We performed 20 cases of opponensplasty from Oct. 91 to Apr. 94 at National Medical Center, and analyzed its results according to new assessment criteria invented by authors, and evaluated the efficacy of the operative treatments.
@ES The results were as follows :
@EN 1. The patients were 9 males and 11 females, average age was 48 years, old, and average duration of paralysis was 28 years. The mean follow-up period was 2.8 years. And most common type of nerve affection was combined low median and high
