Arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod in the repair of stage II femoral head necrosis / 中国组织工程研究

ABSTRACT

BACKGROUND:Although core decompression can contribute to the reconstruction of necrotic bone, its single use appears to have some deficiencies and cannot completely realize the reconstruction of the femoral head. OBJECTIVE:To explore the effect of arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod in the repair of stage II femoral head necrosis METHODS:A retrospective analysis was performed on clinical data of 79 cases of stage II femoral head necrosis admitted at the South Branch of Tongchuan People’s Hospital from February 2011 to February 2013. According to the therapeutic methods, these cases were divided into control group (40 cases) and observation group (39 cases), and were given conventional core decompression and arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod. Patients were fol owed up for 24 months, and the range of hip flexion and Harris scores on hip function and adverse events were observed and compared between two groups. RESULTS AND CONCLUSION:Al the 79 patients successful y completed the 24-month fol ow-up. By the last fol ow-up, the range of hip flexion and Harris score were significantly higher in the observation group than the control group (P<0.05). There was no failure case due to surgical material rejection. To sum up, arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod is safe and effective for repair of stage II femoral head necrosis.
