Treatment outcomes of undisplaced femoral neck fractures treated with cannula screws in patients over 65 years of age

Abstract

Background: Femoral neck fracture is a common discomfort in elderly people, often caused by osteoporosis and a trauma with low energy, such as falling. Considering that during the time, it seems that the effect of treatment with prosthesis is better than fixation, this study aimed to investigate the treatment outcomes of undisplaced femoral neck fracture treated with cannula screws in patients over 65 years of age. Methods: In this retrospective study, 50 elderly patients with undisplaced femoral neck fractures treated with cannula screws were enrolled. The postoperative complications, including avascular necrosis of the femoral head, nonunion, infection, fixation fail, and postoperative outcomes (using the questionnaire Harris) were assessed, and the patients were compared on postoperative outcomes. Findings: 20 men and 30 women with an average age of 6.63 ± 71.68 years were enrolled in this study. 46 had high blood pressure, 18 diabetes mellitus, 26 cigarette smoking, 8 avascular necrosis, 12 recurrent surgery, 26 non-union fracture, 18 postoperative infection, and 28 had fixation fail. 9 patients scored excellent and 19 patients received good score from the Harris questionnaire. Moreover, the amounts of avascular necrosis, nonunion fracture, postoperative infection, fixation fail, and mean postoperative walking time were significantly higher in patients with poor treatment results (P < 0.05). Conclusion: The results of the surgery were fairly good in our study according to the Harris scoring system. On the other hand, some complications were reported such as avascular necrosis. © 2019, Isfahan University of Medical Sciences(IUMS). All rights reserved.
