Abstract Objective To investigate the clinical effect of laminectomy decompression and poking reduction combined with vertebral bone graft for thoracolumbar fracture with spinal canal encroachment. Methods All of 63 patients who had thoracolumbar fracture in AO-A type accepted operation in the period of August 2010 to May 2013. They were divided into two groups based on the surgical procedure. The group A (30 cases) was accepted laminectomy decompression and poking reduction combined with vertebral bone graft. The group B (33 cases) was accepted short-segment fixation and laminectomy decompression. The operative time, intraoperative blood loss, vertebral body height, Cobb angle, and Oswestry disability index (ODI) before and one week after operation, and final follow-up were recorded and analyzed. Results All the operations were completed successfully, and all incisions were healed in phase I. The operation time and intraoperative blood loss in the group B were less than those in the group A (P < 0.05). One week after operation, the vertebral body height, local Cobb angle of the two groups were better than those before operation, and the vertebral body height, local Cobb angle in the group A were better than those in the group B (P < 0.05). At final follow-up time, in the group B, the vertebral body height was lost, and local Cobb angle was increased (P < 0.05), while group A was sustained well (P ＞ 0.05). Conclusion Laminectomy decompression and poking reduction combined with vertebral bone graft will, but can maintain the height of the vertebral body well and avoid the shell-like vertebral body occurred, although it will increase the operation time.
