BACKGROUND: Degenerative cervical myelopathy (DCM) is a progressive chronic spinal cord injury estimated to affect 1 in 50 adults. Without standardised guidance, clinical research studies have selected outcomes at their discretion, often underrepresenting the disease and limiting comparability between studies. Utilising a standard minimum data set formed via multi-stakeholder consensus can address these issues. This combines processes to define a core outcome set (COS)-a list of key outcomes-and core data elements (CDEs), a list of key sampling characteristics required to interpret the outcomes. Further \"how\" these outcomes should be measured and/or reported is then defined in a core measurement set (CMS). This can include a recommendation of a standardised time point at which outcome data should be reported. This study defines a COS, CDE, and CMS for DCM research.
RESULTS: A minimum data set was developed using a series of modified Delphi processes. Phase 1 involved the setup of an international DCM stakeholder group. Phase 2 involved the development of a longlist of outcomes, data elements, and formation into domains. Phase 3 prioritised the outcomes and CDEs using a two-stage Delphi process. Phase 4 determined the final DCM minimal data set using a consensus meeting. Using the COS, Phase 5 finalised definitions of the measurement construct for each outcome. In Phase 6, a systematic review of the literature was performed, to scope and define the psychometric properties of measurement tools. Phase 7 used a modified Delphi process to inform the short-listing of candidate measurement tools. The final measurement set was then formed through a consensus meeting (Phase 8). To support implementation, the data set was then integrated into template clinical research forms (CRFs) for use in future clinical trials (Phase 9). In total, 28 outcomes and 6 domains (Pain, Neurological Function, Life Impact, Radiology, Economic Impact, and Adverse Events) were entered into the final COS. Thirty two outcomes and 4 domains (Individual, Disease, Investigation, and Intervention) were entered into the final CDE. Finally, 4 outcome instruments (mJOA, NDI, SF-36v2, and SAVES2) were identified for the CMS, with a recommendation for trials evaluating outcomes after surgery, to include baseline measurement and at 6 months from surgery.
CONCLUSIONS: The AO Spine RECODE-DCM has produced a minimum data set for use in DCM clinical trials today. These are available at https://myelopathy.org/minimum-dataset/. While it is anticipated the CDE and COS have strong and durable relevance, it is acknowledged that new measurement tools, alongside an increasing transition to study patients not undergoing surgery, may necessitate updates and adaptation, particularly with respect to the CMS.

Cervical artificial disc replacement preserves the range of motion after the decompression, and this technology has achieved good clinical results. The indications, surgical procedures, and perioperative management of cervical disc arthroplasty are different from traditional anterior cervical decompression and fusion. The Health Management and Enhanced Recovery of Cervical Spine Disorders Committee, Chinese Research Hospital Association has established an expert group to draw up this expert consensus through literature analysis and professional discussions. The purpose of this consensus is to standardize the surgical indications and patient selection of cervical artificial disc replacement, to guide surgical procedures and perioperative management, and to improve the clinical outcomes of cervical artificial disc replacement.

BACKGROUND: There are concerns that airway management in patients with suspected or confirmed cervical spine injury may exacerbate an existing neurological deficit, cause a new spinal cord injury or be hazardous due to precautions to avoid neurological injury. However, there are no evidence-based guidelines for practicing clinicians to support safe and effective airway management in this setting.
METHODS: An expert multidisciplinary, multi-society working party conducted a systematic review of contemporary literature (January 2012-June 2022), followed by a three-round Delphi process to produce guidelines to improve airway management for patients with suspected or confirmed cervical spine injury.
RESULTS: We included 67 articles in the systematic review, and successfully agreed 23 recommendations. Evidence supporting recommendations was generally modest, and only one moderate and two strong recommendations were made. Overall, recommendations highlight key principles and techniques for pre-oxygenation and facemask ventilation; supraglottic airway device use; tracheal intubation; adjuncts during tracheal intubation; cricoid force and external laryngeal manipulation; emergency front-of-neck airway access; awake tracheal intubation; and cervical spine immobilisation. We also signpost to recommendations on pre-hospital care, military settings and principles in human factors.
CONCLUSIONS: It is hoped that the pragmatic approach to airway management made within these guidelines will improve the safety and efficacy of airway management in adult patients with suspected or confirmed cervical spine injury.

The \"Clinical Guidelines for Diagnosis and Treatment of Cervical Spondylotic Myelopathy with the Integrated Traditional Chinese and Western Medicine\" were formulated by the Orthopedic and Traumatology Professional Committee of the Chinese Association of Integrative Medicine in accordance with the principles of evidence-based medicine and expert consensus, and provide clinicians with academic guidance on clinical diagnosis and treatment of CSM. The main content includes diagnostic points, disease grading assessment, TCM syndrome differentiation, surgical indications and timing, integrated traditional Chinese and Western medicine treatment, and postoperative rehabilitation. This guideline proposes for the first time that the treatment of CSM should follow the principle of grading, clarify the timing and methods of surgical treatment, establish common TCM syndrome differentiation and classification, attach importance to postoperative integrated rehabilitation of Chinese and Western medicine, and strengthen daily follow-up management. It hopes to promote the standardization, effectiveness, and safety of clinical treatment of CSM.

This review aims to evaluate current practices regarding spine immobilization in pediatric trauma patients to evaluate their efficacy, reliability, and impact on clinical outcomes to guide future research and improved evidence-based practice guidelines.
PubMed, ProQuest, Embase, Google Scholar, and Cochrane were queried for studies pertaining to spinal immobilization practices in pediatric trauma patients. Articles were separated into studies that explored both the efficacy and clinical outcomes of spine immobilization. Outcomes evaluated included frequency of spinal imaging, self-reported pain level, emergency department length of stay (ED-LOS), and ED disposition.
Six articles were included, with two studies examining clinical outcomes and 4 studies evaluating the efficacy and reliability of immobilization techniques. Immobilized children were significantly more likely to undergo cervical spine imaging (OR 8.2, p < 0.001), be admitted to the floor (OR 4.0, p < 0.001), be taken to the ICU or OR (OR 5.3, p < 0.05) and reported a higher median pain score. Older children were significantly more likely to be immobilized. No immobilization techniques consistently achieved neutral positioning, and patients most often presented in a flexed position. Lapses in immobilization occurred in 71.4% of patients.
Immobilized pediatric patients underwent more cervical radiographs, and had higher hospital and ICU admission rates, and higher mean pain scores than those without immobilization. Immobilization was inconsistent across age groups and often resulted in lapses and improper alignment. Further research is needed to identify the most appropriate immobilization techniques for pediatric patients and when to use them.

Survey of cases.
To evaluate the opinion of experts in the diagnostic process of clinically relevant Spinal Post-traumatic Deformity (SPTD).
SPTD is a potential complication of spine trauma that can cause decreased function and quality of life impairment. The question of when SPTD becomes clinically relevant is yet to be resolved.
The survey of 7 cases was sent to 31 experts. The case presentation was medical history, diagnostic assessment, evaluation of diagnostic assessment, diagnosis, and treatment options. Means, ranges, percentages of participants, and descriptive statistics were calculated.
Seventeen spinal surgeons reviewed the presented cases. The items\' fracture type and complaints were rated by the participants as more important, but no agreement existed on the items of medical history. In patients with possible SPTD in the cervical spine (C) area, participants requested a conventional radiograph (CR) (76%-83%), a flexion/extension CR (61%-71%), a computed tomography (CT)-scan (76%-89%), and a magnetic resonance (MR)-scan (89%-94%). In thoracolumbar spine (ThL) cases, full spine CR (89%-100%), CT scan (72%-94%), and MR scan (65%-94%) were requested most often. There was a consensus on 5 out of 7 cases with clinically relevant SPTD (82%-100%). When consensus existed on the diagnosis of SPTD, there was a consensus on the case being compensated or decompensated and being symptomatic or asymptomatic.
There was strong agreement in 5 out of 7 cases on the presence of the diagnosis of clinically relevant SPTD. Among spine experts, there is a strong consensus to use CT scan and MR scan, a cervical CR for C-cases, and a full spine CR for ThL-cases. The lack of agreement on items of the medical history suggests that a Delphi study can help us reach a consensus on the essential items of clinically relevant SPTD.
Level V.

The American College of Radiology has published appropriateness criteria to help guide when to use MRI. Many health insurance carriers use proprietary clinical guidelines for prior authorization of imaging studies. The purpose of this study was to compare the specific criteria in those guidelines, for neck pain both with and without radicular symptoms. An online search was conducted to identify the guidelines for authorization of cervical spine MRI used by the largest commercial insurance carriers in the United States by market share. Guidelines were analyzed for neck pain with and without radiculopathy. Cervical trauma, myelopathy, infection, neoplasm, multiple sclerosis, and postprocedural care were excluded. The remaining criteria were broken down into categories including clinical symptoms, conservative therapy, other required radiologic studies, and clinical re-evaluation. Individual criteria within each of the categories were compared. After evaluation of the top 56 insurance companies in the United States, 30 companies using four main utilization management companies remained for analysis. After direct comparison of publicly available guidelines documents, notable discrepancies existed between the four companies in all subcategories analyzed. In addition, varying amounts of evidence-based literature was identified to support criteria requirements for prior authorization. This study demonstrates that the guidelines used by private health insurance companies for cervical MRI authorization in the setting of neck pain with and without cervical radiculopathy are inconsistent and use objective measures that have not been validated in the literature. We think this warrants additional scrutiny and investigation.

OBJECTIVE: Physical examination and computed tomography (CT) are useful to rule out cervical spine injury (CSI). Computed tomography scans increase lifetime cancer risk in children from radiation exposure. Most CSI in children occur between the occiput and C4. We developed a cervical spine (C-spine) clearance guideline to reduce unnecessary CTs and radiation exposure in pediatric trauma patients.
METHODS: A pediatric C-spine clearance guideline was implemented in September 2018 at our Level 2 Pediatric Trauma Center. Guidance included CT of C1 to C4 to scan only high-yield regions versus the entire C-spine and decrease radiation dose. A retrospective cohort study was conducted comparing preguideline and postguideline of all pediatric trauma patients younger than 8 years screened for CSI from July 2017 to December 2020. Primary endpoints included the following: number of full C-spine and C1 to C4 CT scans and radiation dose. Secondary endpoints were CSI rate and missed CSI. Results were compared using χ 2 and Wilcoxon rank-sum test with P < 0.05 significant.
RESULTS: The review identified 726 patients: 273 preguideline and 453 postguideline. A similar rate of total C-spine CTs were done in both groups (23.1% vs 23.4%, P = 0.92). Full C-spine CTs were more common preguideline (22.7% vs 11.9%, P < 0.001), whereas C1 to C4 CT scans were more common post-guideline (11.5% vs 0.4%, P < 0.001). Magnetic resonance imaging utilization and CSIs identified were similar in both groups. The average radiation dose was lower postguideline (114 vs 265 mGy·cm -1 ; P < 0.001). There were no missed CSI.
CONCLUSIONS: A pediatric C-spine clearance guideline led to increasing CT of C1 to C4 over full C-spine imaging, reducing the radiation dose in children.
METHODS: Level IV, therapeutic.

Cervical spine disorders in children are relatively uncommon; therefore, paradigms for surgical and nonsurgical clinical management are not well established. The purpose of this study was to bring together an international, multidisciplinary group of pediatric cervical spine experts to build consensus via a modified Delphi approach regarding the clinical management of children with cervical spine disorders and those undergoing cervical spine stabilization surgery.
A modified Delphi method was used to identify consensus statements for the management of children with cervical spine disorders requiring stabilization. A survey of current practices, supplemented by a literature review, was electronically distributed to 17 neurosurgeons and orthopedic surgeons experienced with the clinical management of pediatric cervical spine disorders. Subsequently, 52 summary statements were formulated and distributed to the group. Statements that reached near consensus or that were of particular interest were then discussed during an in-person meeting to attain further consensus. Consensus was defined as ≥ 80% agreement on a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree).
Forty-five consensus-driven statements were identified, with all participants willing to incorporate them into their practice. For children with cervical spine disorders and/or stabilization, consensus statements were divided into the following categories: A) preoperative planning (12 statements); B) radiographic thresholds of instability (4); C) intraoperative/perioperative management (15); D) postoperative care (11); and E) nonoperative management (3). Several important statements reaching consensus included the following recommendations: 1) to obtain pre-positioning baseline signals with intraoperative neuromonitoring; 2) to use rigid instrumentation when technically feasible; 3) to provide postoperative external immobilization for 6-12 weeks with a rigid cervical collar rather than halo vest immobilization; and 4) to continue clinical postoperative follow-up at least until anatomical cervical spine maturity was reached. In addition, preoperative radiographic thresholds for instability that reached consensus included the following: 1) translational motion ≥ 5 mm at C1-2 (excluding patients with Down syndrome) or ≥ 4 mm in the subaxial spine; 2) dynamic angulation in the subaxial spine ≥ 10°; and 3) abnormal motion and T2 signal change on MRI seen at the same level.
In this study, the authors have demonstrated that a multidisciplinary, international group of pediatric cervical spine experts was able to reach consensus on 45 statements regarding the management of pediatric cervical spine disorders and stabilization. Further study is required to determine if implementation of these practices can lead to reduced complications and improved outcomes for children.

Cervical spondylotic myelopathy (CSM) is the most serious subtype, which is characterized by severe clinical symptoms, a high disability rate, and poor prognosis. Traditional Chinese medicine and Western medicine have their own advantages in the diagnosis and treatment of CSM at different stages. In order to further standardize the clinical diagnosis and treatment of CSM and improve the clinical efficacy, based on previous experience and evidence-based medicine, after repeated discussions by the national expert group, the expert consensus on the diagnosis and treatment of integrated traditional Chinese and Western medicine was compiled. This consensus comprehensively introduces the definition, etiology, pathogenesis, diagnosis treatment principles, integrated traditional Chinese and Western medicine treatment, postoperative rehabilitation and nursing care of cervical spondylotic myelopathy, so as to provide reference for clinicians.
