The Gartland classification is used to decide on surgery. In contrast, the John Hopkins classification system predicts clinical outcomes for patients undergoing surgery and determines the risk of reduction loss. This study aims to investigate the usability of the Gartland and the John Hopkins classification systems by pediatric and general orthopedic surgeons. The preoperative images of 200 patients who presented at a tertiary-level trauma center with a supracondylar humerus fracture were examined by 4 observers, twice at an interval of 6 weeks. The observers comprised 2 pediatric orthopedic surgeons and 2 orthopedics and traumatology surgeons. Inter- and intra-observer reliability were excellent for the first and second measurements of the Gartland classification. The inter-observer agreement of the pediatric orthopedic surgeons and the general orthopedic surgeons was found to be similar (ICC >90). Inter-observer reliability was excellent (ICC: 0.808) and good (ICC: 0.732) for the measurements of the John Hopkins classification, respectively. The inter-observer agreement of the pediatric orthopedic surgeons and the general orthopedic surgeons was not similar. The inter-observer agreement between the two pediatric orthopedic surgeons was excellent for the measurements (ICC: 0.868; ICC: 0.756, respectively). The inter-observer agreement between the two general orthopedic surgeons was good for the measurements (ICC: 0.605; ICC: 0.663, respectively). The John Hopkins classification system has good intra- and inter-observer reliability, and a high experience level increases the agreement. The Gartland classification system was not affected by experience. This should be considered when taking measurements in studies and patient management.
