  • RELIABILITY RESEARCH OF MULTI-PLANNAR REFORMATION OF MULTI-SPIRAL COMPUTERIZED TOMOGRAPHY IN MEASURING KYPHOSIS ANGLE AFTER THORACOLUMBAR FRACTURE

    Objective To study the feasibil ity and rel iabil ity of the multi-plannar reformation (MPR) of multispiral CT (MSCT) in measuring the kyphosis angle (KA) after thoracolumbar fracture. Methods From December 2007 to December 2009, 45 thoracolumbar fracture patients who underwent computed radiology (CR) and MSCT were recruited. There were 32 males and 13 females with a mean age of 48 years (range, 24-63 years), including 36 simple compression fractures and 9 burst fractures. The fracture locations were T11 in 6 cases , T12 in 11 cases, L1 in 20 cases, and L2 in 8 cases. Fracture was caused by trafffic accident in 25 cases, by fall ing from height in 12 cases, and by others in 8 cases. The imaging examination was performed after 2 hours to 7 days of injury in 22 cases and after more than 7 days in 23 cases. The KA was measured on the lateral X-ray films of CR and MPR by two observers, then the measurements were done again after three weeks. The data were statistically analyzed. Results The average KA values on CR by two observers were (20.75 ± 8.31)° and (22.49 ± 9.07)°, respectively; showing significant difference (P lt; 0.05), and the correlation was good (r=0.882, P lt; 0.05). The average KA values on MPR by two observers were (16.65 ± 8.62)° and (17.08 ± 7.88)°, respectively, showing no significant difference (P gt; 0.05), the correlation was excellent (r=0.976, P lt; 0.05). The average KA values on CR and MPR were (21.61 ± 8.43)° and (16.87 ± 8.20)°, respectively; showing significant difference (P lt; 0.05), the correlation was good (r=0.852, P lt; 0.05). Conclusion It is more feasible and rel iable in measuring the KA on MRP of MSCT than CR, but the value is larger on CR.
