Traumatic tendon injuries of the hand and wrist are common, and this article outlines the causes, symptoms, and treatments.
Traumatic tendon injuries of the hand and wrist
Tendons, muscles and bones work together to enable a full range of motion in our arms and hands. Trauma to the tendon prevents us from fully extending the wrist or finger. Tendon injuries such as cuts (tears) and severe tendon tears require immediate treatment to prevent permanent damage.
Tendons attach muscles to bones. In the forearm, there are several tendons called "flexor tendons" that connect the muscles of the forearm to the bones of the fingers. Deep cuts to the fingers, palm, or forearm can damage these flexor tendons and surrounding nerve fibers. The tendon can also be stretched too far, causing a partial or complete tear. In some cases, the tendon can break away completely from the bone (avulsion fracture).
Causes of Traumatic Tendon Injury in the Hand and Wrist
Flexor tendon and nerve injuries in the forearm and hand are almost always caused by sudden trauma. Reasons include:
- contact sports
- severe tendon degeneration
- Traumatic tendon injury symptoms in the hand and wrist
Symptoms of traumatic tendon injury include:
Inability to bend finger joints
- Numbness or tingling in the fingertips
- Pain when stretching fingers
- Wrist traumatic tendon injury treatment
Treatment for tendon injuries will depend on the severity of the trauma. A partially cut or torn tendon can be treated non-surgically. A complete tear requires surgery to stitch the ends of the tendon together. Nerve damage can also be repaired with surgery. After surgery, you may need:
- physical therapy
- Risk factors for traumatic tendon injuries in the hand and wrist
Certain risk factors can increase your chances of sustaining tendon or nerve damage. These include:
have an underlying medical condition such as rheumatoid arthritis
- high-risk activities such as rock climbing or wrestling
- Use sharp tools or machinery
- Prevention of Wrist Traumatic Tendon Injuryk
Here are some tips to reduce your risk of injury:
Sports Injuries Prevention - Avoid high-intensity exercise that can lead to traumatic tendon injuries.
Take Safety Precautions - Wear protective gloves if you must handle sharp or heavy tools and machinery.
