   Introduction
 
Postoperative nerve palsy associated with revision total hip arthroplasty is a serious neurologic complication, occurring in up to 50% of cases. While a variety of intraoperative monitoring techniques have been used to reduce the prevalence of this complication, they are not sensitive or accurate enough to prevent surgical damage to the sciatic nerve. A new, modified intraoperative montage utilizing spontaneously elicited electromyography (sEMG) and near-nerve action potentials (NAPs) was evaluated in a retrospective review of thirty-five consecutive revision total hip arthroplasties.

SEMGs were recorded from sterile needle electrodes placed in the tibialis anterior, extensor hallucis longus, and gastrocnemius muscles of the involved extremity. NAPs were obtained from needle electrodes placed near the peroneal nerve (knee) and tibial nerve (ankle). Audible recordings were monitored, and the surgeon was informed of the location and stimulus of physiologically important occurrences.

Four incidents of sEMG firing and one episode of NAP occurred during surgical . . . [Full Text of this Article]
