Correct Answer: glenoid labrum tear test
among the given choices, the glenoid labrum tear test is the specific orthopedic examination where the patient is required to be in a supine position. this position involves the patient lying on their back, which is essential for the proper execution of this test. the supine position allows the healthcare provider to manipulate the shoulder effectively to assess the integrity of the glenoid labrum.
the glenoid labrum tear test is designed to detect tears or lesions in the glenoid labrum of the shoulder. the labrum is a fibrocartilaginous structure that surrounds and deepens the glenoid cavity, thus stabilizing the shoulder joint. during the test, the examiner typically applies pressure or rotates the arm to provoke a response that could indicate a tear. a common sign that the test is positive is the presence of a "clunk" or "grinding" sound, which suggests that there might be an irregularity or tear in the labrum.
other tests mentioned such as yergason’s test, roos test, and the hawkins-kennedy impingement test, involve different patient positions and focus on other aspects of the shoulder. for instance, yergason’s test is performed with the patient sitting or standing and evaluates the biceps tendon stability. roos test, also known as the “elevated arm stress test,” is conducted with the patient in a seated or standing position with arms elevated, primarily assessing for thoracic outlet syndrome. the hawkins-kennedy impingement test, which checks for shoulder impingement, requires the patient to be seated or standing while the examiner internally rotates the patient’s shoulder.
thus, when comparing these tests, it is clear why the glenoid labrum tear test specifically requires the supine position. this position is crucial for accessing and effectively evaluating the glenoid labrum for potential injuries, which the other tests, with their different focuses and required positions, do not assess.
