Conclusion: Direct nerve root/rootlet stimulation should be one of the components of MIONM during surgery for tethered cord syndrome to prevent postoperative neurological deficits.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aim: The tethered cord syndrome refers to a variety of lesions that can cause the conus medullaris to be low-lying or incapable of movement within the spinal canal.
📊
Key Findings & Data:Somatosensory evoked potentials (SEPs), motor evoked potentials (MEPs), direct nerve root/rootlet stimulation, free-run electromyography (EMG) and F-waves were used during tethered cord surgery of 10 cases to prevent possible nerve injuries.

Abstract

Aim: The tethered cord syndrome refers to a variety of lesions that can cause the conus medullaris to be low-lying or incapable of movement within the spinal canal. Permanent or temporary neurological complications were reported following surgical release. In this report, peri- and postoperative results in cases with tethered cord syndrome that were followed by multimodal intraoperative neurophysiological monitoring (MIONM) methods are presented. Material and Methods: An IONM system (Nicolet CR Endeavor) was used for monitoring during tethered cord surgery. Somatosensory evoked potentials (SEPs), motor evoked potentials (MEPs), direct nerve root/rootlet stimulation, free-run electromyography (EMG) and F-waves were used during tethered cord surgery of 10 cases to prevent possible nerve injuries. Results: MEP and SEP recordings did not change in any of the cases during surgery. The nervous tissue was identified and differentiated from connective tissue in three cases when motor responses were elicited with direct stimulation of nerve roots. None of the cases had neurological deficits following the operation. Conclusion: Direct nerve root/rootlet stimulation should be one of the components of MIONM during surgery for tethered cord syndrome to prevent postoperative neurological deficits.

Özet

Amaç: Gergin omurilik sendromu, konus medullarisin aşağı yerleşmesine veya spinal kanal içinde hareket etmesine engel olan çeşitli lezyonları tanımlar. Cerrahi serbestleştirme sonrası kalıcı ya da geçici nörolojik komplikasyonlar gözlenebilir. Bu çalışmada, tethered kord sendromu cerrahisi sırasında multimodal intraoperatif monitörizasyon (MİONM) yöntemleri ile izlenen olgularının sonuçları sunulmaktadır. Yöntem ve Gereç: Gergin omurilik sendromlu olguların ameliyatlarının izlemlerinde İONM cihazı (Nicolet CR Endeavor ) kullanıldı. MİONM kapsamında 10 tethered kord sendromlu olgunun ameliyatları sırasında olası sinir hasarını engellemek için somatosensoriyel uyarılmış potansiyeller (SUP), motor uyarılmış potansiyeller (MUP), direkt sinir kökü uyarımı yanıtları, sürekli elektromiyografi, ve F-yanıtları izlendi. Bulgular: Gergin omurilik sendromu nedeniyle opere edilen olguların hiçbirinde MUP ve SUP kayıtlarında ameliyat sırasında farklılık gözlenmemiştir. Üç olguda sinir dokularının konnektif dokulardan ayrımı amacıyla yapılan direkt uyarım ile motor yanıtlar elde edilmesi üzerine ilgili sinir dokuları korunmuştur. Olguların hiçbirinde ameliyat sonrasında nörolojik kayıp gözlenmemiştir. Sonuç: Gergin omurilik sendromu cerrahisinde ameliyat sonrası gelişebilecek nörolojik kayıpları engellemek için direkt sinir uyarımı multimodal intraoperatif nörofizyolojik monitörizasyonun bir parçası olarak kullanılmalıdır.
