Glenohumeral joint instability refers to the inability of the shoulder joint to maintain its normal anatomical alignment during movement, leading to increased risk of dislocation or subluxation. This condition can result from traumatic injury, repetitive strain, or congenital factors, significantly impacting an individual's range of motion and quality of life.

Glenohumeral Joint Instability

The shoulder joint, also known as the glenohumeral joint, is a ball-and-socket joint that allows for a wide range of motion but is inherently less stable compared to other joints. Its stability is primarily maintained by a combination of muscles, tendons, and ligaments, making it susceptible to injuries such as dislocations and rotator cuff tears.

Normal anatomical alignment

Movement is when something changes its place or position. It's like when you walk, run, or jump from one spot to another.

Risk of dislocation

Risk of subluxation

A traumatic injury is a physical injury or wound caused by an external force, which can range from minor to life-threatening. It often requires immediate medical attention and can have long-term physical and psychological effects on the individual.

Traumatic Injury

Repetitive Strain

Congenital factors

Range of motion (ROM) refers to the full movement potential of a joint, usually measured in degrees of a circle. It is crucial for assessing joint function, diagnosing injuries, and planning rehabilitation or exercise programs to improve flexibility and prevent injury.

Range Of Motion

Quality of life is a multi-dimensional concept that encompasses subjective and objective evaluations of an individual's overall well-being and satisfaction with life. It is influenced by various factors including physical health, psychological state, level of independence, social relationships, and personal beliefs.
