Syndrome of symptomatic adult acetabular dysplasia (SAAD syndrome).

OBJECTIVES

To determine the prevalence of acetabular dysplasia in subjects presenting with hip pain to primary care and its relationship with radiographic osteoarthritis (OA) of the hip.

DESIGN

Cross sectional analysis of a prospective cohort.

SETTING

35 general practices across the UK.

SUBJECTS: 195 patients (63 male, 132 female) aged 40 years and over presenting with a new episode of hip pain

RESULTS

The prevalence of acetabular dysplasia in this study of new presenters with hip pain was high (32%). There was no significant relationship between acetabular dysplasia and radiographic OA overall.

CONCLUSIONS

The high prevalence of acetabular dysplasia across all grades of OA severity suggests that dysplasia itself may be an important cause of hip pain ("symptomatic adult acetabular dysplasia").
