Migration of Rod: A Case Report of Rare Complication of Minimal Invasive Surgery in Spinal Trauma with Narrative Review of Literature.

Introduction: Traumatic spine injury is one of the leading causes of morbidity and mortality in trauma patients. Open surgical procedure is associated with increased blood loss, surgical trauma, and increased recovery period. The goal of minimally invasive surgery (MIS) is to minimize iatrogenic trauma caused by open surgery.

Case Report: A 39-year-old female patient presented to us with complaints of severe pain in back following a fall from ten feet height 1-day back. She was diagnosed with L1 burst fracture and was managed by indirect fracture reduction and posterior instrumented stabilization from D12 to L2 by MIS. She presented to us with complaints of pain over back after 3 months of index surgery. Neurology was intact, and ESR and quantitative CRPH were normal. X-ray showed downward and outward displacement of left connecting rod with pedicle screws in situ.

Conclusion: Minimal invasive surgery in spine is associated with steep-learning curve and technical challenges. Mechanical complications associated with implants should be always kept in mind while planning the surgery.
