M89.154 Partial physeal arrest, left proximal femur

Name of the Condition

• Partial physeal arrest, left proximal femur

Summary

Partial physeal arrest of the left proximal femur is the incomplete cessation of growth at the growth plate (physis) of the left proximal femur, which can disrupt normal skeletal development. This condition may lead to limb length discrepancies or angular deformities, depending on the extent of growth plate involvement and the timing of arrest.

Causes

Partial physeal arrest of the left proximal femur can result from trauma, infection, radiation therapy, or certain medical conditions that damage the growth plate. It may also occur as a complication of orthopedic procedures or due to genetic disorders affecting bone growth.

Risk Factors

• Trauma to the growth plate, such as fractures or dislocations
• Infections (e.g., osteomyelitis) involving the growth plate
• Radiation therapy near the growth plate
• Underlying conditions like rickets or skeletal dysplasias
• Prior orthopedic surgeries involving the growth plate

Symptoms

• Limb length inequality (shorter left leg)
• Angular deformities (e.g., bowing or angulation of the left femur)
• Asymmetrical growth between limbs
• Pain or swelling at the affected growth plate
• Functional limitations due to deformity

Diagnosis

Diagnosis involves a physical examination to assess limb alignment and growth. Imaging studies, such as X-rays or MRI, are used to evaluate the growth plate and detect signs of partial arrest. Comparison of limb lengths and serial imaging may be necessary to confirm the diagnosis.

Treatment Options

Treatment depends on the severity of the condition and may include observation, orthotics, or surgical interventions like epiphysiodesis or osteotomy to correct deformities or equalize limb lengths.

Prognosis and Follow-Up

Prognosis varies based on the extent of growth plate involvement and the timing of intervention. Regular follow-up with imaging and clinical assessments is essential to monitor growth and adjust treatment as needed.

Complications

Potential complications include progressive limb length discrepancy, worsening angular deformities, joint instability, and functional impairment if left untreated.

Lifestyle & Prevention

Preventive measures include prompt treatment of growth plate injuries or infections, avoiding unnecessary radiation exposure, and managing underlying conditions that affect bone growth.

When to Seek Professional Help

Seek medical attention if limb length inequality, deformity, or pain develops, especially after trauma or infection, to prevent long-term complications.

Tips for Medical Coders

Document the laterality (left), specificity (partial), and anatomical location (proximal femur) to ensure accurate coding. Include clinical details supporting the diagnosis, such as imaging findings or physical exam results, to justify the code assignment.
