To explain the mechanism of trauma from falls onto an outstretched hand (FOOSH) To review the imaging patterns of the various cases of the injuries from this mechanism in the upper extremities.

A fall onto outstretched hand is a common trauma. This mechanism causes injuries to various parts of upper extremity, from shoulder to hand. In the emergency department, it is necessary to understand various kinds of injuries from this mechanism to promptly and appropriately manage for patients.

Imaging pattern according to the body part of upper extremity -- Radiography, CT, or MRI imaging findings. 1. Shoulder/upper arm 1) Clavicle fracture (Fig 1) -Mechanism of injury: * direct blow on the point of shoulder is the commonest mechanism * usually medium to high energy, with falling on to outstretched arm 2)Proximal humeralfracture (Fig 2) - Mechanism of injury: * after both high- and low-energy trauma * particularly characteristic of falls in elderly women with osteoporosis 3)Anterior shoulder dislocation (Fig 3) - Mechanism of...

A fall onto an outstretched hand (FOOSH) is a common mechanism for upper extremity injury. Radiography, CT or MR imaging plays an important role in the assessment of patients with upper extremity injury. Knowledge of imaging patterns provides a framework for understanding spectrum of this injury
