Mucous cysts are small, fluid-filled sacs that form on the fingers. They are associated with osteoarthritis (OA) and usually develop in patients aged 50 to 70. These cysts appear between the last joint of the finger and the bottom of the fingernail. When this mucous cyst is in danger of rupturing, it can be surgically removed with attached skin and covered with a dorsal flap. This video was captured using the VITOM system from KARL STORZ.
