The radius is the larger of the two bones of the forearm. The end toward the wrist is called the distal end. A distal radius fracture occurs when the area of the radius near the wrist breaks. There are many treatment choices. The choice depends on many factors, such as the nature of the fracture, age, and activity level.
If the broken bone is in a good position, a cast may be applied until the bone heals.
If the position (alignment) of your bone is not good and likely to limit the future use of the arm, it may be necessary to correct the deformity. The bone may be re-aligned (reduced) to a correct position (this is called a closed reduction) and would not require surgery. Casting the arm would still take place.
Sometimes, the position of the bone is so much out of place that it cannot be corrected or kept corrected in a cast. This has the potential of interfering with the future functioning of your arm. In this case, surgery may be required.
Depending on the fracture, there are a number of options for holding the bone in the correct position, including a cast, metal pins (usually stainless steel or titanium), a plate and screws, an external fixator (a device for which most of the hardware remains outside of the body), or any combination of these techniques.
After the bone is properly aligned, a splint or cast may be placed on your arm. The splint is usually used for the first two weeks. A custom removable splint is then typically used for another month after that to allow early range of motion exercises and physical therapy.
X-rays may be taken, depending on the nature of the fracture. These are used to verify reduction of the fracture, ensure maintenance of alignment and to follow healing.
The kinds of distal radius fractures are so varied and the treatment options are so broad that it is hard to generalize what to expect.
Most fractures hurt moderately for a few days to a couple of weeks. Many patients find that using ice, elevation (holding their arm up above their heart), and simple, non-prescription medications for pain relief are all that are needed.
Most casts are waterproof. However, if you have an initial splint or a cast that is not water-proof, or had surgery, you must keep it dry. If it does get wet, blow-drying on the coolest set-ting will help to keep it dry. Most surgical incisions must be kept clean and dry until the stitches or staples are removed.
Most patients do return to all their former activities. The nature of the injury, the kind of treatment received, and the body’s response to the treatment all have an impact, so the answer is different for each individual.
Some generalizations can be made.
Finally, osteoporosis is a factor in as many as 250,000 wrist fractures. It has been suggested that people who suffer a wrist fracture may need to be screened for osteoporosis, especially if they have other risk factors. Ask your doctor if you need to be screened or treated for osteoporosis. This will need to be managed by your primary physician.
