Investigation of scoliosis type and spino-pelvic parameters according to menstrual pain severity in adolescent idiopathic scoliosis.

This study was planned to investigate the scoliosis type and spino-pelvic parameters according to the severity of menstrual pain in subjects diagnosed with adolescent idiopathic scoliosis (AIS). The study included 114 subjects with a mean age of 15,8 ± 2,7 years, antero-posterior and lateral radiographs, and diagnosed with AIS. The menstrual pain of the subjects was evaluated with Visual Analogue Scale and then the subjects were divided into 3 groups according to their mean menstrual pain severity; 0-3 cm "none-mild pain group" (n: 39), 3,1-7 cm "moderate pain group"(n: 43) and 7,1-10 cm: "severe pain group" (n: 32). The descriptive characteristics (demographic and physical characteristics, brace wear, anxiety and depression level), scoliosis severity (Cobb angle), scoliosis type (number of curves, primary curve region) and spino-pelvic parameters (thoracic kyphosis, lumbar lordosis, pelvic incidence, pelvic tilt, sakral slop, degree of pelvic obliquity, pelvic shift, and pelvic axial rotation) of all subjects were measured. There was a significant difference between the groups in terms of age, educational status and degree of pelvic obliquity (p <0,05), but there were no difference in terms of other descriptive characteristics, scoliosis severity, scoliosis type and other spinopelvic parameters. (p> 0,05). The degree of pelvic obliquity was greater in the severe pain group. According to the results of our study, it can be said that the severity of menstrual pain increases as the degree of pelvic obliquity increases in patients diagnosed with AIS. Further studies with large samples should be planned to evaluate the severity and type of scoliosis and spinopelvic parameters by methods that allow standard and multidimensional analysis and to examine the relationship between these parameters and menstrual pain. Key words: Adolescent idiopathic scoliosis, Cobb, menstrual pain, pelvic obliquity, spinopelvic parameter.
