摘要：
A method for fusing vertebral bodies comprising the steps of: mounting a first engagement member of a fixation member to a pedicle of a first vertebra and a second engagement member of the spinal fixation member to a pedicle of a second vertebra, the first engagement member having a first extension engaged with an expansion ring, the second engagement member having a second extension engaged with the expansion ring inserting screws through the first and second engagement members and into the pedicles of the respective first and second vertebrae rotating the expansion ring in a first direction, thereby distracting the first and second vertebrae implanting an intervertebral implant between the first and second vertebrae after rotating the expansion ring in the first direction and rotating the expansion ring in a second direction after implanting the intervertebral implant, thereby compressing the first and second vertebrae.
