[Hip dysplasia: clinical assessment, radiologic evaluation and reference].

Hip dysplasia is a common congenital disorder, and identified as a source of pain, functional impairment and increased risk for development of osteoarthritis. Early diagnosis and reference is essential in symptomatic hip dysplasia, since patients may be candidates for joint preserving surgery. Assessment concentrates on history, physical examination and plain radiography. If radiography confirms the diagnosis (CE-angle < 25 degrees), the patient should be referred for expert evaluation. The assessment of hip dysplasia should be well-known to GPs, orthopaedics and radiologists.
