[Compatibility and allergies of osteosynthesis materials]

Area of Science:

• Orthopedic Surgery
• Biomaterials Science
• Trauma Surgery

Background:

• Metal implants are standard in orthopedic and trauma surgery for osteosynthesis.
• Steel implants can corrode due to friction, leading to encapsulation and potential incompatibility or infections.
• Titanium implants offer better allergic compatibility but can fracture during removal.

Purpose of the Study:

• To compare the advantages and disadvantages of steel versus titanium implants in osteosynthesis.
• To highlight material removal challenges and risks associated with each implant type.
• To inform clinical decisions regarding implant selection based on stability, allergy, and removal considerations.

Main Methods:

• Review of existing literature on steel and titanium implant performance in osteosynthesis.
• Analysis of corrosion, allergic reactions, material fracture, and removal complications.
• Consideration of factors influencing implant success, including stability and tissue integration.

Main Results:

• Steel implants may exhibit increased corrosion and fluid border formation, raising concerns for incompatibility and infection.
• Titanium implants present challenges in material removal due to frequent fractures and potential adhesion/ingrowth issues.
• Current evidence does not suggest modern steel implants cause more allergic reactions than titanium.

Conclusions:

• The choice between steel and titanium implants for osteosynthesis requires careful consideration of material stability, loosening risk, allergy potential, and ease of removal.
• Both materials have distinct failure modes and complications that must be weighed in clinical practice.
• Further research may be needed to fully elucidate long-term outcomes and optimize implant material selection.
