A systematic review and meta-analysis of randomized controlled trials on the effectiveness of high-intensity laser therapy in the management of neck pain.

The purpose of this systematic review was to evaluate the effects of high-intensity laser therapy (HILT) on pain, disability, and range of movement in patients with neck pain. Randomized controlled trials (RCTs) of HILT for neck pain disorders were searched across databases such as PubMed, Web of Science, Scopus, CINAHL, Science Direct, Cochrane Library, the PEDro database, and Google Scholar (updated January 7, 2024). The main outcome was pain intensity, with neck disability and cervical range of motion as secondary outcomes. Researchers reviewed article titles and abstracts from different databases using the Rayyan web app. Study quality was assessed using the Cochrane risk of bias tool, and evidence-based recommendations were developed using the GRADE approach. A meta-analysis was conducted to calculate the pooled effect in terms of mean differences (MD) for the outcomes of interest, along with a 95% confidence interval (95% CI). Twenty studies met the selection criteria and were potentially eligible for inclusion in the meta-analysis. At the end of the treatment, there was a statistically significant (p < 0.01) pooled MD of -14.1 mm for pain intensity (17 RCTs) with the VAS (95% CI:-18.4,-9.7), 3.9° (95% CI:1.9,6.7) for cervical extension (9 RCTs), and -8.3% (95% CI:-14.1,-4.1) for disability diminish (12 RCTs) with the neck disability index in favor of HILT. Only the results for pain intensity are in line with the minimal clinically important differences (MCID) reported in the literature. Overall, the evidence was deemed significant but with low certainty, attributed to observed heterogeneity and some risk of bias among the RCTs. HILT demonstrates effectiveness in reducing neck pain and disability while enhancing cervical extension when added to other physical therapy interventions, especially therapeutic exercise, based on a moderate level of evidence. This review highlights that the most favorable results are obtained when HILT is employed to address myofascial pain, cervical radiculopathy and chronic neck pain.PROSPERO registration number: CRD42023387394 (Registration date, 14/01/2023).

Comparison of the Outcomes of Anterior Cervical Discectomy and Fusion and Cervical Disc Replacement for Cervical Disc Disease.

OBJECTIVE: To compare the radiological outcome and development of heterotopic ossification (HO) following single-segment anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (CDR) for cervical disc herniation and evaluate their impact on surgical success. STUDY DESIGN: Descriptive comparative study. Place and Duration of the Study: Neurosurgery Department at Bozyaka Education and Research Hospital, Izmir, Turkiye, between January 2020 and June 2022. METHODOLOGY: Patients aged 18-70 years with radicular neck pain unresponsive to conventional medical treatment and an MRI-confirmed diagnosis were included. Patients with osteoporosis (OP) were excluded. Patients were randomised into two treatment groups (ACDF and CDR) and stratified by age and symptom severity. Radiographic assessments and HO classification according to McAfee were performed. RESULTS: Among the included patients, 56 underwent ACDF and 45 underwent CDR. The mean patient age was 48.29 ± 9.530 and 41.84 ± 7.239 years in the ACDF and CDR groups, respectively (p <0.001). The postoperative disc height increased in both groups. The T1 slope was significantly higher preoperatively and in the early postoperative period in the CDR group than in the ACDF group (p = 0.001). HO was graded as 1, 2, 3, and 4 in 28 (27.7%), 6 (5.9%), 7 (6.9%), and 4 (3%) patients, respectively. CONCLUSION: ACDF and CDR provided similar improvements in radiological measurements and pain relief. Although both procedures significantly enhanced the patient's quality of life and disability scores, HO was more prevalent following CDR during long-term follow-up.

Neurologic Approach to Radiculopathy, Back Pain, and Neck Pain.

Back pain and neck pain are common in clinical practice, but significant challenges and pitfalls exist in their diagnosis, treatment, and management. From the neurologic standpoint, cervical radiculopathy and lumbosacral radiculopathy are characterized by neck pain or back pain accompanied by sensory and motor symptoms in an arm or leg. The basic neurologic examination is vital, but testing like electromyography and MRI is often needed especially in cases that fail conservative management. Oral medications, injection-based therapies, physical therapy, and surgical evaluation all have a place in the comprehensive neurologic management of back and neck pain and associated radiculopathy.

Do key measurement parameters derived from specific cervical vertebral segments differ between lordotic and non-lordotic cervical spine alignments? A study of asymptomatic young adults.

BACKGROUND: Measurement parameters derived from specific cervical vertebral segments (e.g., C2 slope) can provide clinicians with important information on cervical sagittal balance and guide pre- and post-surgical decision-making processes. It is unclear however, what constitutes typical values for these types of measurements in an asymptomatic population of young adults, whether values change depending upon the classification of the cervical spine's global alignment, and if any non-lordotic cervical subtypes display values that are comparable to those reported for pre-surgery patients. METHODS: Neutral lateral cervical radiographs of 150 asymptomatic participants (18-30 years) were taken. Global cervical alignment was classified as lordotic or one of four non-lordotic subtypes using a multi-method subtyping protocol. Four key measurement parameters - the anterior translation of the head measure (ATHM), C0-C2 angle, C2 slope, and C7 slope - were derived from specific cervical segments. Independent samples t-tests were used to compare lordotic and non-lordotic groups. RESULTS: There was considerable variation in the four key measurement parameters amongst this asymptomatic population of young adults. Thirty-four percent of the sample were classified as lordotic and 66% were classified as non-lordotic. There was a significant difference (p ≤ 0.0125) between lordotic and non-lordotic groups for the C0-C2 angle, C2 slope and C7 slope. There was no difference between groups for the ATHM (p ≥ 0.0125). Within the non-lordotic group, the global-kyphotic (GK) subtype had the largest mean C2 slope, largest mean C0-C2 angle, and smallest mean C7 slope. CONCLUSIONS: Long term prospective investigations are required to determine whether possible biomarkers (alignment parameters/radiological measurements) for spinal degenerative changes can be identified so that early interventions can be put in place to try and reduce the impact of neck pain on society.

Heterotopic ossification, osteolysis and implant failure following cervical total disc replacement with the M6-C™ artificial disc.

INTRODUCTION: A recent study reported a 34% mid-term revision rate after M6-C™ cervical total disc replacement (CTDR) for wear-related osteolysis. Here, we aim to investigate the prevalence, risk factors, and radiographic characteristics of periprosthetic bony changes and implant failure of the M6-C™ artificial disc. METHODS: We retrospectively analysed radiographic (conventional X-ray, CT scan) and clinical outcomes (EQ-5D-5L, Neck Disability Index (NDI), and Visual Analog Scale (VAS) for neck and arm pain) data collected during routine follow-up of patients who underwent CTDR with the M6-C™ between 2011 and 2015. RESULTS: In total, 85 patients underwent CTDR with the M6-C™. Follow-up data were available for 43 patients (54% female, mean age 44 years) with 50 implants and a mean follow-up of 8.1 years (6.5-11 years). Implant failure with the presence of severe osteolysis was identified in 5 (12%) patients who were all male (p = 0.016) and implanted at the C5/6 level (p = 0.11). All failed implants required revision surgery. The overall prevalence of osteolysis was 44% (22/50 implants) and 34% (17/50 implants) for significant heterotopic ossification. Patients with high-grade osteolysis showed higher VAS arm pain (p = 0.05) and lower EQ-5D-VAS health VAS (p = 0.03). CONCLUSION: We report a lower reoperation rate for failed M6-C™ implants than previously published, but confirmed that osteolysis and heterotopic ossification are common following CTDR with the M6-C™ and may be asymptomatic. Therefore, we strongly recommend ongoing clinical and radiographic monitoring after CTDR with the M6-C™, particularly for male patients implanted at the C5/6 level.

Comparison of Selective Nerve Root Pulsed Radiofrequency Vs Paramedian Interlaminar Epidural Steroid Injection for the Treatment of Painful Cervical Radiculopathy.

BACKGROUND: Although there are studies evaluating ultrasound-guided selective nerve root pulsed radiofrequency (ULSD-SNRPRF) and fluoroscopy-guided paramedian cervical interlaminar epidural steroid injection (FL-CIESI) for the treatment of chronic cervical radicular pain, no study has compared the efficacy of these 2 methods. OBJECTIVES: This study aimed to compare the efficacy of these 2 methods, their superiority to each other, and the incidence of adverse events. STUDY DESIGN: A prospective, randomized controlled trial. SETTING: Outpatient department of a single-center pain clinic. METHODS: Sixty patients who did not respond to conservative treatments for lower cervical radicular pain were randomly divided into 2 groups. One group underwent ULSD-SNRPRF (Group U), and the other underwent paramedian FL-CIESI (Group F). Patients were evaluated pretreatment, and 3 and 6 months posttreatment. The Numeric Rating Scale (NRS-11) was used to assess clinical improvement, The Neck Disability Index (NDI) to assess improvement in functional disability, and the Self-Leeds Assessment of Neuropathic Symptoms and Signs Pain Score (S-LANSS) to assess the treatment's effect on neuropathic pain. Clinically significant pain relief was defined as a 50% or more pain reduction in the NRS-11. The posttreatment reduction in medication consumption was assessed using the Medication Quantification Scale Version III (MQS III). We also evaluated whether there was a difference in treatment-related characteristics, such as procedure time and adverse events. RESULTS: The procedure time was significantly longer in Group U. Blood aspiration was observed in 2 patients in Group U and vascular spread in one patient in Group F, with no significant difference. At 3 and 6 months posttreatment, NRS-11 and NDI scores showed a significant decrease compared to the pretreatment scores in both groups; there was no difference between the groups. Both treatments effectively improved neuropathic pain, with no significant difference between the S-LANSS scores. There was no difference in the reduction of medication consumption between the groups. LIMITATIONS: There was no sham or control group, and the follow-up period was limited to 6 months. CONCLUSIONS: Pain relief, functional improvement, and safety were similar between groups. ULSD-SNRPRF and paramedian FL-CIESI are 2 different effective techniques for chronic cervical radicular pain. The choice of method should depend on various factors, such as patient preference, operator experience, and availability of resources. An advantage of ULSD over fluoroscopy is that patients and physicians are not exposed to radiation.

What predicts the best 24-month outcomes following surgery for cervical spondylotic myelopathy? A QOD prospective registry study.

OBJECTIVE: The aim of this study was to identify predictors of the best 24-month improvements in patients undergoing surgery for cervical spondylotic myelopathy (CSM). For this purpose, the authors leveraged a large prospective cohort of surgically treated patients with CSM to identify factors predicting the best outcomes for disability, quality of life, and functional status following surgery. METHODS: This was a retrospective analysis of prospectively collected data. The Quality Outcomes Database (QOD) CSM dataset (1141 patients) at 14 top enrolling sites was used. Baseline and surgical characteristics were compared for those reporting the top and bottom 20th percentile 24-month Neck Disability Index (NDI), EuroQol-5D (EQ-5D), and modified Japanese Orthopaedic Association (mJOA) change scores. A multivariable logistic model was constructed and included candidate variables reaching p ≤ 0.20 on univariate analyses. Least important variables were removed in a stepwise manner to determine the significant predictors of the best outcomes (top 20th percentile) for 24-month NDI, EQ-5D, and mJOA change. RESULTS: A total of 948 (83.1%) patients with 24-month follow-up were included in this study. For NDI, 204 (17.9%) had the best NDI outcome and 200 (17.5%) had the worst NDI outcome. Factors predicting the best NDI outcomes included symptom duration less than 12 months (OR 1.5, 95% CI 1.1-1.9; p = 0.01); procedure other than posterior fusion (OR 1.5, 95% CI 1.03-2.1; p = 0.03); higher preoperative visual analog scale neck pain score (OR 1.2, 95% CI 1.1-1.3; p < 0.001); and higher baseline NDI (OR 1.06, 95% CI 1.05-1.07; p < 0.001). For EQ-5D, 163 (14.3%) had the best EQ-5D outcome and 169 (14.8%) had the worst EQ-5D outcome. Factors predicting the best EQ-5D outcomes included arm pain-only complaints (compared to neck pain) (OR 1.9, 95% CI 1.3-2.9; p = 0.002) and lower baseline EQ-5D (OR 167.7 per unit lower, 95% CI 85.0-339.4; p < 0.001). For mJOA, 222 (19.5%) had the best mJOA outcome and 238 (20.9%) had the worst mJOA outcome. Factors predicting the best mJOA outcomes included lower BMI (OR 1.03 per unit lower, 95% CI 1.004-1.05; p = 0.02; cutoff value of ≤ 29.5 kg/m2); arm pain-only complaints (compared to neck pain) (OR 1.7, 95% CI 1.1-2.5; p = 0.02); and lower baseline mJOA (OR 1.6 per unit lower, 95% CI 1.5-1.7; p < 0.001). CONCLUSIONS: Compared to the worst outcomes for EQ-5D, the best outcomes were associated with patients with arm pain-only complaints. For mJOA, lower BMI and arm pain-only complaints portended the best outcomes. For NDI, those with the best outcomes had shorter symptom durations, higher preoperative neck pain scores, and less often underwent posterior spinal fusions. Given the positive impact of shorter symptom duration on outcomes, these data suggest that early surgery may be beneficial for patients with CSM.

Effect of Baseline Veterans RAND-12 Mental Composite Score on Postoperative Patient-Reported Outcome Measures for Cervical Disk Replacement.

STUDY DESIGN: Retrospective review. OBJECTIVE: To examine the effect of baseline Veterans RAND-12 (VR-12) Mental Composite Score (MCS) on clinical outcomes in patients undergoing cervical disk replacement (CDR) for herniated disk. BACKGROUND: Few studies in spine surgery have evaluated the impact of preoperative VR-12 MCS on postoperative outcomes in patients undergoing CDR. METHODS: Patients undergoing CDR for herniated disk were separated into 2 cohorts based on the VR-12 MCS standardized mean: VR-12 MCS<50 (worse mental health) and VR-12 MCS≥50 (better mental health). Patient-reported outcome measures of VR-12 MCS, VR-12 Physical Composite Score, Short Form-12 (SF-12) MCS, SF-12 Physical Composite Score, Patient-Reported Outcomes Measurement Information System Physical Function, Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Neck Pain, VAS Arm Pain, and Neck Disability Index were collected at preoperative and up to 2-year postoperative time points. RESULTS: In all, 109 patients were identified, with 50 patients in the worse mental health cohort. The worse mental health cohort reported inferior patient-reported outcome measures in all domains at preoperative, 6-week postoperative, and final postoperative time points. For 6-week postoperative improvement, the worse mental health cohort reported greater improvement for VR-12 MCS, SF-12 MCS, and PHQ-9. For final postoperative improvement, the worse mental health cohort reported greater improvement in VR-12 MCS and SF-12 MCS. Minimum clinically important difference achievement rates were higher in the worse mental health cohort for VR-12 MCS, SF-12 MCS, and PHQ-9. CONCLUSION: Patients undergoing cervical disk replacement for herniated disk with worse baseline mental health reported inferior clinical outcomes in mental health, physical function, pain, and disability outcomes throughout the postoperative period. Patients with worse baseline mental health demonstrated greater clinically meaningful improvement in mental health. In cervical disk replacement patients, those with worse baseline mental health may report inferior postoperative clinical outcomes but experience greater rates of tangible improvement in mental health.

Degenerative Cervical Myelopathy: A Concept Review and Clinical Approach.

STUDY DESIGN: Narrative review. OBJECTIVE: To provide an overview of the evaluation and diagnosis of degenerative cervical myelopathy (DCM). SUMMARY OF BACKGROUND DATA: DCM describes several etiologies of degenerative, nontraumatic spinal cord impairment. Early diagnosis and intervention can decrease neurological decline. METHODS: An extensive literature review was conducted. RESULTS: The incidence and prevalence of DCM are increasing worldwide. Asymptomatic spinal cord compression can progress to cervical myelopathy. Static and dynamic factors contribute to spinal cord compression. Patients frequently present with decreased manual dexterity, gait instability, and neck pain. On physical exam, patients frequently present with upper motor neuron signs, a Lhermitte sign, a failed Romberg test, global proprioceptive dysfunction, and decreased pain sensation. Anatomic variation may complicate physical exam interpretation. The modified Japanese Orthopaedic Association Scale and Nurick Classification, based on functional impairment, provide diagnostic utility. Magnetic Resonance Imaging imaging is useful in narrowing the differential diagnosis, evaluating the severity of neurological impairment, and predicting disease progression. CONCLUSIONS: Understanding the pathophysiology of DCM and the diagnostic utility of the signs and symptoms of DCM is critical. The decision for anterior cervical discectomy and fusion (ACDF), laminoplasty, or combined ACDF and posterior cervical fusion is individualized for each patient.

Chronic neck pain in a child: a case of osteoblastoma of the C5 cervical vertebra.

Osteoblastoma is a primary bone-forming tumour that usually occurs in the second decade with an affinity to the posterior elements when found in the spine. Its occurrence in the early first decade is uncommon and often causes a diagnostic dilemma. It usually has a late presentation and the symptoms may be non-specific which may lead the clinician to overlook this particular entity. We present a case of osteoblastoma of the posterior elements of the C5 vertebra in a pre-adolescent child who was diagnosed and successfully managed with surgical resection in a timely fashion that led to favourable recovery postoperatively.

C-arm CT guided percutaneous vertebroplasty for pain release in cancer patient with cervical 1 vertebral metastases: A case report.

OBJECTIVE: To evaluate the efficacy and treatment outcome of C-arm CT percutaneous vertebroplasty in the treatment of cervical 1 (C1) vertebral metastases. METHODS: This report recruited a male patient diagnosed with hepatocellular carcinoma and C1 vertebral metastases, who had suffered from severe neck pain symptoms and the analgesic showed little soothing effect. Under the guidance of C-arm CT, an 18G coaxial needle was used to puncture the left lateral mass of C1 vertebral metastases from lateral space between thyroid cartilage and the left carotid sheath, with 2 ml bone cement injected. RESULTS: Postoperative C-arm CT three-dimensional reconstruction scan showed that the bone cement was well filled and distributed in the left lateral mass of C1 vertebral body, and no leakage of bone cement was observed. The neck pain of the patients was significantly relieved one week after the operation. CONCLUSION: Under the guidance of C-arm CT, cement augmentation using percutaneous vertebroplasty in an anterior cervical direction could serve as a safe and effective pain relief approach for patients with C1 vertebral metastases.

Is neck pain treatable with surgery?

INTRODUCTION: Neck pain is one of the most common complaints in clinical practice and can be caused by a wide variety of conditions. While cervical spine surgery is a well-accepted option for radicular pain and myelopathy, surgery for isolated neck pain is controversial. The identification of the source of pain is challenging and subtle, and misdiagnosis can lead to inappropriate treatment. MATERIALS AND METHODS AND RESULTS: We conducted a thorough literature review to discuss and compare different causes of neck pain. We then supplemented the literature with our senior author's expert analysis of treating cervical spine pathology. CONCLUSIONS: This study provides an in-depth discussion of neck pain and its various presentations, as well as providing insight into treatment strategies and diagnostic pearls that may prevent mistreatment of cervical spine pathology.

Cadaveric study of ergonomics and performance using a robotic exoscope with a head-mounted display in spine surgery.

The conventional microscope has the disadvantage of a potentially unergonomic posture for the surgeon, which can affect performance. Monitor-based exoscopes could provide a more ergonomic posture, as already shown in pre-clinical studies. The aim of this study was to test the usability and comfort of a novel head-mounted display (HMD)-based exoscope on spinal surgical approaches in a simulated OR setting. A total of 21 neurosurgeons naïve to the device were participated in this prospective trial. After a standardized training session with the device, participants were asked to perform a single-level thoracolumbar decompression surgery on human cadavers using the exoscope. Subsequently, all participants completed a comfort and safety questionnaire. For the objective evaluation of the performance, all interventions were videotaped and analyzed. Twelve men and nine women with a mean age of 34 (range: 24-57) were participating in the study. Average time for decompression was 15 min (IqR 9.6; 24.2); three participants (14%) terminated the procedure prematurely. In these dropouts, a significantly higher incidence of back/neck pain (p = 0.002 for back, p = 0.046 for neck pain) as well as an increased frequency of HMD readjustments (p = 0.045) and decreased depth perception (p = 0.03) were documented. Overall, the surgeons' satisfaction with the exoscope was 84% (IqR 75; 100). Using a standardized, pre-interventional training, it is possible for exoscope-naïve surgeons to perform sufficient spinal decompression using the HMD-based exoscope with a high satisfaction. However, inaccurate HMD setup prior to the start of the procedure may lead to discomfort and unsatisfactory results.

Effect of long-term cervical extensor exercise program on functional disability, pain intensity, range of motion, cervical muscle mass, and cervical curvature in young adult population with chronic non-specific neck pain: a randomized controlled trial.

BACKGROUND: The prevalence of chronic non-specific neck pain (CNNP) is on the rise among the young adult population. We herein aimed to compare the effects of long-term specific cervical extensor training and stretching exercises on improving this chronic disorder in young adults. METHODS: In this prospective, randomized, controlled study, 70 participants aged 18-35 years with CNNP and cervical lordosis loss were included. The participants were assigned to undergo either specific cervical extensor training (observation group) or perform usual stretching exercises (control group). The exercise duration was set at 12 months, with 9 months at the clinic and 3 months at home. The outcome assessments included changes in the neck disability index, visual analog scale from baseline, cervical range of motion (CROM), cross-sectional areas (CSAs) of cervical extensors, and cervical curvature from baseline. The outcome measures were compared between groups at 3, 6, and 12 months of follow-up. RESULTS: All 70 participants underwent randomization, and no significant differences in demographics and baseline data were found between the two groups. The observation group showed a greater improvement in neck disability index and visual analog scale scores at the 12-month follow-up than the control group. Additionally, a more substantial increase in CROM and CSAs of cervical extensors was observed in the observation group at the 6-month and 12-month follow-ups (P < 0.05). Although more participants in the observation group achieved cervical lordosis at the 12-month follow-up, the difference was marginally nonsignificant (9% in the control group vs. 28% in the observation group, P = 0.075). CONCLUSIONS: In young adults with CNNP, long-term specific cervical extensor training was associated with a more significant clinically meaningful improvement in disability, pain, and CROM than stretching exercises. The increased CSAs of cervical extensors may potentially contribute to the restoration of cervical lordosis.

Eagle Syndrome: An Unusual Cause of Axial Neck Pain: A Case Report.

CASE: A 42-year-old woman presented with left-sided axial neck pain with radiation behind left ear of 3 months unresponsive to conservative treatment. As clinical examination revealed tenderness anterior to the mastoid process, she was referred to an otolaryngologist. Computed tomography showed an elongated left styloid process. Diagnostic local anesthetic infiltration provided complete pain relief confirming the diagnosis of Eagle syndrome (ES) after which a transoral excision of the left styloid process was performed. She was asymptomatic till the final follow-up of 15 months. CONCLUSION: ES should be considered in differential diagnosis of axial neck pain radiating to ear, and excision of the styloid process in resistant cases provides complete pain relief.

Distinguishing sterile inflammation from graft infection.

We describe the case of a 68-year-old man who underwent ascending aortic replacement and thoracic endovascular aortic repair. Four years later, the patient developed neck pain on the right side and chest computed tomography showed expansion of fluid in the mediastinum which had extended to the neck. Echocardiography revealed advanced severity of aortic regurgitation and decreased ejection fraction. Given the progression of aortic regurgitation, decreased cardiac function, and rapidly expanding fluid accumulation causing neck pain, reoperation was indicated. All microbiological test including polymerase chain reaction were negative indicating absence of any infection. The patient is being followed-up without antibiotics and CT has not shown peri-graft fluid 2 years postoperatively. Since infection cannot be excluded completely, it is important to assess the condition with selective medium, extended culture periods, genetic testing, and consultations with microbiology laboratories when normal culture tests for general bacteria, and fungi are negative which can help avoid drug-resistant bacteria count, elevated medical costs, and drug side effects due to the improper use of antibiotics through proper diagnosis.

Use of Soft Cervical Collar Improves Surgeon Ergonomics During Simulated Otologic Surgery.

OBJECTIVE: To determine whether surgeon use of a soft cervical collar during endoscopic and microscopic otologic surgery is feasible and impacts surgeon ergonomics as measured by inertial sensors. STUDY DESIGN: Prospective crossover trial. SETTING: US-based otolaryngology training program. PATIENTS: Otolaryngology residents and fellows. INTERVENTIONS: Therapeutic-use of a soft cervical collar during simulated otologic surgery. MAIN OUTCOME MEASURES: Time spent in high-risk angles of neck and back flexion and extension; average angle of neck flexion, extension, rotation, and lateral bending; validated assessment of neck pain; average daily phone use. RESULTS: Fifteen subjects met criteria for inclusion. Ten of 15 (67%) were male. Seven of 15 (47%) were postgraduate year 1-2. Seven of 15 (47%) reported a history of neck pain. None reported prior spinal steroid injections or surgery. Across all subjects, use of the soft cervical collar significantly reduced time spent in high-risk angles of neck flexion/extension during both endoscopic (56% vs. 35%, p < 0.05) and microscopic (60% vs. 32%, p < 0.05) otologic surgery. There was no effect on back flexion or extension. There was no difference in time spent in high-risk neck or back angles between endoscopic and microscopic surgery. Average angles of neck or back flexion, extension, lateral bending, and rotation were not significantly different for subgroups with more operative experience, increased phone use, perception of good posture, or history of neck pain. CONCLUSIONS: Use of a soft cervical collar during simulated otologic surgery significantly reduced time spent in high-risk neck positions. These data support feasibility of soft collar use during otologic surgery and hold promise for reduction in the high rates of neck pain reported by neurotologists. PROFESSIONAL PRACTICE GAP AND EDUCATIONAL NEED: Improving surgeon ergonomics for otologic surgery. LEARNING OBJECTIVE: To identify a therapeutic intervention to mitigate neck pain in surgeons caused by assumption of high-risk cervical neck flexion and extension. DESIRED RESULT: To demonstrate that use of a readily available soft cervical collar reduces risk of neck pain in otologic surgeons. LEVEL OF EVIDENCE: II. INDICATE IRB OR IACUC: Exempt.

Does the number of social factors affect long-term patient-reported outcomes and satisfaction in those with cervical myelopathy? A QOD study.

OBJECTIVE: It is not clear whether there is an additive effect of social factors in keeping patients with cervical spondylotic myelopathy (CSM) from achieving both a minimum clinically important difference (MCID) in outcomes and satisfaction after surgery. The aim of this study was to explore the effect of multiple social factors on postoperative outcomes and satisfaction. METHODS: This was a multiinstitutional, retrospective study of the prospective Quality Outcomes Database (QOD) CSM cohort, which included patients aged 18 years or older who were diagnosed with primary CSM and underwent operative management. Social factors included race (White vs non-White), education (high school or below vs above), employment (employed vs not), and insurance (private vs nonprivate). Patients were considered to have improved from surgery if the following criteria were met: 1) they reported a score of 1 or 2 on the North American Spine Society index, and 2) they met the MCID in patient-reported outcomes (i.e., visual analog scale [VAS] neck and arm pain, Neck Disability Index [NDI], and EuroQol-5D [EQ-5D]). RESULTS: Of the 1141 patients included in the study, 205 (18.0%) had 0, 347 (30.4%) had 1, 334 (29.3%) had 2, and 255 (22.3%) had 3 social factors. The 24-month follow-up rate was > 80% for all patient-reported outcomes. After adjusting for all relevant covariates (p < 0.02), patients with 1 or more social factors were less likely to improve from surgery in all measured outcomes including VAS neck pain (OR 0.90, 95% CI 0.83-0.99) and arm pain (OR 0.88, 95% CI 0.80-0.96); NDI (OR 0.90, 95% CI 0.83-0.98); and EQ-5D (OR 0.90, 95% CI 0.83-0.97) (all p < 0.05) compared to those without any social factors. Patients with 2 social factors (outcomes: neck pain OR 0.86, arm pain OR 0.81, NDI OR 0.84, EQ-5D OR 0.81; all p < 0.05) or 3 social factors (outcomes: neck pain OR 0.84, arm pain OR 0.84, NDI OR 0.84, EQ-5D OR 0.84; all p < 0.05) were more likely to fare worse in all outcomes compared to those with only 1 social factor. CONCLUSIONS: Compared to those without any social factors, patients who had at least 1 social factor were less likely to achieve MCID and feel satisfied after surgery. The effect of social factors is additive in that patients with a higher number of factors are less likely to improve compared to those with only 1 social factor.
