Q65.3 Congenital partial dislocation of hip, unilateral

Name of the Condition

• Congenital Partial Dislocation of Hip, Unilateral

Summary

Congenital partial dislocation of the hip, unilateral, is a condition present at birth where the femoral head is not fully seated in the acetabulum of one hip. This results in joint instability and can affect hip development if untreated.

Causes

The exact cause is not fully understood, but it may involve genetic factors, intrauterine positioning, or abnormal fetal development. A family history of hip dysplasia can increase risk.

Risk Factors

• Female gender
• Breech birth position
• Family history of hip dysplasia
• Firstborn status
• Oligohydramnios (reduced amniotic fluid)

Symptoms

• Asymmetrical skin folds around the thigh or buttocks
• Limited range of motion in the affected hip
• Leg length discrepancy
• Clicking or popping sounds during hip movement
• Limp or abnormal gait in older infants

Diagnosis

Physical examination, including tests for hip stability and range of motion, is the initial step. Imaging studies like ultrasound (for infants) or X-rays (for older children) confirm structural abnormalities. Early screening is critical for timely intervention.

Treatment Options

• Pavlik harness or similar orthotic devices for infants to stabilize the hip
• Closed or open surgical procedures for older children or if conservative measures fail

Prognosis and Follow-Up

Early diagnosis and treatment improve outcomes. Regular follow-up is needed to monitor hip development and address any residual issues.

Complications

• Untreated cases may lead to chronic hip instability
• Increased risk of arthritis in adulthood
• Persistent gait abnormalities

Lifestyle & Prevention

• Routine newborn hip screening during pediatric visits
• Avoiding restrictive swaddling that limits hip movement
• Maintaining proper positioning for infants (e.g., avoiding forced leg extension)

When to Seek Professional Help

Seek medical evaluation if you notice asymmetry in skin folds, limited hip movement, or a limp in your child. Early intervention is key to preventing long-term complications.

Tips for Medical Coders

Document the laterality (unilateral) and specify "partial dislocation" to distinguish from complete dislocation. Include details on diagnostic methods (e.g., physical exam, imaging) and treatment approaches for accurate coding. Ensure documentation supports the clinical findings and management plan.
