A dislocation is a separation of two bones where they meet at a joint. Joints are areas where two bones come together.
A dislocated bone is no longer in its normal position.
It may be hard to tell a dislocated bone from a broken bone. Both are an emergency. You will need the same first aid treatment.
Most dislocations can be treated in a doctor's office or emergency room. You may be given medicine to make you sleepy and to numb the area. Sometimes, general anesthesia in the operating room is needed.
When treated early, most dislocations will not result in permanent injury.
- Injuries to the surrounding tissues generally take 3 - 6 weeks to heal. Sometimes, surgery to repair a torn ligament is needed.
- Injuries to nerves and blood vessels may result in more long-term or permanent problems.
Once a joint has been dislocated, it is more likely to happen again. Follow-up with an orthopedic surgeon is recommended after a dislocation.
Dislocations are usually caused by a sudden impact to the joint. This usually occurs following a blow, fall, or other trauma.
A dislocated joint may be:
- Accompanied by numbness or tingling at the joint or beyond it
- Intensely painful, especially if you try to use the joint or bear weight on it
- Limited in movement
- Swollen or bruised
- Visibly out of place, discolored, or misshapen
Nursemaid's elbow is a partial dislocation common in toddlers. The main symptom is refusal to use the arm. Nursemaid's elbow can be easily treated in a doctor's office.
- Do NOT move the person unless the injury has been completely immobilized.
- Do NOT move a person with an injured hip, pelvis, or upper leg unless it is absolutely necessary. If you are the only rescuer and the person must be moved, drag him or her by the clothing.
- Do NOT attempt to straighten a misshapen bone or joint or to change its position.
- Do NOT test a misshapen bone or joint for loss of function.
- Do NOT give the person anything by mouth.
Call immediately for emergency medical assistance if
Call 911 if the person has:
- A bone projecting through the skin
- A known or suspected dislocation or broken bone
- An area below the injured joint that is pale, cold, clammy, or blue
- Severe bleeding
- Signs of infection, such as warmth or redness at the injured site, pus, or a fever
Preventing injuries in children:
- Create a safe environment around your home.
- Pay careful attention to preventing falls by gating stairways and keeping windows closed and locked.
- Supervise children carefully. There is no substitute for close supervision no matter how safe the environment or situation appears to be.
- Teach children how to be safe and look out for themselves.
Preventing dislocations in adults:
- Avoid falls by not standing on chairs, countertops, or other unstable objects.
- Eliminate throw rugs, especially for the elderly.
- Wear protective gear when participating in contact sports.
For all age groups:
- Keep a first aid kit handy.
- Remove electrical cords from floor surfaces.
- Use handrails on staircases.
- Use nonskid mats on the bottom of the bathtubs and avoid bath oils.
