Dynamization for delayed & non-union fractures of femur shaft
Journal Title: International Journal of Orthopaedics Traumatology & Surgical Sciences - Year 2017, Vol 3, Issue 2
Abstract
Aim- the effects of Dynamization of Non-united & delayed union femoral shaft fractures treated with static Intramedullary nails is studied in this study. Materials & Methods - in a series of 20 cases, during April 2015 to April 2017, in Maharaja institute of medical sciences. dynamization is done after 2-4 months of initial surgery. Successful union achieved in 85% cases. Results – of 20 cases in this study 18 cases were male and 2 cases were female, average age of 32 yrs. Dynamization was successful in 17 cases and failure in 3 cases, exchange nailing was done for failure cases. Conclusion - For Femur shaft fracture are commonly seen by orthopaedic surgeons especially in a rural setup. Before Intra-medullary interlocking nails were popular, K-nail was used for fracture shaft femur in 1970’s, this K-Nail couldn’t control the rotation of fragments so non-union and delayed union were notoriously common, more in proximal 1/3 rd. of femur. The complications like delayed/ nonunion after interlocking- intra medullary nails if encountered the answer would be Dynamization. Our study tells the efficiency of dynamization and we Identified the factors causing success and failure. We analyzed the cost compared with exchange nailing. as we conducted the procedures in a rural setup (A Tribal belt area). Dynamization is enhancing callus formation in 85% of the cases. The percentage of union rate is more than before published rates. Our study suggest dynamization is the best alternative method to exchange nail.
