S79.122S Salter-Harris Type II physeal fracture of lower end of left femur, sequela

Name of the Condition

Salter-Harris Type II physeal fracture of lower end of left femur, sequela

Summary

A Salter-Harris Type II physeal fracture of the lower end of the left femur, sequela, refers to the residual effects of a previous injury involving the growth plate (physis) at the distal femur. This type of fracture disrupts the physis and includes a metaphyseal fragment, as defined by the Salter-Harris classification system. The term "sequela" indicates that the condition represents a complication or long-term consequence of the initial fracture, such as chronic pain, deformity, or functional impairment resulting from incomplete healing or growth disturbance.

Causes

Salter-Harris Type II physeal fractures of the lower femur are typically caused by acute trauma, such as falls, sports-related injuries, or direct blows to the knee or thigh. The force transmitted across the growth plate can cause it to separate from the adjacent bone, often with a small piece of the metaphysis attached. Sequela may develop if the initial injury was not properly treated, leading to malunion, growth arrest, or persistent instability.

Risk Factors

• Age: Most common in children and adolescents, as growth plates are weaker than surrounding bone.
• Activity level: Participation in high-impact sports or activities with a risk of falls (e.g., gymnastics, soccer, skateboarding).
• Inadequate initial treatment: Improper management of the original fracture may increase the risk of long-term complications.

Symptoms

• Chronic pain or discomfort in the knee or thigh area.
• Visible deformity or limb length discrepancy.
• Reduced range of motion or stiffness in the affected joint.
• Functional limitations, such as difficulty walking or bearing weight.

Diagnosis

Diagnosis of sequela typically involves a thorough clinical evaluation, including a review of the patient's medical history and the original injury. Imaging studies, such as X-rays or MRI, may be used to assess residual bone damage, growth plate integrity, or associated deformities. The presence of persistent symptoms following the initial fracture, combined with imaging findings, helps confirm the diagnosis.

Treatment Options

Treatment focuses on managing symptoms and addressing functional impairments. Options may include physical therapy to improve strength and mobility, pain management strategies, or surgical intervention to correct deformities or stabilize the growth plate. The approach depends on the severity of the sequela and the impact on the patient's quality of life.

Prognosis and Follow-Up

Prognosis varies based on the extent of the initial injury and the effectiveness of treatment. Some patients may experience minimal long-term effects, while others may have persistent limitations. Regular follow-up with an orthopedic specialist is recommended to monitor growth, function, and the need for further intervention.

Complications

• Growth arrest or limb length discrepancy.
• Chronic pain or arthritis.
• Deformity or angular malalignment.
• Reduced mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities that may exacerbate symptoms.
• Engage in low-impact exercises, such as swimming or cycling, to maintain mobility.
• Use protective gear during sports to reduce the risk of future injuries.
• Follow post-treatment guidelines to support healing and prevent recurrence.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new deformity, or significant functional limitations. Early evaluation can help address complications and improve outcomes.

Tips for Medical Coders

When coding for Salter-Harris Type II physeal fracture of the lower end of the left femur, sequela, ensure the documentation clearly indicates the condition is a residual effect of a prior injury. Verify that the term "sequela" is appropriately used and supported by clinical findings or a history of the original fracture. Accurate coding requires linking the sequela to the initial injury and confirming the absence of active healing or acute symptoms.
