What is Trauma?

What is Trauma?Trauma is a serious injury or shock to the body. It is caused by a physical force such as violence or an accident. The injury may be complicated by psychiatric, behavioral, and social factors.

It is critical to have an entire team immediately available to provide care to an injured patient 24-hours a day. This teamwork starts at the scene of the injury where a coordinated, statewide pre-hospital medical system rapidly transports the injured patient from the scene to the hospital providing the appropriate level of care according to criteria established in the statewide trauma regulations. Once at the hospital, a complete team of surgeons, emergency physicians and nurses continue the life-saving treatment.

This team approach to care of the injured patient has had a dramatic impact on saving lives.

Minimally Invasive Procedures for Massive Bleeding

Injuries take many forms. The most advanced hospitals can treat injuries with a variety of approaches that involve well-known ones, like surgery, and newer ones where minimally invasive procedures can replace some surgeries.

As a Level 1 Trauma Center, Hartford Hospital has Interventional Radiologists as part of the Trauma Team. They perform procedures such as "embolization" which is a recognized interventional radiology technique that is used to treat trauma patients with massive bleeding.

Dual Energy X-ray Absorptiometry

Definition

Dual energy X-ray absorptiometry (DEXA) is a test that measures the density (or thickness) of your bones.

The DEXA scan is an x-ray scan that uses a small amount of radiation to take pictures of different bones. These pictures are used to measure the density of the bones at the spine, hip, forearm. It can also take pictures of other bones such as a finger or the heel bone. Measurements of the spine and hip are called central DXA. Those done on the arms or legs are called peripheral DXA. In some cases, your doctor may order a whole body scan.

Reasons for Test

This test will help your doctor assess the density of your bones. It will help determine if you have osteoporosis, a bone-thinning disease. This information may be used to predict your risk of bone fractures.

Possible Complications

An x-ray uses radiation to make images. The low levels of radiation from a single x-ray will not effect most people. If you are pregnant or think you may be pregnant talk to your doctor before the x-ray. Radiation may be harmful to developing babies.

What to Expect

  • Eat normally on the day of the test.
  • Wait up to two weeks before having a DEXA scan if you have had a barium study or if you have been injected with contrast dye for a CT scan or MRI.
  • Wear loose, comfortable clothing. Do not wear clothing with metal zippers, belts, or buttons.
  • If there is any possibility that you are pregnant, let the staff know.

Central DXA measures bone density in the hip and spine. You will be asked to lie on a table. Your position will depend on the area being examined. You will be asked to hold still and may be asked to hold your breath while the X-ray is taken. The X-ray will be taken and sent to a computer monitor.

Peripheral DXA measures bone density in the finger, hand, forearm, or foot. The area being examined will be placed in a small device. The device will provide a bone density reading in a few minutes.

You will be able to leave after the test is done.

About 10 minutes

No

The test results are usually available within a few days. Your test results will show two types of scores:

  • T score—This number shows the amount of bone you have in comparison to a young adult of the same gender with peak bone mass. A score above -1 is considered normal. A score between -1 and -2.5 may mean you have osteopenia, the first stage of bone loss. A score below -2.5 means you may have osteoporosis.
  • Z score—This number shows the amount of bone you have in comparison to other people of your age group, gender, and race.

These test results will help your doctor determine your risk for bone fractures.

Call Your Doctor

Call your doctor if you have any questions about your condition, the test, or your test results.
