Resumo

Objetivo Comparar os resultados funcionais entre pacientes com fratura complexa do úmero proximal submetidos a artroplastia reversa com tubérculos consolidados e tubérculos não consolidados. O objetivo secundário foi determinar a taxa de consolidação dos tubérculos com este tipo de prótese.

Métodos Estudo de tipo coorte, retrospectivo, com coleta prospectiva de dados. No total, 28 pacientes cumpriram os critérios de inclusão: idade superior a 65 anos, prótese reversa do ombro por fratura complexa do úmero proximal (3 ou 4 partes, segundo Neer), e tempo de seguimento mínimo de 24 meses. Aos seis meses, todos os pacientes foram avaliados radiograficamente quanto à consolidação dos tubérculos e divididos em dois grupos: grupo com tubérculos consolidados e grupo com tubérculos não consolidados. A avaliação funcional realizou-se segundo o sistema de pontuação de Constant, da amplitude de movimento ativo, e da Escala Visual Analógica (EVA) à data da última consulta. Registaram-se todas as complicações.

Resultados A consolidação dos tubérculos ocorreu em 21 pacientes (76,3%). Verificou-se diferenças estatisticamente significativas no sistema de pontuação de Constant (p < 0.001), elevação anterior (p = 0.020), rotação interna (p = 0.001) e externa (p = 0.003), quando se comparou o grupo dos tubérculos consolidados com o grupo dos tubérculos não consolidados. Não houve diferenças significativas na EVA entre os 2 grupos.

Conclusão A consolidação dos tubérculos traduz uma melhoria dos resultados funcionais em pacientes submetidos a artroplastia reversa do ombro como tratamento de fraturas complexas do úmero proximal em idosos.
