Bones of the forearm include the radius and the ulna.
Cause
Sometimes, the other bone of the forearm (the ulna) is also broken. When this happens, it is called a distal ulna fracture. This type of fracture was first described by an Irish surgeon and anatomist, Abraham Colles, in 1814; hence the name, "Colles " fracture. However not all distal radius fractures are "Colles" fractures. Many different fracture patterns can occur when the distal radius is fractured and often medical eponyms such as "colles" fracture do not fully describe the extent of the injury.
Symptoms
A broken or fractured wrist usually causes immediate (acute) pain, tenderness, bruising, and swelling. Frequently, the wrist hangs in an odd or bent way (deformity).
Diagnosis
The fracture typically occurs about 1 inch from the end of the bone. However the pattern of the The (fracture) can occur in many different ways. A fracture may extends into the joint, and if so it is called an intra-articular fracture. A fracture that does not extend into the joint is called an extra-articular fracture. ("Articular" means "joint.") When a fractured bone breaks the skin, it is called an open fracture. When a bone is broken into more than two pieces, it is called a comminuted fracture. It is important to classify the type of fracture, because some fractures are more difficult to treat than others. Intra-articular fractures (fractures within the joints), open fractures (fractures that break through the skin), and comminuted fractures (fracture that shatter the bone into a lot of small pieces) are more difficult to treat, for example.
Risk Factors
Osteoporosis (decreased density of the bones) can make a relatively minor fall result in a broken wrist. Many distal radius fractures in people older than 60 years of age are caused by a fall from a standing position. A broken wrist can happen even in healthy bones, if the force of the trauma is severe enough. For example, a car accident or a fall off a bike may generate enough force to break a wrist. Good bone health remains an important prevention option. Wrist guards may help to prevent some fractures, but they will not prevent them all.
Treatment
Immediate TreatmentIf the injury is not very painful and the wrist is not deformed, it may be possible to wait until more definitive care is available. The wrist may be protected with a splint. An ice pack often can be applied to the wrist and the wrist can be elevated until the treating doctor is able to examine it. If the injury is very painful, if the wrist is deformed, if there is any numbness, if the fingers are not pink, or there are open wounds it is necessary to go to the emergency room. Nonsurgical TreatmentThere are many treatment choices. The choice depends on many factors, such as the nature of the fracture, age and activity level, and surgeon's personal preferences. The following is a general discussion of the possible options. Casting: If the broken bone is in a good position, a plaster or fiberglass cast may be applied until the bone heals sufficiently. 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 would be re-aligned (reduced). If the bone is straightened (reduced) without having to open the skin (incision), this is called a closed reduction.
X-rays may be taken, depending on the nature of the fracture. X-rays may be taken at set intervals depending upon the nature of the fracture, the patients age and the physicians preferences. if the fracture was reduced or thought to be unstable X rays may be taken more often. X-rays may be taken less often if the fracture was not reduced and thought to be stable. As mentioned previously often X-rays of the non injured side are used to compare the injury. A physician may want to look at whether the fracture has caused the radius to shorten or angulate beyond acceptable limits. Sometimes these comparision Xrays may prompt the physician to discuss surgery even weeks after the intital treatment begins. The cast is typically removed about six weeks after the fracture happened. However this time may differ. At that point, occupational and hand therapy is often started to help improve the motion and function of the injured wrist. Not all fractures need therapy. Surgical Treatment
There are many ways of performing surgery. Even if the fracture is treated in the operating room, it may be possible to re-align (reduce) the fracture without making an incision (closed reduction). In other cases, it will be necessary to make an incision (open reduction) to directly access the broken bones to improve alignment. 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 Surgery
What can I expect while my bone is 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. One combination is ibuprofen plus acetaminophen ("non-aspirin pain reliever"). The combination of both ibuprofen plus acetaminophen is much more effective than either one alone. If pain is severe, patients may need to take a prescription strength medication, often a narcotic, for a few days. If you are taking a narcotic with acetaminophen or tylenol added you should be careful not to inadvertantly exceed the recommended tylenol dose Casts and splints must be kept dry. A plastic bag over the arm while showering should help. If the cast does become wet, it will not dry very easily. A hair dryer on the cool setting may be helpful. Most surgical incisions must be kept clean and dry until the sutures (stitches) are removed. What can I expect after my bone has healed?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.
Remember, these are general guidelines and may not apply to you and your fracture. Ask your doctor for specifics in your case. Your doctor knows that returning to activities is important to you. 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.
