  • Flexor tenosynovitis (FTS) is a serious infection in the upper extremity digit, often resulting in high morbidity.

Discussion:

    • FTS usually follows penetrating trauma to the volar aspect of an upper extremity digit.
    • The infection spreads quickly through the flexor tendon sheath, posing risks of significant structural hand damage, potential finger amputation, or even death.
  • Kanavel Signs - Key Indicators of FTS:
    •
        • Symmetrical swelling of the affected finger.
        • The finger held in a flexed position.
        • Pain during passive finger extension.
        • Tenderness along the flexor tendon sheath.
      • Patients may also exhibit systemic symptoms like fever and chills.
      • Diagnosis largely depends on clinical signs and symptoms, as lab tests and imaging are not typically conclusive.
  • Management in the ED:
    •
      • Intravenous antibiotics.
      • Urgent consultation with a surgical specialist.
