Abstract
BACKGROUND:Currently, many scholars have made a large amount of studies on applied anatomy of adult Chinese lumbar isthmus at L5, but study results are diverse. Moreover, parameters were not systematic or complete. No control studies concerned the clinical applied anatomy and Micro CT imaging anatomy on adult Chinese lumbar isthmus at L5. <br> OBJECTIVE:To observe and measure Micro CT imaging anatomy and applied anatomy on adult Chinese lumbar isthmus at L5 so as to provide morphological evidence for vulnerability of the adult Chinese lumbar isthmus at L 5 . <br> METHODS:A total of 60 dried intact adult Chinese lumbar isthmus at L5 specimens were randomly obtained from the Laboratory of Regional Anatomy, Chengdu Medical Col ege. Relevant data of lumbar isthmus at L5 were measured using vernier caliper. Three-dimensional bone architecture of lumbar isthmus at L5 was analyzed using Micro CT three-dimensional reconstruction system. Parameters of Micro CT imaging anatomy corresponding to the applied anatomy of left and right lumbar isthmus at L5 were measured. <br> RESULTS AND CONCLUSION:Measurement on adult Chinese lumbar isthmus at L5 was performed: ① The thicknesses of upper border of left and right isthmus were respectively (4.27±0.99) mm and (4.25±0.98) mm. ② The thicknesses of lower border of left and right isthmus were respectively (7.31±1.23) mm and (7.29±1.25) mm. ③ The thicknesses of inner border of left and right isthmus were respectively (6.61±0.33) mm and (6.59±0.36) mm. ④ The thicknesses of exterior border of left and right isthmus were respectively (8.65±0.27) mm and (8.59±0.33) mm. ⑤ The distances of upper and lower borders of the left and right isthmus were respectively (11.10±3.14) mm and (11.07±3.11) mm.⑥ The lengths of upper border of the left and right isthmus were respectively (8.37±0.99) mm and (8.40±0.96) mm. ⑦The lengths of lower border of the left and right isthmus were respectively (4.71±0.71) mm and (4.73±0.62) mm. ⑧ The lengths of inner border of the left and right isthmus were respectively (13.01±1.38) mm and (13.04±1.36) mm. ⑨ The lengths of exterior border of the left and right isthmus were respectively (10.75±1.11) mm and (10.78±1.06) mm. No significant difference in the three-dimensional values of the left and right isthmus at L5 measured by vernier caliper and Micro CT was detected. Results verified that the measure values measured by vernier caliper and Micro CT on adult Chinese lumbar isthmus at L5 were uniform, and no significant difference was detectable between the left and right sides. Micro CT provides precise reference evidence for the vulnerability of L 5 vertebra in the clinic.关键词
