Intraoperative SSEP Monitoring of Circular External Fixation for Revision of Brown Rotationplasty
摘要
A 7 year old female born with proximal focal femoral deficiency (PPFD) underwent femoral rotation/adduction osteotomy and circular external fixation to revise unsuccessful femoro-pelvic fusion rotationplasty and subsequent rotation osteotomies. Due to high risk of neurovascular complications, intraoperative somatosensory evoked potential (SSEP) monitoring of tibial and peroneal nerves was utilized to control safety of acute repositioning of the lower limb during surgery.
