Malgaigne's fracture

Malgaigne's fracture is a type of pelvic fracture that involves a double vertical fracture of the pelvis. It is named after the French surgeon Joseph-François Malgaigne, who first described this injury in the 19th century.

Anatomy

The pelvis is a ring-like structure located at the base of the spine, which is made up of several bones: the sacrum, the coccyx, and the left and right hip bones. Each hip bone is further divided into three parts: the ilium, the ischium, and the pubis. Malgaigne's fracture typically involves fractures of the pubic rami and the ilium.

Mechanism of Injury

Malgaigne's fractures are usually caused by high-energy trauma, such as motor vehicle accidents or falls from a significant height. The force of the impact causes a vertical shear force that splits the pelvis into two halves.

Diagnosis

Diagnosis of a Malgaigne's fracture is typically made through a combination of physical examination and imaging studies. X-rays and CT scans are commonly used to visualize the fracture and assess its severity.

Treatment

Treatment of Malgaigne's fractures depends on the severity of the injury and the patient's overall health status. Non-operative treatment may include pain management and physical therapy. In more severe cases, surgical intervention may be necessary to stabilize the pelvis and prevent further injury.

Prognosis

The prognosis for a Malgaigne's fracture depends on the severity of the fracture and the patient's overall health status. With appropriate treatment, many patients can make a full recovery. However, complications such as infection, blood clots, and nerve damage can occur.
