The BRYAN® cervical intravertebral disc replacement is a disc arthroplasty device comprising titanium and polyethylene components. It is indicated for intractable radiculopathy or myelopathy resulting from intervertebral disc disease or bulging. The BRYAN Cervical disc can be used to replace discs from C3-C7 and is intended to provide improved function and relief of neck pain.

Based on this knowledge, Dr Vincent Bryan developed his total cervical disc arthroplasty device in the 1990s. Dr Goffin of Belgium implanted this prosthesis for the first time in January 2000.,,, The aim of this review is to present the Bryan® Cervical Disc System (Medtronic Sofamor Danek; Memphis, Tennesse) and its use in the treatment of degenerative disc disease. Several types of cervical disc prostheses are marketed at present.,,

Bryan Artificial Cervical Disc - Neck Pain Explained

The standard surgical procedure for cervical degenerative disc disease or disc herniation has been in use for more than 50 years. It involves an anterior approach to the cervical spine and removal of the disc with the offending tissue (anterior cervical discectomy [ACD])., This procedure is safe in view of nerve decompression., However, ACD alone shows a tendency to create subsequent problems. The most notable are pain because of chronic instability or malalignment of the operated segment, as well as adjacent-segment disease.

If your surgeon cannot find a a reason to explain axial neck pain and suggests that you undergo discography, this might serve as a red flag that a cervical total disc replacement ultimately may not fix your underlying problem.

The DISCOVER Artificial Cervical Intervertabral Disc arthroplasty from Depuy is an unconstrained cervical disc prosthesis. The device is indicated for symptomatic cervical disc disease, with the aim of improving range of neck movement and reducing neck pain. The device comprises titanium alloy endplates coated with porous titanium spray and hydroxyapatite, and a central ultra high molecular weight polyethylene articulating core. It is available in a range of sizes and thicknesses.

METHODS: Eleven patients with symptomatic cervical radiculopathy underwent implantation of a radiostereometry modified Bryan prosthesis after a standard anterior cervical discectomy.

First, most surgeons believe that creation of an osseous block out of a functional motion segment has long-term adverse effects on adjacent segments below, and, more frequently, above, the block. Adjacent levels are subject to increased strain, motion, and intradiscal pressure (mechanical overcharge), as they have to take over the work of the fused segment.,–,,,,, Consequently, they tend to degenerate early. Elongation of the spondylodesis, including this pain-generating segment, is required later in many patients., Hilibrand et al reported an annual mean rate of 2.9% adjacent-segment disease during the first 10 years after operation; however, this value did not consider the inherent course of degeneration. Their Kaplan–Meier survivorship analysis of 374 fused patients revealed an incidence of 25.6% at 10 years. The risk of adjacent-segment disease was lowest for fusions at C2/3 and C6/T1, intermediate at C3/4 and C4/5 (factor 3.2), and highest at C5/6 and C6/7 (factor 4.9). In the long run, more than two-thirds of their patients who developed new transitional-segment disease needed further operations. They considered the inherent process of degeneration to be a more probable cause of adjacent-segment disease than increased stress after spondylodesis. Robertson et al found new symptomatic adjacent-disc disease after 158 fusions in 13.9% (6.9% annually) of patients at 2 years and considered transitional-level disease to be a sequela of spondylodesis. Goffin et al also reported a 92% incidence of radiologic adjacent-segment degeneration after ACDF (mean follow-up of 100.6 months, >60 months for all; mostly degenerative and trauma cases). However, only 6.11% (11 of 180) of patients eventually required surgery. Garrido et al analyzed three ACDF patients (12%) who underwent revision surgery for adjacent-segment disease within 48 months: one for remote-level degeneration and two for pseudoarthrosis formation, whereas only one (5%) had revision surgery in the Bryan cohort. There was a clear trend toward fewer secondary interventions in the Bryan group. Wigfield et al reported that fusion increased motion at adjacent levels.

SUMMARY OF BACKGROUND DATA: Cervical disc prosthesis is a motion-sparing technology in which the longevity is dependent on initial fixation as well as secondary fixation with bone ingrowth into the surface of the device.
