San Francisco Podiatrist – Cryosurgery
Cryosurgery, also called cryoablation and cryoanalgesia, involves the use of extremely cold temperatures to treat the pain and affected tissues of a variety of foot conditions. The treatment is minimally invasive and selectively eliminates nerve endings in problem areas using small amounts of nitrous oxide under significant pressure. It can be used to treat plantar fasciitis, bursitis, neuromas, neuritis, and plantar fibromas. Cryosurgery is usually opted for following the failure of more conservative treatments such as orthotics, splints, medications, physical therapy or injection therapy. This method has been used in podiatry since 2003 when it was approved by the FDA.
Physicians use a cryoprobe to target the areas that are most painful to the patient. A general anesthesia is applied to the area, and a tiny incision is made to allow insertion of the probe. The treatment usually involves several short cycles of nitrous application over a few minutes. Recovery is relatively simple and quick. A few days of limited activity allows the incision to heal, along with anti-bacterial ointment, clean bandages and anti-inflammatory medication if needed.
