Glenohumeral instability refers to the inability to maintain the humeral head centered within the glenoid fossa, often leading to pain and dysfunction in the shoulder joint. It can result from traumatic injury, repetitive strain, or congenital factors, and may require physical therapy or surgical intervention for stabilization.

Glenohumeral Instability

The humeral head is the rounded, proximal end of the humerus that articulates with the glenoid cavity of the scapula, forming the shoulder joint. Its shape and structure are crucial for the wide range of motion and stability required by the shoulder, making it a focal point in orthopedic studies and treatments related to shoulder injuries and disorders.

Humeral Head

Glenoid Fossa

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.

Shoulder Joint

Pain and dysfunction

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

Physical therapy is a healthcare profession focused on the assessment, diagnosis, and treatment of physical impairments, disabilities, and pain through various therapeutic interventions. It aims to restore, maintain, and promote optimal physical function, movement, and overall health and wellness in individuals across their lifespan.

Physical Therapy

Surgical intervention involves the manual and instrumental techniques performed to treat a pathological condition, improve bodily function, or enhance appearance. It requires careful consideration of risks and benefits, informed consent, and often involves a multidisciplinary team for optimal patient outcomes.

Surgical Intervention

Joint stabilization refers to the process of maintaining or restoring the structural integrity and functional performance of a joint through various means such as muscle strengthening, proprioceptive training, or external support. It is crucial for preventing injuries, enhancing athletic performance, and managing conditions like arthritis or post-surgical recovery.
