Other Tendon Injuries

• Other Tendon Injuries - FCU

  • flexor carpi ulnaris (FCU) and palmaris longus are the only tendons to not pass through an enclosed sheath
  • therefore not prone to stenosing conditions/triggering
  • Overuse and degeneration or acute injury
  • Features: anteromedial  pain, activity related
  • Aggravated by flexion and ulnar deviation, eg hammering, request sports
  • Additional tests: resisted flexion and ulnar deviation
  • Treatment of relative rest then stretch and strengthen may be most appropriate

  
• Other Tendon Injuries - ECU

  • extensor carpi ulnaris is part of the TFCC
  • has a tendon sheath – prone to stenosing tenosynovitis, tendinitis, fraying
  • Associated with club and racquet sports
  • Associated ulnar side wrist or DRU joint injury can be present making diagnosis challenging
  • Traditional testing of resisted extension and ulnar deviation also loads TFCC -> conflicting results.
  • Features: posteromedial pain, activity related
  • Aggravated by extension and ulnar deviation
  • Treatment: activity modification then build capacity through strengthening
