Outline of Final Research Achievements

We investigated the prevalence of sarcopenia and the influences on treatment outcomes in the elderly patients with spinal representative disease such as cervical spondylotic myelopathy (CSM) and lumbar spinal stenosis (LSS). Sarcopenia was evaluated using whole-body dual-energy x-ray absorptiometry (DXA) before and after surgical treatment. The prevalence of sarcopenia was 28.1% in CSM and 25.1% in LSS, respectively. Cross-sectional evaluation of muscle mass was associated with the treatment of spinal disease, thus sarcopenia seems to be a valuable investigative tool for elderly locomotive disorders and therapeutic approach targeted to skeletal muscle should be promising to improve surgical outcomes. Longitudinal evaluation of muscle mass, namely, actual aging change in skeletal muscle mass may be open up a new possibilities for the definition of sarcopenia, because longitudinal decline in muscle mass was associated with the surgical results in patients with LSS either.
