摘要： A bone fixation apparatus includes an insert and a bone anchor. The insert has open ends defining a lumen. A first thread is disposed on an outer surface of the insert and a second thread is disposed in the lumen. The insert is configured for threadably engaging bone. A driving tool is releasably attachable to the insert. The bone fixation apparatus also includes a bone anchor with a bone screw member and a housing. The bone screw member extends from the housing and has a third thread along a shank of the bone screw member. The third thread of the shank is engageable with the second thread of the lumen such that the bone anchor is coupled to the insert.

摘要： A modular screw includes a post and a head assembly. The post includes a tapered portion extending along a length of the post, the post defining a first bore. The head assembly is adjustably coupled with the post. The head assembly includes a head defining a slot configured to receive a spinal rod therein, an elongate screw having external threads extending along a length of the elongate screw, and a screw shank defining a second bore configured to receive the elongate screw therein. The screw shank includes an engaging portion configured to expand radially outward when the elongate screw engages the engaging portion, and internal threads configured to engage the external threads of the elongate screw. At least a portion of the screw shank is dimensioned to be selectively received in the first bore of the post.

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 modular screw includes a first assembly and a second assembly. The first assembly includes a base portion having a head portion, a securing portion defining a first bore, and a receiving portion defining a second bore. The second assembly includes a first post, a second post including an engaging portion, and an elongate screw threadably engageable with the second post. The second post is dimensioned to be received through the second bore of the receiving portion of the first assembly such that when a first set screw is received in the first bore, the first set screw secures the base portion of the first assembly to the second post. The elongate screw received in the second post causes radial expansion of the engaging portion of the second post, which, in turn, causes the engaging portion to be affixed to the cavity of the first post.

摘要： 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.

摘要： A fixation device includes a head, a tapered body coupled to the head and extending along a central longitudinal axis, and a flexible tail extending distally from the tapered body and defining a central bore therethrough. The flexible tail is movable from an initial configuration aligned with the central longitudinal axis to a deflected configuration that extends away from the central longitudinal axis when a force is applied to the flexible tail.

摘要： A fixation assembly includes a tapered cannula, a post, and a snap ring. The snap ring is attachable to the post and the tapered cannula. The snap ring is configured to maintain the tapered cannula axially fixed in relation to the post such that the tapered cannula and the post are rotatable relative to each other.
