Peripheral nerve injuries

Sensation and movement: locating the injury comes first.

What it is

Compression, cuts, stretch or trauma can injure a nerve. Severity depends on the structures damaged.

Sensory loss, weakness, electric pain or difficulty moving may occur. Sudden loss after a wound needs early assessment.

Examination maps the affected territory. Ultrasound and electrodiagnostic tests may help, depending on injury type and timing.

Some injuries are managed with protection, therapy and monitoring. Skin with reduced sensation needs care to avoid unnoticed injury.

Release, repair or reconstruction may be considered. Magnification supports precision but cannot guarantee complete recovery.

Nerve recovery can be slow and depends on injury, distance and elapsed time. Follow-up assesses sensation, strength and daily function.

Does every nerve injury need surgery?

No. Compression, partial injury and transection require different assessment.

Can a cut nerve be repaired?

In selected cases; injury type and timing influence options.

When is nerve testing done?

Timing follows the clinical question; very early tests may not show all changes.

Does microsurgery always use a microscope?

Loupes or a microscope may be used depending on the procedure.

Will sensation return to normal?

This cannot be guaranteed; previous damage and recovery potential matter.

What should I avoid with numb skin?

Avoid burns and prolonged pressure; inspect the skin and seek assessment for new wounds.
