Posterior Tibial Nerve PRF vs Intralesional RFT for Painful Calcaneal Spur and Plantar Fasciitis

The posterior tibial nerve (PTN) was identified with a 5-12 MHz linear ultrasonography (US) probe at the level of the medial malleolus, where it runs posterior to the posterior tibial artery. Using the in-plane technique, a 22-gauge, 10-cm radiofrequency cannula was inserted under US guidance and advanced until the tip was adjacent to the nerve. Pulse radiofrequency was applied at 42°C for 240 s with a pulse width of 20 ms

The painful heel and calcaneal spur were visualized under lateral fluoroscopy. A 22-gauge, 10-cm radiofrequency cannula was inserted and advanced until the needle tip reached the calcaneal spur tip. When the needle tip contacted the spur, local anesthetic was administered through the cannula and radiofrequency ablation was performed at 80°C for 90 s.
