Ulnar nerve laceration and repair.

Patient age, the site and extent of the injury, and the delay of treatment significantly influence the outcome after repair of ulnar nerve injuries. Ulnar nerve repairs in older patients, high-level injury, and delayed cases may result in a poor prognosis. High-level lesions and lesions that are close to the elbow can also benefit from nerve transposition. Splinting in wrist flexion and/or elbow extension with carpal tunnel and Guyon's canal releases are necessary for lesions that are closer to the wrist. Arterial repairs combined with nerve repairs especially in low-level injury can provide superior outcomes.
