Name of the Condition

Unspecified physeal fracture of upper end of left femur, subsequent encounter for fracture with nonunion

Summary

An unspecified physeal fracture of the upper end of the left femur is a break at the growth plate (physis) of the femur, typically occurring in children or adolescents. This injury affects the area where bone growth occurs and may involve the femoral head or neck region. The term "unspecified" indicates that the exact type or location of the fracture within the physis is not detailed. The "subsequent encounter for fracture with nonunion" specifies that this is a follow-up visit for a fracture that has failed to heal properly.

Causes

Physeal fractures of the femur are usually caused by acute trauma, such as falls, sports injuries, or direct impacts to the hip or thigh. The force transmitted through the growth plate can disrupt its structure, leading to a fracture. Nonunion may result from inadequate immobilization, poor blood supply, infection, or excessive movement during healing.

Risk Factors

• Common in children and adolescents due to the presence of active growth plates.
• Increased risk during growth spurts when growth plates are weaker.
• Participation in high-impact activities or sports that involve sudden stops or changes in direction.
• Factors that impair healing, such as smoking, diabetes, or nutritional deficiencies.

Symptoms

• Persistent pain and tenderness around the hip or upper thigh.
• Swelling or bruising in the affected area.
• Difficulty bearing weight on the leg or walking.
• Limited range of motion in the hip joint.
• Possible deformity or instability if the fracture has not healed.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging, typically X-rays, is used to identify the fracture and evaluate the alignment of the growth plate. Additional imaging, such as CT or MRI, may be used to assess for nonunion or other complications. Blood tests may be performed to rule out infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment depends on the severity of the nonunion and may include immobilization with a cast or brace, surgical intervention to realign and stabilize the fracture, bone grafting to promote healing, or physical therapy to restore function. Pain management and addressing underlying risk factors are also important.

Prognosis and Follow-Up

Prognosis varies based on the extent of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Long-term outcomes may include reduced mobility or chronic pain if the fracture does not heal properly.

Complications

• Chronic pain or discomfort.
• Limited mobility or joint stiffness.
• Increased risk of future fractures.
• Potential for growth disturbances if the growth plate is affected.
• Infection or other surgical complications if intervention is required.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed immobilization and rehabilitation protocols.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking and manage chronic conditions that may impair healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility decreases. Contact a healthcare provider if signs of infection, such as fever or redness, develop, or if the fracture does not show signs of healing over time.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with nonunion. Ensure clinical notes specify the fracture's location (upper end of left femur) and the presence of nonunion. Include details on treatment provided and any imaging or diagnostic findings to support the code.
