Frozen shoulder development secondary to proximal humerus fracture and supraspinatus tendon tear following electrical injury

Musculoskeletal injury incidence occurring as a result of low voltage electrical accidents is extremely rare. In the present paper, we report 2 cases of low voltage electrical injuries with frozen shoulder development secondary to proximal humerus fracture and supraspinatus tendon tear. Magnetic resonance imaging, taken due to persistence of shoulder pain and reduction of shoulder joint mobility in cases monitored because of proximal humerus fracture associated with electrical injury, revealed a tear of supraspinatus tendon. Moreover, frozen shoulder status was clinically established in both of the cases. The cases were treated with an appropriate physical therapy and rehabilitation program. Supraspinatus tendon tears accompanying proximal humerus fractures should not be overlooked in low voltage electrical injuries and development of frozen shoulder should be avoided by applying the proper physical therapy and rehabilitation program.
