摘要： A spinal hook includes a hook member, an inner collet, and an outer portion. The hook member includes a head portion and a blade portion. The inner collet includes a base portion configured to rotatably engage the head portion and a pair of engaging portions defining a slot configured to receive a connecting rod therein. The outer portion is movable relative to the inner collet between a locked position in which the outer portion causes the pair of engaging portions to move toward each other and an unlocked position in which the outer portion causes the pair of engaging portions to be spread apart to facilitate insertion or removal of the connecting rod.

摘要： A surgical rod scorer is provided. The surgical rod scorer includes a pair of elongated shaft members that are pivotably coupled to one another and movable from a spaced-apart configuration to an approximated configuration. Each of the shaft members includes a handle member that is configured for gripping by a user and jaw member that is configured to support respective first and second cutting assemblies thereon. The first and second cutting assemblies each include one or more cutting elements thereon configured and dimensioned to score surgical rod when the jaw members are in the approximated configuration and rotated about the surgical rod.

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： 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.

摘要： An expandable spinal implant configured for positioning within a space between adjacent vertebral bodies includes an upper body, a lower body, a ratchet mechanism, and a plurality of bone screws. The upper body and lower body are pivotably affixed at a first end and are capable of movement relative to each other. The ratchet mechanism is slidably disposed on one of the upper and lower body and is capable of engaging the opposite one of the upper and lower body thereby permitting movement of the upper and lower body relative to each other in a first direction, but not in a second direction. An insertion instrument capable of being attached to the expandable spinal instrument and a method of performing spinal surgery is also disclosed.

摘要： A retractor having a pair of blades is disclosed. A ring having an opening is attached to one end of the blades. The blades define a channel therebetween. The blades may be pivotally coupled to the ring. The retractor may have at least two conditions. In a first condition, the retractor is insertable through an incision in a patient's skin to an operative site. In a second condition, the retractor may be manipulated for retracting tissue surrounding the operative site. Instruments, prostheses, or tissue may be inserted or removed through the channel of the retractor.

摘要： A growing spinal rod system is configured to grow in response to the growth of a patient. The growing spinal rod system includes a housing, a spacer, and a sliding spinal rod. The housing includes a stepped passage therethrough. The spacer is disposed within the stepped passage and defines a through hole. The spacer includes a plurality of ribs biased inwards and into the through hole. The sliding spinal rod is slidably inserted through the through hole of the spacer. The sliding spinal rod moves the plurality of ribs outwards. The plurality of ribs permits the sliding spinal rod to extend from the housing and inhibit the sliding spinal rod from retracting into the housing.

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.
