Traumatic osteomyelitis

Introduction to traumatic osteomyelitis Traumatic osteomyelitis mainly refers to osteomyelitis caused by firearm injury, open fracture or open reduction and internal fixation for direct contamination of the fracture end or exposed area. It is characterized in that the infection is mainly confined to the fracture site, and the nearby soft tissue also presents an acute suppurative inflammatory state. Once the bone is contaminated and the infection is formed, most of the infection is chronic, and the infected bone end is free of periosteum and blood supply. Necrosis, due to skin defects and swelling of the limbs, soft tissue may be difficult to cover and cause the bone to be exposed, resulting in aggravation of necrosis. The soft tissue is coated with a good part of the bone, and the part can be gradually replaced by crawling, and the dead bone and the living bone are broken. The role of bone cells and proteolytic enzymes gradually separates the dead bones, eventually leaving the main bone and remaining in the deep, or excreted. basic knowledge The proportion of illness: 0.0016% Susceptible people: no specific people Mode of infection: non-infectious Complications: bone defect, nonunion

Causes of traumatic osteomyelitis

Causes

One of the most common causes of traumatic osteomyelitis is postoperative infection of open fractures, followed by infections after open reduction or other bone and joint surgery, which can be acute or chronic, with lesions near the fracture end, acute phase The infection is most serious in the intramedullary cavity. The patient has hyperthermia, chills and other symptoms of toxemia, similar to acute hematogenous osteomyelitis. Another reason is the skin near the fracture, the muscle necrosis infection, and the fracture segment that loses blood supply. Exposure to air and dry necrosis, the course of the disease into chronic, often accompanied by infectious nonunion or bone defects.

Traumatic osteomyelitis prevention

This disease is often caused by traumatic infection, such as kicking, falling or car accident damage. Therefore, pay attention to living habits, high-risk workers, such as construction workers, mining workers are prone to damage, should pay attention to protect themselves in the course of work. Pay attention to calmness and avoid emotional conflicts leading to the disease. Secondly, early detection, early diagnosis and early treatment are also important for indirect prevention of this disease.

Traumatic osteomyelitis complications Complications, bone defect, nonunion

In the advanced stage, there may be skin defects, nonunion or bone defects.

Traumatic myeloinflammatory symptoms Common symptoms Severe pain High hyperthermia Increased bone density

1. Acute phase: manifested as systemic symptoms often caused by acute inflammatory phase such as high fever after bone fracture or bone surgery, and local symptoms such as redness, swelling, pain, depressed edema and tenderness, wound or bone surface There is a pus overflow or a significant increase in secretions.

2. Chronic phase: The main manifestation is that the wound can not be closed, the sinus can be left behind or the bone is exposed, and the wound secretion is more. Because of the infection on the surface of the bone, it forms a dead space surrounded by bones.

Examination of traumatic osteomyelitis

In the acute phase, the white blood cells and neutrophils in the blood of patients are significantly increased, and the erythrocyte sedimentation rate is increased.

On the X-ray film, the bone density at the bone end of the dead bone area was higher than normal, and the density around the dead bone was reduced.

Diagnosis and diagnosis of traumatic osteomyelitis

According to the medical history, systemic symptoms, local symptoms and X-ray findings, a diagnosis can be established.
