1- When is rhizolysis indicated?
It is indicated for lumbar or cervical pain that has not improved with medication or physiotherapy and is not suitable for another type of surgical intervention.
2- Results of rhizolysis
It is effective in 50% of cases for 6 months to 2 years. This is because the nerve regenerates and pain may return. In 25% of patients there will be some pain relief for a shorter period. Therefore, positive results occur in up to 75% of cases.
3- When does the effect of rhizolysis begin?
Pain relief may take 2 to 3 weeks to reach its maximum effect. However, complete pain relief is unlikely, as not all pain originates in the joints. In a small number of patients the procedure may have no effect, and there is a 5% risk of permanent worsening of pain.
4- What does rhizolysis involve?
It is a procedure performed on the nerves of the spinal joints that transmit pain signals. It uses a radiofrequency technique applied through a special needle. The heat generated at the needle tip will disable the nerves responsible for your pain. The procedure aims to provide long-term relief.
5- No hospital admission required
This is a 30-minute outpatient procedure (no admission required; you go home after one hour), performed under local anesthesia.
6- Possible complications
Complications are very rare, as thorough checks are performed during the procedure to affect only the sensory nerves responsible for pain.
7- Recovery after rhizolysis
There is no strict recovery period. You will only be advised to avoid strenuous activity for two days.
