Military Patients

Numerous clinical and biomechanical evaluations of cervical disc replacement and anterior cervical discectomy and fusion as treatment of cervical disc herniation have been performed. Military patients represent a unique patient population as they may be subject to large external forces in theatre. Military patients are more susceptible to degenerative disease of the cervical spine, and if treated with single-level bony fusion, the treated level may be subject to large forces postoperatively. Literature reviews were conducted to determine patient outcomes following cervical disc replacement compared to bony fusion surgery; compare cadaver studies that evaluated the two conditions; and finite element modeling studies. In the civilian population, patients treated with each type of surgery have clinical improvement that is at least equivalent in the 2- and 5-year follow-up periods. Based on the finite element and cadaver biomechanical studies, semiconstrained devices, ProDisc-C and Prestige, are less mobile and a larger load is placed on the core of the device in comparison to the more mobile and unconstrained Bryan disc.

Cervical Disc Replacement

Anterior surgical approach is commonly used for Total Disc Replacement (TDR) surgeries in the cervical spine. The general procedure includes removal of the nucleus and anterior annulus of the intervertebral disc. Resection of Anterior Longitudinal Ligaments (ALL) is often performed to enter the disc space. The cervical spine also contains a unique anatomical feature called Luschka’s joints. These “joints” are actually fissures in the disc which run approximately parallel to the uncinate processes. These joints are thought to provide biomechanical stability to the cervical spine. However, sometimes surgeons have to sacrifice the uncinate processes at the involved level as well. We hypothesized that the cervical spine loses stability if the uncinate processes are removed along with disc replacement. We used a Finite Element (FE) model of cervical spine to prove the hypothesis (Fig1).
