Because the approach for bryan cervical disc replacement is identical to that of anterior cervical discectomy (acd) and cervical arthroplasty with any type of cervical prosthesis, the complications related to operative approach are similar. The bryan cervical artificial disc is unique in that there is a flexible membrane that surrounds the nucleus (the inner portion of the disc) that is filled with a lubricant this membrane is designed for two purposes: to contain any wear debris that forms and to prevent any soft tissue in-growth. Patients with symptomatic cervical radiculopathy and/or myelopathy underwent implantation with the bryan prosthesis after a standard anterior cervical discectomy at scheduled follow-up periods, the effectiveness of the device was characterized by evaluating each patient's pain, neurological function, and range of motion at the implanted level.
The bryan® cervical disc prosthesis is at the forefront of cervical arthroplasty and is available today however, many questions about cervical disc replacement remain to be answered and include the effect to adjacent spinal levels and the device's longevity. Day 3-4 post surgery c5-c6 arthroplasty with bryan cervical disc implant. In both traditional disc surgery and artificial disc replacement, the procedure begins by removing the gelatinous disc between the vertebrae bryan® cervical artificial disc the surgical procedure to implant a bryan® cervical artificial disc is similar in approach and technique to traditional cervical spine surgery that has been used for more. Study design: in vitro wear testing of the bryan cervical disc prosthesis was performed in a cervical spine simulator the biologic response was assessed in chimpanzee and goat animal models objective: determine the wear characteristics of the bryan disc.
All patients received either a single-level fusion with allograft and anterior cervical plate (atlantis anterior cervical plate, n=13) or a single-level artificial cervical disc (bryan cervical disc prosthesis, n=9) at either c5/c6 or c6/c7. Our medtronic bryan cervical disc may be the answer to eliminating your pain features of the bryan disc include titanium alloy shells, cp titanium porous coating, polyurethane inner nucleus, and. Description of the bryan cervical disc the prosthesis design isbased on a proprietary, low-friction, wear-resistant, elastic nucleus the nucleus is located between, and articulates with, two shaped titanium plates (shells) that are aﬃxed to the vertebral body endplates and provide for.
Intervertebral disc prostheses aetna considers fda‐approved prosthetic intervertebral discs (eg, bryan cervical disc, mobi‐c, the prestige cervical disc, prodisc‐c total disc replacement, secure‐c artificial cervical for a single‐level artificial disc prosthesis or 2 contiguous levels. The bryan ® cervical disc is indicated in skeletally mature patients for reconstruction of the disc from c3-c7 following single-level discectomy for intractable radiculopathy and/or myelopathy the bryan ® device is implanted via an open anterior approach. 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. Abstract: the early clinical results with the bryan cervical disc prosthesis are encouraging but 2 recent small published series have noted postoperative radiologic kyphosis of the functional spinal unit (fsu) of 4 and 6 degrees.
A clinical analysis of 4- and 6-year follow-up results after cervical disc replacement surgery using the bryan cervical disc prosthesis j neurosurg spine 2010 12(3). The bryan cervical disc was originally conceived and developed by seattle-based neurosurgeon dr vincent bryan and alex kunsler, a local mechanical engineer experienced in designing medical devices in 1993, they founded spinal dynamics, inc, and initiated the development of the bryan cervical disc system. Cervical disc arthroplasty has emerged as a promising potential alternative to anterior cervical discectomy and fusion (acdf) in appropriately selected patients despite a history of excellent outcomes after acdf, the question as to whether a fusion leads to adjacent segment degeneration remains. Many short- and intermediate-term radiological and clinical studies on cervical arthroplasty with the bryan cervical disc have been published, providing, most of the time, satisfactory results.
The aramis cervical intravertebral disc prosthesis is intended for use in the cervical spine it comprises two cobalt chrome plates with an interposing bearing made of a carbon fibre/peek composite the device aims to restore disc height and movement in the spine and reduce neck pain. Mobi-c cervical disc is an fda approved artificial cervical disc for one and two level disc replacement and helps those with degenerative disc disease maintain neck mobility unlike fusion procedures, mobi-c implants fits entirely within the disc space and attempts to maintain neck movement. Bryan cervical disc prosthesis (investigational group) preoperative imaging studies included plain radiographs, magnetic resonance imaging, and computed tomography. Early results have indicated that the bryan cervical total disc replacement (tdr) favorably compares to anterior cervical decompression and fusion, while it is associated with fewer complications and higher levels of satisfaction.
Methods the implant employed throughout this study is the bryan cervical disc prosthesis (medtronic sofamor-danek) this comprises a closed unit with polyethylene articular surfaces, bonded to a titanium shell, enclosed in a polyurethane membrane. Figure 43–5 bryan cervical disc prosthesis is shown ex vivo and in unassembled form the endplates of this device are unique in their design and promote ingrowth of bone into metallic surface the endplates of this device are unique in their design and promote ingrowth of bone into metallic surface. T he inclusion of patients for the first prospective multicenter trial using the bryan cervical disc prosthesis (medtronic) for the treatment of patients with single and bilevel degenerative disc disease of the cervical spine was initiated in europe on january 5, 2000, and was concluded in april 2001.
Technology an artificial disc is a prosthetic device inserted between the vertebrae to replace a natural spinal disc when non-surgical therapies fail to provide relief, artificial disc replacement surgery may be an option your doctor recommends. Objective: therefore, we asked whether the 1) clinical and 2) radiographic outcomes of bryan cervical disc prosthesis were better than that of anterior cervical discectomy and fusion (acdf) at single site, and whether the 3) occurrences of heterotopic ossifications (hos) were associated to the function loss in the long-term follow-up. Cervical artificial discs are still a relatively newer technology previously, it was common for patients experiencing cervical degenerative disc disease and other cervical disc conditions to receive a cervical spinal fusion, typically an anterior cervical discectomy and fusion (acdf. Total disc arthroplasty is a new option in the treatment of cervical degenerative disc disease several types of cervical disc prostheses currently challenge the gold-standard discectomy and fusion procedures this review describes the bryan cervical disc system and presents the bryan prosthesis.
