Prior to the fall he had no history of symptoms. What is the best next step?Select the Correct AnswerBone scanChest RadiographNo further testingAssessment of calcium and vitamin D levelsSkin biopsy to check for collagen abnormalitiesCorrect Answer: No further testing Explanation: This patient sustained a pathological humerus fracture. The fracture occurred through a lesion that is well circumscribed and latent in nature. The radiographic appearance is diagnostic for a unicameral bone cyst of the humerus. No further testing is needed for diagnosis. A bone scan would be indicated if there were concern regarding other bone lesions that could aid in diagnosis. A metastatic bone lesion may be found on a chest radiograph. Other than the pathological fracture, findings such as osteopenia, deformities, and/or physeal abnormalities occur with generalized metabolic bone issues. No findings are classic for osteogenesis imperfecta. Therefore, no further testing of blood, skin, or genetics will be helpful in this scenario.
