摘要: A system for forming a spinal prosthesis in situ within an intervertebral space located between first and second adjacent vertebrae includes at least one mold having at least one internal compartment adapted to receive at least one flowable biomaterial. The system also includes a retaining member adapted to secure the mold between the first and second vertebrae, the retaining member including first and second portions adapted to be engaged with first and second surfaces of the first and second vertebrae, respectively. The retaining member also includes an intermediate body operatively coupling the first portion to the second portion, the intermediate body adapted to be positioned in or adjacent to the intervertebral space. A biomaterial delivery apparatus is in fluid communication with the mold at a pressure sufficient for the mold to engage with the retaining member. The spinal prosthesis selectively position the first vertebrae relative to the second vertebrae.

摘要: An artificial spinal joint, consisting of a flexible or rigid member or a pair of moveably-joined, flexible or rigid segments, is formed into a spring-like shape, whose distal ends have feet with slots through which screws can be inserted to attach the artificial joint to vertebra whose facets (joints) are non-functional. The artificial spinal joint is able to prevent subluxation of the spine, while retaining the mobility of the spine and permitting angular deflection of the vertebra above and below a non-functional spinal joint. A jig is used to position tools and make passageways for screws to attach the artificial spinal joint to the vertebra or its pedicles or facets in a minimally invasive procedure. The rigid members or segments are bio-compatible and may be made of titanium, a titanium alloy, tantalum, medical grade stainless steel or carbon fibers in a matrix of a rigid, durable plastic. The flexible members or segments may be made of spring steel coated with a durable, bio-compatible material, small diameter carbon fibers in a flexible, durable plastic matrix, or a single shape or dual shape, superelastic memory metal. The feet, made of any of the rigid or flexible materials described above, may also be moveably attached to the proximal ends of the members or segments. Having the feet moveably attached to the segments facilitates insertion of the artificial spinal joint into the body by folding the feet parallel to the axis of the segments during insertion, and then unfolding the feet for attachment to the vertebra or its pedicles or facets. The artificial spinal joint may be inserted and attached to vertebra whose facets are non-functional in minimally invasive, moderately invasive or conventional surgical procedures.
