A forearm fracture is caused by trauma to the bone. Trauma may include: Fall on an outstretched armFall directly on the forearmDirect blow to the forearmTwisting the arm beyond the elbow's normal range of motion
Forearm fracture is more common in older adults.
Factors that may increase your risk of forearm fracture include: Osteoporosis
Certain diseases or conditions that result in bone or mineral loss, such as abnormal or
menstrual cycles, or post-
menopauseCertain diseases and conditions that weaken bones, such as tumors or cystsPoor nutritionCertain congenital bone conditionsDecreased muscle massParticipating in contact sportsViolence
A forearm fracture may cause: Pain, often severeTenderness, swelling, and bruising around the injuryDecreased range of motionA lump or visible deformity over the fracture site
You will be asked about your symptoms, your physical activity, and how the injury occurred. The injured area will be examined.
Imaging tests assess the bones, surrounding structures, and soft tissues. This can be done with: X-rayCT scanMRI scan
Proper treatment can prevent long-term complications or problems with your forearm. Treatment will depend on how serious the fracture is, but may include:
Extra support may be needed to protect, support, and keep your forearm in line while it heals. Supportive steps may include a splint, brace, or cast. A sling may be necessary to help stabilize your arm.
Some fractures cause pieces of bone to separate. Your doctor will need to put these pieces back into their proper place. This may be done: Without surgery—you will have anesthesia to decrease pain while the doctor moves the pieces back into placeWith surgery—pins, screws, plates, or wires may be needed to reconnect the pieces and hold them in place
Children’s bones are still growing at an area of the bone called the growth plate. If the fracture affected the growth plate, your child may need to see a specialist. Injuries to the growth plate will need to be monitored to make sure the bone can continue to grow as expected.
The following medications may be advised: Over-the-counter medication to reduce inflammation and painPrescription pain medication
Check with your doctor before taking nonsteroidal anti-inflammatory drugs, such as ibuprofen or aspirin.
Note: Aspirin is not recommended for children or teens with a current or recent viral infection. This is because of the risk of Reye syndrome. Ask your doctor which medications are safe for your child.
You may be referred to physical therapy or rehabilitation to start range-of-motion and strengthening exercises.
