Toddler Undergoes Five‑Hour Limb Reconstruction After Year With Broken Leg

Surgeons treated congenital pseudarthrosis in an operation whose success is uncertain and which could lead to further surgery or amputation.

Overview

  • Carson Lees, now two, first fractured his leg in June 2025 when he was about 14 months old and was later diagnosed with congenital pseudarthrosis, a rare condition that causes weak bone and a ‘false joint’.
  • Doctors kept Carson in a clamshell cast for the year he waited to turn two so surgeons could perform a complex reconstruction at Sheffield Children’s Hospital.
  • The limb reconstruction operation lasted more than five hours and used bone graft and reconstruction techniques common in specialist paediatric limb surgery.
  • Carson is recovering at home and remains wheelchair‑dependent while his leg heals, enjoying low‑impact activities such as bowling and small treats from the hospital café.
  • His parents have launched a GoFundMe campaign and plan summer fundraising events to thank Sheffield Children’s Hospital and support the British Limb Reconstruction Society as they face an uncertain prognosis.
