Managing AVN following internal fixation: treatment options and clinical results

Area of Science:

• Orthopedic Surgery
• Regenerative Medicine
• Biomedical Engineering

Background:

• Avascular necrosis (AVN) of the femoral head is a debilitating condition causing osteonecrosis and structural compromise.
• It affects patients of all ages, posing unique challenges in young, active adults due to high functional demands.
• Effective management of AVN in young adults is crucial to relieve pain, preserve joint function, and improve quality of life.

Purpose of the Study:

• To review and summarize current treatment strategies for avascular necrosis (AVN) of the femoral head in young adults.
• To evaluate the clinical outcomes of hip-preserving surgeries versus hip arthroplasty for managing AVN in this demographic.
• To explore emerging treatment modifications and technologies that may alter the course of femoral head osteonecrosis.

Main Methods:

• Comprehensive literature review of studies on avascular necrosis (AVN) treatment in young adults.
• Analysis of treatment options including hip-preserving techniques and hip arthroplasty.
• Evaluation of clinical results and long-term outcomes associated with different management strategies.

Main Results:

• Treatment approaches for AVN vary based on disease stage, with options including hip preservation and arthroplasty.
• Hip-preserving surgeries may alter proximal femur morphology, potentially complicating future arthroplasty.
• Arthroplasty in young adults may necessitate repeat revision surgeries over a lifetime.

Conclusions:

• Management of AVN in young adults requires careful consideration of treatment goals and potential long-term implications.
• Advancements in treatment modifications and technology offer potential to positively impact the progression of femoral head osteonecrosis.
• Further research is needed to optimize treatment strategies for long-term functional preservation in young AVN patients.
