OBJECTIVE: To explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating @entity179 . METHODS: The clinical data of 46 @entity1 with @entity179 treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38  11.63) years. Operation section was in L2-L5 of 16 @entity1 (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 @entity1 (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). @entity1 were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and @entity717 Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All @entity1 underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded. RESULTS: All @entity1 were followed up from 16 to 48 months with the mean of (23.23  7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg @entity158 were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05). CONCLUSION: The preliminary clinical results of the Dynesys system combined with PLIF in the treatment of @entity179 are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.
