Objective To evaluate the clinical efficacy of occipitocervical decompression and cer- vifix system internal fixation on Arnold - Chiari I malformation. Methods The 12 Arnold - Chiari Ⅰ cases in our department from April 2005 to April 2010 were treated with occipitocervical decompression and Cervifix system internal fixation. Clinical nervous function recovery was analyzed retrospectively through JOA score before and after operation, and during a follow - up period of 1 year. Meanwhile, the excellent and good ratios after operation, and the clinical effectiveness during the follow -up period were evaluated. Results Good function recovery was found after operation and during one - year follow - up period. JOA score was elevated from pre - operative day 7.7 to post - operative day 12.9. Excellent and good ratios were 83.3%. Average JOA score was 13.4 after 1 - year follow - up.
