Comparison of the efficacy between elastic intramedullary injection and autologous bone marrow blood injection in the treatment of bone cyst in children / 中国骨伤

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of autogenous bone marrow injection and elastic intramedullary injection in the treatment of bone cyst in children.@*METHODS@#From January 2012 to December 2016, 56 children with simple bone cyst were divided into two groups autogenous bone marrow blood injection group and elastic intramedullary needle group. There were 28 cases in the autogenous bone marrow blood injection group, 16 boys and 12 girls, aged (7.7±1.9) years old, 10 cases of proximal humerus, 8 cases of proximal femur, 6 cases of proximal tibia and 4 cases of femoral shaft. In the elastic intramedullary needle group, there were 28 cases, 18 boys and 10 girls, aged(7.5±2.2) years old, 11 cases of proximal humerus, 7 cases of proximal femur, 5 cases of proximal tibia, 4 cases of femoral shaft and 1 case of distal femur. The treatment effect was evaluated by Capanna standard.@*RESULTS@#All the patients were followed up, including 17 to 35(25.6±4.2) months in the elastic intramedullary needle group and 19 to 35(27.4±4.8) months in the autogenous marrow blood injection group. According to Capanna's evaluation standard of bone cyst, 27 patients in the elastic intramedullary needle group were treated effectively(25 patients cured, 2 patients healed but some remained lesions), 1 patients recurred, 0 patient had no response to treatment; 18 patients in the autogenous bone marrow blood injection group were treated effectively(13 patients cured, 5 patients healed but some remained lesions), 8 patients of cyst recurred, 2 patients had no response to treatment; the difference between the two groups was statistically significant(<0.01). The overall cure time was calculated by the follow-up of 25 cases in the elastic intramedullary injection group and 13 cases in the autogenous marrow blood injection group. The cure time was(20.2±3.5) months in the elastic intramedullary injection group and(27.7±4.9) months in the autogenous marrow blood injection group. The difference was statistically significant(<0.05).@*CONCLUSIONS@#For the treatment of bone cyst in children, the therapeutic effect of elastic intramedullary needle is better than that of autogenous bone marrow blood injection, and the cure time is shorter.
