S32.413 Displaced fracture of anterior wall of unspecified acetabulum

Name of the Condition

• Displaced fracture of anterior wall of unspecified acetabulum

Summary

This condition involves a break in the anterior wall of the acetabulum, the socket portion of the hip joint where the femur (thigh bone) articulates with the pelvis. The fracture is displaced, meaning the bone fragments are not aligned properly. This injury disrupts hip joint stability and may require specific management based on the extent of displacement and associated damage to surrounding structures.

Causes

Typically caused by high-impact trauma, such as motor vehicle accidents, falls from height, or direct force to the hip. Less commonly, it 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 used to confirm the fracture and evaluate displacement. Additional imaging may be needed to assess associated joint or soft tissue damage.

Treatment Options

Management depends on fracture severity and displacement. Non-surgical options include pain management, activity modification, and physical therapy. Surgical intervention may be required for unstable or severely displaced fractures, involving techniques like open reduction and internal fixation to restore alignment and joint stability.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient factors. Recovery may take several months, with physical therapy often necessary to restore mobility and strength. Regular follow-up imaging and clinical assessments help monitor healing and detect complications.

Complications

Potential complications include post-traumatic arthritis, persistent pain, hip instability, nerve or vascular injury, and deep vein thrombosis. Infection or nonunion of the fracture may occur, particularly with surgical intervention.

Lifestyle & Prevention

Avoid high-impact activities that increase fracture risk. Maintain bone health through adequate calcium and vitamin D intake, and engage in weight-bearing exercises to support bone density. Use protective gear during sports and fall prevention strategies, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible deformity after trauma. Persistent pain, swelling, or difficulty walking after initial treatment also warrants evaluation.

Tips for Medical Coders

Code S32.413 is used for a displaced fracture of the anterior wall of the acetabulum when the side is unspecified. Ensure documentation specifies "displaced" and "anterior wall" to support accurate coding. If laterality (right/left) is documented, use the corresponding laterality-specific code instead.
