Q66.52 Congenital pes planus, left foot

Name of the Condition

• Congenital Pes Planus, Left Foot
• Commonly referred to as flatfoot or fallen arches when present in both feet.

Summary

Congenital pes planus is a condition present at birth where the left foot has an abnormally low or absent arch, causing the entire sole to make contact with the ground. It may occur in isolation or alongside other foot deformities and is often asymptomatic in early childhood.

Causes

The exact cause is not fully understood but may involve genetic factors affecting bone and ligament development in the foot. Intrauterine positioning or familial predisposition can also play a role.

Risk Factors

• Family history of flat feet.
• Genetic conditions impacting musculoskeletal development.
• Intrauterine constraints during pregnancy.

Symptoms

• Visibly flattened arch when standing.
• Possible shoe-fitting difficulties.
• Pain or discomfort in the foot, ankle, or lower leg during activity (if symptomatic).
• Feet turning outward while walking.

Diagnosis

Diagnosis is typically made through physical examination to assess foot alignment and arch formation. Imaging studies like X-rays may be used to evaluate bone structure if deformity or associated issues are suspected.

Treatment Options

• Often no treatment is necessary for asymptomatic cases.
• Orthotic devices or specially designed footwear for arch support.
• Physical therapy to strengthen foot and ankle muscles.
• Surgery in severe cases with significant pain or functional limitations.

Prognosis and Follow-Up

Many children with congenital pes planus develop a normal arch as they grow. Regular follow-up may be recommended for symptomatic cases or those with associated alignment issues.

Complications

• Chronic foot, ankle, or lower leg pain.
• Altered gait or balance problems.
• Increased risk of other foot or ankle injuries.

Lifestyle & Prevention

• Choose supportive footwear with good arch support.
• Maintain a healthy weight to reduce foot stress.
• Engage in regular low-impact exercise to strengthen foot muscles.

When to Seek Professional Help

Consult a healthcare provider if pain, difficulty walking, or worsening symptoms occur. Early evaluation is recommended if the condition affects daily activities or causes discomfort.

Tips for Medical Coders

Document the specific foot affected (left) and any associated symptoms or interventions. Ensure clinical notes support the diagnosis and specify whether the condition is isolated or part of a broader deformity.
