Aetiology
Strains and sprains of the extensor muscles, fascia or tendons of the fingers at the forearm level are typically caused by a sudden or forceful movement of the affected area. This can be due to an acute trauma, such as a fall, or from repetitive strain from activities such as typing or gripping small objects.
Diagnosis
The diagnosis of a strain or sprain of the extensor muscles, fascia or tendons of the fingers at the forearm level is typically made based on a physical examination. This exam may include range of motion tests, strength tests, palpation, and imaging studies such as x-rays or MRI scans.
Differential diagnosis
Other conditions that can cause similar symptoms include tendinitis, tenosynovitis, nerve entrapment, and fractures.
Treatment
Treatment of a strain or sprain of the extensor muscles, fascia or tendons of the fingers at the forearm level typically includes rest, ice, compression, and elevation (RICE). Other treatment options may include physical therapy, medications, bracing, and in some cases, surgery.
Prognosis
With prompt diagnosis and treatment, most patients with a strain or sprain of the extensor muscles, fascia or tendons of the fingers at the forearm level can make a full recovery. However, in some cases, the injury may lead to long-term or permanent damage.
