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.
