Q

What are some major types of tendon injury and an example

A
  • Degeneration e.g. Intrasubstance mucoid degeneration of Achilles
  • Inflammation e.g. De Quervains Stenosing Tenovaginitis in thumb
  • Enthesiopathy e.g. Tennis elbow
  • Avulsion
  • Traction Apophysitis e.g. Osgood Schlatter’s
  • Rupture e.g. common in achilles
  • Laceration e.g. finger flexors
