MechanicalCharacteristics of DDH * Static overload of rim: local stress concentration * Dynamic instability: shear forces
Clinical Evaluation of the Patient with Hip Instability • History/Sx: early--trochanteric ache or limp – Groin ache is a later symptom of rim overload – Acetabular rim syndrome: sharp pain, instability * Other dysplasia symptoms are from anterior instability and are often worst when hip is extended or externally rotated * NB: Most impinging hips are most symptomatic in flexion.
