A nondisplaced fracture occurs when a bone cracks or breaks, but the pieces maintain their natural position and alignment. While often considered less severe than other bone breaks, a common concern is whether this type of fracture can shift or worsen after the initial injury.
The Potential for Displacement
A nondisplaced fracture can indeed become displaced. In a displaced fracture, the broken ends of the bone no longer line up correctly, often creating a gap or an angle between them.
Displacement can lead to several implications for healing and recovery. There is an increase in pain, which may be sudden and severe. It can also necessitate more involved medical interventions, as displaced fractures frequently require surgical procedures to realign the bone fragments.
These surgeries often involve the use of internal fixation devices like metal plates, screws, or rods to stabilize the bone during healing. The healing process for a displaced fracture may also be longer, and there is an increased potential for complications. Such complications can include damage to surrounding muscles, nerves, or blood vessels, and a higher risk of infection if the skin is broken.
Factors Leading to Displacement
Several factors can contribute to a previously nondisplaced fracture becoming displaced. One common cause is new trauma or impact to the injured area. Even a seemingly minor fall or bump can generate enough force to shift the bone fragments out of alignment.
Another significant factor is failing to follow medical advice regarding activity and weight-bearing restrictions. Placing stress on the healing bone, such as bearing weight too soon on a lower limb fracture, can cause the bone fragments to move. Inadequate immobilization can also lead to displacement. If a cast, splint, or brace is not properly fitted, maintained, or is removed prematurely, it may not provide sufficient support to keep the bone fragments stable.
Recognizing and Preventing Displacement
Recognizing the signs of a displaced fracture is important for prompt medical attention. A sudden, notable increase in pain at the fracture site often indicates a shift in the bone. Other signs can include new or worsening swelling, a visible deformity, or changes in sensation such as numbness or tingling in the affected limb. If any of these symptoms appear, it is important to seek medical evaluation immediately.
Preventing displacement involves adhering to medical guidance throughout the healing process. Following all of the doctor’s instructions, including any limitations on activity or weight-bearing, is important. Proper use and care of immobilization devices, such as keeping a cast dry and intact, helps maintain the stability needed for healing. Avoiding activities that place undue stress on the mending bone and attending all scheduled follow-up appointments for imaging and assessment are also important steps to ensure the fracture heals correctly.
