Aetiology
A sprain of other specified part of the finger is caused by trauma, such as a sudden twist or a direct blow, that causes the ligaments of the finger to stretch or tear.
Diagnosis
A sprain of other specified part of the finger is usually diagnosed based on the patient’s history of the injury and physical examination. X-rays or other imaging tests may be used to confirm the diagnosis.
Differential diagnosis
Other conditions that may have similar symptoms and must be differentiated from a sprain of other specified part of the finger include fractures, tendon and joint injuries, and nerve injuries.
Treatment
Treatment of a sprain of other specified part of the finger usually involves rest, ice, compression, and elevation (known as the RICE protocol). Anti-inflammatory medications and splinting may also be used. Surgery may be necessary if there is extensive ligament damage.
Prognosis
The prognosis for a sprain of other specified part of the finger depends on the severity of the injury. If treated promptly and properly, the finger should heal completely and full function should be restored.
