OBJECTIVE: To investigate the feasibility and the mid-term effects of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion in treating @entity179 . METHODS: From August 2005 to May 2010, 56 @entity1 with @entity179 underwent lumbar posterolateral fusion,their clinical data were retrospective analyzed. The @entity1 were divided into two groups (unilateral group and bilateral group) according to fixation methods,27 @entity1 in unilateral group who were underwent unilateral pedicle screw fixation, including 18 males and 9 females with a mean age of (57.5    7.1) years old (ranged from 41 to 66 years); and 29 @entity1 in bilateral group who were treated with bilateral pedicle screw fixation (on the basis of the above, with contralateral vertebral pedicle screw fixation), including 19 males and 10 females with a mean age of (54.6    5.1) years old (ranged from 43 to 68 years). The clinical data such as operation time, @entity190 volume, hospitalization time and cost were compared between two groups. JOA score system was used to evaluate the neurological function. And fusion status and cage-related complication were also analyzed. RESULTS: All @entity1 were followed up from 36 to 60 months with an average of 45.8 months. No @entity1503 were found during operation. Operation time, @entity190 volume, hospitalization time and cost in unilateral group were better than that of bilateral group (P < 0.05). There was no significant difference in JOA score between two groups (P > 0.05). Two @entity1 in unilateral group developed with cage related complications, 1 case was cage displacement and 1 case was cage subsidence, while 2 @entity1 in bilateral group developed with complications of no-fusion, and there was no significant differences between two groups (P = 0.58). CONCLUSION: Unilateral pedicle screw fixation is a satisfactory method and can obtain good effects in treating @entity179 in mid-term, however, the indications should be well considered.
