“…Thoracotomy is a procedure of opening the thoracic wall for chest surgeries, and during posterolateral thoracotomy, the most common approach, surgeons perform incision within the fourth to the sixth intercostal space (ICS) (Bal, Elshershari, Celiker, & Celiker, 2003; Nguyen & Nguyen, 1987; Richelme, Limouse, Ferrari, & Bourgeon, 1984), so the LTN that passes through this area could be injured during the procedure (Lagueny, Reboul, Kien, & Duché, 2014). In Bal et al's (2003) study, 77% of pediatric patients who had undergone surgery for congenital cardiac disease showed scapular winging induced by LTN injury.…”
