Objective To investigate the clinical result of treatment of bonecyst by transplantation of the autologous bone marrow combined with the allograft bone. Methods From February 2004 to March 2006, 13 patients withbone cyst were treated by transplantation of the autologous bone marrow combined the the allograft bone. Among the 13 patients, 6 were males and 7 were females, ranging in age from 5 to 16 years, averaged 11.5 years. In the patients, 5 lesions were located inthe proximal humerus, 2 in the femoral neck, 3 in the femoral shaft, 2 in the proximal tibia, and 1 in the distal tibia. Among the patients, 5 had a complication of pathologic fracture. All the patients underwent an erasion of the bone cyst, and then the transplantation of the autologous bone marrow combined with the allograft bone, and 8 of them were also given an instrument fixation. Results The follow-up for 6 months to 2 years after operation revealed that 5 of the patients had an incision healing by the first intention, 5 had an effusion in the incision site, and 3 had a delayed healing of the incision. According to the Capanne criteria, the postoperative X-ray findings indicated that 10 patients had Grade Ⅰ healing, and 3 had Grade Ⅱ healing. The complete healing took 3.5-8 months,averaged 5.2 months. There was no recurrence. When the fixation instrument was removed, no pathologic fracture occurred. The function of the upper and lower limbs recovered. Conclusion Transplantation of the autologous bone marrow combined with the allograft bone is an effective and safe procedure for treatment of bone cyst.
