S72.133M Displaced apophyseal fracture of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced apophyseal fracture of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A displaced apophyseal fracture of the unspecified femur, subsequent encounter for open fracture type I or II with nonunion, is a break in the apophysis (a bony growth area) of the femur where the bone fragments are separated from their normal position. The fracture is open (exposing the bone to the external environment) with minimal or moderate soft tissue damage, and nonunion indicates the fracture has failed to heal properly. This type of fracture typically results from trauma and requires ongoing medical management due to the open nature of the injury and healing complications.

Causes

Apophyseal fractures commonly result from direct trauma, such as falls, high-impact injuries, or accidents. Open fractures may occur when the broken bone pierces the skin or when external force causes a wound over the fracture site. Nonunion can develop due to inadequate immobilization, poor blood supply, infection, or underlying conditions that impair bone healing.

Risk Factors

• Adolescence, especially during growth spurts.
• Participation in high-impact sports or activities.
• History of previous hip or thigh injuries.
• Underlying bone conditions that weaken the apophysis.
• Trauma involving significant force or open wounds.
• Factors contributing to nonunion, such as smoking, diabetes, or nutritional deficiencies.

Symptoms

• Persistent localized pain at the hip or thigh, often severe and worsened by movement.
• Swelling, tenderness, or bruising around the affected area.
• Difficulty bearing weight on the leg.
• Possible limping or altered gait.
• Signs of nonunion, such as persistent pain or instability at the fracture site.

Diagnosis

Physical examination to assess pain, swelling, and tenderness. Imaging studies, including X-rays or MRI, to confirm the fracture, evaluate displacement, and assess for nonunion. Evaluation of the open wound to determine fracture type (I or II) and check for infection or soft tissue damage.

Treatment Options

Treatment focuses on promoting healing and managing the open fracture. This may include surgical intervention to stabilize the fracture, debridement of the wound, and antibiotics to prevent infection. Nonunion may require additional procedures, such as bone grafting or revision surgery. Immobilization with a cast or brace, physical therapy, and pain management are also part of the care plan.

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. Regular imaging and clinical assessments help track progress and ensure the fracture heals properly.

Complications

• Nonunion or delayed healing.
• Infection at the fracture site or open wound.
• Chronic pain or instability.
• Nerve or vascular damage.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed immobilization and weight-bearing restrictions.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective gear during sports or activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or signs of infection (e.g., fever, redness, drainage). Contact your healthcare provider if pain worsens, mobility decreases, or you notice new symptoms, as these may indicate complications like nonunion or infection.

Tips for Medical Coders

Document the fracture type (open type I or II), the presence of nonunion, and the subsequent encounter status clearly. Ensure the unspecified femur is appropriately coded and that all relevant details about the fracture and healing status are included in the medical record.
