[Treatment of bone cyst by transplantation of autologous bone marrow combined with allograft bone].

OBJECTIVE

To investigate the clinical result of treatment of bone cyst by transplantation of the autologous bone marrow combined with the allograft bone.

METHODS

From February 2004 to March 2006, 13 patients with bone 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 in the 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.
