  • Pain is reproduced by passive extension of the wrist in supination
75
Q

ELBOW - MEDIAL/LATERAL EPICONDYLITIS - CLINICAL PRESENTATION - LATERAL EPICONDYLITIS

  • Repetitive tasks involving the wrist frequently make pain worse
  • Pain may be related to activity or occur at rest
  • The elbow looks normal and flexion and extension after fallen painless
  • Tenderness is localised to a spot just in front of the lateral epicondyle
  • Pain is reproduced by getting the pt to extend the wrist against resistance
76
Q

ELBOW - MEDIAL/LATERAL EPICONDYLITIS - PROGNOSIS

A
