A strain or sprain of the intrinsic muscles, fascia or tendons of a finger at the wrist or hand level is usually caused by overuse, repetitive movements, or sudden trauma to the area.
Diagnosis is typically made based on the patient’s history, a physical examination, and imaging studies such as X-rays or MRI.
Differential diagnosis may include other conditions such as carpal tunnel syndrome, tenosynovitis, or arthritis.
Treatment for a strain or sprain of the intrinsic muscles, fascia or tendons of a finger at the wrist or hand level usually includes rest, ice, compression, and elevation (RICE). Other treatments may include physical therapy, braces, or medications such as anti-inflammatories.
The prognosis is generally good with appropriate treatment. Recovery time may vary depending on the severity of the injury.
