S72.113P Displaced fracture of greater trochanter of unspecified femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Displaced fracture of greater trochanter of unspecified femur, subsequent encounter for closed fracture with malunion

Summary

A displaced fracture of the greater trochanter of the femur is a break in the bony prominence on the upper part of the thigh bone (femur) near the hip joint, where the bone fragment has moved out of its normal position. This type of fracture is classified as a subsequent encounter for a closed fracture with malunion, indicating it is a follow-up visit for a previously treated fracture that has healed in an abnormal position without an open wound. The term "unspecified femur" means the side (right or left) is not documented.

Causes

Displaced fractures of the greater trochanter commonly result from direct trauma, such as falls or high-impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture with displacement. Malunion may develop if the initial fracture was not properly aligned during healing or if the bone heals in an abnormal position.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or falls.
• Sedentary lifestyle or limited mobility.
• Inadequate initial fracture management or non-compliance with treatment.

Symptoms

• Persistent hip or groin pain, often worsened by movement.
• Difficulty bearing weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Reduced range of motion in the hip joint.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture and evaluate the extent of malunion. Comparison with prior imaging may be used to assess healing progress.

Treatment Options

• Pain management with medications or physical therapy.
• Orthopedic evaluation to determine if realignment or surgical intervention is needed.
• Rehabilitation exercises to improve mobility and strength.
• Monitoring for functional limitations or complications.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Follow-up care focuses on managing symptoms, restoring mobility, and preventing further complications. Regular imaging may be used to assess healing and guide treatment adjustments.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures.
• Potential need for surgical correction if malunion causes significant functional impairment.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones.
• Ensure adequate calcium and vitamin D intake.
• Use assistive devices (e.g., canes, walkers) to reduce fall risk.
• Maintain a healthy weight to minimize stress on bones.
• Follow post-fracture care instructions to support proper healing.

When to Seek Professional Help

Seek medical attention if you experience severe or worsening pain, inability to bear weight, new swelling, or signs of infection (e.g., fever, redness). Prompt evaluation is important if malunion symptoms interfere with daily activities.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with malunion. Ensure clinical notes specify the fracture type, healing status, and any functional limitations. Verify that the code aligns with the patient's current condition and treatment phase.
