Core Decompression Techniques for Avascular Necrosis of the Hip

Surgical Techniques and Considerations

  • The American College of Radiology suggests that lesions involving <30% of the femoral head have <5% progression to collapse 1, 2, 3
  • CT imaging is valuable for preoperative planning, showing the location and extent of articular collapse that may not be visible on radiographs 4
  • 3D-printed guide plates can improve surgical precision, decrease operative time, and reduce blood loss during core decompression 4

Postoperative Management

  • Protected weight-bearing is recommended for patients following core decompression procedures 5
  • Regular follow-up with radiographic evaluation is essential to monitor disease progression 1, 2
