The specific treatment methods for ulnar nerve injury are as follows: 1, for closed ulnar nerve injury, early plaster fixation is required and observation is sufficient, which can usually heal spontaneously; 2, for ulnar nerve injury caused by trauma, you need to go to a professional microsurgery hospital or orthopedic hospital for microscopic episcleral and bundle membrane suturing, postoperative plaster fixation, and complementary symptomatic treatment with nerve-nourishing drugs; 3, for ulnar neuritis, that is, elbow canal syndrome, you need to go to a regular hospital for release.
