Abstract:
Methods:This study involved 104 asymptomatic adults (females 62 [59.6%]) aged 18–50 years. Whole-spine standing lateral radiographs were obtained, and the pelvic, lumbar, thoracic, cervicothoracic, and cervical parameters were studied. Pearson’s correlation coefficient was used to assess correlations, with a significance threshold of p<0.05.
Results:The mean age of participants was 38.27±9.93 years. The pelvic incidence (PI) significantly correlated with C7 slope (r=−0.212, p=0.05). The pelvic tilt (PT) exhibited significant correlations with T1 slope−CL mismatch (r=−0.229, p=0.05) and C2 slope (r=−0.202, p=0.05). Furthermore, PI–LL mismatch showed a significant correlation with TIA (r=−0.197, p=0.05), T1 slope (r=−0.228, p=0.05), and C7 slope (r=−0.251, p=0.05).
Conclusions:This study reveals a significant correlation between cervical and spinopelvic parameters, emphasizing the interconnectedness of pelvic, lumbar, thoracic, and cervical spine parameters.
