Midsagittal computed tomography (CT) images were analyzed by ImageJ to assess the intravertebral bone formation (mineralized bone) by calculating the ratio of area of intravertebral mineralized bone (AIMB) to the area of fractured vertebral body (AFVB). The changes in radiological parameters of the fractured vertebral body including kyphosis angle (KA), anterior and posterior border heights (ABH and PBH) and spinal canal diameter (SCD), bone turnover biomarkers (BTMs), and bone mineral density (BMD) were analyzed to evaluate the therapeutic effect.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At month 12, the ratio of AIMB to AFVB was significantly greater in teriparatide group (54.28%\u2009\u00b1\u200915.30%) than in alendronate group (35.57%\u2009\u00b1\u200917.61%) (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Sagittal CT substantiated the formation of bone bridge in 16 patients in teriparatide group. No bone bridge was detected in alendronate group. The KA was significantly smaller and the ABH, PBH, and SCD was greater in teriparatide group than in alendronate group (all <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The KA increments were significantly smaller in teriparatide group (3.98\u00b0 \u00b1\u20091.30\u00b0) than in alendronate group (11.43\u00b0\u2009\u00b1\u20093.73\u00b0) (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The ABH and PBH decrement were significantly lower in teriparatide group (11.96%\u2009\u00b1\u20091.93% and 2.80%\u2009\u00b1\u20092.52%) than in alendronate group (37.04%\u2009\u00b1\u20098.00% and 19.50%\u2009\u00b1\u20098.22%) (both <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The BTMs and BMD were significantly greater in the teriparatide group than in the alendronate group.
