S32.422 Displaced fracture of posterior wall of left acetabulum

Name of the Condition

• Displaced fracture of posterior wall of left acetabulum

Summary

This condition involves a displaced fracture of the posterior wall of the left acetabulum, the socket portion of the hip joint where the femur (thigh bone) articulates with the pelvis. The acetabulum is part of the pelvic bone and is critical for hip stability and movement. Displacement of the posterior wall can disrupt joint function and may require specific management depending on the fracture's severity and alignment.

Causes

Typically caused by high-impact trauma, such as motor vehicle accidents, falls from height, or direct blows to the hip. Less commonly, fractures may result from low-impact events in individuals with weakened bones (e.g., osteoporosis).

Risk Factors

• Advanced age, as bone density naturally decreases.
• Osteoporosis or other bone-weakening conditions.
• Participation in high-impact sports or activities.
• Previous hip or pelvic injuries.
• Certain medical conditions that affect bone strength.

Symptoms

• Severe hip or groin pain, often worsening with movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or tenderness around the hip.
• Limited range of motion in the hip joint.
• Possible deformity or abnormal positioning of the hip.

Diagnosis

Physical examination to assess pain, swelling, and hip function. Imaging tests, such as X-rays or CT scans, are typically used to confirm the fracture, evaluate displacement, and assess joint integrity. Additional imaging may be required to rule out associated injuries.

Treatment Options

Treatment depends on fracture severity and displacement. Non-surgical options include pain management, activity modification, and physical therapy for stable fractures. Surgical intervention, such as open reduction and internal fixation, may be necessary for displaced fractures to restore joint alignment and stability.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient factors. Most patients recover function with appropriate management, but recovery may take several months. Follow-up imaging and physical therapy are often recommended to monitor healing and restore mobility.

Complications

Potential complications include post-traumatic arthritis, chronic pain, hip instability, nerve or vascular injury, and deep vein thrombosis. Infection or nonunion of the fracture may occur in some cases.

Lifestyle & Prevention

Avoid high-impact activities that risk hip injury. Maintain bone health through adequate calcium and vitamin D intake, and engage in weight-bearing exercise to support bone density. Use protective gear during sports and follow safety measures to prevent falls.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or deformity after trauma. Persistent pain, swelling, or difficulty walking after injury also warrants evaluation.

Tips for Medical Coders

Code S32.422 is specific to a displaced fracture of the posterior wall of the left acetabulum. Ensure documentation specifies the side (left), displacement, and anatomical location. Differentiate from non-displaced or bilateral fractures, as these require distinct coding. Verify that the fracture is not associated with open wounds or other complicating factors, as these may affect code assignment.
