Abstract:

Objective

To evaluate the effect of growing rod technique on chest volume in the treatment of congenital scoliosis based on the radiographic images.

Methods

From July 2010 to July2016, 23 patients with congenital scoliosis underwent surgical treatment by growing rod technique in our center. Radiographic parameters associated with chest volume and thoracic spine were measured on anteroposterior and lateral standing radiograph of the whole spine, including the Cobb angle of

main thoracic curve, thoracic kyphosisTK, T1-12 height, thoracic anteroposterior diameter, thoracic sagittal longitudinal diameter, maximal chest width, Campbells space available for lung ratioSAL. The data at each follow-up time point were recorded and statistically analyzed.

Results

The Cobb angle of main thoracic curve, TK, T1-12 height, chest anteroposterior diameter, sagittal longitudinal diameter, maximal chest width and SAL after each of distraction procedures and at the latest follow-up, increased significantly compared with those preoperatively P<0.05. In term of variations of these parameters from the preoperative to the final follow up, the Cobb angle proved positive correlations with the T1-12 heightr=0.584, P0.05, the chest sagittal heightr=0.594, P0.05and the SALr=0.693, P0.05. Curved line of the chest volume parameter varied from rapid alteration to flat as distraction times increased.

Conclusions

The application of growing rod technique for the treatment in congenital scoliosis is not only correcting the spinal deformity and preserving spine growth potentials, but also adjusting unbalanced heights of asymmetrical skeletal chest and restoring chest volume, however, above effects tend to decline with the increase of times of distraction procedures.
