S72.112M Displaced fracture of greater trochanter of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced fracture of greater trochanter of left femur, subsequent encounter for open fracture type I or II 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 applies to a subsequent encounter for an open fracture (type I or II) that has failed to heal (nonunion). Open fractures involve a break in the skin with minimal to moderate soft tissue damage, and nonunion indicates the fracture has not united after an expected healing period.

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. Open fractures may result from trauma that penetrates the skin, such as a fall onto a sharp object or a high-velocity injury. Nonunion can develop due to inadequate stabilization, poor blood supply, infection, or excessive movement at the fracture site.

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.
• Trauma involving open wounds, such as motor vehicle accidents or falls onto sharp surfaces.
• Factors contributing to nonunion, including smoking, diabetes, or inadequate initial treatment.

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 nonunion, such as persistent pain or lack of healing progress.
• Open wound or soft tissue damage (for open fracture types I or II).

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. Assessment of the open wound (for type I or II) to determine soft tissue damage. Evaluation of healing progress through serial imaging and clinical follow-up.

Treatment Options

• Stabilization with surgical fixation (e.g., screws, plates) to promote union.
• Management of the open wound, including cleaning and possible debridement.
• Non-weight-bearing or protected weight-bearing as advised.
• Pain management and physical therapy to restore function.
• Bone grafting or other interventions if nonunion persists.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adequacy of treatment, and patient factors. Nonunion may require additional interventions, and recovery can be prolonged. Regular follow-up with imaging and clinical assessments is necessary to monitor healing. Physical therapy is often needed to regain strength and mobility.

Complications

• Nonunion or delayed union.
• Infection (especially with open fractures).
• Avascular necrosis of the femoral head.
• Chronic pain or arthritis.
• Leg length discrepancy.
• Reduced mobility or functional impairment.

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake.
• Engage in weight-bearing exercise to strengthen bones.
• Use fall prevention strategies, such as home modifications and assistive devices.
• Avoid high-risk activities that may lead to trauma.
• Manage underlying conditions like osteoporosis to reduce fracture risk.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, visible deformity, or open wounds. Follow up with a healthcare provider if pain persists, swelling increases, or there are signs of infection (e.g., fever, redness, drainage).

Tips for Medical Coders

Document the fracture type (open I or II), laterality (left femur), and the presence of nonunion. Specify the encounter as "subsequent" and note any relevant details about the open wound or healing status. Ensure documentation supports the nonunion diagnosis and aligns with the code's requirements for open fracture classification.
