Aetiology
Injury of the extensor muscles, fascia, and tendons of other fingers at wrist or hand level can be caused by repetitive motion and overuse, such as typing, playing a musical instrument, or sports activities. Other possible causes include direct trauma to the area, such as blunt force, overstretching, or a fall on an outstretched hand.
Diagnosis
Diagnosis of injury to the extensor muscles, fascia, or tendons of other fingers at wrist or hand level is usually made through a physical examination and imaging studies such as X-ray, CT scan, or MRI. The physical exam will assess for pain, swelling, tenderness, and range of motion.
Differential diagnosis
Differential diagnoses for injury to the extensor muscles, fascia, or tendons of other fingers at wrist or hand level include tendonitis, tenosynovitis, carpal tunnel syndrome, arthritis, and ganglion cysts.
Treatment
Treatment for injury to the extensor muscles, fascia, or tendons of other fingers at wrist or hand level typically consists of rest, physical therapy, anti-inflammatory medications, and braces or splints. In cases of more severe injury, surgical intervention may be necessary.
Prognosis
The prognosis for injury to the extensor muscles, fascia, or tendons of other fingers at wrist or hand level is generally good with proper rest, physical therapy, and other treatments. However, it may take several weeks or months to fully recover.
