Abstract
Skeletal lesions caused by multiple myeloma often lead to pain, pathological fractures, spinal instability, and compression of the spinal cord and nerve roots. The choice of therapy options is made by an interdisciplinary basis with oncologists and radiotherapists on the basis of comorbidities, prognosis, localization, and number of lesions. Surgical management has asupportive role in pain relief, the prevention and treatment of pathological fractures, and the decompression of the spinal cord and nerve roots. An adequate preoperative workup is essential for planning surgical treatment, which includes magnetic resonance imaging of the spine. In the case of unstable spinal lesions, minimally invasive and open surgical procedures, as well as their combination, are available for stabilization and decompression. In impending and pathological fractures of the extremities, surgical procedures are superior to conservative therapy for pain relief, restoring stability, walking ability, and limb function. There are multiple options available, including osteosynthesis using bone cement and plates, intramedullary nails, and bone replacement with implants and tumor endoprostheses with good functional results. Permanent reconstruction of the lesions should be the goal of any surgical intervention. The indication for curative, wide resection of the tumor should be considered for solitary plasmocytomas of the bone. Adjuvant radiotherapy leads to significantly improved local tumor control and should be considered after resection and stabilization.
