A spinal fixation device includes a housing defining a chamber and a longitudinal axis, and an end plate assembly operatively coupled with the housing. The end plate assembly includes a first end plate configured to engage a vertebral body and first and second support assemblies operatively coupled to the first end plate. The first support assembly is selectively movable between a first position in which the first end plate is spaced apart from the housing and a second position in which the first end plate is adjacent the housing. The second support assembly is transitionable between a first state in which the first end plate has a first angular orientation and a second state in which the first end plate has a second angular orientation.

A surgical access system includes a connector including an arm, a coupling element, a rod, and a ridged slider. The arm includes first and second notched sections disposed in opposed lateral sides thereof. 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.

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.

A spinal fixation device includes an outer housing and an end plate assembly coupled with the outer housing. The outer housing defines an aperture and a longitudinal axis. At least a portion of the end plate assembly is slidably received within the outer housing. The end plate assembly includes a first end plate configured to engage a vertebral body, wherein the end plate assembly is selectively movable between a first position in which the first end plate is spaced apart from the outer housing and a second position in which the first end plate is adjacent the outer housing. Further, the first end plate is selectively adjustable to an angular orientation of a plurality of angular orientations with respect to the longitudinal axis of the outer housing.

A spinal rod locking holder includes an outer body, a handle assembly at a proximal end of the outer body, a locking assembly within a distal portion of the outer body, and a sprocket assembly at the distal end of the outer body. The handle assembly includes a moveable handle operatively associated with the sprocket assembly to selectively engage and release an end of a spinal rod. The locking assembly including a bearing operatively associated with a pawl such that when the moveable handle is compressed the bearing extends the pawl into contact with an outer surface of the sprocket assembly. The sprocket assembly including sprocket sections configured to compress against the end of the spinal rod when the pawl engages the outer surface of the sprocket assembly.

An adjustable spinal implant includes a lower body, an upper body, a locking pawl, and a locking key. The upper body and the lower body are pivotable relative to one another between a collapsed position and an expanded position. The upper body includes a locking flange that extends towards the lower body. The locking pawl is coupled to the lower body and is moveable between a locked position such that the upper and lower bodies are fixed relative to the one another and an unlocked position such that the upper and lower bodies are moveable relative to one another. The locking key is moveable between a locked state such that the locking pawl is fixed in the locked position and an unlocked state wherein the locking pawl is moveable between the locked position and the unlocked position.

A system for securing a flexible member to a vertebra includes a flexible member, a fixation member, and an inserter. The flexible member includes two ends. The fixation member includes a head and a shank that defines a longitudinal axis of the fixation member. The head defines a slot that passes through the head orthogonal to the longitudinal axis. The slot receives a portion of the flexible member. The inserter includes a handle and a tubular member that has proximal and distal end portion. The proximal end portion is attached to the handle and the distal end portion extends from the handle. The tubular member defines a passage between the proximal and distal end portions. The distal end portion includes a couple for receiving the head of the fixation member with the portion of the flexible member received in the slot of the flexible member.
