Abstract: Non-union and Delayed union is still a 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 a concern. To minimize this risk, percutaneous bone marrow injection has been suggested as an alternative, this provides a source of oestrogenic cells with an 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 a 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 was not achieved by using percutaneous bone marrow injection.
Conclusion: The bone marrow injection technique is a simple technique which has high oestrogenic potential. This minimally invasive procedure is a safe, easy, simple, economical and short procedure.
