Background. The transverse skin incision for anterior cervical spine surgery is not extensile, thus it must be made at the accurate level. The use of palpable bony landmarks is unreliable due to anatomical variations and pre-operative fluoroscopy to identify the level takes up operating room time, increases the radiation dose to the patient and increases the overall cost of the operation. Objective. To describe a simple, fast and inexpensive method of accurate transverse skin incision placement for anterior cervical spine surgery and to report on its use in 54 consecutive adult patients. Patients and Methods. In each case a ratio was recorded on the lateral cervical spine radiograph based on the distance between the clavicle and mandible and the operative level; this was then applied to measurements on the patient's neck. Results. Procedures performed consisted of a mix of discectomy and fusion, disc replacement and combinations of both. The operative level ranged from C2-C3 to C7-T1, the most common being C5-C6. Twenty-three patients had a single-level, 26 a two level and 5 a three level procedure; all cases were performed through one single transverse incision. Conclusion. We describe the highly successful use of a straightforward method for accurate level transverse skin incision placement for cervical spine surgery In no case was it necessary to radically extend or to make a separate incision. There were no cases where the wrong level was operated on

There is evidence that preoperative physical fitness impacts surgical outcomes, specifically preceding abdominal, cardiovascular and spine surgery. To our knowledge, there are no papers on self-reported exercise frequency as a predictor of cervical spine surgery outcomes. Our objectives were to quantify self-report of exercise frequency in cervical spine surgery patients, and to elucidate if self-reported exercise prior to surgery confers less pain, improved health state and/or less disability post-surgery. We performed a retrospective review of prospectively collected data from the Canadian Spine Outcomes and Research Network (CSORN) Database from the time of its inception. Inclusion criteria specified all elective cervical surgery patients over 18 years old with degenerative pathology who proceeded to surgery and completed the pre- and post-operative outcomes measures up to 24 months post surgery (n=460). Outcome measures were visual analog scales (VAS) for neck and arm pain, Neck Disability Index (NDI), and EuroQOL score at baseline and 3, 12 and 24 months post-op. Exercise frequency was self-reported as “none” (n=212) versus “some” (n=248). These groups were further categorized into “none due to physical limitations”, “none” (not due to physical limitations), those to exercised “once or less per week” and those that exercised “twice or more per week”. Student's t-tests were used to compare the mean scores of the outcome measures, and analysis of variance for subgroup comparisons, with results considered significant at p < 0 .05. At baseline, 56% of total patients reported exercise prior to surgery, of which 73% reported doing so twice or more per week. Of the 44% reporting no exercise, 74% could not exercise due to physical limitations. Those who reported “some” exercise had more favorable VAS neck and arm pain scores pre-operatively (neck: 5.55 vs 6.11, p < 0 .001) (arm: 5.69 vs 6.04, p=0.011), but no difference at 3 and 24 months post-operatively. Significantly lower NDI scores and higher EuroQOL Index scores were seen in the exercise group compared to the no exercise group pre-operatively (NDI: 39 vs 48, p < 0 .001) (EuroQOL: 0.60 vs 0.50 p < 0 .001) as well as at 3, 12, and 24 months post-op (NDI: 24 vs 31, p=0.007) (EuroQOL: 0.75 vs 0.68, p=0.001). Further subgroup analysis demonstrated that compared to the “no exercise due to physical limitation” group, the “twice or more” exercise group showed favorable NDI and EuroQOL scores up to 24 months post-op (NDI: 24.32 vs 32.33, p=0.001) (EuroQOL: 0.76 vs 0.66, p=0.001), whereas the “once or less times per week” group no longer demonstrated any significant difference at 24 months (NDI: 28.79 vs 32.33, p=1) (EuroQOL: 0.73 vs 0.66, p=0.269). Self-reported exercise prior to cervical spine surgery does not predict improved long-term neck and arm pain at 2 years post-op. However, self-reported exercise does demonstrate less disability and improved health state at baseline and up to 2 years post-op and this relationship is dose dependent

Resident involvement in the operating room is a vital component of their medical education. Conflicting and limited research exists regarding the effects of surgical resident participation on spine surgery patient outcomes. Our objective was to determine the effect of resident involvement on surgery duration, length of hospital stay and 30-day post-operative complication rates. This study was a multicenter retrospective analysis of the prospectively collected American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. All anterior cervical or posterior lumbar fusion surgery patients were identified. Patients who had missing trainee involvement information, surgery for cancer, preoperative infection or dirty wound classification, spine fractures, traumatic spinal cord injury, intradural surgery, thoracic surgery and emergency surgery were excluded. Propensity score for risk of any complication was calculated to account for baseline characteristic differences between the attending alone and trainee present group. Multivariate logistic regression was used to investigate the impact of resident involvement on surgery duration, length of hospital stay and 30 day post-operative complication rates. 1441 patients met the inclusion criteria: 1142 patients had surgeries with an attending physician alone and 299 patients had surgeries with trainee involvement. After adjusting using the calculated propensity score, the multivariate analysis demonstrated that there was no significant difference in any complication rates between surgeries involving trainees compared to surgeries with attending surgeons alone. Surgery times were found to be significantly longer for surgeries involving trainees. To further explore this relationship, separate analyses were performed for tertile of predicted surgery duration, cervical or lumbar surgery, instrumentation, inpatient or outpatient surgery. The effect of trainee involvement on increasing surgery time remained significant for medium predicted surgery duration, longer predicted surgery duration, cervical surgery, lumbar surgery, lumbar fusion surgery and inpatient surgery. There were no significant differences reported for any other factors. After adjusting for confounding, we demonstrated in a national database that resident involvement in surgeries did not increase complication rates, length of hospital stay or surgical duration of more routine surgical cases. We found that resident involvement in surgical cases that were generally more complexed resulted in increased surgery time. Further study is required to determine the relationship between surgery complexity and the effect of resident involvement on surgery duration

Cervical total disc replacement has been in practice for years now as a viable alternative to cervical fusion in suitable cases, aspiring to preserve spinal motion and prevent adjacent segment disease. Reports are rife that neck pain emerges as an annoying feature in the early postoperative period. The facet joint appears to be the most likely source of pain. 50 patients were prospectively followed up through 5 years after having received disc replacement surgery, indicated for symptomatic soft disc herniation of the cervical spine presenting with radiculopathy. • All were skeletally mature and aged between 22 to 50. • All had failed a minimum of 6 months conservative therapy. • Up to 2 disc levels were addressed. C3 till C7 levels. • Single surgeon (first author). • NDI > 30% (15/50). • Deteriorating radicular neurology. We excluded those with degenerative trophic changes of the cervical spine, focal instability, trauma, osteoporosis, previous cervical spine surgery, previous infection, ossifying axial skeletal disease and inflammatory spondyloarthritides. The device used was an unconstrained implant with stabilizing teeth. Over the 5 years, we studied their postoperative comfort level via the Neck Disability Index (NDI) and Visual Analogue Score (VAS). Pre-operative and post-operative analysis of the sagittal axis and of involved facet joints were done. 22 patients suffered postoperative neck pain as reflected by the NDI and VAS scores. Of these, 10 reported of neck pain even 24 months after surgery. However, none were neurologically worse and all patients returned to their pre-morbid functions and were relieved of pain by 28 months. All 22 patients reported of rapid dissolution of neckache after peri-facetal injections of steroids were done under image guidance. We draw attention to the facet joint as the pain generator, triggered by inappropriate implant height, eccentric stresses via hybrid constructs, eccentric loading due to unconstrained devices and unaddressed Luschka joint degeneration. Such factors require careful selection of patients for surgery, necessitate proper pre-operative templating and call for appropriate technical solutions during surgery

Background:. Cervical spine injured patients often require prolonged ventilatory support due to intercostal paralysis and recurrent chest infections. This may necessitate tracheotomy. Concern exists around increased complications when anterior cervical spine surgery and tracheotomies are performed. Objective:. The primary aim of this study was to evaluate the effect of tracheostomy in anterior cervical surgery patients in term of complications. In addition, the aetiology of trauma and incidence of anterior surgery and ventilation in this patient group was assessed. Methods:. Patients undergoing anterior cervical surgery and requiring ventilation were identified from the unit's prospectively maintained database. These patients were further sub-divided into whether they had a tracheotomy or not. The aetiology of injury and incidence of complications were noted both from the database and a case note review. Results:. Of the 1829 admissions over an 8.5 year period, 444 underwent anterior cervical surgery. Of these 112 required ventilation, and 72 underwent tracheotomy. Motor vehicle accidents, followed by falls, were the most frequent cause of injury. There was a bimodal incidence of tracheostomy insertion; on the day of spine surgery and 6–8 days later. There was no difference in the general complication rate between the two groups. With regards to specific complications attributable to the surgical approach / tracheotomy, there was again no statistically significant difference. The timing of the tracheotomy equally had no effect on complication rate. Although the complications occurred mostly in the formal insertion group as opposed to percutaneous insertion technique, this was most likely due to selection bias. Conclusion:. Anterior cervical surgery and subsequent tracheostomy are safe despite the intuitive concerns. Timing does not affect the incidence of complications and there is no reason to delay the insertion of the tracheotomy. Ventilation in general is associated with increased complications rather the tracheotomy tube

Purpose. Patient expectations influence post-treatment outcomes, both surgical and non-surgical. Existing studies evaluate the technical aspects of interventions and functional outcomes but fail to take into account patient expectations. This retrospective analysis of prospectively collected multi-center data aims to explore the relationship between pre-operative expectations and post-operative outcomes and satisfaction in lumbar and cervical spine surgery. The authors hypothesized that expectations dramatically affect spine patient satisfaction independent of functional outcomes. Method. Patient data from lumbar and cervical spine patients collected prospectively using a patient health survey system was analyzed. The study included patients who underwent operative intervention (decompression with or without fusion) with at least a 3-month period of follow-up. Pre-operative expectations were measured using the MODEMS expectation survey. Post-operative satisfaction and fulfillment of expectations were measured using the MODEMS satisfaction survey. Post-operative functional outcomes were measured using the ODI and SF-36. Multi-variate ordinal logistic regression modeling was used to examine predictors of post-operative satisfaction. Multi-variate linear regression modeling was used to examine predictors of functional outcomes. Results. 402 patients were included in the study. Significant predictors of increased satisfaction include: higher fulfillment of expectations regarding work (p=0.003) and pain relief (p=0.008), greater post-operative SF-36 (p=0.04), and lower pre-operative expectations regarding ability to exercise (p=0.03). Lumbar spine patients were more satisfied than cervical-spine patients. Significant predictors of better post-operative function include: higher expectations regarding sleep (p<0.0002), fulfillment of expectations regarding work (p<0.0001), sleep (p=0.03), and daily activities (p=0.02). Cervical spine patients had better functional outcomes (p=0.006). Conclusion. This study showed that pre-operative expectations and their fulfillment influence post-operative satisfaction in lumbar and cervical spine patients. This underlines the importance of taking pre-operative expectations into account in order to obtain an informed choice based on patient preferences
