Aetiology
A strain or sprain of the thumb is typically caused by a sudden force to the thumb, such as a fall or a forceful twist. It is often caused by overuse or repetitive movements.
Diagnosis
The diagnosis of a strain or sprain of the thumb is typically made through a physical exam. The doctor will check for tenderness and swelling, as well as any other signs of injury. X-rays may be taken to rule out any fractures.
Differential diagnosis
A strain or sprain of the thumb can be easily confused with a fracture or dislocation of the thumb. It is important for the doctor to rule out a fracture or dislocation as these require more aggressive treatment.
Treatment
Treatment for a strain or sprain of the thumb typically involves rest and immobilization of the thumb. Ice, elevation, and over-the-counter pain medications can help to reduce pain and swelling. More severe cases may need physical therapy or a splint or cast to help the thumb heal properly.
Prognosis
The prognosis for a strain or sprain of the thumb is usually good. The thumb should heal in 4-6 weeks with proper rest and treatment. In some cases, it may take longer for the thumb to heal.
