Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Any spinal deformity, especially one that affects the thoracic spine, can affect lung function. If left untreated, the curves may distort over time as skeletal growth accelerates. In some patients, this can lead to restrictive or obstructive lung disease and, rarely, death as a result of cor pulmonale.
The alignment of the skeletal system in the chest and its harmony with the compliance of the chest wall are related to respiratory function; Thoracic kyphosis and the resulting changes in the rib cage lead to a decrease in lung capacity. The diaphragm is the main respiratory muscle, and diaphragm contraction is associated with respiratory functions. In recent years, ultrasonography (USG) has gained increasing utility for visualizing the diaphragm and assessing its function, with several advantages.
Based on this, the investigators aimed to measure the diaphragmatic thickness in adolescents with increased thoracal kyphosis (thoracal hyperkyphosis) deformities, to show whether there is any relationship between increased kyphosis deformity and diaphragmatic thickness, and to show whether there is any change in diaphragmatic thickness before or after the treatment for kyphosis.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Patients aged 10-18 years who were diagnosed with thoracal hyperkyphosis deformity
Thoracal Hyperkyphosis study form consisting of clinical and radiological measurements of patients aged 10-18 years who were diagnosed with thoracal hyperkyphosis deformity and applied to the scoliosis outpatient clinicwill be filled in detail.
Thoracal hyperkyphosis study form
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.
Scoliosis graphy
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 test
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.
Ultrasonographic Measurement
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.
