Neurolysis is a the breaking down or freeing up of nerve tissues via radiofrequency (heat), chemoneurolysis (chemical), or cyroablation techniques. This can be a permanent or temporary change. These techniques cause Wallerian degeneration of the nerve axon distal to the lesion. The nerve degeneration interferes with the the transmission of nerve signals. eg nerve fibers carrying nociceptive signals are interrupted resulting in pain relief.
- External neurolysis is releasing scar tissue from the nerve
- Internal neurolysis is releasing the compressed tissue.
Indications[edit | edit source]
Patients need to carefully selected. Evidence suggests that it is best used for pain that is primarily somatic in origin. Visceral or neuropathic pain treatment is less valid.
Neurolysis can be used for egs:
- Low back pain and Sciatica results from research for epidural neurolysis for sciatica have been promising, as have radiofrequency neurolysis of the medial branch of the dorsal root for the treatment of axial facet-related back pain.
- Brachial plexus injuries
- Quadrilateral space syndrome
- Peroneal nerve palsy (foot drop). Peroneal is the third most common neuropathy after median and ulnar.
Radiofrequency ablation often provides temporary relief from back pain, unfortunately the relief typically lasts for three to six months and then comes back. Watch this 2 minute video learn more.
Post-Op Management[edit | edit source]
Early management[edit | edit source]
- Pain control
- Oedema management
- Immobilisation may be advised by the surgeon.  There is no general consensus in the research if the limb should be immobilised or not, and if so, the duration of immobilisation. 
Rehabilitation[edit | edit source]
Promoting nerve regeneration requires a varied treatment plan, aiming for sensory and motor cortical remapping. This can include:
- Strengthening exercises
- Manual therapy
- Neuromuscular electrical stimulation
- Combined neurocognitive training
Complications[edit | edit source]
