  • Summary
  • Etiology
  • Pathoanatomy
    • Pathoanatomic components
      • loss of intrinsics
        • leads to loss of baseline MCP flexion and loss of IP extension
      • strong extrinsic EDC
        • leads to unopposed extension of the MCP joint
        • remember the EDC is not a significant extensor of the PIP joint
          • most of the MCP extension forces on the terminal insertion of the central slip come from the interosseous muscles
      • strong FDP and FDS
        • leads to unopposed flexion of the PIP and DIP
