Segmental Bone Loss Reconstruction Using Ring Fixation.

Area of Science:

• Orthopedic surgery
• Biomaterials science

Background:

• Ring fixation is a key technique for treating bone defects.
• Distraction osteogenesis enables significant new bone formation.

Purpose of the Study:

• To review the efficacy and advancements of ring fixation in treating bone defects.
• To highlight the benefits and drawbacks of ring fixation techniques.

Main Methods:

• Review of current literature on ring fixation and distraction osteogenesis.
• Analysis of advancements in hardware and techniques.

Main Results:

• Ring fixation facilitates high-quality new bone growth and offers advantages in infection control, limb alignment, and soft tissue coverage.
• Drawbacks include prolonged treatment, pin site issues, joint contractures, and challenges in specific anatomical areas like the thigh.

Conclusions:

• Despite drawbacks, advancements like hydroxyapatite coated pins and combined internal fixation enhance effectiveness.
• Ring fixation remains a primary treatment for substantial bone defects in various clinical settings.
