Patients and methods: Between January 2013 and December 2014, radiological images of a total of 60 patients (13 males, 47 females; mean age: 78.9±21.9 years; range, 61 to 96 years) with the diagnosis of intertrochanteric femur fracture were analyzed. Radiographs were evaluated and classified by five residents and five orthopedics and traumatology surgeons according to the Evans, Boyd-Griffin, Evans/Jensen, OTA, and Tronzo classification systems. Intra- and interobserver reliability were calculated using the kappa statistics. Results: The worst intraobserver compatibility among the residents was the classification system with OTA subgroups (?=0.516), while the classification system with the best intraobserver fit was found to be OTA main groups (?=0.744). The worst agreement among surgeons was in the Evans classification system (?=0.456). However, the best intraobserver agreement was in the OTA main groups (?=0.741). The best interobserver agreement was observed regarding the OTA main groups (?=0.699). Conclusion: The classification that has the best harmony both among residents and surgeons, and between residents and surgeons is the OTA main group classification.eninfo:eu-repo/semantics/openAccessArticle33118719235361094WOS:0007789608000222-s2.0-85127442340Q310.52312/jdrs.2022.498N/A522474
