Resumo

Introdução: A sinostose tibiofibular (ST) é uma alteração anatômica rara caracterizada pela fusão óssea entre tíbia e fíbula. Quando localizada na região diafisária, denomina-se sinostose tibiofibular diafisária (STD). A ST pode estar associada a osteocondromas múltiplos, condição autossômica dominante rara, e constituir causa de dor no compartimento anterior da perna, especialmente em atletas, decorrente de microfraturas repetitivas e alteração biomecânica da fíbula durante a marcha. Objetivo: Relatar um caso de sinostose tibiofibular diafisária (STD) de morfologia trapezoidal em ossos secos, correlacionando com suas implicações anatômicas, biomecânicas e clínicas. Relato de Caso: Durante atividade acadêmico-científica no Laboratório de Anatomia da Universidade Federal de Sergipe, foi identificada uma STD no membro inferior esquerdo, localizada no terço médio da perna. A ponte óssea trapezoidal originava-se na superfície lateral da tíbia com altura máxima de 28 mm, afilando-se progressivamente para 23 mm na porção intermediária e 21 mm na inserção fibular. As larguras superior, média e inferior eram de 15 mm, 12 mm e 7 mm, respectivamente, totalizando área aproximada de 261 mm². A margem superior apresentava curvatura regular com concavidade cranial; a margem inferior exibia contorno irregular com espícula óssea adjacente à fíbula. Foram observadas áreas de calo ósseo sugestivas de fraturas prévias, indicando etiologia pós-traumática. Conclusão:  A STD é uma condição rara, relevante em atletas, cujo conhecimento é essencial para o diagnóstico diferencial e manejo clínico da dor na região anterior da perna.
