A 48-year-old male is referred to your clinic for progressive left hip and thigh pain for the past three weeks. His pain is causing him to walk with a significant limp and he is no longer able to do his job as a carpenter. Two months ago, he found a lump in his neck, however, he never saw his doctor due to concerns about missing work. A radiograph obtained in your office is shown in Figure A. A biopsy slide obtained from the lesion is shown in Figure B. What is this patient's Mirel's score, and what would be the next best step in treatment?
