Non Union of Fracture of the Neck of Femur in Young Adult

Non union is the most common complication of fracture neck of femur. Fracture of the neck of the femur has multiple factors leading to difficulties in union. Both biological and mechanical parameters contribute to the development of union complications. On biological side the lack of cambium layer of the periosteum of femor al neck and the presence of synovial fluid at the fracture site inhibit fracture union. Poor bone quality also plays a part. Mechanical parameters include the amount of vertical inclination of the fracture line, quality of reduction, stability of fixation and integrity of the posterior cortex [1]. These mechanical factors lead to an unstable fracture. Poor implant placement after fixtion contributes further to nonunion.
