Joint-preserving procedures for osteonecrosis of the femoral head

Area of Science:

• Orthopedics
• Hip Preservation Surgery
• Femoral Head Osteonecrosis

Background:

• Osteonecrosis of the femoral head is a significant cause of hip joint destruction, particularly affecting individuals aged 30-50.
• It accounts for 5-18% of total hip arthroplasties (THAs) performed annually in the USA.
• High complication rates associated with THA in this demographic underscore the need for joint-preserving strategies.

Purpose of the Study:

• To review current joint-preservation techniques for osteonecrosis of the femoral head.
• To highlight the importance of early diagnosis and intervention.
• To discuss the heterogeneous results and limited evidence for various surgical approaches.

Main Methods:

• Review of published literature on surgical head-preserving procedures.
• Analysis of techniques including core decompression, stem cell augmentation, bone grafting, and osteotomies.
• Assessment of evidence supporting different treatment modalities.

Main Results:

• Various surgical techniques exist, including core decompression, stem cell augmentation, vascularized bone grafting, and osteotomies.
• Published results for these procedures are heterogeneous, with limited robust evidence.
• Early diagnosis and timely intervention are crucial for improving patient prognosis.

Conclusions:

• Effective algorithmic approaches for managing osteonecrosis of the femoral head are still evolving.
• Further research is needed to establish evidence-based guidelines for joint-preserving treatments.
• Timely intervention significantly improves the prognosis for patients with femoral head osteonecrosis.
