Compared with the recurrence rates published by other authors this is a very good result. The rate of recurrence for solitary bone cysts treated by curettage or segment resection was 23.5%. In 55 patients with fractures in the area of benign bone lesions complete healing was achieved, in 9 cases with conservative therapy. For 68 patients who died after stabilization, the average survival time was 11.6 months individual survival time depended on the kind of the tumour present. Of 74 patients, with malignant bone lesions 6 (8.1%), are still alive. Surgical treatment was performed in all but 1 case of malignant pathologic fractures. Most fractures appeared in adolescent patients up to the age of 19 and in adults between the 5th and the 7th decade, and 57.3% of the fractures were caused by a primary or secondary malignant tumour lesion. The favoured methods of surgical stabilization were endoprosthesis and reinforced osteosynthesis. The most frequent localizations of pathologic fractures were humerus and femur. Most fractures were caused by skeletal metastasis (61), solitary bone cysts (19), osteoporosis (17) and plasmocytoma (16). Conservative therapy was possible in 10 cases, while 133 fractures had to be treated surgically. Background/Aim: Pathological fractures are rare, suspicious and in some cases mentioned as the first sign of a malignant tumor. Between 19 we treated 131 patients with 143 pathologic fractures. In cases of progressive neoplastic disease stabilization is necessary to attenuate pain and to maintain mobility. Collapsed vertebra, not elsewhere classified. Various surgical procedures are available for fractures at different sites and depending on whether the operation is performed with curative or palliative intent. Osteoporosis with current pathological fracture M80- collapsed vertebra NOS (. In most cases it is combined with adjuvant therapy. In malignant pathologic fractures surgery is an essential part of the overall oncologic treatment design. In cases of benign bone lesions the aim of treatment is total osseus healing with complete restoration of function. Diagnosis of the basic disease is important for the subsequent therapy. A pathologic fracture is one that occurs without adequate trauma and is caused by a benign or malignant bone lesion. Compared with bone fractures caused by trauma, pathologic fractures due to diseased bone are rare events.
