A case of superficial peroneal nerve injury during ankle arthroscopy.
We report a case of superficial peroneal nerve (SPN) injury caused by ankle arthroscopy. A 20-year-old woman underwent arthroscopy on her right ankle because of chronic ankle pain after a sprain. After arthroscopy, the patient complained of pain on the dorsum of her right foot and felt a radiating pain from the anterolateral portal to the dorsomedial aspect of her foot. Eight months after arthroscopy, we found that a neuroma had developed on the intermediate dorsal cutaneous nerve, and performed neurolysis of the SPN. Her symptoms gradually decreased after surgery, and had disappeared by 45 months. To avoid such an injury of the SPN, the safest placement of the anterolateral portal is necessary and is, according to our previous anatomic study, 2 mm lateral to the peroneus tertius tendon.
