Sequelae of Infantile Elbow Infection in an Adolescent: A Case Report with 3D-Printed Assisted Preoperative Planning.

CASE: A 17-year-old adolescent boy with a history of right elbow septic arthritis and osteomyelitis in infancy presented with elbow contracture. He underwent modified Outerbridge-Kashiwagi procedure and radial shortening osteotomy, guided by a 3-dimensional (3D)-printed patient-specific model for preoperative planning and intraoperative reference. At 2 years 8 months postoperatively, range of motion improved by 40° in flexion-extension and 60° in rotation. Transient posterior interosseous nerve (PIN) palsy resolved within 6 months.

CONCLUSION

Infantile elbow infection may cause functional impairment. 3D-assisted modified Outerbridge-Kashiwagi procedure improved motion. Surgeons should be cautious of PIN injury during proximal radius surgery.
