The relationship between the expression of TN and the efficiency of posterior spinal V osteotomy in patients with traumatic kyphosis

Background: This study was conducted with the aim to investigate the relationship between Tetranectin (TN) and efficiency of posterior spinal V osteotomy in patients with traumatic kyphosis. Methods: Ninety-two patients with traumatic kyphosis admitted in our hospital from February 2014 to June 2016 were included whose serum TN levels were examined by ELISA. Using the mean level of TN as cut-off value, patients were classified into TN high level group (group I) and TN low level group (group II). The observation indexes, including operation time, intra-operational loss of blood, Cobb angle, postoperative complications and recurrence rate of kyphosis within post-operational 6 months were recorded for comparison. Results: TN level was significantly higher in group I [(6.19 +/- 0.33) mu mol/L] than that in group II [(5.29 +/- 0.34) mu mol/L] (P<.05). There was no significant difference in average age, sex, lesion site and average time from injury to operation between the two groups (all P>0.05). Compared to group II, operation time in group I was significantly shortened (5.02 +/- 1.15 VS 4.58 +/- 0.53, P=.023), the intraoperational loss of blood decreased (2418.56 +/- 362.06 VS 2235.84 +/- 325.63, P=.013), post-operational Cobb angle decreased (11.10 +/- 1.31 VS 6.93 +/- 1.04, P=.000), and the incidence of postoperative complications (nail-breaking, rod-breaking and looseness) and recurrence rate decreased (18.8% VS 4.5%, P=.036; 10.4% VS 0.0%, P=.028). Conclusion: Serum TN level is proved to be related to the efficiency of posterior spinal V osteotomy in patients with traumatic kyphosis, and may serve as a possible indicator for clinical treatment.
