OBJECT: To introduce a novel distraction technique for the treatment of @entity3473 ( @entity3473 ) @entity3029 ( @entity3029 ) via a posterior-only approach. METHODS: Twenty-one consecutive @entity1 with @entity3473 and @entity3029 who underwent posterior distraction reduction and occipitocervical fixation between January 2009 and June 2013 were enrolled in the present study. This novel distraction technique included two steps. First, the distraction between the occipitocervical junction of the rod (OCJR) and the occipital screws was performed to achieve horizontal and partial vertical reduction. Secondly, the distraction was performed between the C2 screws and OCJR to achieve complete vertical reduction. The pre- and postoperative JOA score, the extent of reduction, the fusion status, and the complications were recorded and analyzed. RESULTS: The mean follow-up was 18.3 months with a range of 10-32 months. No @entity1 incurred @entity531 during surgery. The mean JOA score at the last follow-up (15.4) showed significant improvement (P<0.01) compared with the pre-operative parameters (11.2). Complete horizontal reduction was achieved in 18 @entity1 (85.7%), and complete vertical reduction was achieved in 17 @entity1 (80.9%). The rest @entity1 are all received greater than 50% horizontal and vertical reduction. Solid fusion was achieved in 20 @entity1 (95.2%). Mild @entity1282 was observed in two @entity1 . One @entity1 suffered from @entity86 and @entity358 . CONCLUSION: This novel distraction technique may provide satisfactory reduction via a posterior-only approach without exposure of the C1/2 facet joint. Therefore, it is a safe and effective method for the treatment of @entity3473 with @entity3029 .
