GLENOIDAL LABRUM Meaning and
Definition
-
The glenoidal labrum is a cartilaginous structure that surrounds the glenoid fossa, which is a shallow depression in the scapula bone of the shoulder joint. It serves as a vital component of the glenohumeral joint, providing stability and support to the articulation between the humerus bone and the scapula.
The glenoidal labrum is composed of fibrocartilaginous tissue and is shaped like a horseshoe or a ring. It is continuous with the joint capsule and is firmly attached to the rim of the glenoid fossa. Its main function is to deepen the socket of the glenoid fossa, increasing the stability of the joint and acting as a shock absorber during movements of the shoulder.
The glenoidal labrum also serves as an attachment site for several structures, including the long head of the biceps tendon and several ligaments that further enhance stability. It provides additional surface area for the shoulder joint, allowing for greater contact between the glenoid fossa and the humerus bone.
Damage or injury to the glenoidal labrum can occur due to trauma, repetitive overuse, or degenerative conditions. This can lead to a range of symptoms, including pain, instability, and limited range of motion in the shoulder joint. Treatment options may include physical therapy, medications, or in severe cases, surgical repair or reconstruction of the glenoidal labrum.

Etymology of GLENOIDAL LABRUM
The term "glenoidal labrum" is derived from two sources:
1. Glenoidal: The word "glenoidal" comes from the Greek term "glenos" which means "socket" or "cavity". It is used in medical terminology to refer to structures or areas that resemble or relate to a socket-shaped cavity. In this context, "glenoidal" describes the labrum's location and structure within the glenoid cavity in the shoulder joint.
2. Labrum: The word "labrum" originates from Latin, where it means "lip". It is commonly used in anatomy to refer to a ring or lip of fibrocartilage that surrounds the edge of a joint socket. The labrum helps to deepen the joint socket, adding stability and improving the fit between the bones of the joint.
