Abstract:

Background and Importance: Intraoperative Neuromonitoring (IONM) plays a pivotal role in surgeries involving the brain, spinal cord, or peripheral nerves. The monitoring of Somatosensory Evoked Potentials (SSEPs) and Motor Evoked Potentials (MEPs) facilitates the assessment of sensory and motor pathways, respectively. Clinical Report: In this case study, the absence of Motor Evoked Potentials in the left Abductor Pollicis Brevis (APB) and left Abductor Hallucis (AHAL) can be attributed to the presence of Martin-Gruber anastomosis between the Ulnar nerve and Median nerve. While such anatomical variations are rare, they can elucidate seemingly unrelated loss of neuromonitoring signals. Conclusion: Being mindful of such exceptions is crucial for neurologists, surgeons, and neuromonitoring technicians, as it provides valuable insights into the interpretation of signals and aids in the explanation of potentially perilous signal losses during surgical procedures.
