A medical decoupling instrument for decoupling a medical insertion instrument from a pedicle screw includes a shaft and a sleeve arranged around a portion of the shaft. The sleeve is configured for defined coupling to the medical insertion instrument. The shaft is rotatable relative to the sleeve, and the medical decoupling instrument is configured to bring the shaft and the sleeve autonomously and automatically into a defined starting position. A medical arrangement includes at least the medical decoupling instrument and a medical insertion instrument.

A surgical instrument adaptor comprises a member including a first mating surface that is removably attachable with a surgical instrument and a second mating surface that is connectable with an actuator. An image guide is attachable with the member and oriented relative to a sensor to communicate a signal representative of a position of the surgical instrument. Systems, surgical instruments, spinal implants and methods are disclosed.

A receiver assembly for securing an elongate rod to a bone anchor includes a receiver having pair of upright arms that define an open channel configured to receive the elongate rod, a discontinuous helically wound receiver guide and advancement structure formed into the interior surfaces of the upright arms, and horizontally-elongated tool engaging grooves formed into upper portions of the outer surface of the upright arms. The receiver assembly further includes a closure configured for positioning within the open channel to secure the elongate rod to the receiver in a locked configuration, with the closure having an outer surface with a mating continuous helically wound closure guide and advancement structure configured to resist a tendency toward splaying between the upright arms upon a screwing in of the closure within the open channel by rotatable engagement with the receiver guide and advancement structure.

An inserter for attaching a modular yoke to a bone screw and for providing an indication of attachment, comprises a tubular body having a central lumen, distal and proximal ends, and an attachment portion for releasable attachment to a yoke having a bottom opening for receipt of a head of said bone screw. The inserter includes an inner shaft having a distal end configured to be received into the yoke, the shaft being axially movable within the lumen from first to second axial positions in response to the introduction of the bone screw head into the yoke bottom opening. An indicator button supported by the body is movable in response to axial movement of the shaft from a first indicator position indicating the first axial position of the shaft relative to the body to a second indicator position indicating the second axial position of the shaft relative to the body.

A fixation device includes a tapered cannula defining a bore therethrough, a shaft, and a post. The shaft includes a proximal portion disposed within the bore, and central and distal portions extending distally from the tapered cannula. The proximal portion includes a threaded inner surface defined therein. The shaft includes blades disposed within the central portion, the blades movable between a closed position in which the blades are disposed within the shaft and an open position in which the blades extend laterally through the shaft. The post includes a threaded outer surface threadingly engaged with the threaded inner surface of the shaft. The post is movable longitudinally within the shaft to transition the blades between the closed and open positions.

An energy transfer system includes a spinal implant having an antenna, an antenna extender attached to a portion of the spinal implant in proximity to the antenna, and a reader device configured to send energy to the spinal implant via the antenna extender. The antenna extender extends away from the spinal implant. The spinal implant is configured to be positioned within a spinal area of a patient.

A magnetic screw device that includes a fastening stem, a housing, a magnet assembly, and one or more magnets. The housing is configured to receive the fastening stem, such that the housing can rotate and angulate relative to the fastening stem. The housing is also configured to secure the magnet assembly. The magnet assembly contains two magnet holders that are each configured to receive one of the two magnets. The magnetic screw device can be used in a method of treating a spine with an abnormal curvature.

A stylet screw driver assembly having a screw driver/ratcheting handle assembly which houses a stylet, pre-assembled to a set length based on the screw length in use, fixed in place by a spring loaded button mechanism located on the proximal end of the ratcheting handle. The spring loaded button mates with the stylet assembly, providing various stylet protrusion lengths.

A pedicle screw system and methods of using same, the system including a pedicle screw with a screw head and a rod support housing with a head capture opening surrounded by relief slots. The rod support housing has an interior gripping ridge and an exterior locking groove. Pressing the screw head into the head capture opening results in regions of the rod support housing between the relief slots flexing outwardly to allow the screw head to pass over the gripping ridge, and the regions to cease flexing outwardly after the screw head is seated within the rod support housing. Pressing a locking ring over the head capture opening causes regions of the rod support housing between the relief slots to flex inwardly and allow a locking tab of the locking ring to pass into the locking groove, after which the regions cease flexing inwardly.

Systems and method of using a surgical driver instrument are provided. The driver instrument includes a driver shank having a proximal end including a head connector for a bone construct. The instrument includes an inner sleeve having a length and configured to receive the driver shank therein and a handle member having a first end and a second end. The inner sleeve and the driver shank have a non-threaded connection. The instrument includes an outer sleeve connected to the second end and concentric with the inner sleeve and a sleeve actuator assembly coupled to the handle member. The sleeve actuator assembly includes a first position where a portion of the length of the inner sleeve extends out from the handle member and a second position where the portion of the length of the inner sleeve that is extended from the handle member is retracted into the handle member.
