Method and a device for total spinal disc replacementMethod and a device for total spinal disc replacement description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20080119932, Method and a device for total spinal disc replacement. Brief Patent Description - Full Patent Description - Patent Application Claims Today the state of the art concerning total spinal disc replacement device insertion is the anterior approach, i.e. true anterior, anterolateral (oblique) or true lateral. The surgeon decides between transperitoneal or retroperitoneal approaches, depending on the treated level or his personal experience. However, due to the presence of major vessels (e.g. aorta, vena cava) the anterior approach to the spine is often performed in the presence of vascular surgeons thereby causing extra costs. In U.S. Pat. No. 6,719,794 GERBER a method for insertion of an intervertebral fusion implant is disclosed. The removal of the affected spinal disc as well as the insertion of the implant is performed via a posterior approach offset from the midline of the spine to the affected intervertebral disc. Disadvantageously, such a transforaminal approach includes a partial dissection of the facet joint. A prosthetic device for transforaminal insertion into an intervertebral space is known from US 2004/0225365 EISERMANN. This known prosthesis comprises two components having an articulating surface each in order to permit articulating motion between the first and second components and consequently of the adjoining vertebrae. The transforaminal path disclosed might cause potential damage to important anatomical structures such as nerve roots, dura, ligamentum flavum and interspinous ligaments. Therefore, it is an object of the present invention to provide a method for total spinal disc replacement device insertion including a dorsal approach to the spine without having to dissect the facet joint neither completely nor partially. According to the method of the present invention the above object is achieved by means of an extraforaminal approach including an access portal in the Fibrocartilago Intervertebralis between the anterior and posterior longitudinal ligaments for removing the affected intervertebral disc as well as for insertion of a total disc prosthesis. The method according to the invention offers the following specific advantages: A wide opening to the intervertebral space compared to true posterior or transforaminal approaches is achievable; The surgeon passes the neural structures and does not have to dissect the facet joint; The detection of the correct trajectory can be made with a visualisation of the Processus Transversus; The patient is in prone position as he would be for dorsal fixation procedures; and The surgeon is used to patient positioning and incisions. In a preferred embodiment the key element of the extraforaminal approach to the spinal disc is a path in front of the transverse processes (Processus Transversus). In a further embodiment the method further comprises the steps of: A) Performing a dorsal incision extra-medially, i.e. apart from the median longitudinal plane by targeting the Fascia Lumbodorsalis; B) Approaching the affected intervertebral disc with a Kirschner wire; C) Inserting along the Kirschner wire a trocar and a protection sleeve to the affected intervertebral disc;Continue reading about Method and a device for total spinal disc replacement...
