Relationship between Bone Mineral Density and Spinal Muscle Area in Magnetic Resonance Imaging
이대영,양재호,기철현,고민석,석경수,김학선,이환모,문성환 대한골대사학회 2015 대한골대사학회지 Vol.22 No.4
Background: Bone mineral density (BMD) is known to have a positive correlation with lean body mass. Several studies have also reported the positive correlation between muscle power and BMD. From this point of view, we hypothesized BMD of lumbar spine to have a positive correlation with muscle mass. Methods: Seventy-nine female patients aged between 60 and 75 years old and who underwent magnetic resonance imaging (MRI) and BMD studies were included. Muscle mass in spine MRI was defined by the sum of the average muscle area of three axial images for each disc level. Lumbosacral muscle is the sum of paraspinal muscle and psoas muscle. Results: In correlation analysis, paraspinal muscle mass showed positive correlation with BMD of lumbar spine. Lumbosacral muscle mass showed positive correlation with BMD of trochanteric area of the femur. However, BMD of other area showed no significant correlation with muscle mass. Conclusions: Therefore, postmenopausal women older than 60 years with a well developed spine muscle mass, have a high BMD.

Quality of Life in Patients with Osteoporotic Vertebral Fractures
윤상필,이승환,기철현,이영태,홍성하,이환모,문성환 대한척추외과학회 2014 Asian Spine Journal Vol.8 No.5
Study Design: A case-control study. Purpose: To examine several dimensions of health-related quality of life (HRQL) in postmenopausal women with osteoporotic vertebral fractures, compared with a control group. Overview of Literature: Osteoporotic vertebral fractures are a major cause of morbidity among postmenopausal women. There have been many reports of a decrease in the quality of life in patients with osteoporotic vertebral fractures. However,few reports have analyzed which dimensions contribute to the decline in quality of life. Methods: One thousand five hundred forty-five postmenopausal women aged 50 years and older from 17 study sites in nationwide hospitals were in enrolled in the study (between April 2008 and January 2009). HRQL was measured using the European Quality of Life 5 Domains (EQ-5D), and visual analogue scale (VAS). Results: The average VAS of the case group was 57.80, and that of the control group was 64.10 (p =0.001). All domains of the EQ- 5D score were significantly worse in the case group (p =0.001). Among the case group, the average VAS of the 559 patients (45%) who were operated on was 56.8, and that of the remaining 680 patients (55%) who were treated conservatively was 58.6 (p =0.135). Among the case group, the averages of each EQ-5D domain of the 559 patients (45%) who were operated on were: 1.87 in mobility, 1.81 in self-care, 1.99 in usual activities, 2.11 in pain, and 1.62 in anxiety or depression. Those of the 680 patients (55%) who were treated conservatively were: 1.72 in mobility, 1.60 in self-care, 1.76 in usual activities, 1.98 in pain, and 1.57 in anxiety or depression. Except for the domain of anxiety or depression, scores for the other domains were all significantly worse in the patients who were operated on (p =0.001). Conclusions: Health related quality of life in the patients with osteoporotic vertebral fractures was significantly worse in both the EQ-5D domains and VAS. Among the osteoporotic vertebral fracture patients, the patients who were operated on had a worse quality of life in EQ-5D.
