Hydrogel-based delivery system applied in the local anti-osteoporotic bone defects

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Skeletal Biology

Background:

• Osteoporosis is a prevalent skeletal disease causing bone loss and deterioration.
• Current systemic osteoporosis treatments have limitations in bioavailability and side effects.
• Combined local and systemic therapies may offer superior therapeutic benefits.

Purpose of the Study:

• To review the advantages of hydrogels for local drug delivery in osteoporosis treatment.
• To discuss various types of hydrogels (nature-based, synthetic, composite) suitable for this application.
• To explore functional adjuvants (drugs and cells) loaded within hydrogels for bone regeneration.

Main Methods:

• Literature review of hydrogel properties and applications in bone tissue engineering.
• Analysis of hydrogel characteristics such as biocompatibility, mechanical properties, and degradation rate.
• Examination of therapeutic agents (drugs and cells) for osteoclast inhibition and osteoblast promotion.

Main Results:

• Hydrogels demonstrate excellent potential as carriers for local therapeutic treatments in bone defects.
• Various hydrogel formulations offer tunable properties for controlled drug release and tissue integration.
• Functional adjuvants, including osteogenic cells and drugs, can be effectively incorporated into hydrogels.

Conclusions:

• Hydrogel-based delivery systems represent a significant advancement for localized osteoporosis therapy.
• Careful selection of hydrogel materials and therapeutic adjuvants is crucial for treatment success.
• This review provides a reference for future research and clinical translation of hydrogel therapies for osteoporosis.
