KEY FACTS

  • Terminology

    • Imaging

      • Top Differential Diagnoses

        • Diagnostic Checklist

          TERMINOLOGY

          • Synonyms

            • Tendon rupture, tendon tear, tendon sprain, tendon strain
              • Tendon sprain and strain are clinical rather than imaging terms used to describe partial-thickness tendon tears

          • Definitions

            • Tendon tear = discontinuity either within tendon substance or at attachment
              • Partial-thickness tear: Some of tendon fibers are torn, but this does not involve full thickness of tendon
              • Full-thickness tear: Some of tendon fibers are torn, and this does involve full thickness of tendon
              • Complete tear: All of tendon fibers are torn
              • High-grade partial tear: Partial tendon tear involving > 50% of tendon fibers
