Core Tip

Core tip: Percutaneous expanded core decompression and mixed bone graft technique is simple, safe, and reliable. In our cases no serious perioperative complications were observed. Advantages of the single blade expandable reamer are obvious. The adjuvant is inexpensive and easy to obtain. Thus, this technique is an effective joint-preserving surgical treatment for patients with early stage of osteonecrosis of the femoral head. It is easy to master as well as costs less. We present it here in the hope that colleagues in other institutions could try to use it and together to fully demonstrate its effectiveness.
