An acetabular fracture is a serious injury involving the socket portion of the hip joint. Because the acetabulum forms the cup that holds the femoral head in place, damage to this area can significantly affect mobility, stability, and long-term joint health. These injuries often result from high-energy trauma, such as car accidents or significant falls, and require prompt medical evaluation to prevent lasting complications.

If you are experiencing hip pain after an injury, contact our practice in Zanesville, OH, today to schedule a consultation and receive expert, compassionate care tailored to your recovery.
The acetabulum forms the hip socket, where the upper femur meets the pelvis to create the hip joint. A fracture is a break in the bone, and fractures of the acetabulum can disrupt the smooth surface of the articular cartilage, which allows the joint to move freely.
Medical care is often required because most acetabular fractures occur during high-impact events. Acetabular fractures vary widely in severity, from small cracks in the bony rim to complex injuries with displaced bone fragments or open fractures where broken bone fragments stick outside the skin.
Common acetabular fractures include the following:
Because tissue called ligaments connect the pelvis and femur or tibia bone structures for stability, high-energy trauma can cause associated damage beyond the hip socket cartilage itself.
Most acetabular fractures are caused by high-energy trauma, such as:
In younger individuals, strong bone typically requires substantial force to break. In elderly patients, however, weak or insufficient bone due to osteoporosis can lead to acetabulum fractures even after a lower-impact fall.
The direction of force determines the fracture patterns. For example, a direct blow to the knee can drive the femoral head into the hip socket, resulting in posterior wall or posterior column injuries. Less commonly, sports injuries or direct blows may cause an anterior wall injury.
Symptoms are usually immediate and severe. Because the acetabulum is central to the hip joint, patients often experience:
If the sciatic nerve runs near the injury site and becomes compressed or stretched, a sciatic nerve injury may occur. This can cause numbness, tingling, or weakness in the leg or foot. Damage involving the sciatic nerve requires urgent assessment to prevent long-term nerve dysfunction.
An acetabular fracture diagnosed in the emergency setting begins with a thorough physical examination and imaging studies. Standard X-rays help identify fractures of the acetabulum, but computed tomography (CT) scans provide more detailed images of the bone and any displaced bone fragments.
Early diagnosis and treatment can minimize long-term joint damage.
Treatment depends on fracture severity, fragment displacement, patient age, and overall health.
Non-surgical management may be appropriate when:
Conservative care may include:
Regular follow-up imaging ensures that bone fragments do not shift during healing.
Surgery is recommended when fracture fragments are significantly displaced, when the joint surface is disrupted, or when the hip is unstable. The goal is anatomical reduction and internal fixation to restore alignment and preserve joint function. Before the surgical procedure, a temporary procedure called skeletal traction may be used to hold the hip in place. This involves using a metal pin to hold the bones together.
A common surgical procedure for acetabular fractures is open reduction and screw and plate fixation. During surgery, the orthopaedic surgeon repositions displaced bone fragments and secures them to allow proper healing.
In severe cases, particularly in elderly patients with extensive joint damage, total hip replacement may be considered.
Recovery depends on the complexity of the injury and treatment approach. Most patients require:
Because the hip joint supports body weight, premature stress can interfere with healing. Full recovery may take 6–18 months.
Despite proper treatment, complications can occur. These may include:
Outcomes vary depending on fracture type, patient health, and the timeliness of treatment. With accurate alignment and stable internal fixation, many patients regain good hip function and mobility.
However, because acetabular fractures vary in complexity, some individuals may experience lingering stiffness or arthritis. Early intervention, expert surgical technique, and adherence to rehabilitation significantly improve long-term results.
If you experience severe hip pain after a fall or accident, do not ignore the symptoms. Early evaluation and specialized orthopaedic care can prevent complications and preserve long-term mobility. The team at Orthopaedic Associates of Zanesville in Zanesville, OH, is experienced in diagnosing and treating complex hip injuries, including fractures of the acetabulum.

An acetabular fracture is a break in the socket portion of the pelvis that forms part of the hip joint. This socket holds the femoral head in place, allowing smooth movement of the leg. When the socket is fractured, the stability and alignment of the hip joint can be disrupted, potentially leading to long-term pain, stiffness, and joint damage if not treated properly.
An acetabular fracture that impacts the femoral head can be especially serious. If the femoral head is damaged or loses its blood supply, complications such as joint collapse or arthritis may develop. Because the femoral head is essential for smooth hip joint movement, injuries involving both structures often require careful monitoring or surgical treatment.
Posterior wall fractures typically occur due to high-impact trauma, such as car accidents, where force travels through the knee into the hip joint. This drives the femoral head backward into the socket, breaking the posterior wall. These injuries are among the most common patterns seen in high-energy hip trauma cases.
Yes, an acetabular fracture can sometimes cause sciatic nerve injury. The sciatic nerve runs close to the back of the hip joint, and when fractures occur—especially posterior wall fractures—the nerve can be stretched, compressed, or bruised. This may lead to numbness, tingling, weakness, or difficulty moving the foot.
An anterior wall fracture affects the front portion of the hip socket, while posterior wall fractures involve the back portion. Posterior injuries are generally more common and often result from dashboard-type car accidents. Anterior injuries may occur from different force directions and can affect hip stability in different ways.
