OBJECTIVE: To investigate the safety and therapeutic effects of monosegment pedicle instrumentation in treating @entity174 . METHODS: A retrospective analysis was conducted on 56 inpatients with @entity174 (AO classification: A3.1 and A3.2) from April 2005 to January 2010. There were 28 cases were fixed with monosegment pedicle instrumentation (MSPI), 28 cases were fixed with short segment pedicle instrumentation (SSPI). The operative time, @entity190 , @entity227 ( @entity227 ) and vertebral kyphotic angle (VK) before and after surgery were evaluated. RESULTS: In the group of MSPI, the mean operative time was (93    20) min; the intraoperative @entity190 was (184    64) ml; the VK angle was 17      10   before operation, 7      7   at one week after operation, and 10      7   at latest follow-up; @entity227 score was 7.6    1.5 before operation, 2.4    0.8 at one week after operation, and 1.5    0.9 at latest follow-up; no @entity528 was found. In the group of SSPI, the operative time was (102    30) min; the intraoperative @entity190 was (203    88) ml; the VK angle was 17      9   before operation, 7      7   at one week after operation, and 8      5   at latest follow-up; @entity227 score was 6.8    1.3 before operation, 3.1    0.5 at one week after operation, and 1.2    0.7 at latest follow-up. One case of @entity528 was found in 36 months after operation. There were no significantly statistical differences between two groups in operative time, @entity190 , @entity227 score and VK angle before and after surgery (P > 0.05). The @entity227 score and VK angle at one week after surgery and latest follow-up all decreased obviously than preoperative ones in both groups (P < 0.05). CONCLUSIONS: MSPI for @entity174 is effective and safe. The operative @entity190 , the mean operative time, the improvement of @entity227 score and the VK angle in group MSPI are equal to those in group SSPI.
