Aetiology
Other specified injury of extensor muscle, fascia or tendon of other finger at forearm level is caused by a direct or indirect trauma, such as a fall, a blow, or a forceful movement. It can also be caused by repetitive motion injuries or overuse.
Diagnosis
Diagnosis is usually done through physical examination and imaging tests such as X-rays, CT scans, or MRIs.
Differential diagnosis
Differential diagnosis includes other conditions that may cause similar symptoms, such as tendinitis, carpal tunnel syndrome, and cubital tunnel syndrome.
Treatment
Treatment depends on the severity of the injury and may include rest, ice, and elevation; immobilization of the injured finger; physical therapy; medications; and, in severe cases, surgery.
Prognosis
Prognosis is generally good with treatment, although recovery may take several months. In severe cases, surgery may be necessary and can lead to long-term disability.
