Retrospective Study of Modified King's Procedure for Cubital Tunnel Syndrome.

From 1981 to 1990. 25 cases of cubital tunnel syndrome were treated by the modified King's procedure, that is medial epicondylectomy with external neurolysis of the ulnar nerve.The ages of the patients at the time of surgery ranged from 14 to 64 years (average, 44.4 years). The follow-up term was 7 months to 10 years and 6 months (average, 3 years and 3 months) after surgery.Using Ikuta's scoring system, excellent results were obtained in 3, good in 7, fair in 11, and poor in 2 elbows. The results were dependent on the duration of their symptoms and the age at the time of surgery.Therefore early diagnosis and treatment is important for cubital tunnel syndrome.
