liðflötum

liðflötum is an Icelandic term that translates to "dislocated shoulder" in English. It refers to a condition where the head of the upper arm bone, the humerus, is pulled out of its socket, the glenoid cavity, which is part of the shoulder blade. This injury can be complete or partial, with a complete dislocation meaning the bones are fully separated and a partial dislocation, also known as a subluxation, where they remain partially in contact.

The shoulder joint is the most mobile joint in the human body, allowing for a wide range of motion. This extensive mobility, however, makes it more susceptible to dislocation. Common causes of liðflötum include direct trauma, such as a fall onto an outstretched arm or a blow to the shoulder, and forceful twisting or lifting motions. Sports activities, particularly those involving contact or overhead movements like rugby, football, or swimming, are frequent contributors to shoulder dislocations.

Symptoms of liðflötum typically include intense pain in the shoulder, an inability to move the arm, and a visible deformity where the shoulder appears out of place. Swelling and bruising may also be present. Medical attention is usually required to diagnose and treat a dislocated shoulder. Treatment often involves reducing the dislocation, which means carefully maneuvering the humerus back into its socket. This procedure is usually performed by a healthcare professional. Following reduction, the shoulder is often immobilized with a sling to allow the surrounding tissues to heal. Physical therapy is commonly recommended to regain strength, flexibility, and stability in the shoulder joint and to prevent future dislocations. Recurrent dislocations can occur, especially if the initial injury was severe or if the stabilizing tissues are significantly damaged.
