Q65.5 Congenital partial dislocation of hip, unspecified

Name of the Condition

• Congenital Partial Dislocation of Hip, Unspecified

Summary

Congenital partial dislocation of the hip, unspecified, is a structural abnormality of the hip joint present at birth where the femoral head is partially displaced from the acetabulum. This condition affects joint stability and may impact hip development if not addressed promptly.

Causes

The exact causes are often multifactorial, involving genetic predisposition and developmental factors during pregnancy. Intrauterine positioning, such as breech presentation, may contribute to hip deformities. Genetic factors and familial patterns are also implicated.

Risk Factors

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

Symptoms

• Asymmetry in skin folds around the thigh or buttocks
• Limited range of motion in the 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

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
• Potential for long-term functional impairment
• Increased risk of degenerative joint disease

Lifestyle & Prevention

• Routine newborn hip screening to detect abnormalities early
• Proper positioning techniques for infants to support hip development
• Avoidance of restrictive devices that may exacerbate displacement

When to Seek Professional Help

Seek medical evaluation if asymmetry in skin folds, limited hip movement, or abnormal gait is observed in an infant. Prompt assessment is essential for effective management.

Tips for Medical Coders

Document the clinical findings supporting the diagnosis, including physical examination results and imaging studies. Ensure the unspecified nature of the partial dislocation is clearly noted, as this may impact coding specificity.
