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 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 spinal implant has a proximal region and a distal region, and includes an upper body and a lower body each having inner surfaces disposed in opposed relation relative to each other. A proximal adjustment assembly is disposed between the upper and lower bodies at the proximal region of the spinal implant and is adjustably coupled to the upper and lower bodies, and a distal adjustment assembly is disposed between the upper and lower bodies at the distal region of the spinal implant and is adjustably coupled to the upper and lower bodies. The proximal and distal adjustment assemblies are independently movable with respect to each other to change a vertical height of at least one of the proximal region or the distal region of the spinal implant.

摘要： Provided is a surgical instrument having an adjustable distal end that can securely engage an interbody for introduction of the interbody into an intervertebral space, can be adjusted before and during the surgical procedure to vary the angle of the distal end of the device and the angle of introduction of the interbody, and after positioning that interbody at the surgical site, can be easily disengaged and removed.
