Treatment of long bone cyst in children by autologous bone marrow blood injection and elastic intramedullary needle / 中国骨伤

ABSTRACT

OBJECTIVE@#To observe the clinical effect of autologous bone marrow blood injection combined with elastic intramedullary needle implantation in the treatment of long bone cyst in children.@*METHODS@#From January 2010 to December 2015, 29 children with long bone cyst were treated with autologous bone marrow blood injection combined with elastic intramedullary nail implantation, including 22 males and 7 females, aged 2 to 12 years old with an average age of 7.7 years old, and the course of disease was 12 to 84 months. Among them, 17 cases were proximal humerus, 9 cases were proximal femur, 2 cases were distal femur and 1 case was proximal ulna. All children with bone cyst underwent preoperative X-ray examination and CT or MRI examination if necessary. After definite diagnosis, bone marrow blood injection combined with elastic intramedullary needle support and drainage were used as treatment methods. After operation, multiple X-ray examination and follow-up were carried out. The curative effect was evaluated with Capanna bone cyst treatment evaluation criteria.@*RESULTS@#Twenty-seven of 29 children were followed up for 12 to 60 months with an average of 31.8 months. According to the evaluation criteria of Capanna bone cyst, 26 cases were cured and 1 case was partially healed with residual lesions.@*CONCLUSIONS@#Autologous bone marrow blood injection combined with elastic intramedullary needle has the characteristics of definite curative effect, high cure rate, fewer complications and objectively controllable treatment process for simple long bone cyst in children.
