摘要:
The present application discloses intervertebral implants and methods of using the implants. The implants may include inferior and superior surfaces, and a sidewall that together form the body of the implant. An inner chamber is formed between the surfaces and the sidewall. An opening extends through the body to access the inner chamber. A cover plate is sized to extend across the opening. The cover plate is adjustable between an open position to access the inner chamber, and a closed position to prevent the bone growth material from escaping from the inner chamber.

Instruments and methods for cutting tissue are disclosed. The instruments include one or more cutting members movable from a reduced profile undeployed position for insertion to the operative site to a deployed position where the cutting members can be manipulated to cut tissue material at the operative site.
摘要:
A method and apparatus for determining, calculating, and/or viewing a trajectory. The trajectory can be displayed on a display relative to image data of a patient. A user can use the system to determine relationships between two or more trajectories that have been determined. The relationships can be within two dimensional, three-dimensional, or four dimensional space. The relationships can include distance, angle, etc. The relationships can also be determined between real time trajectories and stored trajectories, or combinations thereof.

Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another.

Devices, instruments, systems and techniques for guiding an implant to a location adjacent a bone anchor include a guide member with a connecting portion and a guiding portion. The connecting portion is adjacent the bone anchor, and the guiding portion extends proximally from the connecting portion and is adapted guide an implant therealong toward the bone anchor. The guiding portion is flexible to facilitate manipulation and implant placement in the patient's body.
