AIM Sarcopenia-related falls and fractures are becoming an emerging problem as a result of rapid aging worldwide. We aimed to investigate the prevalence of sarcopenia by estimating the muscle mass of the arms and legs of patients with and without hip fracture. METHODS This cross-sectional study examined 357 patients immediately after a hip fracture (the(More)
Two case-control studies were designed to investigate the contribution of the geometry and bone mineral density (BMD) of the proximal femur to bone strength in Japanese elderly women. We also investigated whether clinical CT is useful to assess the risk of hip fracture. Subjects in the neck fracture study included 20 Japanese women with neck fracture (age:(More)
STUDY DESIGN This was a prospective clinical comparative study of surgical outcomes for patients with cervical spondylotic myelopathy (CSM). OBJECTIVE The purpose of this study was to compare the surgical outcomes between nonelderly and elderly patients with CSM who underwent laminoplasty. SUMMARY OF BACKGROUND DATA Age at the time of surgery influences(More)
Sarcopenia, an aging-induced generalized decrease in muscle mass, strength, and function, is known to affect elderly individuals by decreasing mobile function and increasing frailty and imbalance that lead to falls and fragile fractures. Sarcopenia is a known risk factor for osteoporotic fractures, infections, and early death in some specific situations.(More)
STUDY DESIGN A large-scale analysis of radiographical results of patients with cervical spondylotic myelopathy and a review of the literature. OBJECTIVE To identify changes in sagittal alignment and range of motion (ROM) after cervical laminoplasty. SUMMARY OF BACKGROUND DATA Cervical laminoplasty is an effective procedure for decompressing multilevel(More)
STUDY DESIGN A retrospective single-center study. OBJECTIVE To investigate the prevalence of symptoms before and after surgery in a large series of patients with cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA No study has elucidated the epidemiological data regarding the prevalence of pre- and postoperative symptoms in patients with(More)
Sarcopenia-related falls and fractures among women with osteoporosis are becoming an emerging problem because of rapid aging worldwide. We aimed to investigate the association between sarcopenia, given by the muscle mass of the arms and legs, and osteoporotic vertebral fracture (OVF) among female patients. This cross-sectional study examined 216 women with(More)
STUDY DESIGN This is a prospective study on surgical outcomes of double-door laminoplasty in patients with cervical spondylotic myelopathy (CSM). OBJECTIVE The purpose of this study was to report the efficacy and safety of modified double-door laminoplasty in a large series of patients with CSM. SUMMARY OF BACKGROUND DATA Laminoplasty is an established(More)
STUDY DESIGN A large-scale retrospective study of analysis of postoperative residual symptom in patients with cervical spondylotic myelopathy (CSM). OBJECTIVE The purpose of this study was to investigate which symptom remains postoperatively in a large series of patients with CSM. SUMMARY OF BACKGROUND DATA CSM is an increasingly common neurological(More)
OBJECTIVE Little is known about the progression of spinal schwannomas. The aim of this study was to determine the natural progression of spinal schwannomas and establish the risk of tumor growth. METHODS This study retrospectively analyzed data from 23 patients (12 men and 11 women, 40-89 years old) with schwannomas detected by MRI. The mean follow-up(More)
