\u003cp\u003eCare of spinal conditions has become increasingly complex and confusing. Classification systems can help in understanding the subject matter at hand, but have exploded in numbers and complexity. Attempts at extracting classifications of spinal disorders are cumbersome and require careful study of numerous reference books without achieving a comprehensive overview in the end. This one of a kind reference text summarizes over 185 spine classification or severity easures with standardized art work, provides ratings and critical evaluations of pertinent strengths and weaknesses in a concise and systematic fashion and provides help in:\u003c/p\u003e\u003cul\u003e\u003cli\u003eStudying spinal disease conditions \u003c/li\u003e\u003cli\u003ePreparing informed treatment decisions \u003c/li\u003e\u003cli\u003eCommunicating individual patient disease severity \u003c/li\u003e\u003cli\u003eEvaluating publications regarding treatment results and success \u003c/li\u003e\u003cli\u003eFormulating spinal research projects \u003c/li\u003e\u003cli\u003eProviding a scientific reference tool\u003c/li\u003e\u003c/ul\u003e\u003cp\u003e\u003cstrong\u003eThe book is divided into two major systems\u003c/strong\u003e\u003c/p\u003e\u003cp\u003eDisease severity:\u003c/p\u003e\u003cul\u003e\u003cli\u003eGeneral disease severity\u003c/li\u003e\u003cli\u003eInstability \u003c/li\u003e\u003cli\u003eOsteoporosis \u003c/li\u003e\u003cli\u003eStenosis\u003c/li\u003e\u003cli\u003eSpinal deformity\u003c/li\u003e\u003cli\u003eDegenerative disorders \u003c/li\u003e\u003cli\u003eInfection\u003c/li\u003e\u003cli\u003eTumor \u003c/li\u003e\u003cli\u003eHeterotopic ossification \u003c/li\u003e\u003c/ul\u003e\u003cp\u003eTrauma severity:\u003c/p\u003e\u003cul\u003e\u003cli\u003eGeneral trauma scores \u003c/li\u003e\u003cli\u003eSpinal cord injury \u003c/li\u003e\u003cli\u003eFracture classifications \u003c/li\u003e\u003c/ul\u003e\u003cp\u003eAll identified measures within each category are formally reviewed and displayed in a unique visually friendly manner containing:\u003c/p\u003e\u003cul\u003e\u003cli\u003eA one of a kind compendium of high quality diagrams for each severity measure or classification system with unrivaled specificity and detail \u003c/li\u003e\u003cli\u003eThe content of each measure and whether it incorporates the critically important ABCDs of disease severity including: an anatomical component, a biomechanical component, a clinical component, and the degree of severity component\u003c/li\u003e\u003cli\u003eA summary of the measures validity, reliability, and predictive ability with corresponding patient populations \u003c/li\u003e\u003cli\u003eAn evaluation of each measure using our scoring criteria focusing on methodological rigor and clinical utility \u003c/li\u003e\u003cli\u003eAn overall score for each measure rating the instrument's strength with respect to methodology and clinical utility\u003c/li\u003e\u003c/ul\u003e
