S72.061P Displaced articular fracture of head of right femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Displaced articular fracture of head of right femur, subsequent encounter for closed fracture with malunion

Summary

A displaced articular fracture of the head of the right femur involves a break in the femoral head (the ball portion of the hip joint) with displacement of the bone fragments. This injury affects the articular surface, which is critical for smooth joint movement. The fracture is classified as closed (no open wound) and is documented as a subsequent encounter, indicating follow-up care for a previously treated fracture. Malunion refers to improper healing of the fracture, where the bone fragments have aligned incorrectly. This condition requires evaluation to assess functional impact and guide management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Direct force to the hip region. Malunion may result from inadequate initial treatment, poor bone healing, or insufficient immobilization.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Inadequate initial fracture management or non-compliance with treatment

Symptoms

• Persistent hip or groin pain, especially with movement
• Difficulty bearing weight on the affected leg
• Altered gait or limping
• Limited range of motion in the hip joint
• Possible leg length discrepancy or deformity
• Stiffness or discomfort during daily activities

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture site and assess malunion. Comparison with prior imaging to evaluate healing progress. Functional assessments to determine impact on daily activities.

Treatment Options

• Pain management with medications or physical therapy
• Orthopedic evaluation to determine if surgical correction is needed
• Possible revision surgery to realign the femoral head (e.g., osteotomy)
• Assistive devices (e.g., crutches, walkers) to reduce weight-bearing stress
• Rehabilitation to improve strength and mobility
• Monitoring for complications or further healing issues

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Some patients may experience chronic pain or limited mobility, while others may regain near-normal function with treatment. Regular follow-up appointments are necessary to monitor healing and adjust management. Long-term outcomes may include arthritis or reduced joint function if malunion persists.

Complications

• Chronic hip pain or stiffness
• Post-traumatic arthritis
• Reduced range of motion
• Leg length discrepancy
• Increased risk of future fractures
• Need for additional surgical intervention

Lifestyle & Prevention

• Engage in weight-bearing exercises to maintain bone density (if appropriate)
• Use fall prevention strategies (e.g., home modifications, balance training)
• Ensure adequate calcium and vitamin D intake
• Avoid high-impact activities that may stress the hip joint
• Follow post-treatment guidelines to support proper healing
• Maintain a healthy weight to reduce joint stress

When to Seek Professional Help

Seek immediate medical attention if you experience sudden, severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, swelling). Contact your healthcare provider if pain worsens, mobility declines, or you notice new deformities. Regular follow-up is essential for monitoring malunion and adjusting treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with malunion. Include details on the fracture's location (right femur head), displacement, and healing status. Note any functional limitations or treatment modifications. Ensure documentation supports the malunion diagnosis and subsequent encounter timing.
