What are the treatments for stenosing tenosynovitis?

There are relatively many treatment options for stenosing tenosynovitis, the common ones being the following.
Strictly conservative treatment, the affected finger should be braked and immobilised in a plaster cast for a short period of time. Localised microwave physiotherapy, blood-activating medication and also topical non-steroidal anti-inflammatory drugs are also administered.
Local closure treatment with tretinoin is more effective.
If there is still no effect after these 2 strictly conservative treatments, surgery may eventually be considered.
