CPD Questionnaire

摘要

The mechanism of this stress fracture may be due to sudden forward angulations at the thoracic spine and violent protraction of the shoulders, stressing the sternum via the clavicles. We postulate that the forward flexion on the spine during the repeated tumbles and the motion on assuming the standing position contributed to the injury. The dynamic movement of sudden standing stresses the ribs and the maldistribution of forces across the scalene muscles and pectoralis major, impact on the sternum, resulting in the sternal stress fracture.
