What is a closed fracture?
A.
A fracture where the bone breaks through the skin
B.
A fracture where the bone is out of alignment
C.
A fracture where the bone is completely broken in two
D.
A fracture where the skin remains intact over the fractured bone
The Correct answer and Explanation is:
The correct answer is D. A fracture where the skin remains intact over the fractured bone.
A closed fracture, also known as a simple fracture, is a type of bone fracture where the broken bone does not pierce through the skin. This distinguishes it from an open fracture (or compound fracture), in which the bone protrudes through the skin, exposing the bone and surrounding tissues to the external environment. Closed fractures are generally considered less complicated than open fractures because they have a lower risk of infection, which can occur in cases where the skin barrier is broken.
Closed fractures can occur in various forms, including transverse fractures (where the break is straight across the bone), oblique fractures (where the break is at an angle), and comminuted fractures (where the bone is shattered into multiple pieces). They can result from different types of trauma, such as falls, sports injuries, or car accidents. The degree of pain, swelling, and bruising may vary depending on the location and severity of the fracture.
Diagnosis typically involves a physical examination and imaging studies, such as X-rays, to visualize the extent and nature of the fracture. Treatment for a closed fracture often includes immobilization through the use of casts or splints, and in some cases, surgical intervention may be necessary to realign the bones or stabilize them with hardware such as pins or plates.
The healing process for closed fractures usually takes several weeks to months, during which the patient may need physical therapy to regain strength and mobility in the affected area. Overall, closed fractures can be effectively managed, allowing individuals to return to their normal activities with appropriate care and rehabilitation.
