Pain triceps tendon tear.

Long- and short-axis fat- and water-weighted images were performed. 

  • The medial collateral ligament is intact. The common flexor tendon is normal. 
  • The radial collateral ligament is intact. The lateral ulnar collateral ligament is intact. 8mm undersurface partial-thickness tear of the proximal common extensor tendon consistent with clinical lateral epicondylitis. 
  • Biceps and brachialis tendons are normal. 
  • Full-thickness tear of the distal triceps tendon from the olecranon with 3cm of retraction. The distal tendon is thickened and edematous. Associated grade 2 muscular strain of the distal triceps muscle with crimping of muscle fibers and edema. No well-defined intramuscular hematoma. 
  • The cubital tunnel and ulnar nerve are normal. 
  • No bony fracture or contusion to suggest elbow dislocation.
  • Full-thickness tear of the distal triceps tendon with 3cm of retraction and associated grade 2 muscular strain of the distal triceps muscle. 
  • 8mm undersurface partial-thickness tear of the proximal common extensor tendon consistent with lateral epicondylitis.
