Ohyama S, et al. - Among outpatients of the spine surgery department, a total of 126 subjects were involved in the study by the researchers in order to explain the association between sarcopenia and spinopelvic parameters. In this study, the prevalence of sarcopenia was 21.4%. Between the sarcopenia and No sarcopenia groups, the spinopelvic parameters except thoracic kyphosis (TK) were did not significantly differ from one another. Between the sarcopenia and No sarcopenia groups, the prevalence of subjects with spinopelvic mismatch was also not significantly distinctive. There was no spinopelvic parameter with a notable variation amongst the 2 groups, in subjects without spinopelvic mismatch. In comparison to those of the No sarcopenia group, the sagittal vertebral axis (SVA) and TK of the sarcopenia group were markedly larger, among patients with a spinopelvic mismatch. In subjects with a spinopelvic mismatch, after adjustment for age, sarcopenia was independently associated with a notable rise in SVA and TK. Hence, in subjects with a spinopelvic mismatch, sarcopenia was concluded to be associated with spinal sagittal imbalance due to insufficient compensation by flattening thoracic kyphosis.
