[Autogenous bone marrow graft for the management of nonunion of tibia].

OBJECTIVE: To investigate the effect of percutaneous bone marrow graft for the management of nonunion of tibia. METHODS: From March 1996 to June 2000, 56 cases with nonunion of tibia were treated by autogenous bone marrow graft. Among them, there were 38 males and 18 females, aged from 19 to 72 years. A marrow needle was inserted into the site of the nonunion under the X-ray, the autogenous bone marrow was injected into the site of nonunion. Compression bandage and appropriate immobilization material were applied after operation. This procedure was repeated every month, 2 or 3 times was needed. RESULTS: 56 patients were followed-up for 4 months to 4 years and 2 months, averaged 2.8 years. Fracture healed in 53 cases and X-ray displayed fracture line disappeared and a great deal of continuous callus formed, and nonunion in 3 cases. CONCLUSION: Percutaneous autogenous bone marrow graft can play a role in osteogenesis at the site of nonunion. It is easy to aspirate bone marrow and the operation is simple. It has clinical application value for the satisfactory effect.
