• CASE
    • A 13-year-old obese boy presented with an acute-on-chronic unstable left slipped capital femoral epiphysis (SCFE). He underwent in situ surgical fixation with two 6.5-mm fully threaded cannulated screws. At 6 months, he presented with mechanical failure of both screws. He underwent screw removal, revision in situ fixation, a peritrochanteric flexion and internal rotational osteotomy, and an open femoroplasty. The osteotomy healed at 6 weeks. The femoral physis took an additional year to close.
  • CONCLUSION
    • This case highlights an uncommon complication of in situ pinning of SCFE, discusses revision fixation options, and suggests possible prolonged physeal closure in severe slips.
