Figure A and B are radiographs of a 77-year-old patient presenting with right hip and upper thigh pain for the past 3 months. He is an avid golfer and plans to travel south for 6 months on a golf tour. He denies fever, chills or weight loss. His past medical history includes hypertension and a right total hip replacement 15 years ago. Physical examination reveals minimal pain with range of motion. ESR=10 (normal range 0-20) and CRP=4 (normal range 0-10). He does not want any further surgery. The patient is at the highest risk of which complication with non-operative care?
Periprosthetic femoral fracture
Periprosthetic acetabular fracture

Which of the following statements best describes results that have been reported with roentgen stereophotogrammetric analysis (RSA)?
Cemented total hip stems do not migrate.
Well-fixed total hip stems (cemented or cementless) migrate approximately 3 degrees and 5 mm in the first year.
Any early migration (ie, greater than 0 mm less than 6 months after surgery) portends failure of the component.
Migration greater than 1 mm to 2 mm in the first year is associated with a higher risk of loosening.
