Name of the Condition

Salter-Harris Type I physeal fracture of upper end of unspecified femur, subsequent encounter for fracture with nonunion

Summary

A Salter-Harris Type I fracture is an injury to the growth plate (physis) where the physis separates from the adjacent bone without involving the metaphysis or epiphysis. This specific fracture occurs at the upper end of the femur, typically in children or adolescents. The injury disrupts the area responsible for longitudinal bone growth and may result from acute trauma. The term "subsequent encounter for fracture with nonunion" indicates this is a follow-up visit for a fracture that has not healed properly.

Causes

Usually caused by acute trauma, such as falls, sports-related injuries, or direct blows to the hip or thigh. The force transmitted across the growth plate can cause it to separate from the femur.

Risk Factors

• Common in children and adolescents due to weaker growth plates relative to surrounding bone.
• Increased risk during growth spurts when the physis is more susceptible to injury.
• Participation in high-impact activities or sports with a risk of falls or collisions.

Symptoms

• Persistent pain and tenderness around the hip or upper thigh.
• Swelling and possible bruising in the affected area.
• Difficulty bearing weight on the leg or walking.
• Limited range of motion in the hip joint.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging, typically X-rays, is used to confirm the fracture and evaluate the alignment of the growth plate. In cases of nonunion, additional imaging or advanced studies may be needed to assess healing progress.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, physical therapy to restore function, and in some cases, surgical intervention to stabilize the fracture. Management of nonunion may require specialized orthopedic care.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Regular follow-up appointments are necessary to monitor healing and adjust treatment plans as needed. Long-term outcomes may vary based on the extent of the injury and adherence to rehabilitation.

Complications

• Delayed or impaired bone growth due to damage to the growth plate.
• Chronic pain or instability in the hip joint.
• Increased risk of future fractures in the affected area.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Follow rehabilitation guidelines to support healing and prevent complications.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility does not improve. Prompt evaluation is important if signs of infection, such as fever or increased redness, develop.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with nonunion. Ensure clinical documentation specifies the fracture type (Salter-Harris Type I), location (upper end of femur), and the presence of nonunion. Include details about the treatment provided and the patient’s response to therapy.
