Presentation And Management Of Bilateral Fracture Shaft Humerus In A Multiple Myeloma Patient: An Extremely Rare Case Report And Review Of Literature

Multiple myeloma (MM) is a malignancy of plasma cells and the second most common hematologic malignancy (13%); these cells accumulate in bone marrow and overproduce a monoclonal protein. The bone disease develops in 80–90% of patients with MM includes bone pain, pathologic fractures (40%), spinal cord compression (5%), and hypercalcemia. Pathological fractures can occur in extremities, but bilateral involvement is extremely rare. We report a case of 65-year-old male presented with a chief complaint of spontaneous bilateral humerus shaft fractures. On subsequent workup, MM was confirmed. The patient was managed with internal fixation bilaterally and showed favorable union at 1-year follow-up
