What is a Sulcus Test?

"Sulcus" refers to a crevice, groove, furrow, or fissure found in various body parts. These sulci can be present in different organs and structures, such as the brain, heart, bones, etc. In biological morphology and anatomy, a sulcus is a depression or indentation in a surface, which can serve as a natural division or separation between different parts of an organ or structure.

The is a commonly used orthopedic examination test designed to assess inferior instability in the shoulder's glenohumeral joint. This examination focuses on the glenohumeral joint capsule and the ligamentous structures, particularly the superior glenohumeral and coracohumeral ligaments.

The test is typically conducted with the subject seated and the arm to be evaluated in a relaxed position. One of the examiner's hands stabilizes the shoulder girdle on the tested side while the other hand firmly grasps the elbow of the tested arm. The movement involves pulling down on the subject's elbow.

A positive outcome of the Sulcus Sign test is indicated by the noticeable inferior movement of the arm relative to the shoulder, often accompanied by a visible 'sulcus' or 'step-off deformity' between the acromion and the humeral head. While pain and apprehension may or may not be present, a positive result suggests the presence of inferior or multidirectional instability (MDI) in the shoulder.

How Does it Work?

Orthopedic professionals can use our Printable Sulcus Test to evaluate inferior instability in the shoulder's glenohumeral joint. Here's a breakdown of its procedure:

Step One: Introduce the test to clients

The orthopedic professional introduces the Sulcus Test to the patient, providing an overview of its purpose and ensuring the patient understands that there are no right or wrong outcomes. The patient is informed that the test involves a specific arm movement.

Step Two: Help the client get the right starting position

The patient is seated, and the arm to be tested is allowed to relax. One of the examiner's hands stabilizes the shoulder girdle on the evaluated side while the other securely holds the patient's elbow.

Step Three: Initiate the test

The examiner initiates the test by gently pulling the patient's elbow down, creating a specific movement at the glenohumeral joint.

Step Four: Decode positive result

A positive result is indicated if there is noticeable downward movement of the arm with the shoulder joint, accompanied by a visible 'sulcus' or a distinct step-off between the acromion and the humeral head. While discomfort or apprehension may or may not be experienced, a favorable outcome suggests the presence of inferior or multidirectional instability (MDI) in the shoulder.

Sulcus Tests Example (sample)

The Sulcus Tests PDF involves a precise procedure to assess inferior shoulder joint instability. With the patient comfortably seated, the examiner initiates the test by firmly grasping the patient's elbow and gently pulling downward. 

A positive result is observed when the arm exhibits downward movement relative to the shoulder, accompanied by a visible 'sulcus' or step-off between the acromion and the humeral head. This outcome suggests potential inferior or multidirectional instability, informing further evaluation and treatment decisions. 

The Sulcus Test's accuracy ensures dependable diagnostic insights, assisting orthopedic professionals in delivering targeted care for shoulder instability. Through this test, clinicians gain a nuanced understanding of the joint's condition, fostering patient trust and effective management. The Sulcus Test template stands as a vital tool in the journey to restore shoulder stability.

Research & Evidence

The term "sulcus," referring to a groove or indentation, has contributed to understanding anatomical structures, including joints, bones, and their functionalities. While the direct historical narrative of the term in medical literature might be less prominent, the broader history of anatomical discovery lays the foundation for the assessment of shoulder instability using the Sulcus Test.

Throughout history, medical practitioners have benefited from understanding anatomical landmarks and variations. The concept of the "sulcus" has helped guide medical procedures involving the shoulder joint.

The Sulcus Test has emerged as a valuable tool for diagnosing shoulder instability in modern medical practice. This test involves assessing the presence of a visible gap or sulcus between the acromion and the humeral head during specific movements. This phenomenon indicates inferior or multidirectional instability. A combination informs the development of this test of historical anatomical knowledge and contemporary clinical research.

Evidence from research studies and advancements in imaging techniques continue to enrich our understanding of this phenomenon, contributing to improved medical procedures and better patient care in orthopedics.
