Foram avaliados 40 prontu\u00e1rios com tempo m\u00ednimo de acompanhamento de 6 meses; 6 casos foram exclu\u00eddos por n\u00e3o atenderem aos crit\u00e9rios de inclus\u00e3o. As vari\u00e1veis analisadas foram idade, sexo, tempo at\u00e9 a cirurgia, n\u00edvel da fratura, pontua\u00e7\u00e3o do Sistema de Classifica\u00e7\u00e3o de Les\u00f5es da Coluna Vertebral da AO e escore de fraturas osteopor\u00f3ticas (OF). Par\u00e2metros radiol\u00f3gicos, como altura do corpo vertebral e \u00e2ngulos cif\u00f3ticos regionais e segmentares, foram medidos antes e ap\u00f3s a cirurgia. Al\u00e9m disso, a propor\u00e7\u00e3o do corpo vertebral ocupada por cimento foi analisada, com \u00eanfase em sua distribui\u00e7\u00e3o anterior e posterior.<\/jats:p>\n                  <jats:p>Dentre os 34 pacientes, 20 (58,8%) apresentaram resultados satisfat\u00f3rios, ou seja, aus\u00eancia de crit\u00e9rios de falha at\u00e9 o \u00faltimo acompanhamento (grupo 1), enquanto 14 (41,2%) apresentaram falha (grupo 2). A falha foi definida pela presen\u00e7a de fratura vertebral adjacente, colapso vertebral recorrente ou recidiva de dor incapacitante. A cifoplastia gerou melhora significativa na altura do corpo vertebral e nos \u00e2ngulos cif\u00f3ticos. \u00c0 an\u00e1lise de regress\u00e3o, apenas a porcentagem de distribui\u00e7\u00e3o posterior do cimento emergiu como fator preditivo independente de falha (raz\u00e3o de chances ajustada\u2009=\u20091,684; p\u2009=\u20090,012).
