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 pedicle fixation system (10) may include a first fastener (12) and a second fastener (14). The first fastener (12) may include a first shank (40) extending along a first fastener axis (41) and a channel (52) extending along a skew axis (51). The skew axis (51) may be transverse to the first fastener axis (41) and the channel (52) may have a channel diameter perpendicular to the skew axis (51). The second fastener (14) may extend through the channel (52) and include a second shank (60) extending along a second fastener axis (63). At least a distal part of the second shank (60) may have a second fastener diameter perpendicular to the second fastener axis (63). The second fastener diameter may be smaller than the channel diameter.

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 compressor/distractor system for operating on a spine is disclosed. The system includes two rod reducers which each advance a spinal rod into the shoulder portion of a pedicle screw. Each rod reducer includes an inner member, an outer member, and a pair of gripping members. Each outer member receives and advances the spinal rod into the pedicle screw. The outer member also includes a through slot which receives the proximal end of each of the pair of gripping members which may limit the longitudinal translation of the outer member with respect to the inner member. The compressor/distractor system may include a compressor/distractor device which has a compressing, a distracting, and a neutral configuration. A method for using the minimally invasive rod reducers with the compressor/distractor system to secure at least two pedicle screws in desired positions on a spinal rod is also disclosed.

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 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 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.
