Sažetak
Aim: To determine which of the classification systems for the femoral neck fracture between AO group, AO subgroup, Garden and Pauwels is much more reliable and reproducible to predict method of treatment, radiological predict of non-unionand predict of outcomes. Methods: Five observers classified 77 randomly selected anterior-posterior (AP) and lateral view preoperative radiographs of the femoral neck fractures according to AO group, AO subgroup, Garden and Pauwels classification systems.The procedure was repeated on the same radiographs after three months. First classification is used to calculate interobserver agreement by kappa value between observers, while the first and second classification has served to calculate intraobserver kappa value for each examiner. Results: Overall mean for classification system for interobserver agreement is: AO 0.44, AO subgroup 0.17, Garden 0.41 and Pauwels 0.19. Mean intraobserver agreement for AO group 0.56, AO subgroup 0.38, Garden 0.49 and Pauwels 0.38 coefficient kappa value. Conclusion: Garden and AO group are the only ones useful for the division of femoral neck fractures on without displaced and with displaced but not for clinical use. AO subgroup and Pauwels classification are not recommended forfurther use.
