After anterior cervical discectomy, fusion was radiologically, biomechanically, and histologically assessed in a sheep spine fusion model. ⋯ The MCM alone is not able to replace autologous bone grafts. Early activation of the platelets by calcium, which is released from mineralized collagen, could be the reason for the insufficient osteoinductive effect of PRP. In consequence, the combined application of mineralized collagen and PRP had no significant osteoinductive effect in this model.

Acute cervical fractures in ankylosing spondylitis: an opportunity to correct preexisting deformity.
A new technique for the management of traumatic cervical fracture in patients with chin-on-chest deformity in ankylosing spondylitis is presented. OBJECTIVE.: To present a new surgical technique for acute deformity correction through cervical fractures in the setting of kyphotic deformities. ⋯ Surgical extension osteotomy in the lower cervical spine through the fracture site using the anterior lengthening bar-halo extension brace seems to be a safe method for correcting spine flexion deformity in ankylosing spondylitis after traumatic fracture.

Analysis of patient-level diagnostic and cost data from an administrative database. ⋯ SCI entails costly hospital care and high risk of hospital-acquired illness. Some of these complications are preventable. Better understanding of the financial costs of these episodes can assist healthcare providers and funders to weigh the benefits of interventions to reduce the rates of complications in these vulnerable patients.

Reliability and validity of the persian version of the scoliosis research society-22r questionnaire.
Cross-sectional validation study to investigate psychometric properties of adapted Persian version of the Scoliosis Research Society-22r (SRS-22r) questionnaire. OBJECTIVES.: To translate the SRS-22r into Persian and to evaluate the internal consistency, reliability, and validity of the Persian SRS-22r. ⋯ The Persian version of the SRS-22r has satisfactory reliability, convergent validity, and discriminant validity to measure health-related quality of life in adolescent patients with scoliosis in Iran. It is simple and easy to use and now can be applied in clinical settings and future outcome studies in Iran.

A prospective validation study, preliminary single-center report. ⋯ The result of this study demonstrates improved capture of surgical AEs using SAVES. Excellent interobserver reliability between surgeons at different level of training was demonstrated with minimal education or training regarding the use of SAVES.
