significance of regional denervation in the development of inguinal hernia

ABSTRACT

Electromyographic studies of the most inferior fibers of the transverse abdominis muscle were performed upon 30 inguinal hernias patients. EMG abnormalities signifying partial denervation were found in only three patients. They did not correlate with previous abdominal incisions. The low frequency of this abnormality in this series is taken as evidence that relative denervation does not play a significant role in the development of primary inguinal hernias
