Abstract

Selective estrogen receptor modulators (SERMs) are drugs used to treat osteoporosis. Selective estrogen receptor modulators improve bone mineral density and bone mechanical strength. However, there is a lack of data on the effect of SERMs on osteoporotic spinal fusion. This study aimed to investigate whether treatment with a SERM enhances spinal fusion in an ovariectomized (OVX) rat model. An in vivo animal study was carried out. Female Sprague Dawley rats (n=90) were OVX or sham-operated, and randomized into three groups: control (sham-operated+fusion procedure+saline administration), OVX (OVX+fusion procedure+saline administration), and SERM (OVX+fusion procedure+administration of SERM). Eight weeks after OVX, a bilateral lumbar spinal fusion procedure was performed using autologous iliac bone. In each group, gene expression was evaluated at 2, 4, and 8 weeks after the fusion procedure, histologic analysis was performed at 4 and 8 weeks after the procedure, and bone parameters were measured by micro-computed tomography at 2 days, 4 weeks, and 8 weeks after the procedure. Bone mineral density and trabecular quality of the vertebral body were significantly higher in the SERM group compared with the OVX group 16 weeks after OVX....Continue Reading
