“…Sciatic nerve monitoring has been used with good results during revision hip arthroplasty [42][43][44]. Motorevoked potentials when used in combination with EMG monitoring identified significant electrical events during acetabular reconstruction, specifically if there was excessive posterior retraction with the hip in flexion [44].…”

Sciatic nerve injuries associated with acetabular fractures may be a result of the initial trauma or injury at the time of surgical reconstruction. Patients may present with a broad range of symptoms ranging from radiculopathy to foot drop. There are several posttraumatic, perioperative, and postoperative causes for sciatic nerve palsy including fracture-dislocation of the hip joint, excessive tension or inappropriate placement of retractors, instrument- or implant-related complications, heterotopic ossification, hematoma, and scarring. Natural history studies suggest that nerve recovery depends on several factors. Prevention requires attention to intraoperative limb positioning, retractor placement, and instrumentation. Somatosensory evoked potentials and spontaneous electromyography may help minimize iatrogenic nerve injury. Heterotopic ossification prophylaxis can help reduce delayed sciatic nerve entrapment. Reports on sciatic nerve decompression are not uniformly consistent but appear to have better outcomes for sensory than motor neuropathy.

“…Intraoperative neurophysiological monitoring is a tool that allows early detection of nerve injuries. Initially it was used in corrective surgery of large spinal deformities an its use has progressively extended to other surgical procedures such as intramedullary spine tumors and prosthetic surgery of the lower limbs [10,14].…”

Background: Oncological femoral or pelvic resections and reconstruction have become an alternative to large amputations. However, one of the frequent risks is the neurological injury. The use of intraoperative evoked potentials allows its control in order to modify the surgical gestures. The purpose of this study was to evaluate the results of intraoperative neurophysiologic monitoring in large reconstructive arthroplasty surgeries. Case presentation: A prospective study (2012-2018) was performed, including 8 patients with 6 complete resections of the femur and 2 resections of the pelvis. In all cases, intraoperative lumbar plexus monitoring was performed using evoked potentials in order to analyze variations during surgery as well as a postoperative control. 100% could be correctly monitored throughout the surgery. In 4 cases, intraoperative anomalies were detected requiring modification of the surgery. Of these, postoperatively only one nerve injury persisted: a complete sciatic nerve injury due to an intraoperative vascular injury. Conclusion: Intraoperative neurophysiological monitoring is a very useful resource in large oncological resection, allowing detection of nerve distress due to manipulation or excessive limb traction during reconstruction. The use of somatosensory evoked potentials in large oncological resections can predict and minimize the risk of relevant postoperative nerve complications

“…Monitoring of lumbosacral plexus is not as frequently done as the brachial plexus. A few reports exist, where individual nerves of the lumbosacral plexus were monitored and mapped, examples being the sciatic nerve MEP in hip arthroplasty (Sutter et al, 2012;Satcher et al, 2003) and SSEP in meralgia paresthetica (Seror, 2004). Obstetric brachial plexus injury is common (approximately 1 in 1,000 live births) and up to 20% to 30% kids may need surgical intervention (Pondaag et al, 2004;Thatte and Mehta, 2011) for recovery.…”

Intraoperative Mapping of Roots, Plexuses, and Nerves

The use of intraoperative mapping of neural structures has come to be an indispensable technique to prevent or minimize postoperative morbidity. In this article, I briefly mention its use in mapping nerve roots, plexuses, and peripheral nerves. The reader may find some mention of monitoring techniques, too, as monitoring and mapping are seldom done separately. I include the technical details of different mapping modalities, relevant anatomy, and clinical applications, as appropriate.
