Scaphocapitate Fracture Syndrome in an Adolescent: A Case Report, Diagnosis, and Surgical Treatment

Scaphocapitate fracture syndrome, or Fenton syndrome, is a rare condition characterized by fractures of the scaphoid and capitate bones, often with a 180-degree rotation of the proximal capitate, and is frequently underdiagnosed due to its rarity and inconclusive initial radiographic findings. We report the case of a 15-year-old boy who sustained a high-energy wrist injury after a three-meter fall. Initial X-ray raised suspicion of a scaphocapitate fracture syndrome; therefore, the patient was referred for a CT scan. He returned with the results two months later, which confirmed scaphocapitate fracture syndrome. Surgical management involved open reduction and internal fixation of the scaphoid and capitate fractures, repair of the iatrogenic lunate fracture, and external fixation for stability. Postoperative recovery was satisfactory with complete fracture healing, no avascular necrosis, and minimal functional limitations at the five-year follow-up with a Modified Mayo Wrist Score of 100 out of 100 points. This case highlights the importance of high clinical suspicion, advanced imaging for accurate diagnosis, and anatomical surgical fixation to ensure alignment and favorable long-term outcomes.
