What Is It?

Percutaneous osteosynthesis is an advanced image-guided technique that stabilizes bone using screws, pins, or fixation systems inserted through small skin incisions.

It is particularly useful in long bones and complex skeletal structures affected by tumors or fractures.

Indications

• Impending or established pathological fractures

• Bone metastases in load-bearing regions (pelvis, femur, humerus)

• Mechanical instability not adequately managed with cement alone

• Complex or multi-site skeletal involvement

Role in Interventional Oncology

Percutaneous osteosynthesis is often combined with:

• Cementoplasty

• Tumor ablation

to provide:

• Structural stabilization

• Pain control

• Functional preservation
• Reduced need for open surgery

This approach is crucial in patients who are not ideal surgical candidates.
