Posterior comminuted scapular fracture induced by a low-voltage electric shock

Scapular fractures caused by electric shock usually occur when victims fall over or are hit by other objects. As the direct result of electric shock, it is uncommon. In this report, we present a 44-year-old man who complained of severe left shoulder pain after suffering from an electric shock at the workplace. Physical examination revealed tenderness over his left suprascapular area with restricted left shoulder movements. Radiographic studies demonstrated comminuted fracture of posterior left scapula. After conservative management with an arm sling and swathe immobilization for 3 months, he made an uneventful recovery. In comparison to currents between 240 and 440 V reported in most published cases of scapular fractures, this patient who suffered scapular fracture after a 110-V current might be the most vulnerable case ever diagnosed. Because domestic electricity supplied with 100- to 240-V output is used mostly, scapular fractures should be suspected in patients with shoulder pain without direct injuries.
