Wrist and hand injuries from gripping the steering wheel

How does a steering wheel injure the wrist and hand?

In the instant before a crash, most drivers grip the wheel hard and lock their arms. At impact, force travels from the wheel into the hands, through the wrists and up the arms. The wrist may bend back sharply. The thumb can be forced away from the hand. If the airbag deploys, it can push the hands and forearms aside with real force.

Passengers get similar injuries by bracing on the dashboard or the door handle.

What injuries are most common?

Wrist sprains are the most frequent. A sprain means a ligament is stretched or torn. The wrist has many small ligaments, and one of the most important is the scapholunate ligament, which holds two of the small wrist bones together. A significant tear there can change how the wrist moves over time.

Scaphoid fractures are a classic injury from landing on or bracing with an outstretched, bent-back hand. The scaphoid is a small bone at the base of the thumb side of the wrist. Its blood supply is limited, so a missed fracture can heal poorly.

Thumb ligament injuries happen when the thumb is bent back or out. The ulnar collateral ligament at the base of the thumb is often involved, which can make pinching and gripping weak.

Triangular fibrocartilage complex (TFCC) injuries affect the pinky side of the wrist. They cause pain with twisting motions like turning a doorknob or a key.

Distal radius fractures, breaks near the end of the forearm bone, happen with stronger forces.

Hand and finger fractures, tendon injuries and bruising from the airbag are also possible.

What symptoms should I watch for?

Get the wrist or hand examined if you have:

• Swelling or bruising that doesn't settle within a day or two
• Pain in the hollow at the base of the thumb, sometimes called the snuffbox
• Weak or painful grip
• Clicking, clunking or a feeling of something shifting in the wrist
• Pain on the pinky side with twisting
• Numbness or tingling in the fingers
• A finger or thumb that looks crooked or won't bend or straighten fully

Go to an emergency department for an obvious deformity, a cold or pale hand, or severe pain.

Why might an X-ray look normal at first?

Some fractures, especially of the scaphoid, don't show up on X-rays taken right after the injury. The crack may be too fine, or the bone may need to start healing before it's visible.

That's why doctors often treat suspected scaphoid fractures as fractures, with a splint, even when the first X-ray is normal. Follow-up X-rays in 10 to 14 days, or an MRI or CT sooner, can confirm or rule out the break.

Ligament and TFCC injuries never show on X-ray. MRI is the usual test when they're suspected.

How are these injuries evaluated?

An orthopedic specialist asks how you were holding the wheel, where it hurts, and what makes it worse. The exam includes pressing on specific bones, testing ligament stability, checking grip strength, and assessing nerves and circulation in the hand.

Imaging follows the exam: X-rays first in most cases, with MRI or CT if needed.

How are wrist and hand injuries treated?

Treatment depends on the specific injury:

• Mild sprains usually do well with a short period in a splint, then gradual return to use and hand therapy
• Scaphoid fractures that haven't shifted are usually treated in a cast for several weeks; displaced ones may need surgery
• Thumb ligament injuries are often managed with a splint, while complete tears with instability may need repair
• TFCC injuries are usually treated with bracing and therapy first
• Distal radius fractures may be treated with casting or surgery depending on alignment

Hand therapy helps restore motion and strength after immobilization.

How long does recovery take?

Mild sprains often feel better in two to six weeks. Fractures usually take six to 12 weeks to heal, and full strength can take longer. Ligament injuries vary widely.

How you use your hands at work shapes the plan. Someone who types all day and someone who uses heavy tools need different return plans. Tell your clinician exactly what your job involves.

Can a wrist injury cause problems later?

Some can. An unrecognized scaphoid fracture or significant ligament tear can lead to arthritis in the wrist years later. That's the main reason to get persistent wrist pain checked rather than waiting it out. Early diagnosis keeps more treatment options open.

Where can I get a wrist or hand injury checked in Texas?

SpineLUX orthopedics evaluates bone, joint, tendon and ligament injuries after accidents and coordinates imaging when your exam calls for it. Clinics serve Irving, Houston, San Antonio, Live Oak, McAllen and El Paso, with intake in English and Spanish. The Irving clinic is at 100 E Royal Ln, Suite 125.

What can I do at home while I wait for my visit?

Rest the wrist from heavy gripping and lifting. A simple brace from a pharmacy can help short term if it's comfortable. Ice for 15 minutes at a time can ease swelling. Take off rings early if your hand is swelling. Keep your fingers moving gently so they don't stiffen. If your fingers go numb, cold or pale, get seen right away.
