Evaluation of the Effect of Halo Gravity Traction on Lung Volume in Advanced and Severe Kyphoscoliosis Patients in Chest Radiography

Abstract

Aim: To evaluate the effect of preoperative halo gravity traction on lung volume in patients with advanced and rigid kyphoscoliosis using planimetric measurements from chest radiography. Method: Ten patients with a mean age of 20.5±0.9 with a diagnosis of severe and severe kyphoscoliosis who underwent halo gravity traction between 2019 and 2021 were included in our study. Direct chest radiographs taken before and after traction were analyzed retrospectively. In order to evaluate the effectiveness of traction, planimetric evaluations were made on radiographs. Results: In the evaluation of radiological parameters, mean thoracic coronal cobb angle, lumbar cobb angle, thoracic kyphosis angle, lumbar lordosis angle, C1-S1 distance and lung volume before and after the procedure were 96.670°±8.4535°, 88,090°±4.5989°, 37.020°±11.5893°, 38.540°±11.1269°, 73.150°±7.0412°, 65.590°±7.3927°, 59.100°±9.5467°, 55.100°±9.0238°, It was 371.590mm± 64.2410mm, 408.330 mm±80.8229 mm and 967.730 mm3±318.404 mm3, 1155.180mm3±332.868 mm3. The decrease in thoracic kyphosis, lumbar lordosis, thoracic cobb and lumbar cobb angles and the increase in lung volume and distance between C1-S1 were statistically significant (p<0.05). Conclusion: Traction application is a safe method for deformities. It is effective in correcting sagittal and coronal curvatures. It is a method that is effective in pulmonary functions as well as increasing the lung volume radiologically.
