S72.115P Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with malunion

Summary

A nondisplaced fracture of the greater trochanter of the left femur is a break in the bony prominence on the upper part of the left thigh bone (femur) near the hip joint, where the bone fragment remains in its normal position. This type of fracture is classified as a subsequent encounter for a closed fracture with malunion, indicating that the fracture has healed in an abnormal position without an open wound. The condition typically results from trauma or weakened bone structure and requires ongoing management to address the malunion.

Causes

Nondisplaced 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 without displacement. Malunion may develop if the fracture heals improperly, often due to inadequate immobilization or underlying bone health issues.

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 immobilization.

Symptoms

• Persistent hip or groin pain, often worsened by movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Functional limitations due to malunion.

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 malunion. Review of prior treatment and healing history to determine the fracture's status.

Treatment Options

• Pain management with medications or physical therapy.
• Orthopedic evaluation to assess the need for corrective surgery or rehabilitation.
• Weight-bearing restrictions or assistive devices to reduce stress on the affected area.
• Monitoring for functional improvement or complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the malunion and the patient's overall health. Follow-up care may include regular imaging to assess healing and functional outcomes. Long-term management may focus on preventing further injury or addressing mobility issues.

Complications

• Chronic pain or discomfort.
• Reduced mobility or functional impairment.
• Increased risk of future fractures due to underlying bone weakness.
• Potential need for surgical intervention if malunion causes significant symptoms.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones, if appropriate.
• Use fall prevention strategies, such as home modifications or assistive devices.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Avoid high-impact activities that may increase fracture risk.

When to Seek Professional Help

Seek medical attention if you experience severe or worsening pain, inability to bear weight, or signs of infection (e.g., fever, redness, swelling). Prompt evaluation is important for managing malunion and preventing complications.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with malunion. Include details on the fracture's healing status, any functional impact, and treatment provided. Ensure documentation supports the malunion diagnosis and subsequent encounter context.
