Scapular snapping may vary in character and etiology. Although local conditions, such as the tubercle of Luschka or an osteochondroma, may long antedate the onset of symptoms, trauma would seem to play some part in precipitating the patient's complaints of discomfort or of disability. The sound originates as the result of contact between parts of the scapula and the chest wall. Elevation of the scapula from the chest wall leads to immediate cessation of the sound. In all instances, the localization of the noise determines the site of resection. Simple removal of portions of the scapula will result in prompt and permanent cure.
