Gotfried reduction and cannulated screws fixation in the treatment of femoral neck fracture in young adults


 Background: Although many available surgical procedures for displaced femoral neck fractures in young patients, there are still many challenges to achieve satisfactory results. The incidence of avascular necrosis and nonunion rates remain relatively high despite the progress in our understanding and surgical technique. The purpose of this study was to evaluate the clinical efficacy of gotfried reduction and cannulated screw fixation in the treatment of femoral neck fracture for young adults.Methods: A retrospective analysis was made on 67 cases from May 2013 to March 2019. They were divided into three groups according to the first postoperative anteroposterior view of hip X-ray: Anatomic reduction (group A), Gotfried positive buttress reduction (group B), and Gotfried negative buttress reduction (group C). The incidence of avascular osteonecrosis of the femoral head (AVN) and the Harris scores of hip joints were compared in three groups at the last follow-up.Results: There were 21 cases (mean age,49.7 ± 11.6) in group A, 24 cases (mean age, 48.6 ± 11.3) in group B, 22 cases (mean age,48.3 ± 12.4) in group C. No significant difference in general preoperative demographics (P>0．05).The incidence of avascular necrosis of femoral head in Group A, B, and C was 19.05%,20.83%, and 22.73 %, respectively, showing no significant difference between groups(P=0．156). The mean Harris hip scores at the final follow-up for groups A (85．6±6．7)and B (84．5±6．2) were significantly higher than group C (74．3±8.3), and the difference was statistically significant(P=0．043).Conclusions: Gotfried positive buttress reduction and fixation for femoral neck fracture may lead to similar clinical results with anatomic reduction, but much better than Gotfried negative buttress reduction. For the patients of femoral neck fracture with severe displacement and difficulty in reduction, it is not necessary to pursue anatomical reduction。Achieving positive valgus reduction can also obtain satisfactory clinical results, and should try to avoid negative buttress.
