Progressive Non-infectious Anterior Vertebral Fusion (Copenhagen Syndrome); A Case Report and Literature Review

Progressive anterior vertebral fusion (pavf or copenhagen syndrome) is a very rare cause of pathologic kyphosis that gradually and progressively leads to anterior vertebral fusion. in this report, we described a 13-year-old girl with pavf presented to the orthopedic clinic of imam reza hospital with rigid thoracic kyphosis (90°) in 2019. she underwent two stages anterior and posterior spinal surgery and was finally discharged with a normally aligned spine and good general condition. in pediatric patients presented with thoracic or thoracolumbar kyphosis, in addition to the common diseases that cause kyphosis, pavf should also be considered.
