Abstract Abstract Fracture fixation using plates has evolved over time. This progress is evident both in the types of devices used—such as the development of locking plates—and in the conceptual approach of orthopedic surgeons, including greater respect for soft tissue and minimal manipulation of it. In summary, locking plates function as internal fixators, where the plate acts as a rod and the screws play the role of Schanz pins. This structure, which functions as a solid, unified unit, is less dependent on bone quality, making it especially useful in the fixation of articular surface fractures and metaphyseal fractures, particularly when using minimally invasive approaches. Numerous advancements in the evolution of these plates—such as Variable Angle Plates and Locking Compression Plates (LCP)—offer surgeons significant intraoperative flexibility. Understanding concepts such as working length and screw density greatly assists surgeons in screw placement. Although there are no absolute contraindications for the use of locking plates, their use is not recommended for simple diaphyseal fractures. Through ongoing evaluation of design, biomechanics, and surgical concept comprehension, it is anticipated that newer and more advanced locking plates will be developed in the near future through the collaboration of orthopedic surgeons and engineers. This continuous improvement reflects the dynamic nature of orthopedic technology and surgical techniques in fracture management.

Abstract Background: To improve the education of orthopaedic residents and enhance patient care in the Iran's healthcare system, it is necessary to gather information about the current status of scientific, practical, and research-based education for residents.
Methods: The research project initially focused on examining the executive curriculum in 14 centers affiliated with 6 different medical universities. Subsequently, an investigation was conducted into human resources, infrastructure, operating room facilities, educational and research outcomes, as well as the regular implementation of practical examinations to evaluate the performance of residents during their residency years. All the aforementioned aspects were covered using a comprehensive questionnaire, which was distributed via the "Formafzar.com" website as a link to the heads of departments in these centers by the Iranian Orthopaedic Association. The relationship between facilities and equipment and passing the future specialized orthopaedic board examination was also evaluated.
Results: Among the examined centers, only 20% adhered to the criteria of Iran educational curriculum in all aspects of human resources, education, and research.
Conclusion: a regular evaluation of teaching methods used by international centers and the national curriculum is necessary for orthopaedic training centers in Iran. Additionally, regulatory systems should monitor the training process of orthopaedic residents to standardize services, equipment, and educational programs in the country.
