Highlights ■ Inflection point agreement was low to moderate amongnon-specialist raters. ■ Thoracolumbar junction showed the lowest inter-observeragreement. ■ Results support the need for protocol standardization and  structured training. ABSTRACT Objective: To assess the intra- and inter-observer reliability of spinal inflection point localization on lateral radiographs of asymptomatic adults using a standardized measurement protocol, given its important role in sagittal alignment analysis and its potential influence on biomechanical interpretation and surgical planning. Methods: This cross-sectional study included 10 adults (five […]

ABSTRACT Objective To gather all systematic reviews of surgical treatment of degenerative cervical diseases and assess their quality, conclusions and outcomes. Methods A literature search for systematic reviews of surgical treatment of degenerative cervical diseases was conducted. Studies should have at least one surgical procedure as an intervention. Included studies were assessed for quality through Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) and Assessment of Multiple Systematic Reviews (AMSTAR) questionnaires. Quality of studies was rated accordingly to their […]

Cistos sinoviais da coluna lombar são uma causa incomum de dor na coluna e radiculopatia, geralmente com evolução gradual dos sintomas, que são secundários ao comprometimento do canal vertebral. Raramente, há hemorragia intracística, que pode se manifestar de forma aguda com síndrome compressiva radicular ou mesmo medular. Habitualmente, os cistos sinoviais associam-se a doença degenerativa facetária, embora a patogênese não esteja completamente estabelecida. Relatamos aqui um caso em que uma complicação hemorrágica em um cisto sinovial no nível L2-L3, adjacente […]
