- W2390342820 abstract "Objective To evaluate the effects of the position of the retractor on the extent of corpectomy and ventral decompression in minimally invasive posterolateral single-level upper thoracic(T2~5) corpectomy.Methods A total of 60 adult T2~5 CT images were collected,male 30,female 30.The retractor was Abstracted as two parallel lines and simulated operations were performed on one selected image.There were 3 positions each image:a)The retractor passes through the lateral border of the costotransverse articulation and tangent to ipsilateral vertebral body cortex;b)The retractor shifts 3 cm laterally;c)The retractor shifts 5 cm laterally.Compare the extent of corpectomy and ventral decompression between the groups each level and find the statistic difference.Results No significant statistic difference in extent of corpectomy and ventral decompression was noted between males and females at the same position,P0.05;While a significant difference was noted between position 1 and the more lateral positions,P0.01;Position 3 required more rib resection(50.42~62.90 mm),longer working distances(124.35~140.37 mm) and more severe plural disturbing(1.67~5.53 mm).Conclusion The position of the retractor have obvious influence on the extent of corpectomy and ventral decompression in minimally invasive posterolateral single-level upper thoracic(T2~5) corpectomy.It appears optimal the retractor shifts 3 cm laterally during the operation,which made the operation more convenient with less wound and lower incidence of plural and spinal cord injury." @default.
