Ultrasonographic Measurement of Diaphragmatic Thickness in Adolescents With Thoracal Hyperkyphosis

Thoracal hyperkyphosis study form consisting of clinical and radiological measurements of patients aged 10-18 years who applied to the outpatient clinic with chest deformity will be filled in detail.

Patients whose forward bending test and clinical evaluation results are compatible with hyperkyphosis and scoliosis radiographs are requested. Coronal, sagittal balance; coronal and sagittal Cobb angles will be measured from posterior-anterior (PA) and lateral scoliosis radiographs.

"Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help participant healthcare provider diagnose and decide the treatment of certain lung disorders.~The investigators will use handheld spirometry device for measurement. Three measurements will be made. In these three measurements; FEV1(Forced Expiratory Volume In One Second)(L), FEV1 (%predicted), FVC (Forced Vital Capacity) (L), FVC (%predicted), FEV1/FVC (%) and FEV1/FVC (%predicted) will be evaluated. The arithmetic average of the results of these three measurements will be taken."

Diaphragm thickness will be measured in the supine position with a 6-14 Mhz lineer, conventional ultrasound probe (Mindray DC-8, Shenzen Mindray Bio-Medical Electronics CO. LTD.,P.R. China) at the end of inspiration and expiration from the intercostal space on the anterior axillary line. The measurements will be evaluated by making three measurements from the right 8-9. intercostal space where the diaphragm is best visualized. End-expiratory (Forced residual capacity-FRC) (centimeter-cm), end-inspiratory (Total Lung Capacity) (centimeter-cm) and thickening rate (%) (thickness TLC / thickness FRC) will be evaluated three times and the arithmetic average of these three measurements will be taken.
