Rad Procedures: Upper Limb Pt 2

Explanation
The correct answer is "neutral" because when the patient is resting their palm-hand against their thigh, the shoulder joint is in a neutral position. In this position, the shoulder is neither internally rotated nor externally rotated. The arm is relaxed and hanging naturally by the side of the body, with the palm facing the thigh. This position allows for optimal resting and minimizes strain on the shoulder joint.

Explanation
In the given scenario, the patient is resting the back of their hand against their thigh. This position indicates internal rotation of the shoulder joint. Internal rotation refers to the movement of the arm or shoulder towards the midline of the body. So, the correct answer in this case is internal.

Explanation
The correct answer is "external." In the given scenario, the patient is extending their hand out and away from their body. This movement involves the rotation of the shoulder joint externally, as the hand moves away from the midline of the body. Internal rotation would be the opposite movement, where the hand moves towards the midline. Neutral position refers to the absence of any rotation.

Explanation
The correct answer is 1 in inferior to clavicle or at coracoid process. This means that the CR (central ray) should be positioned either below the clavicle or at the coracoid process when performing a shoulder anterior-posterior (AP) projection. This is the correct positioning for obtaining a clear image of the shoulder joint and surrounding structures.

Explanation
A transthoracic lateral projection can be performed instead of a regular shoulder projection if a patient is unable to abduct or raise their injured arm. This projection allows for a clear visualization of the shoulder joint and surrounding structures by positioning the patient in a lateral position and directing the x-ray beam horizontally through the shoulder. This projection helps to assess any fractures, dislocations, or other abnormalities in the shoulder joint.

Explanation
The statement is false because the scapular Y view cannot be used in place of an axial projection. The scapular Y view is a specific radiographic projection used to visualize the scapula and its articulations, while an axial projection is a different radiographic technique used to visualize structures along the axis of the body. Therefore, the scapular Y view cannot substitute for an axial projection.
