Tendinitis of the elbow is a sports injury , often from playing tennis or golf. You may also get tendinitis from overuse of the elbow. Other causes of elbow pain include sprains and strains , fractures (broken bones), dislocations , bursitis , and arthritis . Treatment depends on the cause.

Pathophysiology, Underlying Causes & Clinical Presentation

In Elbow Injuries and Disorders (M77.8), physiological disruption stems from subchondral bone remodeling [Elbow Injuries and Disorders M77.8], Cross-referenced with NIH MeSH (Elbow Injuries, Tennis Elbow), informing Osteoarthritis, Gout & Joint Pain protocols that track Serum Uric Acid in Elbow Injuries and Disorders (M77.8: (Gout Target)) (< 6.0 mg/dL (< 5.0 mg/dL with tophi) (M77.8)).

Common Symptoms & Clinical Signs

  • • Presentation of Elbow Injuries and Disorders (M77.8): sudden, intensely painful, in Elbow Injuries and Disorders (M77.8: red swollen big-toe)
  • • Secondary Elbow Injuries and Disorders clinical sign: localized tendon or in Elbow Injuries and Disorders (M77.8: bursa tenderness limiting)
  • • Symptom flares in Elbow Injuries and Disorders correlating with Weight-Bearing Joint Radiograph [Elbow Injuries and Disorders M77.8] deviation outside Preserved joint-space width (M77.8)
