Abstract
We conducted a randomized control study to compare the effects of pain, QOL, bone metabolism and fracture healing by administering bisphosphonate (BP) or weekly teriparatide preparation (W-TPTD) to 43 patients (5 males and 38 females) with fresh spinal vertebral compression fractures for osteoporosis. The patients were aged between 61 and 93 years old (mean 78.1 years). In principle, a MRI was used for any diagnosis of new vertebral fractures. From this study, lumbar spine bone mineral density (BMD), after 24 weeks of administration, showed a significant increase (p < 0.05) in both the BP group (mean 5.3%) and in the W-TPTD group (mean 4.9%). The W-TPTD group showed a better Roland-Morris disability Questionnaire (RDQ) improvement throughout the whole period of the study compared with the BP group, the difference was statistically significant after 24 weeks of administration (p < 0.05). The EuroQol 5 dimensions (EQ-5D) and visual analogue scale (VAS) score significantly improved over time in both groups (p < 0.05). The fracture-healing rate was observed in 45% of the BP group and 73% of the W-TPTD group at Week 12, and a statistically significant higher fracture-healing rate was obtained in the W-TPTD group compared to the BP group (p < 0.05). The mean time of fracture-healing was 3.9 months for the BP group and 2.8 months in the W-TPTD group. Statistically significant faster fracture-healing was observed in the W-TPTD group (p < 0.05). At Week 12 and Week 24, P1NP was significantly higher in the W-TPTD group compared to that of the BP group (p < 0.05). TRACP-5b showed no major fluctuations during the study period in either group. These results suggest that W-TPTD may promote better fracture healing of any new osteoporotic vertebral compression fractures compared with a BP.
