New classification system for long-bone fractures supplementing the AO/OTA classification.

This article describes a novel, clinically oriented classification system for long-bone fractures that is simple, reliable, and useful to predict treatment method, complications, and outcome. The reliability and memorability of the new classification were statistically tested and compared with the AO-Müller/Orthopaedic Trauma Association (AO/OTA) long-bone fracture classification. The proposed classification system was also clinically validated with a targeted pilot study designed for content and clinical outcome retrospectively reviewing 122 closed tibial shaft fractures, which were used as a representative paradigm of long-bone fractures. Statistical evaluation showed that the proposed classification system had improved inter- and intraobserver variation agreement and easier memorability compared with the AO/OTA classification system. The clinical validation study showed its predictive value regarding selection of treatment method, complication rate, and injury outcome.The proposed classification system proved simple, reliable, and memorable. Its clinical value appeared strong enough to justify the organization of larger studies for a complete assessment of its clinical usefulness for all long-bone fractures.
