Plantar nerve necrosis is diagnosed primarily on the basis of symptoms and ancillary tests, particularly EMG findings of loss of nerve conduction.
Necrosis of the plantar nerve may present with numbness, abnormal sensation, and sensory loss of the plantar foot, with no sensation of heat, cold, or pain, and is usually caused by a history of trauma or chronic compression of the plantar foot.
Electromyography can also be used to determine whether there is any evoked potentials in the plantar nerve injury. If there is no nerve conduction, it means that there may be nerve necrosis.
To address the causes of nerve necrosis, local decompression, nerve release, the application of nutritive drugs such as rat nerve growth factor to promote nerve recovery, but the recovery of nerve necrosis is very slow.
The occurrence of the above symptoms need to go to the hospital in time for further examination and standardized treatment under the guidance of the doctor.
