Purpose: To examine the relationship between total fat infiltration (TFI) rate, which quantifies the reduction of muscles around the spine and is an important factor for sarcopenia, and the factors affecting osteoporotic vertebral compression fracture.
Materials and Methods: Patients treated for osteoporotic compression fractures of the lumber spine from January 2012 to December 2016 were analyzed retrospectively. Among them, this study included ninety-eight patients who were 1) diagnosed with osteoporosis with a bone mineral density (BMD) T score of less than 2.5 g/cm2, 2) received vertebroplasty or kyphoplasty for lumbar fractures, 3) involved one segment of the lumbar spine, and 4) were followed-up for more than one year. The TFI rate confirmed by analyzing magnetic resonance imagings with the Image J program was studied. Based on this, the relationship between the TFI of the multifidus and erector spinae muscles and the factors of osteoporosis were analyzed.
Results: The mean TFI of the multifidus and erector spinae was 14.66±10.16. The spine BMD showed a positive correlation with the hip BMD, but a negative correlation with the TFI. A positive correlation was observed between the hip BMD and body mass index. In addition, vitamin D was positively correlated with both the hip and spine BMD but negatively correlated with the TFI rate.
Conclusion: Muscle growth helps treat osteoporosis, and can prevent fractures that occur frequently in osteoporosis patients. Increasing the vitamin intake can also slow the progression of muscle atrophy.
