Ganglia are benign but sometimes painful swellings which arise from a joint or tendon sheath. The commonly occur at the wrist and over finger joints and can reflect some underlying degeneration of the joint (arthritis). Where we are sure of the diagnosis and the ganglion is not giving symptoms they can be safely left alone. However frequently they are painful and in this situation can require treatment.
It should be noted that ganglia have a high rate of recurrence with all treatments. Simple aspiration of the ganglion with a needle may be possible or removal of the ganglion with surgery. This will be fully discussed in the clinic prior to treatment planning.
