Ganglion cysts are small sacs of fluid that form over a joint or tendon. The cause of ganglion cysts is not known although one theory suggests that trauma causes the tissue of the joint to break down, forming the cyst.
A bump/mass presents, that can change size and is usually soft and doesn’t move. It may appear over time, suddenly reduce or disappear entirely. There can be pain with movement, particularly bending the wrist backwards.
Although ganglion cysts are not harmful, they may need surgery to remove them if painful. This is often the case with ganglions on the back of the wrist. After surgery a splint and specific exercises are required to ensure return of movement, strength and function. Your hand therapist can assist you with these interventions.
If you are experiencing any of these symptoms, book an appointment.
