Background:

• Bone diseases, including osteosarcoma and metastatic bone cancer, present significant challenges due to treatment ineffectiveness, poor patient compliance, and adverse side effects.
• Current therapeutic strategies often fall short in managing skeletal-related disorders that lead to mobility limitations and mortality.

Purpose of the Study:

• To review current therapies for bone diseases, with a focus on novel discoveries in targeted drug delivery systems.
• To explore the potential of nanotechnology in enhancing bone regeneration and overcoming limitations of existing treatments.

Main Methods:

• Review of current literature on bone disease treatments and nanotechnology applications.
• Analysis of various nanoscale materials (polymers, ceramics, metals, etc.) and nanosystems (scaffolds, nanoparticles, hydrogels) for bone targeting.
• Focus on targeted delivery systems for specific drug release kinetics.

Main Results:

• Nanotechnology presents a promising strategy for targeted drug release and improved bone regeneration.
• Scaffolds, nanoparticles (NPs), cements, and hydrogels are identified as advantageous nanosystems for bone disease applications.
• Surface modification of nanomaterials is often required for optimal performance.

Conclusions:

• Nanotechnology holds significant potential for advancing the treatment of bone diseases and promoting bone regeneration.
