1 Lateral epicondylosis (tennis elbow) is a degenerative, noninflammatory condition of the common extensor origin at the lateral epicondyle of the elbow
Tennis elbow has a prevalence of 1%-3%, peaking at age 35-50 years. (1) It is associated with smoking and with a combination of repetitive and forceful manual activities. (2)
2 The diagnosis is clinical based on lateral elbow pain and epicondyle tenderness
Provocative tests include pain with resisted extension of the long fingers or wrist when the elbow is extended. Pain distal to the epicondyle suggests radial tunnel syndrome and warrants orthopedic referral. Clinicians should obtain radiographs for patients with loss of range of motion, locking or catching of the elbow to assess for osteoarthritis and osteochondritis dissecans. Ultrasonography and magnetic resonance imaging have variable sensitivity and specificity, and are not routinely required. (1)
3 Symptoms of tennis elbow are managed with physiotherapy and anti-inflammatory agents
