Summary
Antiresorptive therapy improves bone strength in osteoporosis by enhancing mineralization. However, long-term use can harm bone quality; intermittent therapy may be a better option.
Area of Science:
- Bone biology
- Pharmacology
- Orthopedics
Context:
- Osteoporosis is characterized by high bone turnover.
- Antiresorptive medications are a common treatment for osteoporosis.
- Long-term effects of these therapies on bone quality require careful consideration.
Purpose:
- To evaluate the impact of antiresorptive therapy on bone mineralization and strength.
- To investigate the consequences of long-term antiresorber use on bone microcrack repair and remodeling.
- To propose an optimized therapeutic regimen for osteoporosis management.
Summary:
- Antiresorptive therapy enhances bone stiffness and toughness by increasing the mean degree of mineralization through prolonged secondary mineralization.
- Sustained use of antiresorbers leads to hypermineralized bone, impairing microcrack repair due to inhibited bone remodeling.
- Intermittent antiresorber administration is suggested to mitigate bone quality deterioration.
Impact:
- Findings suggest that intermittent antiresorptive therapy may preserve bone quality while maintaining therapeutic benefits.
- This approach could optimize osteoporosis treatment, balancing efficacy with the prevention of adverse skeletal effects.
- Recommendations guide clinical practice towards safer, long-term osteoporosis management strategies.
