How to treat median nerve injury?

summary

The median nerve is superficial at the wrist and is easily injured by sharp instruments. Supracondylar fracture of humerus and lunate dislocation are often combined with median nerve injury, mostly contusion or crush injury. Secondary to shoulder dislocation is traction injury. In addition, the median nerve may produce chronic nerve compression symptoms due to hyperosteogeny of wrist, hypertrophy of transverse carpal ligament or hypertrophy of pronator teres. How to treat median nerve injury? Let's talk about my views.

How to treat median nerve injury?

Treatment 1: for open injury, we should strive to repair in one stage. Delayed one-stage repair can be performed for those with irregular nerve ends, severe contusion, or severe wound contamination. For closed nerve injury, the patients with mild degree should be observed for 1-3 months. If there is recovery, surgery is not necessary. If there is no recovery, surgery should be performed immediately.

Treatment 2: when the nerve defect is less than 2 cm, it can be overcome by flexing the wrist joint and dissociating the proximal and distal nerve trunk, but the maximum flexion angle is 20 ° The best free range is 2-3cm. Too much dissociation will affect the blood supply of nerve stump. When the nerve defect is more than 4cm, the nerve transplantation should be done. If the tourniquet is not sure, the nerve transplantation should be done.

Treatment 3: when combined with soft tissue defect, it is not suitable to suture by force. If the soft tissue condition is good, skin grafting or flap transfer is feasible. For patients who need flap transfer, if there are many nerve defects, the flap should be repaired first and the nerve transplantation should be performed in the second stage.

matters needing attention

Capsicum: capsicum is a kind of food with strong irritation. It is easy for patients with nerve injury to stimulate nerves after eating, and cause local swelling, inhibit the repair of nerve cells, and affect the recovery of patients. It is advisable to eat light food such as vegetables and fruit food Baijiu: Baijiu contains alcohol, which is easy to stimulate nerve fibers, inhibit nerve repair, and is not conducive to the recovery of patients' body. Should eat non-alcoholic and other stimulating ingredients of the drink.
