We report successful management of femoral shaft nonunion using patient-specific 3-dimensional (3D) planning in a patient with OI. A 30-year-old woman with type 3 OI presented with an atraumatic femoral fracture progressing to nonunion. There was a severe deformity with narrow canal that complicated fixation. Preoperative 3D modelling guided corrective osteotomy and intramedullary fixation. She achieved pain resolution, functional recovery, and radiographic union at 12 months postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
