Wrist Ligament Injuries

Introduction

The wrist is a remarkable joint that plays a vital role in the intricate movements of the hand. It allows us to perform everyday tasks, from typing to playing sports. Unfortunately, a wrist injury can lead to significant pain and disability, affecting your quality of life.

What Structures Can Get Injured in the Wrist?

The wrist comprises eight small bones known as carpal bones. These bones form connections with the forearm bones—the radius and ulna—and the hand bones, called metacarpals. The complex arrangement of these bones, along with ligaments that hold them together, enables the wrist to flex, extend, and move sideways.

When ligaments are injured, they disrupt the normal function of the wrist, leading to pain and potential long-term issues such as arthritis.

How Do Wrist Ligament Injuries Occur?

Most wrist injuries happen when you fall on an outstretched hand. Depending on the force of the fall and the position of the wrist, this can result in either fractures or ligament injuries. Ignoring ligament injuries can lead to joint instability, which may accelerate cartilage wear and lead to early arthritis.

How Do Wrist Ligament Injuries Present?

If you experience a wrist injury, you might notice:

  • Pain and swelling in and around the wrist
  • Bruising or discoloration (ecchymosis)
  • A clicking or snapping sensation due to joint instability
  • A weakened grip in your hand
  • In advanced cases, rest pain resulting from osteoarthritis

How Are Ligament Injuries Diagnosed?

Diagnosing wrist ligament injuries begins with a thorough medical history and clinical examination to identify the specific ligaments affected. X-rays can help rule out fractures and osteoarthritis but won’t reveal ligament damage. For detailed assessment, Magnetic Resonance Imaging (MRI) is invaluable, as it can visualize ligaments, cartilage, and other soft tissues. If there’s still uncertainty, wrist arthroscopy can provide clarity and allow for potential repair during the same procedure.

What Is the Treatment for Wrist Ligament Injuries?

Treatment options vary depending on whether the injury is acute (recent) or chronic (ongoing).

Nonsurgical Treatment

For partial ligament injuries, a cast or splint may be prescribed for three to six weeks to facilitate healing.

Surgical Treatment

If the ligaments are completely torn or the bones are misaligned, surgery may be necessary. The surgical approach can involve repairing or reconstructing the ligaments or pinning the bones together to ensure proper alignment while healing occurs.

Post-Surgery Care

After surgery, you may need to wear a bandage or brace for several days to weeks. Your recovery will include specific exercises to maintain wrist flexibility and strengthen the forearm, wrist, and hand muscles.

Case Example

Meet Sarah: Sarah is an active 30-year-old who loves playing tennis. One day, she took a fall while trying to make a quick shot, landing on her outstretched hand. Initially, she felt a sharp pain in her wrist, followed by swelling and bruising. After a thorough examination and an MRI, Sarah was diagnosed with a torn ligament in her wrist, specifically a scapholunate ligament injury.

Her doctor recommended a non-surgical approach, placing her wrist in a splint for four weeks. After the splint came off, Sarah began physical therapy to regain strength and mobility. Although she was eager to return to the tennis court, she diligently followed her rehabilitation plan, which helped her recover effectively and safely return to her favorite sport.
