Treatment of Cervicogenic Headache Concurrent With Cervical Stenosis by Anterior Cervical Decompression and Fusion.
Retrospective study. ⋯ CeH when associated with cervical spinal stenosis of the subaxial spine can improve when stenosis is treated with anterior cervical discectomy and fusion.

Multicenter StudyNovel Angular Measures of Cervical Deformity Account for Upper Cervical Compensation and Sagittal Alignment.
This is a retrospective review of a prospective multicenter database. ⋯ CCA and CPT account for both cervical sagittal alignment and upper cervical compensation and can be utilized in assessment of cervical alignment.

Dysphagia After Occipitothoracic Fusion is Caused by Direct Compression of Oropharyngeal Space Due to Anterior Protrusion of Mid-cervical Spine.
This was a retrospective study. ⋯ Our results demonstrated strong relationships between PTA and the value of dPS, and the incidence of dysphagia. As PTA reflects anterior protrusion of mid-cervical spine, these results indicated that dysphagia after OTF is caused by narrowing of oropharyngeal space due to direct compression from anteirorly protruded mid-cervical spine.

Comparative StudyBiomechanical Investigation of a Novel Revision Device in an Osteoporotic Model: Pullout Strength of Pedicle Screw Anchor Versus Larger Screw Diameter.
In vitro cadaveric biomechanical study. ⋯ Anchor sleeves with 6.5-mm-diameter pedicle screws provided markedly higher resistance to screw pullout than 7.5-mm-diameter revision screws and fixation statistically equivalent to 8.5-mm-diameter screws, possibly because of medial-lateral expansion within the vertebral space and/or convex filling of the pedicle. AS results had the lowest SD, indicating minimal variability in bone-screw purchase.

Correlations Between the SF-36, the Oswestry-Disability Index and Rolland-Morris Disability Questionnaire in Patients Undergoing Lumbar Decompression According to Types of Spine Origin Pain.
Cross-sectional study. ⋯ Moderate correlation was found between ODI or RMDQ as a condition-specific outcome and the SF-36, indicating overall health status. ODI was found to be a more adequate measure to evaluate axial back pain rather than referred pain or radiating pain. RMDQ was adequate to measure the health status and to evaluate the 3 types of spine pain. These 3 instruments could therefore provide the clinician with complementary information about the patient's status.
