TY - JOUR AB - The aim of this case report is to present a rare case of acute slipped femoral capital on a chronic slipped capital femoral epiphysis (SCFE) after spinal fusion due to idiopathic scoliosis. A 14 year old male patient underwent posterior spinal fusion due to idiopathic thoracic scoliosis. Post‑operatively, the patient presented with acute pain in the left hip and a reduced range of motion, which revealed acute SCFE. The patient was then referred to the Second Orthopaedic Department of Agia Sofia Children Hospital in Athens, and underwent percutaneous pinning of the left femur, after which he was discharged uneventfully. The follow up was excellent with no impact on the patient's daily life. The case described is extremely rare in the current literature. The significance of the pre‑operative planning is underlined by this case, as well as the need for the spinal surgeon to be aware of the possibility of acute pain in the hip in young adolescents, as SCFE is more common amongst this demographic.
