S72.112K Displaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with nonunion

Summary

A displaced 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 has moved out of its normal position. This code represents a subsequent encounter for a closed fracture that has failed to heal (nonunion) after an initial injury. Nonunion occurs when the bone does not properly fuse during the healing process, often requiring additional medical intervention.

Causes

Displaced fractures of the greater trochanter typically result from direct trauma, such as falls or high-impact injuries. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, infection, or underlying conditions that impair bone healing, such as diabetes or smoking. In some cases, the initial fracture may have been severe or displaced, increasing the risk of nonunion.

Risk Factors

• Advanced age, particularly in individuals with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or delayed healing.
• Smoking or poor nutrition, which can impair bone repair.
• Inadequate initial treatment or immobilization of the fracture.

Symptoms

• Persistent hip or groin pain, often lasting beyond the typical healing period.
• Inability to bear weight on the affected leg.
• Swelling or tenderness at the fracture site.
• Limited range of motion in the hip joint.
• Possible deformity or instability in the hip area.

Diagnosis

Diagnosis involves a physical examination to assess pain, mobility, and deformity. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate for nonunion, which is typically identified by a visible gap at the fracture site or lack of bone healing over time. Additional tests, like bone scans, may be performed to assess blood flow and healing potential.

Treatment Options

Treatment focuses on promoting bone union and restoring function. Options may include surgical intervention, such as internal fixation with screws or plates, bone grafting to stimulate healing, or external fixation devices. Non-surgical approaches, like prolonged immobilization or electrical stimulation, may be considered for less severe cases. Physical therapy is often recommended to improve strength and mobility.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With appropriate intervention, many patients achieve successful healing and restored function, though recovery may be prolonged. Regular follow-up with imaging studies is necessary to monitor progress. Long-term outcomes may include reduced mobility or chronic pain if healing is incomplete.

Complications

• Chronic pain or discomfort at the fracture site.
• Persistent instability or deformity in the hip.
• Increased risk of future fractures due to weakened bone.
• Potential need for additional surgeries if initial treatment fails.
• Reduced quality of life due to limited mobility.

Lifestyle & Prevention

• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Engage in weight-bearing exercises to strengthen bones, as advised by a healthcare provider.
• Avoid smoking and limit alcohol, which can impair bone healing.
• Use assistive devices, such as canes or walkers, to reduce fall risk, especially in older adults.
• Follow post-treatment guidelines for activity restrictions and rehabilitation.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, swelling, or inability to bear weight on the affected leg. Contact a healthcare provider if you notice signs of infection, such as fever, redness, or drainage from the hip area, or if symptoms persist beyond the expected healing timeline.

Tips for Medical Coders

This code (S72.112K) is used for a subsequent encounter of a closed fracture of the greater trochanter of the left femur with nonunion. Document the encounter type (subsequent) and confirm the fracture is closed (no open wound) and has not healed. Ensure documentation supports the nonunion diagnosis, including imaging findings or clinical assessment of delayed healing.
