What is Nerve Repair and Regeneration?

Peripheral nerves attach your brain and spinal cord to other body parts including your muscles and skin. These nerves are delicate and easily damaged, making it difficult for the brain to interact with muscle cells. Nerve repair and regeneration products include biomaterials and neuro-stimulation and neuromodulation devices. When a nerve is injured, it is often difficult to get it back to work quickly enough to restore function. But now researchers say they can speed up this process, such that damaged nerves can be healed in days instead of months. The experts suggest to have developed a technique that easily reconnects the disconnected ends of a nerve, enabling it to continue carrying messages.

The level of recovery of your nerve depends on a variety of elements:

  • Age
  • Type of injury
  • The duration since the injury
  • The type of repair
  • The type of nerve

How long does it take to regenerate my nerves?

Regeneration time depends on how deeply your nerve has been injured and the type of injury you have suffered. If your nerve is damaged or deeply affected but not cut, it should recover for 5-13 weeks. The nerve that is cut will grow at 1 mm per day, after about 5 weeks of rest after your injury. Some people have seen continuous improvement over many months. Sensory nerves are more resilient than motor nerves and may recover sensation months or even years after damage.

Classification of Nerve Injury:




Technique of Nerve Repair:

Time to prepare: The nerve ends are prepared to have clear ends by removing necrotic tissue with blades and leaving two normal-looking ends. Flexing the joint above the nerve injury and shortening of the bone can be given more length if this is required.

Accurate estimate: By applying sufficient stress, the nerve ends are mobilised and pulled together, leaving a small distance. Tensionless repairs have shown better results. During approximation, nerve ends can be mobilised, but extensive interfascicular dissection should be avoided.

Consistency: Blood vessels must be aligned to ensure proper rotational alignment.

Maintenance: The nerve repair is maintained by stitching into the epineurium, non-absorbable sutures. It is therefore the epineural repair that keeps the repair together. Sutures need to be placed to prevent the nerve ends from rotting.

Full Report:


In the nervous system, regeneration and repair relates to the process of damaged tissue regrowing or renewing, eventually contributing to the restoration of nervous system function. This process occurs more easily with nerve cells, neurons, brain regions, and immune cells in the peripheral nervous system.
