Study Design: Retrospective study. Purpose: To evaluate the radiological outcome of the surgical treatment of thoracolumbar burst fractures by using short segment posterior instrumentation (SSPI) and fusion. Overview of Literature: The optimal surgical treatment of thoracolumbar burst fractures remains a matter of debate. SSPI is one of a number of possible choices, yet some studies have revealed high rates of poor radiological outcome for this SSPI. Methods: Patients treated using the short segment instrumentation and fusion technique at the Spinal Injuries Center (Iizuka, Fukuoka, Japan) from January 1, 2006 to July 31, 2012 were selected for this study. Radiographic parameters such as local sagittal angle, regional sagittal angle, disc angle, anterior or posterior height of the vertebral body at admission, postoperation and final observation were collected for radiological outcome evaluation. Results: There were 31 patients who met the inclusion criteria with a mean follow-up duration of 22.7 months (range, 12–48 months). The mean age of this group was 47.9 years (range, 15–77 years). The mean local sagittal angles at the time of admission, post-operation and final observation were 13.1°, 7.8° and 14.8°, respectively. There were 71% good cases and 29% poor cases based on our criteria for the radiological outcome evaluation. The correction loss has a strong correlation with the load sharing classification score (Spearman rho=0.64, p <0.001). Conclusions: The loss of kyphotic correction following the surgical treatment of thoracolumbar burst fracture by short segment instrumentation is common and has a close correlation with the degree of comminution of the vertebral body. Patients with high load sharing scores are more susceptible to correction loss and postoperative kyphotic deformity than those with low scores.

In this paper, the efficiency and the inhibition mechanisms of cobalt salts (cobalt nitrate and cobalt-exchangesilica Co/Si) for the corrosion protection of AA2024 were investigated in a neutral aqueous solution byusing the electrochemical impedance spectroscopy (EIS) and polarization curves. The experimental measurementssuggest that cobalt cation plays a role as a cathodic inhibitor. The efficiency of cobalt cation was importantat the concentration range from 0.001 to 0.01 M. The formation of precipitates of oxides/hydroxides ofcobalt on the surface at low inhibitor concentration was confirmed by the Scanning Electron Microscopy/EnergyDispersive X-Ray Spectroscopy (SEM/EDS) analysis. EIS measurements were also conducted for the AA2024surface covered by water-based epoxy coating comprising Co/Si salt. The results obtained from exposurein the electrolyte demonstrated the improvement of the barrier and inhibition properties of the coating exposedin the electrolyte solution for a lengthy time. The SEM/EDS analysis in artificial scribes of the coatingafter salt spray testing revealed the release of cobalt cations in the coating defect to induce the barrierlayer on the exposed AA2024 substrate.
