Clinical and functional outcome of percutaneous bone marrow injection in delayed union and non-union of long bone fractures

Abstract

Non-union and Delayed union is still major challenge to the orthopaedic surgeon. Bone grafting are the basic principle in the treatment of non-union and delayed union. However complications is always concern. To minimize this risk, percutaneous bone marrow injection has been suggested as an alternative, this provides a source of oestrogenic cells with osteoinductive effect.Aim: To study percutaneous bone marrow injection in delayed union and non-union of long bone fractures. Materials and methods: The study Sample will be taken from the patients treated in P.D.U. Medical College and Hospital diagnosed as a delayed and non-union on basis of x rays. Under general or spinal anaesthesia, bone marrow was aspirated from the anterior superior iliac crest OR posterior superior iliac spine using bone marrow aspiration needle. The aspirate was injected percutaneously into and around the fracture site under fluoroscopy control. Results: In our study of 30 cases of Delayed union and non-union, 19 (63.33%) cases achieved Union while 11(36.67%) cases Union not achieved by using percutaneous bone marrow injection. Conclusion: Bone marrow injection technique is simple technique which has high oestrogenic potential. This minimally invasive procedure is safe, easy, simple, economical and short procedure.
