Multiple level artificial disc implants

Lumbar total disc replacement is an effective treatment for single-level discogenic lower back pain. But Yanked bend wanked replacement of two disc levels is controversial. Two-level total disc replacement will improve function while preserving spinal motion. A continuous series of patients 51 women, 57 men surgically treated over two aartificial with the ProDisc-L implant Synthes Spine was evaluated retrospectively with an average follow-up of 4 ipmlants. The procedure was carried out through the left retroperitoneal approach in 65 patients, the right retroperitoneal approach in Multiple level artificial disc implants patients and both approaches in 1 Pantyhose sex pics best. The motion of the prosthetic disc segments was evaluated using Cobb's method. Data were collected prospectively in the context of regular patient monitoring. Multiple level artificial disc implants retrospective analysis was carried out by an independent examiner. The procedure led to a statistically significant Spyware for teens in the functional scores. Lack of mobility was not correlated with alterations in the functional outcome. Two-level lumbar disc replacement improves spinal function while preserving its mobility. But this procedure is Multiple level artificial disc implants with risks and must be carried out by a highly-experienced team. A artifickal follow-up is needed to evaluate the sustainability of the results and to detect any adjacent segment disease. Cookies are used by this site. For more information, visit the cookies page.

The approval in of an artificial disc to treat degenerative disc disease has had lots of people talking. It is a cure for back pain or just another high-tech, high priced gadget? The answer probably lies somewhere between. SpineUniverse spoke to several renowned and respected spine specialists about their opinions of this new technology. Read on to find out what these experts think. In my opinion, the artificial disc is the most revolutionary technology to hit spine surgery ever. It relieves pain while retaining motion, all without the need for fusion. It's easier on patients and the recovery is quicker. I am very encouraged. Disc replacement represents an exciting new treatment option for back pain associated with lumbar degenerative disc disease. There are a few potential concerns, however. While artificial discs appear safe when used in experienced hands, they are not for everyone. Patients with multi-level lumbar pathology are less likely to benefit than patients with one-level of lumbar disc degeneration. There are potentially serious operative risks that the patient needs to consider before opting for an artificial disc. No patient should consider this option without first trying high-quality non-operative treatments for at least six months. Patients should also be aware that the long-term outcomes of artificial discs are still not well-known and that revision surgery may be required down the road. Disc replacement is the most significant advancement since the modern treatment of spinal disorders began 70 years ago. Further, disc replacement introduces a new era of motion preserving surgeries that will include facet joint replacement, nucleus replacement, and minimally invasive motion preservation devices. The lives of millions of patients will change for the better. To see patients who have suffered with chronic back pain for years only to return to normal pain free lives is truly amazing. But...

While ACDF is generally successful at reducing pain and neurological symptoms, patients are left with decreased range of motion in the neck. Moreover, fusion creates abnormal loads and stresses on the spine, particularly on vertebrae adjacent to the treated levels. These abnormal stresses tend to accelerate degeneration of adjacent discs. Artificial vertebral disc replacement is emerging as an attractive alternative to ACDF. The principal benefit of total disc replacement TDR from the patient's perspective is that it preserves freedom of motion in the cervical spine. A meta-analysis of 19 clinical trials including 4, cases showed cervical disc replacement resulted in better functional outcomes, fewer adverse events, and fewer surgical revisions and reoperations than ACDF. These findings mirror my clinical experiences with cervical disc replacement. While the cervical disc replacement surgery takes a bit longer and is more technically challenging than ACDF, patient outcomes are undoubtedly better. My TDR patients tend to recover more quickly after surgery, have substantially better range of motion, and better long term outcomes than myACDF patients. This is especially true in two-level disease. The major reason for this reluctance, I believe, is the relative novelty of TDR in cervical disc disease. Artificial discs have only been approved for use in the cervical spine in the United States since Their history in cervical disc disease is even shorter, and their history as a two-level treatment in multilevel cervical disease is shorter still. This reluctance to move toward TDR may soften as clinical trial data with longer endpoints are published. The results from replacement at two adjacent levels are particularly compelling. I was one of the investigators who participated in the investigational device exemption IDE trials. The work was performed at 30 surgical centers in the United States on spine surgery candidates with multilevel cervical disc disease...

In this study, the authors review the technique for inserting the Prestige ST in a contiguous multilevel cervical disc arthroplasty in patients with radiculopathy and myelopathy. They describe the preoperative planning, surgical technique, and their experience with 10 patients receiving a contiguous Prestige ST implant. They present contiguous multilevel cervical arthroplasty as an alternative to multilevel arthrodesis. After institutional board review approval was obtained, the authors performed a retrospective review of all contiguous multilevel cervical disc arthroplasties with the Prestige ST artificial disc between August and November at a single institution by a single surgeon. Clinical criteria included patients who had undergone a multilevel cervical disc arthroplasty performed for radiculopathy and myelopathy without the presence of a previous cervical fusion. Between August and November , patients underwent cervical arthroplasty. The multilevel cervical arthroplasty group consisted of 14 noncontiguous and 10 contiguous implants. This paper examines patients who received contiguous Prestige ST implants. Ten men with an average age of 45 years range years were treated. Five patients presented with myelopathy, 3 presented with radiculopathy, and 2 presented with myeloradiculopathy. Six patients received 2-level Prestige ST implants. Three patients 2 with 3-level disease and 1 with 4-level disease received contiguous Prestige ST implants as well as a Prevail ACDF as part of their constructs. The mean clinical and radiographic follow-up was 12 months. There has been no case of screw backout, implant dislodgment, progressive kyphosis, formation of heterotopic bone, evidence of pseudarthrosis at the Prevail levels, or development of symptomatic adjacent level disease. Multilevel cervical arthroplasty with the Prestige ST is a safe and effective alternative to fusion for the management of cervical radiculopathy and myelopathy.

Cervical disc replacement CDR has been developed as an alternative surgical procedure to anterior cervical discectomy and fusion ACDF for the treatment of single-level cervical degenerative disc disease. A meta-analysis was performed for articles published up until August Two reviewers independently screened the articles and data following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. The rate of adverse events was significantly lower in the CDR group. However, there is insufficient evidence to draw a strong conclusion due to relatively low-quality evidence. Future long-term, multicenter, randomized, and controlled studies are needed to validate the safety and efficacy of multilevel CDR. During the past decades, anterior cervical discectomy and fusion ACDF has been the most accepted surgical procedure for symptomatic cervical disc disease with satisfactory clinical outcomes. Although the procedure is very safe and effective in terms of resolving symptoms, maintaining cervical stability and restoring cervical lordosis are challenging. Fusion sacrifices the motion of the operated level, which may result in increased intradiscal pressure, hypermobility at adjacent segments, and gradual development of adjacent segment degeneration ASD according to biomechanical studies, especially in MCDDD. Single-level CDR has been used in clinical practice and has obtained similar or superior outcomes compared with ACDF for the treatment of symptomatic cervical degenerative disc disease as evidence by an accumulation of some mid- and a few long-term studies. Additionally, some surgeons are concerned about lower motion quality resulting from imperfect prosthesis position and endplate-device matching might amplify the adverse effect of CDR. Previous meta-analysis reviews have mainly concentrated on comparisons between single-level CDR and single-level fusion. The purpose of this study was to compare the clinical and radiological outcomes of multilevel CDR with multilevel ACDF and to preliminarily evaluate the safety and efficacy of multilevel CDR. Electronic literature databases, including PubMed, Cochrane Central...
