Sequential Compression Device May Cause Peroneal Nerve Palsy

Abstract

This article presents 2 cases of foot drop after joint replacement surgery that presented after sequential compression device application. In both cases, intact peroneal nerve function was documented by the surgeon in the recovery room prior to sequential compression device application. We believe that excessive pressure over the superficial aspect of the peroneal nerve in conjunction with decreased pain stimulus from analgesia may have contributed to these complications. We maintain sequential compression devices are the current mechanical thromboprophylaxis of choice; however, 4 recommendations are made to minimize the chances of this potential complication. First, precise attention should be given to patients who are short statured, as these patients can be more susceptible to having a sequential compression device improperly placed over the peroneal nerve at the fibular neck. Second, we recommend different size options become more widely available to accommodate varying patient sizes such that placement of the device is ensured to be distal to the fibular neck. Third, when using sequential compression device brands that have hook and look fastener straps, the straps should not be tight on application and frequent skin checks should be made to look for signs of over-compression. Lastly, we recommend considering delaying postoperative application of the sequential compression device until resolution of sensation following spinal or epidural anesthetic.
