The study investigates the risk of nerve injury during subtalar arthroscopy by examining the distance to the superficial peroneal and sural nerves near common arthroscopic portals.*
-
Using 40 foot-and-ankle specimens, the researchers identified the proximity of surrounding nerves to three portal types: anterolateral (AL), posterolateral (PL), and accessory anterolateral (AAL).*
-
Conclusions indicate that while AL and AAL portals can be safely placed with careful technique, the sural nerve near the PL portal is at the highest risk for injury, emphasizing the need for surgeons to adhere to defined "safe zones."*
