Electricity can cause skeletal muscles to undergo tetanic contractions, which can be strong enough to break bone, especially if the bone has a weakness.
Scenario 1:
(1) A pediatric patient with an unfused epiphyseal plate.
(2) Exposure of muscles that cross the unfused plate to electricity.
(3) Sufficient tetanic activity to cause a fracture.
Scenario 2:
(1) A muscular adult.
(2) Contractions across the scapula, femoral neck or other sites in the proximal appendicular skeleton.
Scenario 3:
(1) A patient with weakened bone (severe osteoporosis, bone tumor, etc).
(2) Contractions across the scapula, femoral neck or other sites in the proximal appendicular skeleton.
Differential diagnosis:
(1) fall-related fracture
