| Sumario: | INTRODUCTION: Femoral neck fractures have been historically diagnosed by anteroposterior (AP) and lateral (L) radiographic views. We analyzed the importance of the L view for management of femoral neck fractures, using the Garden's classification system.
MATERIALS AND METHODS: Slides were elaborated with AP and L radiographic views of 100 patients with femoral neck fractures admitted to our emergency department. Three hip surgeons assessed independently AP views only and then AP and L views together using Garden's classification system.
RESULTS: No statistically significant differences (Kruskal Wallis 0, p=1) were found while comparing categories among Garden's classification system, after assessing L views. There was an 81 % (p < 0.001) agreement of Garden category between AP and AP combined with L views. When analyzing patients with changing categories between displaced and non displaced after assessing L view images, we found a 5% (n=5, CI 95% 1-11%) of change. For comparing AP Garden with L view Garden, we used a quadratic weighted kappa method.
CONCLUSIONS: There is a high agreement in the Garden category when comparing AP with combined AP and L observations. Five patients would have received a different surgical treatment dependent on the hip surgeon who assessed the radiographs. This highlights the relevance of routinely L radiographs whenever a femoral neck fracture is suspected.
