Lateral and medial epicondylitis, pronator teres syndrome (PTS), anterior interosseous syndrome, posteromedial elbow impingement, valgus extension overload syndrome, triceps tendon rupture, and biceps tendon rupture are the miscellaneous lesion of the elbow which are broadly described in this chapter. The prevalence of lateral epicondylitis has been estimated to range from 1% to 3% of the population. Typically, patients with lateral epicondylitis will present with pain over the lateral elbow, typically sharp with rare accompanied swelling. Most cases of lateral epicondylitis can be treated nonoperatively. Medial epicondylitis is often referred to as “golfer’s elbow”. PTS is a compression neuropathy of the median nerve at the elbow. Standard treatment of rest, ice therapy and elevation is recommended in young athletes prior to injections and/or surgical decompression. The anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a motor branch of the median nerve, causes pain in the forearm and a characteristic weakness of the pincer movement of the thumb and index finger. Posterior elbow pain caused by mechanical abutment of bone and soft tissues in the olecranon fossa, which leads to osteophyte formation in the medial aspect of the olecranon fossa. Valgus extension overload is an uncommon cause of posterior elbow pain in most athletes but it is frequently seen in throwing athletes. Rupture of triceps tendon are present with early partial or complete tears and require acute or delayed repair.
