Why is the top of the foot numb after tendon suture surgery?

Numbness on the dorsum of the foot after tendon suture surgery may have the following causes:

1. Surgical trauma: During the tendon suturing process, the surgery may cause certain trauma to the local tissues, possibly resulting in postoperative numbness. This is a normal postoperative reaction and generally resolves on its own after some time.

2. Impaired local blood circulation: If local blood vessels were damaged during surgery, it may lead to poor circulation, thus causing numbness. This can be improved by promoting blood circulation through methods such as local massage to alleviate symptoms.

3. Nerve damage: If local nerves were accidentally injured during surgery, numbness in the dorsum of the foot may also occur. Minor nerve dysfunction may gradually recover spontaneously, as nerves have a certain capacity for regeneration. However, if the damage is severe, treatment with neurotrophic medications may be necessary.

4. Infection or inflammation: Improper postoperative wound care may lead to infection or inflammation, which can also cause numbness in the dorsum of the foot. Immediate medical examination and treatment are required in such cases.
