Wrist cyst

Ganglion cyst is a bump full of liquid coming from the joint or tendon's sheet. In most cases the cyst appears at the dorsum of the wrist, less frequently volarly or at the base of the thumb.
These cyst are benign; they could cause pain after repetitive movements of the involved regione. Their sizes might change with time and sometime disappear temporary. Clinical observation is sufficient for the diagnosis; sometime an ecography might be useful.

Treatment
If the cyst is not painful and does not affect movements no treatment is necessary. On the contrary surgery may be needed. The cyst can be excised either through a traditional open approach or in specialized centre arthroscopically. The operation is performed under brachial plexus anaesthesia in day surgery regimen.
Recurrences, even if rare, are described.
