Aetiology

  • Commonly result from volar lacerations

Pathophysiology

Classification

  • Classified by the zone of injury

  • Zone II (no mans land) - zone from FDS insertion (just distal to PIP joint) to the A1 pulley
    • These injuries are very difficult to treat

Clinical presentation

  • Loss of active flexion strength or motion of the involved digits

Investigations

  • X-ray to assess for associated fracture
  • US - to assess suspected lacerations

Management

  • Conservative - wound care, early ROM
  • Surgical - flexor tendon repair/reconstruction/transfer
