Abstract

The mean operative time for monosegment pedicle instrumentation (MSPI) was 93 ± 20 minutes.

In the MSPI group, intraoperative blood loss averaged 184 ± 64 ml, while the short segment pedicle instrumentation (SSPI) group had an average of 203 ± 88 ml.
The visual analogue scale (VAS) score improved from 7.6 ± 1.5 before operation to 1.5 ± 0.9 at the latest follow-up in the MSPI group.
The vertebral kyphotic (VK) angle in the MSPI group decreased from 17° ± 10° before surgery to 10° ± 7° at the latest follow-up.
Both MSPI and SSPI groups showed significant reductions in VAS score and VK angle at one week after surgery compared to preoperative values.
No adjacent segment degeneration was reported in the MSPI group, while one case was observed in the SSPI group within 36 months post-operation.

OBJECTIVE: To investigate the safety and therapeutic effects of monosegment pedicle instrumentation in treating incomplete thoracolumbar burst fracture.

METHODS: A retrospective analysis was conducted on 56 inpatients with incomplete thoracolumbar burst fracture (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, blood loss, visual analogue scale (VAS) 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 blood loss 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; VAS 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 adjacent segment degeneration was found. In the group of SSPI, the operative time was (102 ± 30) min; the intraoperative blood loss 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; VAS 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 adjacent segment degeneration was found in 36 months after operation. There were no significantly statistical differences between two groups in operative time, blood loss, VAS score and VK angle before and after surgery (P > 0.05). The VAS 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 incomplete thoracolumbar burst fracture is effective and safe. The operative blood loss, the mean operative time, the improvement of VAS score and the VK angle in group MSPI are equal to those in group SSPI.
