What are the signs that indicate you may have damaged a tendon in your hand?

Tendon damage in your hand can manifest through distinct limitations in finger movement. If the extensor tendons are affected, you may find it impossible to straighten one or more fingers, while damage to the flexor tendons can prevent you from bending them. In addition to these mobility issues, you might experience pain and noticeable swelling in the affected areas, signaling the need for medical attention. Recognizing these symptoms early can help in seeking appropriate treatment and preventing further complications.

What is the most prevalent hand tendon injury?

Mallet Finger is recognized as the most prevalent closed tendon injury affecting the hand. It typically occurs when there is forced flexion of the extended distal interphalangeal (DIP) joint, often seen in sports activities like catching a ball. This sudden trauma can lead to significant pain and disruption in normal finger function.

Individuals with Mallet Finger often experience intense discomfort at the back of the DIP joint and find themselves unable to actively extend it. This condition not only impairs hand movement but can also impact daily activities, making prompt diagnosis and treatment essential for restoring full finger function.

Do hand tendons repair themselves naturally?

Tendons in the hand are crítico for movement and functionality, but when they are cut, they do not have the ability to heal on their own. The natural tension in a tendon often leads to the cut ends separating, sometimes by significant distances. This separation not only complicates the healing process but also means that without intervention, the chances of recovering lost movement are virtually nonexistent.

Surgical repair is essential for restoring the integrity and functionality of a cut tendon. By bringing the ends of the tendon back together, surgery facilitates the healing process and allows for the possibility of regaining movement. Timely intervention is critical, as it can significantly improve outcomes and enhance the ability to return to daily activities.
