Introduction: Hip fractures represent a public health problem worldwide, with 300,000 new cases every year. An important part of these patients will need a hip arthroplasty as a definitive treatment. One of the controversial topics is whether to use a cemented or uncemented stem. Spotorno et al. established criteria for this decision. However, one of the parameters is the Singh Classification, has a low interobserver reliability. The purpose of this study is to learn Spotorno's and Singh's interobserver agreement and how it affects the decision to cement the stem. Methodology: 100 cases of hip fractures were presented to two observers, which assigned scores using the Spotorno's criteria and Singh's classification. Decision to use a cemented or uncemented stem was recorded according to Spotorno's recommendations. Interobserver agreement was measured using Cohen's kappa. Results: Of the 100 cases, 67% were females and 33% were males, with a mean age of 74.9 years. Cohen's kappa for Singh's classification was 0.089 (slight agreement), and 0.317 for Spotorno's criteria (fair agreement). Both observers assigned the decision to use cemented stem in 99 cases, and 1 case with questionable indication, with an almost perfect agreement. Conclusion: Even though Spotorno's criteria and Singh's classification have low interobserver agreement, it doesn't seem to affect the decision making for using cemented or uncemented stems in patients with hip fractures. More studies are necessary to confirm this situation in patients undergoing hip arthroplasty due to other causes.
