    Abstract: Orthopedic implant and methods of implantation for fixing adjacent bones. In one embodiment, the implant includes a locking mechanism that is adapted to be advanced by a locking instrument, wherein advancement of the locking mechanism in a first direction produces rotation of a first rigid abutment surface of the implant from a first orientation to a second orientation, and continued advancement of the locking mechanism produces advancement of the first rigid abutment surface towards a second rigid abutment surface of the implant. The continued advancement may also place a compressive load onto the implant sufficient to immobilize the implant relative to a first bony surface and a second bony surface.

    Abstract: A spinal fixation construct for aligning vertebral bodies includes a bone screw, a spinal rod, a flexible member, and a fixation member. The spinal rod is disposed within a saddle portion of a housing of the bone screw, and includes an elongated body having a first end and a second end. The spinal rod is formed from a first material having a first modulus of elasticity. The flexible member is coupled to the spinal rod, and includes an elongated body having a first end portion and a second end portion. The flexible member is formed from a second material having a second modulus of elasticity that is different from the first modulus of elasticity. The fixation member includes a threaded body portion and a head portion defining a hole therethrough. A portion of the flexible member extends through the hole of the head portion.

    Abstract: 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.
