S32.476S Nondisplaced fracture of medial wall of unspecified acetabulum, sequela

Name of the Condition

• Nondisplaced fracture of medial wall of unspecified acetabulum, sequela

Summary

This condition represents a sequela (late effect) of a previously sustained nondisplaced fracture of the medial wall of the acetabulum, the socket portion of the hip joint. The acetabulum is part of the pelvic bone and is critical for hip stability and movement. A nondisplaced fracture means the bone fragments remained aligned during the initial injury, but the sequela indicates ongoing effects or complications from that prior fracture. Management focuses on addressing residual symptoms, restoring function, and preventing further joint damage.

Causes

The sequela arises from a prior nondisplaced fracture of the medial acetabular wall, typically caused by high-impact trauma (e.g., motor vehicle accidents, falls from height) or, less commonly, low-impact events in individuals with weakened bones (e.g., osteoporosis). The current condition reflects the long-term consequences of that initial injury.

Risk Factors

• Advanced age, as bone density naturally decreases.
• Osteoporosis or other bone-weakening conditions.
• Prior hip or pelvic injuries.
• Conditions affecting bone healing or joint integrity.

Symptoms

• Chronic hip or groin pain, often persistent or recurrent.
• Reduced range of motion in the hip joint.
• Difficulty bearing weight on the affected leg.
• Possible joint stiffness or instability.
• Swelling or tenderness in the hip area.

Diagnosis

Diagnosis involves a detailed patient history to confirm a prior acetabular fracture and a physical exam to assess hip function, pain, and mobility. Imaging studies (e.g., X-rays, CT scans) may be used to evaluate residual bone alignment, joint space, or signs of arthritis. Additional tests (e.g., MRI) can assess soft tissue or cartilage damage.

Treatment Options

Treatment focuses on symptom relief and functional restoration. Options may include physical therapy to improve strength and mobility, pain management (e.g., medications, injections), and activity modification. In some cases, surgical intervention (e.g., joint preservation or reconstruction) may be considered for severe residual dysfunction.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial fracture, the extent of residual damage, and the patient’s overall health. Most patients experience improved function with appropriate management, but some may have persistent limitations. Regular follow-up with a healthcare provider is important to monitor joint health and adjust treatment as needed.

Complications

• Post-traumatic arthritis of the hip joint.
• Chronic pain or stiffness.
• Reduced mobility or gait abnormalities.
• Potential need for future surgical intervention.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain hip strength and flexibility.
• Use assistive devices (e.g., cane, walker) if needed to reduce joint stress.
• Maintain a healthy weight to minimize hip load.
• Follow a bone-healthy diet (e.g., adequate calcium and vitamin D) to support joint integrity.

When to Seek Professional Help

Seek medical attention if you experience worsening hip pain, new swelling, difficulty walking, or signs of infection (e.g., fever, redness). Prompt evaluation is important to address complications or adjust treatment.

Tips for Medical Coders

Use this code for a sequela (late effect) of a nondisplaced fracture of the medial wall of the acetabulum. Document the prior fracture and its relationship to the current condition. Ensure the code aligns with the patient’s history and clinical findings, and verify that no other codes better describe the current status.
