If you require treatment, surgery is the option.
The lesion should not be treated by simple excision alone as this does not address the source and recurrence is assured.
It requires a synovial debridement of the distal interphalangeal joint combined with excision of the ganglion. As a result of the thinning of the overlying skin, commonly a local flap or skin graft is required.
It is usually done under local anaesthesia (ring block) so patient is awake as a day case.
What to expect after surgery?
A small splint is made for the finger which you wear for about a week to two weeks. Antibiotics and pain killers are also prescribed.
What are the risks of the surgery?
This include infection, recurrence, mallet deformity because of damage to the extensor tendon insertion
