Comparison of electrodiagnostic findings in acute traumatic versus chronic non‐traumatic ulnar neuropathy at the elbow

Introduction/Aims A common concept is that traumatic nerve injuries are more likely axonal, and that compressive neuropathies are more likely demyelinating. The purpose of this study was to compare traumatic versus non‐traumatic ulnar neuropathy at the elbow (UNE) to look for electrodiagnostic diffe...

Description
Summary:Introduction/Aims A common concept is that traumatic nerve injuries are more likely axonal, and that compressive neuropathies are more likely demyelinating. The purpose of this study was to compare traumatic versus non‐traumatic ulnar neuropathy at the elbow (UNE) to look for electrodiagnostic differences between the two groups. Methods A retrospective 3 year review of UNE patients at two academic health science centers was conducted. Patients were grouped into acute traumatic UNE versus chronic non‐traumatic UNE based on clinical history. Electrodiagnostic measurements were compared between the two groups. Results There were 50 subjects with acute traumatic UNE and 41 with chronic non‐traumatic UNE. Mean age and sex distribution were similar but those with traumatic UNE had a 7 month duration of symptoms, while those with chronic UNE had 29 month duration (p
