Checkpoint: Clarifying Concepts in NCS: Instrumentation, Troubleshooting and Neuroanatomy-Dr. Norbury Presentation

Dr. Norbury Presentation

Pdf Summary

The document appears to be a presentation or guide on nerve conduction studies of the upper limb by Dr. John Norbury, scheduled for 2024. It primarily focuses on the median and ulnar nerves, specifically discussing conditions like carpal tunnel syndrome (CTS) and Martin-Gruber anastomosis. The document provides insights into the anatomical structures, clinical symptoms, and diagnostic procedures related to these nerves.<br /><br />For carpal tunnel syndrome, the presentation outlines the contents of the carpal tunnel, clinical symptoms, and methods for grading the severity of CTS. It also addresses what steps to take when CTS is suspected but routine nerve conduction studies (NCS) return normal results, including special studies like transcarpal, digit 1 and 4, and Robinson methods.<br /><br />Regarding Martin-Gruber anastomosis, three findings are highlighted in conjunction with CTS: increased proximal amplitude, very high conduction velocity, and a positive deflection on proximal stimulation.<br /><br />For the ulnar nerve, the document details its anatomy and the relevant clinical findings. It also provides guidance on diagnostic procedures when an ulnar issue is suspected but routine conductions are normal, recommending motor recording from the first dorsal interosseous (FDI), and testing the dorsal ulnar cutaneous and medial antebrachial cutaneous nerves.<br /><br />Additionally, the document includes logistical details about feedback collection via the AANEM app, encouraging attendees to provide feedback to help improve future meetings. It also outlines how attendees can claim their credits by recording session attendance through the app, with instructions on additional steps for self-assessment and CNCT Checkpoint courses.<br /><br />Dr. John Norbury discloses no financial ties, indicating an unbiased presentation.
