Objective: To summarize the literature on the electrophysiology of Cavanagh Syndrome (CS), to present a clinical application and to propose an updated electrophysiologic protocol.
Methods: A systematic literature search for CS was carried out and a clinical application is presented.
Results: CS is characterized by congenital thenar hypoplasia and can be associated with other regional muscular and vascular anomalies. The main electrophysiologic abnormality in patients with CS is a reduced amplitude median compound muscle action potential (CMAP) to the thenar eminence, which is also seen in CTS. Radiographic, and electrodiagnostic findings of a patient with co-morbid CS and CTS is presented. Evaluating the median CMAP to the first lumbrical may assist with the diagnosis of CTS in patients with CS.
