Leg Length Discrepancy (Overview)

Leg length discrepancy occurs when a person's legs are of unequal lengths due to differences in the bones of the thigh, shin, or both. While mild differences may go unnoticed, significant discrepancies can lead to limping, pain, or long-term complications like arthritis. These conditions may arise at birth (congenital) or develop later in life (acquired) due to injuries or unknown causes. Early diagnosis and appropriate treatment are essential for managing this condition effectively.

What Does Leg Length Discrepancy Treat?

Treatment for leg length discrepancy is tailored to the severity of the difference. Options include:

• Shoe lifts for minor differences.
• Epiphysiodesis to slow the growth of the longer leg in children who are still growing.
• Surgical shortening of the longer leg for children or adults who have stopped growing.
• Limb lengthening surgeries to extend the shorter leg using advanced devices like external fixators or internal lengthening rods.

Leg Length Discrepancy Treatment Process: How Does It Work?

Diagnosis: The orthopedic team measures leg lengths, observes gait, and performs X-rays.

Customized Plan: The treatment is chosen based on the child’s age, growth potential, and severity of the discrepancy.

Procedures: Treatment may involve shoe lifts, minimally invasive surgery like epiphysiodesis, or complex surgeries for shortening or lengthening the bones.

Follow-up: Post-surgical rehabilitation and regular medical visits are essential for monitoring progress and ensuring proper healing.

Good Candidates for Leg Length Discrepancy Treatment

A good candidate for leg length discrepancy treatment typically meets the following criteria:

• Children with congenital conditions like fibular hemimelia or focal femoral deficiency.
• Individuals with significant acquired leg length discrepancies due to injury or infections.
• Patients with differences exceeding 1 inch (2.5 cm) require surgical intervention.
• Those committed to follow-up care and rehabilitation for surgical procedures.
