A bone insert is provided that includes a cap having a convex top surface made from a plurality of cap micro struts, an elongated stem made from a plurality of stem micro struts, and a barrier between the cap and the stem. The stem of the bone insert is inserted into a hole formed in a host bone until the barrier is pressed against the exposed bone. The bone implant can be placed against a small focus contact point on the cap. Liquid cement can be injected into a large center hole in the cap and the cement can flow through the fenestrations between all of the cap micro struts as well as the space between the bone implant and the bone. The cement can cure to create a high strength structure that provides a strong bond between the bone implant and the host bone.

Various torque-limiting screwdriver devices, systems, and methods are disclosed. The screwdriver can include a body, a motor that is configured to rotate a screw engaged with the screwdriver, and a processor configured to control operation of the screwdriver. The screwdriver can have torque-limiting functionality, such as by monitoring the amount of torque applied to the screw and reducing or stopping rotation of the screw when certain torque-limiting criteria are met. In some embodiments, the screwdriver can be switched between manual operation by a user, and automated operation by a motor within the screwdriver. In some embodiments, the screwdriver can be attached to a robotic arm.

Systems, methods, and program products for providing and administering a digital asset network of cooperative nodes with rapid transaction settlements are disclosed.

A driven fastener guide for guiding a fastener into a hole of a bone plate. The driven fastener guide includes an elongated driver configured for connecting to a drill and a fastener guide member operably connected to the elongated driver. The fastener guide member includes a split body and a through-bore configured for receiving the fastener. The fastener guide member is configured for aligning the fastener relative to the hole of the bone plate.

A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.

A wireless pedicle screw system and method of use for fixation and/or stabilization of vertebral bodies using pedicle screws and rods or plates is described. The wireless pedicle screw system includes a dilator tube having a generally elongated body defined by a continuous wall. The elongated body has a proximal end, a distal end, and an inner lumen running the length of the elongated body sized to receive and enclose various pedicle screw implant instruments. Positioned at the distal end are alignment/positioning members constructed to properly aid a surgeon in aligning the dilator tube to portions of the vertebra. Proper placement about the vertebra using the engagement members results in the ability to insert pedicle screws, resulting in minimizing tissue trauma, reducing operating room time, reducing X-Ray radiation exposure, and eliminating the need for k-wire guidance.

A device for use in spinal surgery or musculoskeletal surgery, or in simulated surgery, where the device is non-implantable, includes a first component having a first end, a second end, and a longitudinal axis extending between the first and second ends, wherein the first end is connectable to a second component in an adjustable manner, and a detection device configured to monitor position changes of the second component relative to the first component and to deliver position data corresponding to the position changes to an evaluation unit that is separate from the device. At least part of the detection device at or near the first end of the first component is movable laterally away from the longitudinal axis to monitor movement of at least part of the second component away from the longitudinal axis.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.

Disclosed are methods for correcting hallux varus joint deformity in a foot. The method can include forming a first hole in a first metatarsal of the foot from a medial side to a lateral side of the first metatarsal. A second hole can be formed in a proximal phalanx of a hallux that extends from a medial side to a lateral side of the proximal phalanx. The method includes passing a suture through the first hole, along a lateral side of a first metatarsal phalangeal joint, and through the second hole. The suture can be tensioned between the first and second holes to reduce the hallux to a rectus position relative to the first metatarsal. The suture can be secured within the first and second holes with a first interference screw inserted within the first hole and a second interference screw inserted within the second hole.
