Abstract

Osteoporosis is a common problem, especially among postmenopausal women. Postmenopausal women with osteoporosis have major risk factors for osteoporotic fractures. The abuse of epidural steroid injections (ESIs) or the misunderstanding of their proper use could cause osteoporotic fractures. Therefore, we aimed to investigate whether ESIs are associated with osteoporotic fractures in postmenopausal women with low back pain and osteoporosis. Furthermore, we aimed to provide evidence on whether ESIs could be used in postmenopausal women with osteoporosis who are at high risk for osteoporotic fractures.We reviewed the medical records of postmenopausal women with osteoporosis but no fractures. A total of 172 postmenopausal women were divided into 2 groups. Group 1 comprised patients receiving medications and Group 2 comprised patients receiving ESIs. All participants received medications for treating osteoporosis. Each patient's age, bone mineral density, body mass index, medical history, and status with respect to smoking, drinking, physical activity, and exercise were obtained using a questionnaire and medical records.The mean total number of ESIs was 6.2, and the mean cumulative administered dose of glucocorticoids (dexamethasone) was 31 mg. The incidences of fractures in the medication and ESI groups were 22% and 24%, respectively, in the thoracolumbar spine, and 2% and 5%, respectively, in the hip joint.There was no significant difference in the incidences of osteoporotic fractures at the thoraco-lumbar spine and hip joint in postmenopausal women with osteoporosis between those who received ESIs (a mean of 6.2 ESIs, a cumulative dexamethasone dose of 31 mg) and those who did not, with both groups taking anti-osteoporotic medications for low back pain. Our data suggest that ESI treatment using a mean of 6.2 ESIs to deliver a maximum cumulative dexamethasone dose of 31 mg could be safely used in postmenopausal women with osteoporosis, without any significant impact on the their risk for osteoporotic fractures.
