Table 1 Radiological parameters evaluated at the admission, postoperation, and final observation ��LSA showed no significant correlation with either sex or age (p=0.23, 0.59, respectively). Also, no significant correlations were observed between ��LSA and the level of injury or the AO classification (p=0.87 and 0.81, respectively). However, a strong correlation was observed between ��LSA and the load sharing classification score (p=0.0001; Spearman's rho=0.64) (Fig. 2).

Table 2 Radiological outcomes of short segment posterior instrumentation and fusion for 31 patients Table 3 shows the correlation between the radiological outcome and the load sharing classification score. A load sharing score of more than 7 points tended to demonstrate the failed [http://www.selleckchem.com/products/dorsomorphin-2hcl.html check details] radiological outcome with an odds ratio of 12.67. Table 3 The correlation between the radiological outcome and the load sharing classification score Discussion In the early era of spinal instrumentation, posterior approach alone was proven to be inadequate for maintaining stability of the injured spine and yielded poor results in both the anatomical and functional aspects [8,11,14,15]. However, with the development of metallurgic technology and instrumentation design, pedicle screws nowadays seem to obviate the need for anterior approach. Long segment instrumentation is strong enough to stabilize the spine. However, the fused spine becomes less flexible and more susceptible to low back pain. Therefore, short segment posterior instrumentation is thought to be a better option able to stabilize the fractured vertebra efficiently. It is also a simple technique and allows for more segmental motion of the spine. Age, osteoporosis and degree of comminution of the vertebral body are risk factors for poor [http://www.selleckchem.com/products/Staurosporine.html find more] surgical outcomes [9,10]. In our study, kyphotic deformity was corrected to a considerable extent with posterior instrumentation and indirect reduction. However, the correction of kyphotic deformity which was evaluated by LSA and RSA was gradually lost during the follow up period. Although the indirect reduction by ligamentotaxis had a positive effect on the wedging deformity of the fractured vertebra, preservation of the correction might be difficult. The large bone defect created inside the fractured vertebra after height restoration had been speculated to be the most important cause of that correction loss.
