the relationship between pectus deformities and spinal pathologies

Conditions: Pectus Deformity of Chest; Spinal Deformity

Summary: pectus deformities are common anterior chest wall pathologies. pectus excavatum is the most common chest deformity with an incidence of 0.1-0.3%. although the incidence of adolescent idiopathic scoliosis (ais) is 0.2-3% in the community, some studies show that this rate rises to 17.61-25.58% when it is associated with pectus deformity. while the pectus excavatum rotates the heart to the left with its ribs and cartilages, it pushes the thoracic vertebra to the right side with the internal counterforce created by the heart, which has been shown to push the spine to the right with an asymmetric horizontal force in scoliosis patients with pectus deformity. based on this, in study, investigators aimed to determine whether there is any relationship between pectus deformities and spinal pathologies, and if there is a relationship, with which pathology it is most common, whether the type of scoliosis seen in pectus deformities with a prominent scoliosis prevalence is a pectus-specific curve, and whether this curve seen in scoliosis is associated with pectus. to determine whether there is a footprint or not.

the study was planned as a prospective cross-sectional study. pectus study forms consisting of clinical and radiological measurements of the patients aged 3-18 years who applied to the outpatient clinic with chest deformity will be filled in in detail, and the adams test (forward bending test) (+) will be measured by bunnell scoliometer (scoliosis assessment tool) and atr (angle of trunk rotation- trunk rotation) measurements. if atr measurement is above 7 degrees on bunnell scoliometer, patients who meet the inclusion criteria will be included in the study by filling in the informed consent form and a scoliosis radiograph will be requested (independent of investigators' study, it is necessary to withdraw it in line with the 2016 recommendations of the international scientific society for scoliosis orthopedic and rehabilitation treatment (sosort).) coronal, sagittal balance, coronal and sagittal cobb angles will be measured from the scoliosis radiograph taken from the posterior-anterior (pa) (posterior-anterior) and lateral (side) films. their relationship with chest deformities will be evaluated. all measurements will be made and recorded by two independent investigators as a result of the analysis, when the power is targeted as 95% and the error amount as 0.05, the minimum sample size required for investigators to find a significant difference between the means was determined as 36. investigators formed a sample group of 40 people for our study, together with the fact that groups of 36 people were sufficient in terms of providing 95% power. kappa statistical analysis will be used to determine intraobserver and interobserver variations.

Eligibility criteria:
inclusion criteria: * being diagnosed with pectus deformity * be between 3-18 years old exclusion criteria: * adult type scoliosis * congenital scoliosis * neuromuscular scoliosis * syndromic scoliosis * infantile idiopathic scoliosis * having surgery to the chest wall or spine * people with connective tissue disease will not be included in the study.
