Mucous Cyst
This ganglion, also commonly known as mucous cyst, arises from the distal interphalangeal joint and presents as a cystic swelling or blister-like lesion on the dorsum of the distal interphalangeal joint or just on the dorsum of the distal phalanx. It may be the only obvious manifestation of osteoarthritis of the distal interphalangeal joint.
Remember!
It is important not to stick needles into it because it can become a source of infection and lead to the destruction of the joint.
What treatment?
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.
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.
What anaesthesia?
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.
