Thumb Sprain: Causes, Symptoms, and Treatment Options
A sprain of the metacarpophalangeal joint of the thumb is a common injury that occurs when the ligaments connecting the thumb bone to the hand bone are stretched or torn. This can happen due to a sudden twisting or stretching motion, such as during a fall or while participating in sports activities.
The symptoms of this condition may include pain, swelling, bruising, and difficulty moving the thumb. The affected area may also be tender to touch.
If left untreated, a sprain of the metacarpophalangeal joint of the thumb can lead to long-term instability and weakness in the thumb, making it difficult to perform everyday tasks that require gripping or pinching.
Treatment typically involves resting the thumb, applying ice to reduce swelling, and immobilizing the joint with a splint or brace. Physical therapy exercises may also be recommended to help regain strength and range of motion. In more severe cases, surgery may be necessary to repair the damaged ligaments. Early diagnosis and appropriate treatment can significantly improve outcomes and prevent further complications.
