Do I have a Broken or Sprained Wrist?

How does a broken or sprained wrist happen? Rushing around, trying to do too many things at once, we have tripped and fallen. Usually it’s fine. We brush ourselves off and keep going. However, the first thing we usually do when we fall is try to catch ourselves by putting our hands out. Our wrists are not meant to take that kind of impact, though, and often the force of a fall can cause damage to wrists.

Wrist pain caused by a fall might be serious or it might not. How do we know if we have a broken or sprained wrist? Sometimes it is hard to tell.

In today’s post, I would like to discuss wrist fractures by clarifying what a wrist fracture is, how to differentiate between a fracture and a sprain, and explain how they are treated.

Understanding the Wrist

The wrist is a complex joint called an ellipsoid type synovial joint, which means that the joint is made of oval shaped wrist bones (carpals) that move on, or articulate with, a concave reciprocal bone, which is either the forearm bone (radius) or the other carpal bones.

This unique structure allows for movement along two planes front to back and side to side. These movements are controlled by the muscles of the forearm.

The wrist is made up of the ends of the radius and ulna, 8 carpal bones, and the bases of the 5 metacarpal bones.

Types of wrist fractures (or breaks)

A fracture and a break are considered the same thing.  A wrist fracture is when one or more bones in the wrist break. Below are the most common type of wrist fractures:

Broken or sprained wrist scaphoid

The scaphoid carpal bone is just below the base of thumb and can be broken when you fall on an outstretched palm and wrist. This bone is the second most common one to be fractured. An unrecognized fracture of the scaphoid bone is often mistaken for a wrist sprain as the swelling is usually only located to the small area where the bone is, and motion of the wrist can be maintained. Other carpal bones can be fractures but are much less common.

The Difference Between a Broken or Sprained Wrist

A sprain involves the ligaments that connect the bones at the joint.  It can be difficult to tell the difference between a fracture and a sprain. You should not assume that the degree of pain determines the specific problem.

Although it would seem that a sprain would hurt less than a fracture, this is not always the case. Sprains can often be extremely painful, where fractures may sometimes hurt less.  There are also different degrees of sprains from mild to severe.

A broken or sprained wrist may have many of the same symptoms:

  • Swelling in your wrist or hand
  • Pain, especially when you move your wrist
  • Difficulty picking up objects
  • Bruising
  • Limited range of motion

However, if you’ve fractured your wrist, there are a few symptoms that go beyond sprains. There may be a deformity in the wrist and bone pushing against the skin or sometimes puncturing it. When you fall and hurt your wrists, you might hear a snap or pop and your wrist will usually swell immediately and worsen, even when treated with ice.

The best way to know for certain if your wrist is fractured or sprained is to see a hand surgery specialist. They can do a thorough assessment and diagnose what is causing your pain.

"Many wrist fractures do not require surgery, and can be adequately treated in a cast or brace. "Brandon P. Donnelly, MD

Treatment for a Broken Wrist

If you believe you’ve sprained your wrist, you should treat it with ice, stabilize it with a brace or splint, and keep it elevated. Nevertheless, if you’re concerned that you may have fractured it or the pain and swelling intensifies, apply ice, and then see a hand specialist as soon as possible.

Many wrist fractures do not require surgery, and can adequately treated in a cast or brace.  Sometimes it does require the bones to be “set” or put back in alignment.  Open surgery is usually reserved for fractures with significant displacement, or recurrent displacement after attempted reduction and immobilization.

Don’t Ignore Wrist Injuries

Wrist fractures, like essentially all broken bones are best treated when treated early.  This may be as simple and putting a brace on, which will immobilize and protect the bone easing the pain and preventing displacement.

Some fractures, like the scaphoid fracture, have poor outcomes when treated late.  Due to its unique blood supply, scaphoid fractures have higher risk of non-healing or nonunion than other wrist bones.  When this bone does not heal, it will, overtime, develop a predictable pattern of wrist arthritis.

How to Prevent a Broken or Sprained Wrist

My best advice--try not to fall! This may seem common sense, but many times the cause is preventable. Loose rugs, items on the floor, unsafe ladder use, all are preventable common causes of falls.  As much as we love our pets, we must also be careful with them around our feet as well.

Second to that, there are a few things you can do to prevent a wrist injury should you fall.

  • Be proactive and build bone strength with a diet containing sufficient calcium and vitamin D and doing weight-bearing exercises
  • Wear protective gear for sports activities, especially skateboarding and rollerblading
  • Take care when walking on slippery or bumpy surfaces
