S72.111M Displaced fracture of greater trochanter of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced fracture of greater trochanter of right femur, subsequent encounter for open fracture type I or II with nonunion

Summary

This condition describes a displaced fracture of the greater trochanter of the right femur, occurring during a subsequent encounter for an open fracture classified as type I or II, with nonunion. The greater trochanter is a bony prominence on the upper femur near the hip joint. Displacement means the bone fragments are not aligned, an open fracture indicates the bone has pierced the skin (increasing infection risk), and nonunion refers to the failure of the fracture to heal properly. This type of injury typically results from trauma and requires ongoing medical management.

Causes

Displaced fractures of the greater trochanter often result from direct trauma, such as falls, motor vehicle accidents, or high-impact injuries. Open fractures occur when the broken bone penetrates the skin, exposing the fracture site. Nonunion may develop due to inadequate immobilization, poor blood supply to the bone, infection, or underlying conditions that impair healing (e.g., diabetes, smoking, or nutritional deficiencies).

Risk Factors

• Advanced age, particularly in individuals with osteoporosis or reduced bone density.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or falls.
• Sedentary lifestyle or limited mobility, which can contribute to bone weakness.
• High-impact activities or occupations increasing fracture risk.
• Factors that impair healing, such as smoking, diabetes, or poor nutrition.

Symptoms

• Persistent hip or groin pain, often worsened by movement or weight-bearing.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Possible signs of infection (e.g., redness, warmth, or drainage) if the fracture is open.
• Lack of healing progress over time, indicating nonunion.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture, evaluate displacement, and assess for nonunion. Additional tests (e.g., blood work) may be performed to check for infection or underlying conditions affecting healing.

Treatment Options

Treatment focuses on promoting healing and managing complications. Options may include surgical intervention (e.g., internal fixation) to stabilize the fracture, antibiotics for open fractures to prevent infection, and bone grafting or other procedures to address nonunion. Rehabilitation, including physical therapy, is often necessary to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the presence of nonunion. Follow-up care is essential to monitor healing, address complications, and adjust treatment as needed. Long-term outcomes may include persistent pain, limited mobility, or the need for additional interventions if nonunion persists.

Complications

• Infection (especially with open fractures).
• Nonunion or delayed union.
• Avascular necrosis (loss of blood supply to the bone).
• Chronic pain or arthritis in the hip joint.
• Muscle weakness or atrophy.
• Reduced mobility or functional impairment.

Lifestyle & Prevention

• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in weight-bearing exercises to strengthen bones.
• Avoid high-impact activities that increase fracture risk.
• Use protective measures (e.g., hip pads) for individuals at high risk of falls.
• Quit smoking and limit alcohol, as these can impair bone healing.
• Manage underlying conditions (e.g., osteoporosis) with appropriate medical care.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or signs of infection (e.g., fever, drainage, or redness). Follow up with a healthcare provider if pain persists, swelling worsens, or there are concerns about healing progress.

Tips for Medical Coders

Document the encounter type (subsequent), fracture type (open I or II), and nonunion status clearly. Ensure clinical notes specify the fracture’s displacement, open nature, and failure to unite. Code S72.111M is appropriate for this scenario; verify documentation aligns with the code’s definition to support accurate coding.
