The same 68-year-old male patient from the previous as been assessed.
For each of the following findings, indicate whether they are generally associated with a rotator cuff injury or a humeral fracture.

Choice A rationale

Decreased range of motion is generally associated with a rotator cuff injury. This is because the rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of the upper arm bone firmly within the shallow socket of the shoulder. When these muscles or tendons are injured, it can limit the shoulder’s range of motion.

Choice B rationale

Pain with movement can be a symptom of both a rotator cuff injury and a humeral fracture. Both conditions involve structures that are integral to the movement of the arm, and damage to these structures can cause pain when they are moved or put under strain.

Choice C rationale

Reduced strength in the left upper extremity is more commonly associated with a rotator cuff injury. The rotator cuff is responsible for the stability of the shoulder joint and enables the arm to lift and rotate. An injury to the rotator cuff can therefore lead to a reduction in the strength of the arm.

Choice D rationale

Reduced pulse distal to the injury is more commonly associated with a humeral fracture. This is because a fracture to the humerus could potentially damage the blood vessels running along the bone, leading to a reduced pulse further down the arm.

Choice E rationale

Coolness of the skin is more commonly associated with a humeral fracture. This could be due to damage to the blood vessels, leading to reduced blood flow and therefore a lower skin temperature.
