A 60-Year-Old Woman Fell Down the Stairs and Was Admitted

A 60-year-old woman fell down the stairs and was admitted to the emergency department with severe right shoulder pain. On examination, the patient was sitting up with her right arm by her side and her right elbow joint supported by her left hand. Inspection of the right shoulder showed loss of the normal rounded curvature and evidence of a slight swelling below the right clavicle. Any attempt at active or passive movement of the shoulder joint was stopped by severe pain in the shoulder. A diagnosis of dislocation of the right shoulder joint was made.
-The following statements concerning this patient are consistent with the diagnosis except which?

A) This patient had a subcoracoid dislocation of the right shoulder joint.
B) The head of the humerus was dislocated downward through the weakest part of the capsule of the joint.
C) The pull of the pectoralis major and subscapularis muscles had displaced the upper end of the humerus medially.
D) The greater tuberosity of the humerus no longer displaced the deltoid muscle laterally, and the curve of the shoulder was lost.
E) The integrity of the axillary nerve should always be tested by touching the skin over the upper half of the deltoid muscle.
