In a rod fixation system of the type used to treat various spinal conditions, the same fastener is used to lock both a polyaxial screw and a rod in position. A spinal correction device according to the invention, adapted for use with a rod and a polyaxial screw having a ball-shaped head and a threaded end, comprises a head-body and a cap. The head-body includes a lower internal cavity to receive the ball-shaped head of the screw, an upper bore to receive a fixation rod therethrough, and an upper end configured to receive the cap. The head-body and the cap are configured such that a first rotation of the cap locks the polyaxial screw in position, and a second rotation of the cap locks the rod in position. In the preferred embodiment, the head-body includes one or more gaps to facilitate flexion of the head-body as a rotational torque is placed on the cap. The gap or gaps may be horizontal, vertical or other angles relative to the axis of the entrapped rod.

The present disclosure provides a micro-flail assembly and associated method of use for the preparation of a nucleus/vertebral end cap of a spine. The micro-flail assembly is utilized in the formation of a nucleus/vertebral end cap between adjacent vertebrae while simultaneously protecting an adjacent annulus with a protective sheath. The protective sheath also acts as a guide while the micro-flail assembly is pivoted to form the end cap. Advantageously, the present invention can be utilized with a variety of surgical procedures including minimally invasive surgery. The formation of the end cap can be done in preparation of providing an insert device (e.g., bone graft, cage, artificial disc, or the like).

A bone-fastening system includes an implant with a threaded screw, a distal nut with a threaded bore, and a proximal washer which may also be threaded. An instrument for implanting the implant includes a handle and a barrel terminating in a holder for the washer. A c-shaped bridge assembly has a first end connected to the barrel and a second end including a holder for the nut in axial alignment with the washer. A manually operated control on the instrument, coupled to an elongated element in the barrel, causes the washer to move toward the nut, thereby applying compressive pressure to bone portions to be fastened together. A drive mechanism disposed within the barrel has a distal end with a holder for the screw and a proximal end that is turned by a user, thereby advancing the screw through the washer to the nut to fasten the bone portions under compression. The manually operated control is preferably a trigger that is squeezed toward the handle by a user. A separate control, also preferably in the form of a trigger, is used to release pressure on the elongated element in the barrel, enabling the implant to be easily removed from the implant once in position.

In one embodiment, a bone-fastening system includes a handle, a barrel assembly connected to the handle, and a bridge assembly connected to the barrel assembly. The bridge assembly may be configured to receive a first connector element and a second connector element in axial alignment with the first connector element so as to receive a fastening element between the first and second connector elements. The system may also include a control configured to, upon actuation, approximate the first connector element and the second connector element so as to apply compressive pressure to bone portions positioned between the first connector element and the second connector element. A drive mechanism configured to advance the fastening element through the bone portions and connect the first connector element with the second connector element to fasten the bone portions under compression may also be provided with the system.

The present disclosure provides systems and methods for retaining a plate, such as a cervical plate, to a substrate, such as bone, through a locking screw with upper asynchronous threads and lower cancellous threads. The present invention utilizes the locking screw with cancellous-type threads to draw the screw into the substrate. The screw is operable to retain a plate to the substrate and is configured to gall and lock to the plate through the upper threads which are out-of-phase with corresponding threads on the plate thereby preventing reverse threading or backing out of the screw.
