He had undergone earlier surgery for an elbow injury at 6 years of age. Revision surgery for nonunion was performed using an extra-articular method combining cylindrical bone graft and headless screw fixation. Partial union was observed, and he resumed sports after 3 months, with his limb largely pain-free and functional. At the 21-month follow-up, bone healing was complete.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n
