摘要： Provided is a novel spinal fixation system that includes a novel multi-planar taper lock screw for connecting a connecting rod to bone as well as a novel locking device and a novel unlocking device, each being configured to selectively partially lock or fully the novel screw of the system. The screw is capable of multi-directional articulation while the connecting rod position can remain stable and aligned as needed. After the screw had been articulated and properly positioned, it can be locked such that the screw and the connecting rod will remain in relative position to the bone. The screw is configured for easy insertion and connection as well as easy removal and disconnection from the connecting rod. A method of fixing bones or bone fragments using the novel system is also provided.

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.

摘要： The present invention provides a novel minimally invasive surgical system and method for introducing instruments and/or biomaterial into the interior of a bone, particularly the interior of a vertebral body, using a unique cannulated screw that is sized and configured to penetrate the cortical bone and thereby provide access to the interior of the bone through the integral cannula of the screw. That same screw having a screw head that is then adaptable to employ a connector for securely holding a connecting device, such as a spinal rod or plate that can then be used to fix bones or bone fragments together. A method of fixing bones or bone fragments is also provided.

摘要： Devices, systems and methods for minimally open orthopedic spine surgery are disclosed. A first flexible screw-based retractor is designed to be coupled to each pedicle screw inserted into adjacent vertebral bodies. A retractor system is provided in which a first retractor blade is mounted to one of the screws and a second movable retractor blade is moved away from the first blade, in a medial direction, to create a working channel through which the disc space may be accessed for passing instruments and implants. Light may be incorporated into the device to illuminate the surgical field. One or all of the retractor blades may be made of a sterilizable plastic or metal and be disposable or reusable.

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.
