Manubriosternal joint dislocation in contact sport

Abstract

A 17 year old man developed chest pain and shortness of breath immediately after a scrummage while playing rugby football. A lateral chest radiograph showed a dislocated manubriosternal joint, with no associated injuries. This has not been previously reported in a sporting setting. This injury should be considered in flexioncompression injury of the thorax.

Manubriosternal Disjunction a New Approach for Surgical Repair

“…Conversely, in type II, the body of the sternum is moved anteriorly (5). The second type is more frequent and caused by hyperflexion injury of the torso, occuring together with deceleration (5)(6)(7)(8). The shearing force is transmitted to the sternum through the clavicles, the chin and the upper two ribs.…”

Manubriosternal Joint Dislocation: An Unusual Risk of Trampolining

“…Type I involves the posterior dislocation of the sternum in relation to the manubrium. It is caused by direct force on the sternum, such as a blow from an elbow, seen in basketball players (1,3,4). Type II is seen in hyperflexion of the thoracic spine with resultant compression of the anterior thorax.…”

Manubriosternal dislocation type II associated with thoracic spine fracture: What can we learn from this?

“…It is usually associated with flexion-compression upper thoracic spine fractures, and requires tremendous force. [4,12] The most common associated injuries are rib fractures, pulmonary contusion, pneumothorax and extremity fractures. One study showed an 18% incidence of myocardial contusion associated with sternal fractures.…”
