The concept of accelerated degeneration of adjacent disc levels as a consequence of increased stress caused by inter body fusion of cervical spine is widely accepted. These phenomenon supports the hypothesis that reconstruction of an intervertebral disc after discectomy with functional disc prosthesis would offer benefit. Degeneration of an intervertebral disc involves progressive dehydration and fibrosis of the nucleus pulposus. These modifications induce loss of elasticity, loss of intervertebral height, formation of osseous spurs, cracking and bulging of the annulus fibrosus, and eventually, extrusion of nucleus tissue. Hence based on above findings the present study was planned for Assessment of Outcomes of Patients Undergoing Disc Preserving Functional Cervical Disc Surgery. The present study was planned in Department of Neurosurgery, SKMCH, Muzaffarpur, Bihar, India. Total 10 cases operated for cervical radiculopathy were enrolled in the present study. Diagnostic evaluation was performed by anterior posterior and lateral standard radiographs of the cervical spine and magnetic resonance imaging (MRI) evaluation of the cervical spine. All patients had follow up X-ray of the cervical spine anterior and posterior view with flexion and extension study, at 4 weeks and at subsequent follow up. The data generated from the present study concluded that the major symptoms experienced by the patients were neck and radicular pain. C6-7 cervical root level was affected in majority patients. Majority of the had an excellent surgical results. Post operative follow up X-ray after 6 months revealed adequate motion at the operated site.

Angle Change

Abstract Background. Dysphagia after cervical spinal surgery is one of highly prevalent comorbidities in clinical practice. Studies suggest that excessive O-C2 angle change at occipital-cervical fusion causes the oropharyngeal volume reduction leading to severe dysphagia and even respiratory distress after operation. However, rare study has accessed the impact of C2-C7 angle change on the occurrence of dysphagia after anterior cervical spinal surgery. Methods. From June 2007 to May 2010, A total of 198 patients was treated with anterior cervical decompression and plate fixation and 12 months follow-up was completed in 172 patients. Within the same session, a total of 154 patients underwent anterior cervical disc replacement and at least 1-year follow-up was completed in 98 patients. All 270 patients who participated in this study completed a questionnaire (Bazaz dysphagia questionnaire) after telephone follow-up including the onset and time of appearance of dysphagia, symptom relief, treatment plan and so on. To determine whether excessive cervical lordosis change (change of C2-C7 angle) and other risk factors were associated with the dysphagia symptom, all patients were divided into the dysphagia group and the control group, followed over 12 months.Results. The results showed that 12.8% presented with postoperative dysphagia in anterior cervical discectomy and fusion (ACDF) group and 5.1% in cervical disc replacement (CDR) group. According to the regression equation, the excessive change of C2-C7 angle can significantly increase the incidence rate of postoperative dysphagia. The incidence rate of postoperative dysphagia in patients whose C2-C7 angle change more than 5 degree was significantly greater than patients less than 5 degree. Sex, age, BMI, operation time, blood loss, surgery approach (anterior/posterior), revision ratio, the number of surgical segments, the highest surgical segment, and C3 segment included or not cannot affect the occurrence of dysphagia. Conclusions. Dysphagia after cervical spinal surgery is one of highly prevalent comorbidities. Cervical lordosis change is an important influencing factor on the occurrence of dysphagia after anterior cervical spine surgery.

Surgical Options

The surgical treatment of cervical spondylosis and resulting cervical radiculopathy or myelopathy has evolved over the past century. Surgical options for dorsal decompression of the cervical spine includes the traditional laminectomy and laminoplasty, first described in Asia in the 1970's. More recently the dorsal approch has been explored in terms of minimally invasive options including foraminotomies for nerve root descompression. Ventral decompression and fusion techniques are also described in the article, including traditional anterior cervical discectomy and fusion, strut grafting and cervical disc arthroplasty. Overall, the outcome from surgery is determined by choosing the correct surgery for the correct patient and pathology and this is what we hope to explain in this brief review.

OBJECTIVE Several large-scale clinical trials demonstrate the efficacy of 1- and 2-level cervical disc arthroplasty (CDA) for degenerative disc disease (DDD) in the subaxial cervical spine, while other studies reveal that during physiological neck flexion, the C4–5 and C5–6 discs account for more motion than the C3–4 level, causing more DDD. This study aimed to compare the results of CDA at different levels. METHODS After a review of the medical records, 94 consecutive patients who underwent single-level CDA were divided into the C3–4 and non-C3–4 CDA groups (i.e., those including C4–5, C5–6, and C6–7). Clinical outcomes were measured using the visual analog scale for neck and arm pain and by the Japanese Orthopaedic Association scores. Postoperative range of motion (ROM) and heterotopic ossification (HO) were determined by radiography and CT, respectively. RESULTS Eighty-eight patients (93.6%; mean age 45.62 ± 10.91 years), including 41 (46.6%) female patients, underwent a mean follow-up of 4.90 ± 1.13 years. There were 11 patients in the C3–4 CDA group and 77 in the non-C3–4 CDA group. Both groups had significantly improved clinical outcomes at each time point after the surgery. The mean preoperative (7.75° vs 7.03°; p = 0.58) and postoperative (8.18° vs 8.45°; p = 0.59) ROMs were similar in both groups. The C3–4 CDA group had significantly greater prevalence (90.9% vs 58.44%; p = 0.02) and higher severity grades (2.27 ± 0.3 vs 0.97 ± 0.99; p = 0.0001) of HO. CONCLUSIONS Although CDA at C3–4 was infrequent, the improved clinical outcomes of CDA were similar at C3–4 to that in the other subaxial levels of the cervical spine at the approximately 5-year follow-ups. In this Asian population, who had a propensity to have ossification of the posterior longitudinal ligament, there was more HO formation in patients who received CDA at the C3–4 level than in other subaxial levels of the cervical spine. While the type of artificial discs could have confounded the issue, future studies with more patients are required to corroborate the phenomenon.

Adjacent Segments

The range of movement(ROM) of adjacent segments and the change of intervertebral disc stress after implanting artificial cervical disc are investigated. The contact problem for bio-modeling is introduced. A normal cervical spine finite element model is proposed. The bone graft and fusion between C5 and C6 and C5/6 artificial disc implantation were simulated. The range of movement on adjacent segment and the change of intervertebral disc’s stress in such two cases are analyzed. Computational results show that the model includes the ligaments, joint capsule and other soft tissue structures, which is real, fine and high accuracy. When the adjacent intervertebral ROM was increased after interbody fusion surgery, the stress of corresponding intervertebral disc was increased obviously and the stress of upper segment of nucleus pulposus and annulus fibrosus were also increased about 70% ,besides the next-bit segments was increased about 40%. There were no differences among cervical spine ROM except extension (p> 0.05) after the implantation of artificial disc, and the stress on adjacent segments was increased less than 10%. The implantation of artificial cervical disc can release the stress on adjacent segments in a certain extent, and resume cervical activities at the same time.

OBJECTIVE: To quantify the mobility of the lower cervical spine after seven years of total cervical disc replacement at two levels. METHOD: This clinical study was designed randomly and prospectively at the spine surgery center at the Hospital Nossa Senhora das Graças, in Canoas, RS-Brazil and at the Hospital Don João Becker, in Gravataí, RS-Brazil. Seventeen patients were included in the study that was designed to compare the data obtained from annual and sequential manner until the end of seven years. A comparison was made with the prior range of motion (ROM) of each patient. All patients were diagnosed with not tractable symptomatic cervical degenerative disc disease with two adjacent levels between C-3 and C-7. RESULTS: A total of patients underwent TDR in two levels and at the end of seven years, only one patient was lost to follow-up. The pre and postoperative ROM was the same in the first three years however after the fourth year there was a gradual decline with a loss of 12% of preoperative ROM in flexion, 21% in extension and 23% in the right and left lateral bending at the end of seven years. CONCLUSIONS: The clinical outcome of this study is evidence level IV in evaluating the ROM for Moby-C(r) for TDR in two adjacent levels at the lower cervical spine. These results show that the ROM is maintained during the first three years, gradually declining after that.

This study aimed to observe dynamically the changes of x-ray, histomorphology appearance and serum inflammatory cytokines of cervical degenerative disease in rat models and to discuss the mechanism of cervical degeneration. Sixty Sprague Dawley rats were randomised into test ( n = 45) and control ( n = 15) groups, which were randomly subdivided into three groups corresponding to 1, 3 and 6 mo post operation. At the corresponding postoperative stage, cervical x-ray films were acquired, and intervertebral disc space and intervertebral foramen size were measured. Some serum inflammatory cytokines from all rats were quantitatively determined. Then, the morphological change in cervical intervertebral disc specimens stained with hematoxylin and eosin was observed. The results were analysed and compared among groups. Compared to the control group, the cervical x-ray and histomorphology appearance of rats in the test group showed varying degrees of degeneration. Furthermore, the serum IL-1β, TNF-α and IL-10 in the test group increased significantly at the corresponding postoperative stage ( P < 0.05, P < 0.01 and P < 0.001, respectively) compared to the control group. This model of cervical disc degeneration can accelerate imaging and histological degeneration, but it may be accompanied by changes in serum inflammatory cytokines levels.
