Unlabelled:
An open fracture is one in which the bone segments penetrate into the skin leaving the bone in contact with the outer environment. Many microorganisms may cause wound infection in open fractures; the most common one is Staphyloccocus aureus.
Methods:
This study included a group of 75 patients of both genders seen from November 1st, 2009 to April 30, 2010. A sample for culture was taken upon admission and incubated for 48 hours.
Results:
A total of 75 patients were included, 62 males and 13 females. The age range was 18 to 83 years. The tibia and the fibula were the most commonly affected bones. The most common mechanisms of injury resulted from high energy. The most frequent grade of exposure was III B. Forty-six percent of the culture results were negative at 48 hours; the most frequent organisms found in the positive cultures were Staphylococcus aureus and Candida albicans.
Conclusions:
Males are the gender most affected by open fractures. This kind of condition occurs at productive ages. The time elapsed between the injury and the onset of treatment was significant. The culture results showed that the most frequent organism was Staphylococcus aureus, together with Candida albicans.
Insights
Open fractures, often caused by high-energy trauma, most commonly affect males and occur at productive ages. Staphylococcus aureus and Candida albicans were the most frequent organisms found in wound infections.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Microbiology
Context:
- Open fractures involve bone segments penetrating the skin, exposing the bone to the external environment.
- Wound infections are a significant complication of open fractures, with Staphylococcus aureus being a common pathogen.
Purpose:
- To identify the prevalence of microorganisms in open fracture wound infections.
- To analyze patient demographics and injury characteristics associated with open fractures.
Summary:
- A study of 75 patients (62 males, 13 females) with open fractures revealed that high-energy mechanisms were common, with the tibia and fibula frequently affected (Grade III B exposure).
- Of the cultures taken, 46% were negative. Positive cultures most frequently identified Staphylococcus aureus and Candida albicans as causative agents.
Impact:
- Highlights the predominant pathogens in open fracture infections, guiding empirical treatment strategies.
- Emphasizes the vulnerability of males during their productive years to high-energy trauma leading to open fractures.
- Underscores the importance of timely treatment initiation to mitigate complications.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
