Acetabular Fracture

Acetabular fractures require specific care and treatment. In the following text, we’ll discuss the complex fracture and its treatment.

If you’re looking for a hip specialist, you are in the right place!


What Is An Acetabular Fracture?

The acetabular surrounds the pelvis; it has an inverted “Y” shape. In layman terms, an acetabular fracture is the breaking of the socket part of the “ball and socket” hip joint.

The acetabular cartilage supports body weight and movement. Unlike other types of tissues in the body, it does not regenerate.

The body’s weight is balanced on the anterior and posterior columns of the acetabulum. The anterior column is larger and consists of the anterior wall and the iliac crest to the pubic symphysis. The posterior columns come from the ischial notch and go to the ischial tuberosity.

Acetabular Fracture

This type of fracture is caused by impact on the femoral head on the acetabulum. Such force can be applied both from the greater trochanter (through the axis of the femoral neck) and through a trauma pressure from the axis of the limb.

Fracture Patterns

The fracture patterns found in the acetabulum depend on the direction of the applied force and the position of the hip during impact. Depending on this position, there will be a greater impact on the anterior, posterior, or bottom of the acetabulum.

Each of these variables will produce different fracture patterns.

Acetabular Fractures From Other injuries

In 50% of the cases, acetabular fractures result from other kinds of injuries, including injuries to the skull, chest, and abdomen.

Acetabular Fractures In Young People

Young people are more prone to experiencing acetabular fractures because they are frequently observed during automobile accidents and other high-energy activities.

Elderly folks may experience these fractures during fall accidents.

Radiological Evaluation

X-rays are used to determine the fracture pattern. In the radiological evaluation, six main lines are looked at, including the posterior border, anterior border, ceiling; tear, ilio-ischiatic line and iliopectineal line.

Computed Tomographs

These may aid the diagnosis, but they can’t replace X-rays.

Consequences, Prognosis And Treatments

The cartilage may experience some degeneration due to the trauma and present post-traumatic coxarthrosis; this may last years after the fracture.

In case of hip dislocation where the joints are disengaged, there may also be necrosis of the femoral head and traumatic injuries to the sciatic nerve.


The prognosis depends on the severity of the injury and the patient’s conditions. Generally, if the injury occurs outside the cargo area, the prognosis is better, but the medical team will only be able to confirm this a few months after the treatment begins.

Conservative Treatment

Conservative treatment may be possible in cases of a stable fracture that don’t present any deviation. It may be used in some cases of deviated fractures where the integral part of the acetabulum allows stability and congruence.


Surgical treatment depends on iliofemoral and ilioinguinal. It occurs in all cases where there is instability and incongruity of the acetabulum.


The fractures can be fixed using traction plates and screws. Post-traumatic arthrosis is one of the most common complications that occur. Hip arthroplasty may be performed in elderly people with severe fractures during the “repair” stage.


Acetabular fractures are complex fractures that can cause major discomfort. These fractures need to be treated as soon as possible because the fractured area helps carry the body’s weight.

Make A Diagnosis

Good diagnoses followed by correct treatment can help speed up recovery, and prevent unnecessary complications by competent professionals. It is effective for consolidating the fracture and to prevent further problems caused by the lack of proper diagnosis and treatment.
