Sciatic Nerve Palsy Caused by Tourniquet Use After Pediatric Knee Meniscal Surgery.

Sciatic nerve palsy because of tourniquet use in the pediatric population is rare. Here, we present a case of a 13-year-old girl with sciatic nerve palsy caused by tourniquet use after knee meniscal surgery. On the day after the operation, incomplete tibial and complete peroneal nerve palsy was observed. First, a sciatic nerve palsy caused by the tourniquet use and an iatrogenic common peroneal nerve injury caused by the meniscal suture device of lateral menisci was considered. However, the possibility of the iatrogenic common peroneal nerve injury was ruled out based on the examination findings. As a result, we diagnosed the sciatic nerve palsy caused by tourniquet use. The sciatic nerve palsy gradually improved within a week. Finally, the palsy completely recovered at 8 weeks postoperatively.
