling, self-tapping and self-advancing orthopedic screws are provided. An orthopedic screw includes a relief cut at the tip of the screw that is timed to the distal-most thread at the end of the screw tip to create a wide and sharp cutting edge for the screw.

A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. One or more resilient teeth project inward of the peripheral portion into the central opening and are configured to exert a biasing force in an axial direction when deformed in a direction opposite the axial direction.

This disclosure is directed to surgical fixation devices (e.g., staples, screws, etc.) which are able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The surgical fixations devices are manufactured from a shape memory material (e.g., a material capable of exhibiting superelasticity and/or a temperature-induced shape change).

A modular medical implant allowing the targeted injection of a liquid or pasty material into a bone cavity. This implant is produced with four types of modules provided with a lumen and of variable lengths, including: either a male securing principle, referred to as proximal modules, or a female securing principle, referred to as distal modules, or a male securing principle and a female securing principle, referred to as intermediate modules and perforated intermediate modules, that can be secured in a predetermined order and number in order to position the perforated intermediate modules at suitable levels to allow an injection product to be conveyed to and diffused at the targeted locations, via the perforations, while producing the required length of the implant. The implant is intended, in general, for surgical operations and, in particular, for interventional radiology.

A stylet control system for selectively advancing and retracting a stylet includes a stylet having a first end and a second end, the second end being threaded, a screwdriver defining a bore for receiving a portion of the stylet and having a screw-engaging end for engaging a screw, the stylet being rotationally fixed relative to the screwdriver. The system includes a control device having a passage for receiving the screwdriver and having an inner portion defining a lumen for receiving the portion of the stylet, the inner portion being threaded for engaging the threaded second end of the stylet, when the screwdriver is rotated in the first rotation direction and the control device is prevented from rotating, the screwdriver advances the screw in the first axial direction and the stylet retracts in a second axial direction, opposite the first axial direction.

A bone screw includes a screw body having a head at one end of the screw and a tip at an opposite end of the screw; head threads directly attached to the screw body and continuous around the head of the screw; tip threads directly attached to the screw body and continuous around the tip of the screw; and overhanging thread portions between the head threads and the tip threads, the overhanging thread portions spaced apart, with unthreaded channels between the overhanging thread portions and the overhanging thread portions overhanging a portion of the unthreaded channels.

A bone anchor for the fixation of bone components and bone fragments, including a shaft, a neck area and a head located in proximal direction and a tip located in distal direction, wherein the bone anchor has a mainly cylindrically shaped hollow chamber extending along the central axis, wherein the hollow chamber is adjacent a transition zone located proximally from a central plane, characterized in that the transition zone at least partially has an inner diameter and the hollow chamber at least partially has an opening diameter, and the opening diameter of the hollow chamber is greater than the inner diameter of the proximal transition zone.
