A medical or orthopedic implant, system and method for making the implant having areas that are designed to optimize compressive stress processing by, for example, laser shock peening. The implant is designed by identifying stress areas as processing zones. The processing zones are machined, processed or adapted to have a desired shape or configuration to optimize compression. The processed zones or areas are compressive stressed processed to have a higher density at zones or areas compared to areas that are not compressive stress processed. The implant is finished processed and sterilized and ready for use in the patient.

A system and method includes a housing dimensioned to be situated between adjacent spinal bones, such as adjacent vertebrae. Screws are provided in one embodiment and are dimensioned or configured to lock against each other to retain the screws and, consequently, the cover in place. Another embodiment illustrates a plurality of plate elements that can be slidably received and locked in the cage. Each of the plate elements are adapted to receive at least one screw and guide the screw at a predetermined angle into a vertebra, thereby securing the cage in an inter-vertebral space.

A modular interspinous fixation system and method are shown. The system and method comprise a first plate, a second plate and a locking cross bar for locking the first and second plates together and into locked engagement with a first spinous process and a second spinous process. A bridge is mounted or received on the locking cross bar so that it becomes locked onto the locking cross bar when the locking cross bar is in locked engagement. The bridge and locking cross bar are adapted so that the bridge does not rotate about its axis while on the locking cross bar. Various other embodiments are shown illustrating various bridges of different shapes and sizes, integral and non-integral locking cross bars and even a ramped locking cross bar for facilitating preventing separation of the first and second plates after they are mounted to the first and second spinous processes.

A surgical implant inserter compressor is shown having a plurality of jaws and is adapted to permit at least one or both jaws to move generally parallel with respect to each other or move along an axis wherein the jaws remain in a plane that is generally perpendicular to that axis. The surgical implant inserter compressor is adapted for implanting at least one or a plurality of plates onto a pair of spinous processes and is adapted to distribute the clamping force with which the implants engage the spinous processes. The surgical implant inserter compressor may be adapted to permit one or both jaws to float or pivot to accommodate different anatomical structures, such as spinous processes that are not aligned, are of different sizes or shape and the like. An optional tool guide for guiding a tool to drive a lock to lock the plates together is also shown.

A capless multiaxial screw fixation assembly, including: a screw having a threaded portion and a screw head portion positioned at one end thereof; and, a retainer having a first end, a second end opposite the first end, and a bore for receiving the screw threaded portion so that the screw head portion is seated therein. At least one of the screw and the retainer is configured such that the retainer is able to pivot about the screw head portion in a non-symmetrical manner.

Spinal fusion system and method utilizing an implant plate and screw, wherein at least one pawl is mounted on or integral with at least one of said plate and becomes operatively related to the screw after the screw is inserted in the implant plate to prevent the screw from moving in at least one of an axial direction or a rotational direction. Other features and embodiments are described and claimed.
