An angulating spinal plate assembly for fixation and/or support of bones of the spinal column is provided. The angulating bone plate includes interleaved, arcuate sheets that facilitate relative motion between first/second elements. An implant assembly is also provided that includes an angulating bone plate and associated first/second intervertebral plates that extend therefrom. The angulating bone plate generally includes an interleaved elements, e.g., an upstanding tab that cooperates with opposing faces of an opening, that permit rotational movement as between first/second implant elements until a desired relative orientation is achieved. At such time, a fixation/locking element is generally employed to fix the first/second implant elements relative to each other. The rotational movement permitted is generally in multiple planes based on the cooperative arcuate surfaces provided in the disclosed elements, i.e., side-to-side and top-to-bottom freedoms of movement.

A problem with total disc implant surgery appears to be the positioning of the implant which if not correct may lead to pain and eventually new surgery. The present invention relates to an improved disc implant for total disc replacement, that includes two inter-vertebral elements which are flexibly connected via a coupling mechanism. Following surgery, the relative movability of the two inter-vertebral elements is decreased overtime, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually decrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.

Method of spinal treatment

The present disclosure relates to the field of spine disc implants. Exemplary embodiments of the disclosed spinal disc implants advantageously and ultimately provide fusion with the body of the vertebra and stabilization of the spine in an anatomically correct position, e.g., in cervical, thoracic and/or lumbar regions. More particularly, the present disclosure is directed to a disc implant that addresses and overcomes the shortcomings of the prior implants by providing first and second inter-vertebral elements that are movably coupled relative to each other and are adapted to permit bone in-growth over time. Thus, the disclosed spinal disc implants permit relative movement between the first and second inter-vertebral elements upon implantation and after the patient is mobilized&#x2014;thereby permitting the implant to assume a desired position based on the specific and unique spinal balance of the patient in an initial post-implantation period&#x2014;but then the first and second inter-vertebral elements become fixed relative to each other (i.e., fused). The present disclosure also provides advantageous instrumentation and associated methods for positioning a spine disc implant in a desired anatomical location.

Spinal implant, instrument for preparation and method of use

A problem with total disc implant surgery appears to be the positioning of the implant which, if not correct, may lead to pain and eventually new surgery. The present invention relates to an improved disc implant () for total disc replacement, comprising two inter-vertebral elements () which are flexibly connected via coupling means (). Following surgery, the relative movability of the two inter-vertebral elements is decreased over time, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually decrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.

A problem with total disc implant surgery appears to be the positioning of the implant which if not correct may lead to pain and eventually new surgery. The present invention relates to an improved disc implant () for total disc replacement, comprising two inter-vertebral elements () which are flexibly connected via coupling means (). Following surgery, the relative movability of said two inter-vertebral elements is decreased overtime, as bone ingrowth occurring around the implant and specifically through osseointegrative sections gradually degrease the movability of the elements relative to each other. Following, the relative movability of the implant elements is replaced by fixation of the elements. The fixation has flowingly occurred in a position affected by the movement of the patient, and is thereby more acceptable to the patient.
