摘要:
An artificial spinal disc that may be implanted between adjacent vertebrae in the spine to replace, repair or augment a natural spinal disc. The spinal disc implant is characterized by one or more biomechanical properties that approximate those of a natural spinal disc and is durable enough to function in the body for long time periods, amongst other advantages.

摘要:
An instrument for preparation of vertebral endplates and a method of preparing a surface of a vertebral endplate are described. The instrument includes a body having a frame, an endplate preparation member supported by the body, and a pivot point. A tilt axis is perpendicular to and intersects a sweep axis at the pivot point. The endplate preparation member is coupled to the frame and controllably pivotable in an arc about the first tilt axis to change a tilt of the endplate preparation member. The endplate preparation member is also controllably pivotable in an arc about the sweep axis while maintaining the tilt of the endplate preparation member. By sweeping the endplate preparation member at incrementally larger tilt angles, recesses in a vertebral endplate surface are gradually formed, which may allow greater precision and control of a depth of the recesses and reduce stress on the vertebral endplate, as opposed to more aggressive techniques.

Systems and methods for managing a health plan are described. In one embodiment, a method for managing a health plan includes presenting options for a health plan and an incentive program of the health plan, presenting options for configuring a health plan and an incentive program of the health plan, and receiving a selection of an incentive program. In other aspects, the method further comprises receiving a selection of a health plan and an incentive program, storing information about the selected health plan and incentive program, storing information regarding participation in the incentive program, and requesting a reward for a member for completion of the incentive program. In other aspects, the method may further include determining eligibility for an incentive program and a reward of the incentive program.
