Aetiology
Sprain of other specified part of thumb is an injury to the ligaments of the thumb. This is usually caused by direct trauma to the thumb, such as a fall or a blow to the thumb, or by overstretching the thumb.
Diagnosis
Sprain of other specified part of thumb is usually diagnosed based on a physical examination and a patient history. The healthcare provider may also order imaging tests, such as an X-ray, to check for fractures or other injuries.
Differential diagnosis
Other conditions that may be confused with a sprain of the thumb include a fracture, tendinitis, or a ligament tear.
Treatment
Treatment for a sprain of other specified part of thumb typically includes rest, ice, compression, and elevation of the affected thumb. Nonsteroidal anti-inflammatory drugs, or NSAIDs, may be used to reduce pain and swelling. Physical therapy may also be recommended to help restore range of motion and strength to the thumb.
Prognosis
The prognosis for a sprain of other specified part of thumb is usually good if the injury is treated properly. Most patients will recover with no long-term complications. However, if the injury is not treated properly or if it is a more severe injury, complications such as chronic pain or limited range of motion may occur.
