Purpose The neck disability index (NDI) as a 10-item patient reported outcome (PRO) measure is the most commonly used whiplash associated disorders (WAD) assessment tool. However, statistical rigor and factor structure are not definitive. To date, confirmatory factor analysis (CFA) has not examined whether the factor structure generalizes across different groups (e.g., WAD versus non-WAD). This study aimed to determine the psychometric properties of the NDI in these population groups. ⋯ The NDI remains a valid PRO in WAD populations that provides acceptable measurement of neck status that is appropriate for basic functional assessment across genders. However, it is recommended that both clinicians and researchers initiate the transition toward more rigorous and less ambiguous PRO measurement tools for WAD patients and research. This future graduated movement toward other PROs should consider both regional PROs and computerized decision support systems, initially measured concurrently with the NDI to establish ways to convert existing scored data prior to their singular use.

The purpose of this study was to evaluate the 1-year outcome after anterior transarticular atlantoaxial fixation and odontoid fusion (TAFOF) for type II odontoid fractures and atlanto-odontoid osteoarthritis (AO) in elderly patients. ⋯ Anterior TAFOF leads to promising 1-year results with low in-hospital mortality and a high fusion rate in geriatric patients with type II odontoid fractures and relevant AO. Double-screw dens fixation seems to reduce the complication rate.

The aim of this study was to provide morphological data of endplates for the redesign of cervical artificial disc for use in the middle and lower cervical spine (C3-C7). ⋯ The majority of SEPs were flat, while almost all IEPs were curved. The curvature radius of IEPs has a gradually increasing trend from C3 to C6. The average sagittal disc angles, MTDs of the SEPs and IEPs significantly increased from C3 to C7. Based on the above, the current cervical artificial disc design does not sufficiently match the morphology of cervical endplates (CEPs). This mismatch may lead to some postoperative complications of cervical disc arthroplasty.

To review the ability of various types of external immobilizers to restrict cervical spine movement. ⋯ Soft collars have a poor ability to reduce mobility of the cervical spine. Cervico-high thoracic devices primarily reduce flexion and extension, but they reduce lateral bending and rotation to a lesser degree. Cervico-low thoracic devices restrict lateral bending to the same extent as cervico-high thoracic devices, but are considerably more effective at restricting flexion, extension, and rotation. Finally, cranio-thoracic devices nearly fully restrict movement of the cervical spine.

Review Practice Guideline
Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.
To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD). ⋯ For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.
