S32.472 Displaced fracture of medial wall of left acetabulum

Name of the Condition

• Displaced fracture of medial wall of left acetabulum

Summary

This condition involves a break in the medial 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 plays a critical role in hip stability and movement. A displaced fracture means the bone fragments are no longer aligned properly, which can disrupt joint function and may require specific management depending on the fracture's severity.

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 and evaluate displacement. Additional imaging may be required to assess associated injuries or joint stability.

Treatment Options

Treatment depends on fracture severity and displacement. Nonsurgical options include pain management, activity modification, and physical therapy. Surgical intervention may be necessary for displaced fractures to realign and stabilize the bone, often using internal fixation devices. Post-treatment rehabilitation focuses on restoring hip function and strength.

Prognosis and Follow-Up

Prognosis varies based on fracture severity, treatment, and patient factors. Most patients recover with appropriate management, though some may experience long-term hip stiffness or arthritis. Follow-up care includes regular imaging to monitor healing and physical therapy to optimize recovery. Long-term outcomes depend on adherence to rehabilitation and management of any complications.

Complications

Potential complications include nonunion or malunion of the fracture, post-traumatic arthritis, nerve or blood vessel injury, and chronic hip pain. Infection or hardware-related issues may occur after surgery. Early recognition and management of these complications are important for optimal recovery.

Lifestyle & Prevention

Preventive measures include maintaining bone health through adequate calcium and vitamin D intake, regular weight-bearing exercise, and fall prevention strategies (e.g., home safety modifications). For high-risk individuals, protective gear during sports or activities may reduce injury risk. Avoiding excessive alcohol and smoking supports bone density.

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 injury also warrants evaluation. Follow up with a healthcare provider if symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Document the fracture's displacement and laterality (left acetabulum) clearly. Specify if the fracture is open or closed, and note the encounter type (e.g., initial, subsequent) for accurate coding. Include details on imaging findings, treatment provided, and any associated injuries to support code assignment. Ensure documentation aligns with clinical findings and coding guidelines.
