Delayed fixation of displaced femoral neck fractures in younger adults

We report the results of 52 patients aged 20-55 years with displaced femoral neck fractures, in whom delayed closed reduction and internal fixation was performed. Seven patients developed avascular necrosis (AVN) and non-union was seen in five patients. Whereas most patients with non-union were subjected to repeat procedures, none of the patients with AVN required surgery. The follow-up averaged 40 months (range 22-64 months). Three patients were lost to follow-up. Functional outcome was defined by Judet's system. Good to excellent functional outcome was achieved in 45 cases. The study demonstrated that delayed closed reduction and internal fixation of displaced fractures in young adults which, we believe, is the prevalent form of treatment of these injuries in the developing world results in high rate of fracture union and good functional outcome. The rate of AVN, however, may be a concern if the patients are followed for a longer period. (c) 2007 Elsevier Ltd. All rights reserved.
