While the Neer classification has been the most widely used, it has poor inter and intraobserver reliabilities. However, no entirely satisfactory fracture classification is available to serve as a guide to modern treatment and predict an outcome. In addition to the typology of the fracture, decision-making is also influenced by underlying patient and surgeon-related factors. PHFs account for 45% of upper limb fractures and 4-5% of all the overall fractures. Proximal humeral fractures (PHFs) are one of the most frequent fractures among the elderly and are the third most fractures after hip and wrist fractures. The application of 3DPMs is effective for preoperative fracture planning and the modeling of patient-specific hardware. The 3DPMs for evaluating diagnostics are comparable to CT images but superior to the surgical technique agreement. Classification systems like Neer and Hertel offer poor reliability between operators. The ST reliability using 3DPMs (ICC = 0.755 ) was statistically superior to traditional imaging (ST-RX ICC = -0.004 ( ) ST-CT ICC = 0.429 ). IT reliability using CT scan and 3DPMs (ICC = 1 ) assessed better agreement compared with X-rays IT. The Neer and Hertel classifications between imaging types had similar ICC values between raters with no statistical differences. Nine patients with PHF were included in the study (66% female). Interobserver reliability was calculated through the intraclass correlation coefficient (ICC). The questionnaire for each method regarded Neer classification, Hertel classification, treatment indication (IT), and surgical technique (ST). In addition, 9 PHFs were assessed by 6 evaluators through a questionnaire and double-blinded administered for each imaging (X-ray and CT scan) and 3DPMs for each fracture. The inclusion criteria were elders aged >65 years, fracture classification AO/OTA 11 B and 11 C, and no pathological fractures or polytrauma. Our objective is to compare interobserver reliability in diagnostic evaluation of PHFs using 3DPMs compared to traditional imaging. In terms of fracture classification and surgical indication, PHFs have poor interobserver agreement between orthopedic surgeons using traditional imaging such as X-rays and CT scan. The present study aims to conduct the diagnostic evaluation and therapeutic efficacy of the 3D-printed models (3DPMs) for the PHFs, compared with the standard imaging. PHFs are assessed clinically through conventionally standard imaging (X-ray and computed tomography (CT) scans). Proximal humerus fractures (PHFs) are one of the most frequent fractures in the elderly and are the third most fractures after those of the hip and wrist.
