A method for treating a spine includes the steps of: creating a surgical pathway in a body along a first surgical approach to a surgical site including vertebral tissue; creating a surgical pathway in the body along a second surgical approach to the surgical site including the vertebral tissue; disposing a fulcrum with an intervertebral disc space of the vertebral tissue via the first surgical approach; and manipulating the vertebral tissue via the second surgical approach. Spinal implants, surgical instruments and systems are disclosed.

A joint implant to be mounted to a hard tissue of a patient comprises a body portion. The body portion having a tissue face configured to contact a prepared surface of the hard tissue of the patient, when the joint implant is mounted to the hard tissue of the patient. The tissue face of the body portion comprises an anchoring structure configured to anchor the joint implant on the hard tissue of the patient. The body portion is formed to fit the prepared surface of the hard tissue such that the joint implant is held in a predefined target position when mounted to the hard tissue

A method of seating a surgically implantable spacer including an upper and lower saddle member. The upper and lower saddles each having a first end and a second end. First and second expansion forces are applied to the first and second ends respectively causing equal separation until the first end encounters a resistive force, wherein a rate of separation between the first ends is reduced compared to rate of separation of the second ends. Vertebral contacting surfaces of the upper and lower saddle member can be arched, textured, or include any other feature to enhance an interface between the contacting surfaces and the vertebra.
