Q65.31 Congenital partial dislocation of right hip, unilateral

Name of the Condition

• Congenital Partial Dislocation of Right Hip, Unilateral

Summary

Congenital partial dislocation of the right hip, unilateral, is a condition present at birth where the femoral head is not fully seated in the acetabulum of the right hip. This results in joint instability and can affect hip development if untreated. The condition is typically identified in newborns or infants and may require intervention to prevent long-term complications.

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 deformities
• Firstborn status
• Oligohydramnios (reduced amniotic fluid)

Symptoms

• Asymmetrical skin folds around the right thigh or buttock
• Limited range of motion in the right hip
• Leg length discrepancy (right leg shorter)
• 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 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. Untreated cases may lead to chronic hip instability or arthritis.

Complications

• Chronic hip instability
• Early-onset arthritis
• Gait abnormalities
• Leg length discrepancy

Lifestyle & Prevention

• Routine newborn screening for hip stability
• Avoiding forced hip positioning in infants
• Prompt evaluation of suspected cases

When to Seek Professional Help

Seek medical attention if asymmetry in skin folds, limited hip movement, or a limp is observed. Early intervention is key to preventing complications.

Tips for Medical Coders

Document the laterality (right hip) and unilateral nature of the condition. Ensure clinical notes support the diagnosis and specify if the dislocation is partial. Follow coding guidelines for congenital hip deformities to ensure accurate reporting.
