Abstract

Objective To explore the clinical treatment of deep branch of ulnar nerve injury. Methods From January 2013 to August 2018, 20 cases of deep branch of ulnar nerve injury were treated. The etiology, diagnosis and surgical treatment of deep branch of ulnar nerve injury were analyzed retrospectively. Results All the patients were follow-up for 8.9 to 68.1 months with an average of 37.0 months. According to the criteria of upper extremity functional evaluation issued by the Hand Surgery Society of the Chinese Medical Association, the results were rated as excellent in 11 cases, good in 4 cases, fair in 4 cases and poor in 1 case. Conclusion The injury of the deep branch of ulnar nerve requires early diagnosis and early surgical treatment. The effect of nerve suture or neurolysis is related to the degree of neurodegeneration or intrinsic myofibrosis. Key words: Ulnar nerve; Treatment outcome; Deep branch; Diagnosis; Surgical treatment
