[Pseudarthroses of the long bones]

Area of Science:

• Orthopedic Surgery
• Bone Healing Biology

Background:

• Pseudarthrosis, commonly known as fracture non-union, occurs in approximately 10% of fractures, particularly in long bones.
• This condition leads to persistent pain, impaired limb function, and significant socioeconomic costs due to complex treatments and indirect expenses.
• Effective management necessitates a nuanced therapeutic approach tailored to individual patient factors.

Purpose of the Study:

• To emphasize the importance of analyzing pseudarthrosis using the diamond concept for successful treatment planning.
• To discuss potential therapeutic strategies, including extracorporeal shock wave therapy and operative revision.

Main Methods:

• Analysis of pseudarthrosis based on the "diamond concept" (biological, mechanical, stability, infection).
• Review of current treatment strategies for fracture non-union.
• Consideration of non-operative (extracorporeal shock waves) and operative interventions.

Main Results:

• The diamond concept provides a framework for understanding and planning pseudarthrosis treatment.
• Extracorporeal shock wave therapy may be beneficial in specific cases.
• Operative revision is frequently required to enhance biomechanical stability and local biology.

Conclusions:

• A differentiated therapeutic strategy is essential for managing pseudarthrosis.
• The diamond concept is crucial for successful treatment planning.
• Optimizing biomechanical stability and local biology through operative revision is often necessary for successful outcomes.
