Endoscopic Ganglionectomy of the Elbow

Resection of the ganglion of the elbow is indicated if the size or location of the cyst impairs function or causes significant pain. Arthroscopic decompression or endoscopic resection of the cyst is the minimally invasive surgical option. It has the potential advantage of better cosmetic results and less soft-tissue dissection. Endoscopic resection is indicated if the cyst is not communicating with the joint or the communication is not identifiable arthroscopically or if there is a long and narrow communication placing the cyst away from the elbow joint. Preoperative magnetic resonance imaging is essential for surgical planning.
