Sternal Injuries in Sport: A Review of the Literature.

Sternal fractures were first described in published literature in the 19th century as a complication of traumatic injury. Though sternal fracture and other sternal injuries have been described in trauma literature, there remains a paucity of literature with regards to sternal injury in sport. Sternal injury may include disruption at the body, manubrium and xiphoid process, or at associated sternoclavicular, manubriosternal, and xiphisternal joints. In the athlete it is imperative to evaluate sternal injury with consideration of potentially devastating cardiothoracic complications. Return-to-play protocols should be individualized, taking into account subjective history, objective physical examination and diagnostics, current clinical guidelines, and individual sport-specific considerations. The literature regarding sternal injury is reviewed, with emphasis on sport-specific pathology, management, and return to play.

Evaluating the Athlete with Suspected Exercise-Induced Asthma or Bronchospasm.

Exercise-induced asthma (EIA) and exercise-induced bronchospasm (EIB)/bronchoconstriction (EIC) describes two clinical entities by which exercise triggers bronchial hyperresponsiveness. Exercise is a common trigger of bronchospasm in the asthmatic (EIA), as well as athletes without the underlying inflammation associated with asthma (EIC/EIB). Approximately 10% to 20% of the general population have EIA or EIB (). The approach to the diagnosis and subsequent management relies on the clinician's ability to recognize clinical signs and symptoms, then selecting the correct diagnostic test. A baseline spirometry/pulmonary function test is recommended for all athletes to evaluate for underlying asthma. Subsequent direct or indirect bronchial provocation testing is recommended to correctly diagnose EIA or EIB (). Athletes should not be treated empirically with bronchodilators based on symptoms alone without confirmatory spirometry and provocative testing.
