摘要： A modular pedicle screw for spinal fixation. The pedicle screw includes a bone screw and a modular head assembly. The bone screw having a head and a shank, the head defining at least one groove. The modular head assembly includes a housing having a proximal end, a distal end and a throughbore extending along a longitudinal axis of the housing between the proximal and distal ends of the housing, and an anvil disposed within the throughbore. The modular head assembly includes at least one protrusion sized and shaped to be received by the at least one groove for restricting relative movement between the housing and the bone screw to a single plane.

摘要： A surgical tool for use with a drill bit to prevent skiving at an implant insertion site on a bone includes a cannulated sleeve having a distal end defining a burr surface. The distal end may be detachable from a body of the cannulated sleeve. The tool may be used with more than one distal end, each of the distal ends defining a burr surface having a different cutting surface from the others. The tool may form a system that includes the drill bit.

The coupling element includes a body section defining an opening therethrough, and opposed tabs protruding therefrom that are configured to receive the second notched section therebetween such that the arm is pivotably coupled to the coupling element. The rod includes a shaft having a plurality of angled grooves defined partially along a length thereof. The rod extends through the opening of the coupling element and the first notched section of the arm. The ridged slider includes a first surface having a plurality of ridges extending along a partial length thereof. The ridged slider extends through the coupling element with the plurality of ridges operably engaged with the plurality of angled grooves of the rod.

摘要： In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

摘要： A fixation device includes an outer member, an inner member, and an expansion member. The outer member includes an elongated body portion and a slotted tail portion, and defines a central bore therethrough that extends along a central longitudinal axis. The inner member is disposed within the central bore of the outer member, and the expansion member is coupled to the inner member. Proximal movement of the inner member relative to the outer member moves the expansion member into the slotted tail portion of the outer member such that the slotted tail portion moves from an undistended configuration to a distended configuration.

摘要： A surgical instrument includes a body, a securement arm, a clamp lock, and a tensioning assembly. The body defines a longitudinal axis and has proximal and distal portions. The distal portion defines a recess. The securement arm is coupled to the body and translatable along the body in a direction parallel to the longitudinal axis between first and second position. The clamp lock is pivotally coupled to the distal portion of the body. The clamp lock is pivotable between secured and unsecured configurations. The tensioning assembly translatable in a direction parallel to the longitudinal axis between proximal and distal position. The tensioning assembly configured to draw a flexible band to tension the flexible band about a bony element.

摘要： Devices, systems and methods for minimally open orthopedic spine surgery are disclosed. A first flexible screw-based retractor is designed to be coupled to each pedicle screw inserted into adjacent vertebral bodies. A retractor system is provided in which a first retractor blade is mounted to one of the screws and a second movable retractor blade is moved away from the first blade, in a medial direction, to create a working channel through which the disc space may be accessed for passing instruments and implants. Light may be incorporated into the device to illuminate the surgical field. One or all of the retractor blades may be made of a sterilizable plastic or metal and be disposable or reusable.

摘要： A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing. The anvil is positionable within the housing adjacent to the head of the bone screw member when the anvil and the head of the bone screw member are positioned within the housing. The anvil may define one or more grooves in an outer surface of the anvil. The groove defines a flap that is flexibly attached to the anvil to enable the anvil to flex an amount sufficient to maintain the head of the bone screw in constant contact with the anvil when the bone screw member is moved relative to the anvil. A rod reducer may be secured to the polyaxial pedicle screw to secure a spinal rod within the housing.

摘要： A spinal fixation device is provided including a modular head assembly and a bone screw. The modular head assembly includes a housing, an anvil, an insert, and a snap ring. The housing defines a proximal surface and an opposite, distal surface, and the proximal and distal surfaces define a throughbore therethrough. The anvil is configured to be slidably received within a portion of the throughbore. The insert defines a proximal surface and an opposite, distal surface, and the distal surface defines a first counterbore therein that terminates at a first annular surface. The first annular surface defines a second counterbore that terminates at a second annular surface. The snap ring is configured to be disposed within the first counterbore of the insert when in a first configuration, and within the second counterbore of the insert when in a second configuration.

摘要： Disclosed are systems and methods for rapid generation of simulations of a patient's spinal morphology that enable pre-operative viewing of a patient's condition and to assist surgeons in determining the best corrective procedure and with any of the selection, augmentation or manufacture of spinal devices based on the patient specific simulated condition. The simulation is generated by morphing a generic spine model with a three-dimensional curve representation of the patient's particular spinal morphology derived from existing images of the patient's condition.
