S32.475 Nondisplaced fracture of medial wall of left acetabulum

Name of the Condition

• Nondisplaced 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 nondisplaced fracture means the bone fragments remain in their normal alignment, which may still disrupt joint function but typically requires less invasive management compared to displaced fractures.

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 used to confirm the fracture and determine if it is nondisplaced. Additional imaging may be needed to evaluate surrounding structures.

Treatment Options

• Conservative management, including pain relief, activity modification, and physical therapy to restore mobility and strength.
• Weight-bearing restrictions or use of assistive devices (e.g., crutches) to protect the joint during healing.
• Surgical intervention is less common for nondisplaced fractures but may be considered if symptoms persist or joint stability is compromised.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, though recovery time varies. Follow-up imaging and clinical assessments are typically performed to monitor healing and ensure proper joint function. Long-term outcomes depend on fracture severity, patient age, and adherence to rehabilitation.

Complications

• Delayed healing or nonunion of the fracture.
• Post-traumatic arthritis due to joint damage.
• Nerve or blood vessel injury in severe cases.
• Chronic pain or reduced hip mobility.

Lifestyle & Prevention

• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in regular weight-bearing exercise to strengthen bones.
• Use protective gear during high-risk activities (e.g., sports, construction work).
• Fall prevention strategies for older adults, such as home modifications and balance training.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible deformity. Follow up with a healthcare provider if pain worsens, swelling persists, or mobility does not improve with conservative care.

Tips for Medical Coders

Document the specific location (left acetabulum) and fracture type (nondisplaced) to ensure accurate coding. Include details on trauma mechanism, imaging findings, and treatment approach to support code assignment. Verify that the fracture is confined to the medial wall and not associated with displacement or other pelvic injuries.
