Q: A 64-year-old female is admitted for evaluation of increased pain in her back that has not been controlled with over-the-counter pain medication. The patient has osteoporosis, nonalcoholic cirrhosis, chronic renal failure, hypotension, and GERD with esophageal varices and is status post dramatic weight loss due to previous gastric bypass surgery. The x-ray of the thoracic spine shows a moderate compression fracture of T7. X-ray of the pelvis and right hip show possible fracture of the inferior pubic ramus, although MRI examination of the right hip did not show evidence of fracture. Discharge diagnoses: (1) Back pain secondary to vertebral compression T7 fracture secondary to osteoporosis, (2) ruled out fracture of the pubic bone, (3) cirrhosis, (4) chronic renal failure, (5) hypotension, (6) GERD, (7) esophageal varices, (8) status post gastric bypass surgery for obesity
