Aid in surgical planning<br />

Fig. 20.1. Management <strong>of</strong> groin pain: interventional and pharmacologic approaches.<br />

in reporting and study methodologies make it difficult to compare outcomes<br />

between interventions. In general, a stepwise approach is advocated, beginning<br />

with appropriate pharmacotherapy, then progressing to diagnostic<br />

nerve blocks, and finally to therapeutic interventions (Fig. 20.1 ) [27 ]. Early<br />

referral to a pain management physician can help expedite this process and<br />

possibly prevent the transition from acute to chronic pain. For certain<br />

patients, despite the use <strong>of</strong> multiple modalities, pain will not improve substantially<br />

or for any prolonged duration. For these patients, information<br />

from any interventions that at least temporarily lessen their usual pain may<br />

be used to help inform more definitive surgical intervention.<br />
