Introduction
Pain at the lateral epicondyle of the elbow due to tendonitis/tendinosis of the extensor carpi radialis brevis, extensor digitorum communis &/or the extensor carpi radialis longus.
Etiology
- repetitive eccentric extensor muscle overload
- in tennis
- improper grip size
- strings too tight
- metal racquet
- practice > 2 hours/day
- improper backhand technique
Epidemiology
- beauticians, painters, golfers, tennis players, weight lifters
Pathology
- tendonitis of the extensor muscles at the lateral humeral epicondyle
- does not affect elbow joint
Clinical manifestations
- pain & tenderness over lateral elbow worsened by activities that cause resisted extension of the wrist
- increased pain with resisted extension at wrist with elbow fully extended
- diminished grip strength may be present
- motion loss of 10 degrees compared with unaffected side with chronic cases
Laboratory
generally of no value
Radiology
indicated in cases of trauma
Differential diagnosis
(also see epicondylitis)
- radial tunnel syndrome
- paresthesia
- positive Tinnel's sign over nerve
- tenderness to palpation 4 cm distal to the lateral epicondyle
- pain with resisted supination with elbow extended
- weakness of full finger extension
- interosseous nerve entrapment (within supinator muscle)
- tenderness posterior to the lateral epicondyle
- small finger extensor weakness
- lack of tenderness with paresthesia suggests cervical radiculopathy
- radial head fracture
- lateral epicondyle evulsion fracture
- radiculopathy of C6 nerve root
- olecranon bursitis
Management
(see epicondylitis)
- NSAIDs (oral & topical)
- counter force (tennis elbow) brace
- wrist splint in 20 degree flexion relieves tension on the extensor mass
- physical therapy provides early benefit that disappears by 1 year[9]
- stretching & strengthening exercise of the extensor muscles
- glucocorticoid injection at point of maximum tenderness over the radial epicondyle of the humerus
- provides prompt relief of symptoms[2]
- short-term benefit, but worse-off at 1 year[3][8][9]
- avoid glucocorticoid injection[11]
- surgical release of extensor tendon is rarely needed
- extracorporeal shock wave therapy[4][5][6]
- use of botulinum toxin suggested[7]
- transcutaneous electrical nerve stimulation (TENS) not useful[10]
