Hệ thống phân loại giúp chỉnh hình bác sĩ phẫu thuật mô tả một vấn đề, đề xuất một tiên lượng tiềm năng, và hướng dẫn cung cấp trong việc xác định phương pháp điều trị tối ưu cho một điều kiện cụ thể. Hệ thống phân loại cũng đóng một vai trò quan trọng trong các báo cáo của các dữ liệu lâm sàng và dịch tễ học, | Classification Systems in Orthopaedics Donald S. Garbuz MD MHSc FRCSC Bassam A. Masri MD FRCSC John MD MPH FRCPC and Clive P. Duncan MD FRCSC Abstract Classification systems help orthopaedic surgeons characterize a problem suggest a potential prognosis and offer guidance in determining the optimal treatment method for a particular condition. Classification systems also play a key role in the reporting of clinical and epidemiologic data allowing uniform comparison and documentation of like conditions. A useful classification system is reliable and valid. Although the measurement of validity is often difficult and sometimes impractical reliability as summarized by intraobserver and interobserver reliability is easy to measure and should serve as a minimum standard for validation. Reliability is measured by the kappa value which distinguishes true agreement of various observations from agreement due to chance alone. Some commonly used classifications of musculoskeletal conditions have not proved to be reliable when critically evaluated. J Am Acad Orthop Surg 2002 10 290-297 Classifications of musculoskeletal conditions have at least two central functions. First accurate classification characterizes the nature of a problem and then guides treatment decision making ultimately improving outcomes. Second accurate classification establishes an expected outcome for the natural history of a condition or injury thus forming a basis for uniform reporting of results for various surgical and nonsurgical treatments. This allows the comparison of results from different centers purportedly treating the same entity. A successful classification system must be both reliable and valid. Reliability reflects the precision of a classification system in general it refers to interobserver reliability the agreement between different observers. Intraobserver reliability is the agreement of one observer s repeated classifications of an entity. The validity of a classification system .
