(5-7) Though special imaging is rarely ordered for cases of LE, the most common radiographic finding is calcification along the lateral epicondyle within the common extensor tendon.
Enthesopathy at the origin of the wrist and finger extensors presents with pain and tenderness over the lateral epicondyle exacerbated by resisted wrist extension (tennis elbow).
We assessed severity of average pain during the day and pain under strain (visual analog scale (VAS); 0: no pain - 100 mm: maximum pain); local tenderness of the lateral epicondyle after firm pressure was applied to the painful area (0-3 point scale: absent, mild, moderate, severe) (10); pain on resisted extension of middle finger and wrist with the arm extended (0-3 point scale: absent, mild, moderate, severe); pain-free grip strength in the affected arm (average of two readings with a Jamar hand-held dynamometer-Sammons Preston, AbilityOne, US) in each patient (11).
The extensor muscle group of the forearm is weaker than the flexor group, which puts a lot of stress on the insertion of the extensor muscles--that is, the lateral epicondyle.
