Less invasive treatment for delayed or nonunion: The use of percutaneous autologous bone marrow injection
Keywords:
Less invasive treatment, delayed or nonunion, autologous bone marrow injectionAbstract
Fracture heals by advanced vital process in which bone regenerates by restoring the integrity of skeletal tissue. In non-union fracture healing cascade has ceased and it'll not progress while not intervention. Autologous bone marrow grafts are regarded as vital material for treating non-unions. Recently there has been a trend towards a lesser invasive technique in which bone marrow graft i.e. autologous in nature, is taken from iliac bone by aspiration needle and is administered percutaneously at non union site. Material and Methods: 30 cases of post-traumatic delayed and non-union of fracture tibia with internal fixation or fractures more than 12 weeks with abnormal mobility without infection were included in the study. Baseline RUST scoring was calculated for each fracture and bone marrow aspirate injections were given at fracture site by percutaneous route. Result: On the premise of final RUST scores at half dozen months and clinical analysis, union of 23(76.67%) fractures were achieved by autologous bone marrow injections by percutaneous route whereas 7(23.33%) cases were failed even after three attempts of procedure. The complications of the procedure are negligible and is safe. The mean time of radiological union in our study was fourteen weeks with a spread of 11-22 weeks. Conclusion: On the premise of our results and observations within the study we are able to conclude that regional autologous bone marrow injection is an efficient method compared to traditional open bone grafting with less invasive technique, will be performed as out-patient procedure underneath local anesthesia, cheap and safe with negligible complication rate at donor or recipient graft site.
