This lecture provides a practical, clinically focused approach to adult hip dysplasia, with an emphasis on recognising the condition early and avoiding common diagnostic delays. It explores the typical subjective presentation, including groin and buttock pain, instability, apprehension in terminal hip extension, and associated symptoms such as low back or knee pain.

The lecture examines how acetabular version influences pain patterns, gait, hip mobility, and functional movements, and demonstrates key clinical findings associated with anteverted and retroverted hips. It also discusses appropriate rehabilitation strategies, activity modification, and criteria for escalating care to imaging.

A systematic approach to AP pelvic X-ray interpretation is presented, including the lateral centre-edge angle, Tönnis angle, and radiographic signs of acetabular version.

Main learning points:

1. Subjective signs of adult hip dysplasia

2. Objective signs

3. Rehabilitation of hip dysplasia

4. Radiographic features of dysplasia and when to request

5. Surgical options for hip dysplasia
