Abstract
A ganglion is the most common soft-tissue mass in the foot and can cause pain, paresthesia, or footwear problems. A ganglion can extend from the dorsum into the plantar compartment of the foot in the form of a horseshoe at the borders of the foot or in the form of an hourglass through the intermetatarsal space. Initial conservative management of a ganglion may entail observation and the use of padding for comfort, manual rupture, aspiration of the cyst contents, and steroid injection or sclerotherapy into the cyst. When the lesion is recurrent or painful, surgical excision is recommended. The purpose of this Technical Note is to describe the details of endoscopic resection of a horseshoe ganglion of the lateral midfoot. This technique has the advantages of being minimally invasive, with better cosmetic results and less surgical trauma to the soft tissue.
