Abstract

Abstract:

BACKGROUND: Allogenic bone is a clinical commonly used bone graft material, but the osteoinductive capacity is the biggest problem.
OBJECTIVE: To evaluate the effect of allogeneic bone combined with autologous bone marrow stem cells on the repair of bone defects after scraping or resection of benign bone tumors and tumor-like lesions.
METHODS: Sixty-five cases of benign bone tumors (including patients with tumor-like lesions) were divided into two groups according to bone graft. There were 35 cases in the composite bone marrow stem cells for bone graft group, and 20-40 mL red bone marrow were extracted from anterosuperior iliac spine or iliac spine on both sides according to the expected amount of bone graft, then the bone marrow stem cells were isolated, purified, cultured and amplified for standby, and the bone marrow stromal stem cells and allogeneic bone particles were fully blended before bong graft. After tumor scraping or resection, the blended bone marrow stromal stem cells and allogeneic bone particles were implanted into the bone defect region. In the bone graft group, the bone defect was implanted with allogeneic bone soaked with saline for half an hour. X-ray examination was performed at 1, 3, 6 and 12 months after treatment to compare the fuzzy boundary and the time for disappear, and the postoperative complications were observed.
RESULTS AND CONCLUSION: All the 62 patients were followed-up for more than 12 months. The fuzzy boundary time and disappear time in the composite bone marrow stem cells for bone graft group were shorter than those in the bone graft group (P < 0.05). In the composite bone marrow stem cells for bone graft group, one case appeared rejection and healed after treated with immunosuppressive agents for 2 weeks, and no complication observed in two groups. The results indicate that allogeneic bone composite autologous bone marrow stem cells for bone graft can promote bone fusion and bone defect healing.
