Proximal humerus fracture associated with delayed axillary nerve injury

Abstract

Axillary nerve injury is the most common complication in humerus fracture. The symptoms that are caused by affecting axillary nerve vary according to the structures involved such as sensory disturbance and weakness of muscles, e.g., three parts of deltoid and teres muscles in an affected limb. The severity of injury is classified in demyelinating and axonal lesions, which usually occurs at the onset of fracture. The author reports a case of humerus fracture with delayed axonal lesion of axillary nerve result from inadvertent traction.
