Severe Median Nerve Injured After Local Corticosteroid Injection in A Carpal Tunnel Syndrome Patient ——A Case Report

Background The corticosteroid injection is known to be an effective and safe treatment for carpal tunnel syndrome, no serious complications was reported in previous literature. We report a severe median nerve injured case after corticosteroid injection. Case presentation: A 55-year-old female patient was admitted to our hospital because of numbness in her right finger for 10 years. Total six corticosteroid injections were performed in the past 2 years, and the symptoms did not relief significantly. She underwent ligament resection and median nerve release. The median nerve epineurium thickened and the scar was obvious during the surgery. The patient made a perfect recovery after surgery. Conclusions: The accurate preoperative assessment and personalized treatment are very important for peripheral nerve entrapment disease.
