Tendon Injuries
Diagnosis of Extensor Tendon Injuries
Diagnosis of extensor tendon injuries typically involves a combination of physical examination and imaging studies. Physicians start by assessing the patient’s history, including the mechanism of injury and symptoms experienced. During the physical exam, they visually inspect the hand and fingers for signs of swelling, bruising, or lacerations. The ability to extend the fingers and thumb is evaluated to identify any loss of function, while gentle palpation of the injured area assesses pain and tenderness. Imaging tests, such as X-rays, may be ordered to rule out fractures or evaluate tendon integrity, and in some cases, an MRI may be necessary for a detailed view of the tendons and surrounding structures. Early and accurate diagnosis is crucial for effective treatment and recovery.
Treatment of Extensor Tendon Injuries
Treatment of extensor tendon injuries primarily focuses on immobilization and, in some cases, surgical intervention. Tears caused by jamming injuries are typically treated with splints that hold the tendon in place. These splints should be worn continuously for about eight to twelve weeks, with longer periods occasionally required. A provider will apply the splint correctly and provide guidance on how long to wear it.
For cuts in the tendon, stitches may be necessary, and in certain cases, a pin may be placed through the bone to serve as an internal splint. Surgery may be needed to free scar tissue in cases of significant motion loss. After initial treatment, hand therapy is often required to restore motion.
In most instances of mallet finger, splinting is effective even if the tendon is completely torn, as the ends can be aligned through immobilization. However, in some cases, surgery may be necessary to repair or realign the tendon or associated bone fragments, usually performed in an outpatient setting without general anesthesia.
Extensor Tendon Injuries FAQ
Can Extensor Tendon injuries cause elbow pain?
Yes, an extensor tendon issue can cause elbow pain. This may occur due to referred pain from the wrist or forearm, or because the extensor muscles that extend the wrist and fingers originate near the elbow. If the tendons are injured or inflamed, it can lead to discomfort in the elbow area as well. If you’re experiencing persistent pain, it’s advisable to consult a healthcare professional.
How long does Extensor Tendon injuries take to heal?
The healing time for an extensor tendon injury can vary based on the severity of the injury. Mild cases, such as tendonitis or minor strains, may heal within a few weeks with rest and rehabilitation. More severe injuries, like partial or complete tears, can take several weeks to months to heal, especially if surgery is required. It’s important to follow a medical professional’s advice for the best recovery outcome.
Where are Extensor Tendons located?
The extensor tendons are located in the back of the forearm and run along the wrist and fingers. They attach the muscles in the forearm to the bones in the fingers and wrist, enabling movements like extending the fingers and wrist.
