[The malignant fibrous histiocytoma of bone (author's transl)].

The primary malignant fibrous histiocytoma of bone (Stout) is a rare and autonomous sarcoma of the bone which has to be separated from the osseous sarcoma and the osseous fibrosarcoma. The malignant histiocytoma is morphologically characterized by the storiform pattern of interlacing spindle cell bundles and functionally by the phagocytosis of lipids, glycogen, hemosiderin and hematoidin. Contrary to the osteosarcomas, the main age of osseous histiocytomas are the fifth and sixth decade. Location of predilection are the metaphyses of the long tubular bones. The X-rays show moth-eaten spongiolysis, endosteal erosion and perforation of the cortex. Early metastases in the lungs are frequent. The primary treatment is a surgical one. Case record of a typical malignant osseous histiocytoma from the proximal metaphysis of the left femur with metastases in the lung of a female child, aged 14 years.

[Experiences with arthroplasty for tumors and metastases of the proximal femur and humerus (author's transl)].

This report describes the results of 17 arthroplasties of the hip joint for tumors or metastases in the proximal part of the femur and 3 arthroplasties of the shoulder joint because of tumors in the proximal humerus. Based on case reports the paper discusses the indication in the case of malignant, potentially malignant and benign primary bone tumors and in the case of metastases. In addition principles for the construction of suitable hip and shoulder prostheses are cited, whereby the partial joint replacement continues to retain its justification beside total replacement. While the results of the hip arthroplasty proved satisfactory, the results of the corresponding operation on the shoulder are less satisfactory and urge to exercise more restraint in the operative indication.

[Treatment of malignant fractures of the femur with total hip-femur-knee joint alloplastics (author's transl)].

This is to report as an example of 2 such cases, the indications and operative procedures of total hip-femur-knee joint alloplastics for malignant fractures of the femur. This is an alternative to the exarticulation of the femur in the case of impossibility to fix the osteosynthesis material on the remaining femur. The higher radicality of this method in comparison to the common femur-saving way might lead to a wider usage.

[The value of intra-osseous angiography for primary, malignant bone tumours (author's transl)].

By means of intra-osseous angiography, it is possible to demonstrate abnormal vascularisation, the vascular pattern of osteolytic sarcomas differing markedly from that of osteoplastictumours. Important information can be obtained regarding the close relationship between tumour vessels and the parosteal soft tissue vessels. The close relationship between these provides ample explanation for the early occurrence of haematogenous metastases. The extent of the intramedullary tumour component of chondrosarcomas can also be demonstrated.

[Xeroradiography in the diagnosis of skeletal diseases (author's transl)].

The value of xeroradiography in the diagnosis of peripheral skeletal lesions is illustrated by some typical examples and compared with standard radiographic procedures. The advantages of xeroradiography depend on its convenient format, easy appreciation of structural changes and easy viewing. On the other hand, density gradations are flattened. Compared with a technically satisfactory film examination, there is no increase in diagnostic information. Xeroradiography can therefore only be regarded as complementary to conventional radiography for the diagnosis of skeletal conditions.

Solitary bony metastasis as the first sign of malignant gastric tumor or of its recurrence.

Symptomatic solitary bony metastasis as the First sign of asymptomatic gastric carcinoma is very infrequent. Only 8 cases reported by 7 authors have been found in the literature. Furthermore, solitary bony metastasis as the sole sign of recurrence after hopefully curative resections are so rare that none has been previously reported in the literature. Three additional instances of solitary and histologically proven osseous metastasis of malignant gastric neoplasms have been observed and treated at Memorial Hospital during the years 1949 through 1969, and are herewith reported.

Surgical treatment of myelomatosis--a review of 18 cases.

The authors review 18 patients with multiple myeloma who had bone destruction of a kind that indicated surgical therapy. Eight patients had paralegic myelopathy and one had compression of the cauda equina. Four of them displayed partial to complete regression. One patient lived for 77 months after the operation, most of the time in excellent condition. The operative technique is discussed, with laminectomy, exeresis, filling of bone with cement and, in some instances, mechanical support from metal plates. Early diagnosis and operation is imperative, postoperative irradiation obligatory in severe cases. Radiation alone may be the method of choice in early stages. The other 9 patients were operated upon for bone destruction in the limbs. A Moore operation on the destroyed hip was performed in one patient, who lived in excellent condition for about four years. Active surgical therapy combined with radiation and cytostatics seems to be of value in many patients with multiple myeloma.

Angiographic features of fibromas and fibrosarcomas.

Angiography was done in 38 cases of pathologically-confirmed fibrous-tissue tumor. All benign fibromatous tumors and one case of desmoid fibroma were angiographically normal. A great spectrum of angioarchitecture exists in fibrosarcomas, whether they are of bone or soft-tissue origin. Heterogeneous vascularity was seen in 55% of these cases, and was related to the cell composition of the tumor. There exists a close relationship between the number of vessels in a tumor and its degree of clinical and histopathological malignancy. The most vascular part of a tumor is the least differentiated and should be used for biopsies. Angiography can be used for the grading of fibrosarcomas, and probably for assessing clinical prognosis.

Osteogenic sarcoma after the age of 50: a radiographic evaluation.

Twenty-four cases of primary osteosarcoma in individuals over the age of 50 are described. This represents 6% of all osteosarcomas and 80% of osteosarcomas occurring over the age of 50 at this institution. Radiographically, features were similar to osteosarcoma in younger individuals. Females were more frequently affected than males (2.4:1). The radiographic features are discussed in detail, and the differential diagnosis outlined.

[Therapy of bone metastases of the lower extremity with the KMFTR modular tumor endoprosthesis system].

During the years 1975 through 1989, 189 patients have been operated because of metastases within bones of the lower extremity. Thereof, 34 patients received an endoprosthesis of the KMFTR (Kotz Modular Femur-Tibia reconstruction system) type. In detail, the following reconstruction elements had been used: proximal femur (n = 20), distal femur (n = 7), complete femur (n = 2), proximal tibia (n = 5). At the time of follow-up examination 30 patients had died. Mean survival time after resection of metastases was 18.6 months (range 8-44 months). According to histologic judgement, in 23 cases wide or marginal resections had been performed whereas 11 patients had been operated intralesionally. In no case local recurrence as relevant to therapy was observed. At the same time-point, survival periods after detection of secondary manifestations of the malignant diseases within the remaining 4 patients were 29, 61, 73 and 125 months, respectively. The following complications were observed: luxation of the prosthesis (n = 6), transient paresis of the peroneus (n = 3), deep vein thrombosis (n = 2), pulmonary infarction (n = 1), wound healing disturbances (n = 2) and hematoma (n = 3).

[Complications caused by artificial hinge knee joint].

Artificial hinge knee joint was used in 25 patients with bone tumors around the knee joint. 23 patients were followed on the average for 3 years and 3 months. Complication was noted in 10 patients including infection in 7 (5 short-term, 2 long-term), broken joint in 1 patient and loosening in 2. The causes for complication and counter-measures were discussed.

Malignant fibrous histiocytoma with skeletal involvement.

Malignant fibrous histiocytoma of soft part is rather common but malignant fibrous histiocytoma of the bone is rarely encountered clinically. Authors present five cases of malignant fibrous histiocytoma with skeletal involvement and discuss their clinical course, x-ray findings and histological features. This tumor has marked tendency for local recurrence and metastasis. Other bone tumors such as giant cell tumor, aneurysmal bone cyst, non ossifying fibroma, osteosarcoma, fibrosarcoma of bone and metastatic cancer can be excluded by several characteristic findings observed in x-rays as well as histopathological features. All information on the patient should be carefully analysed, because it is difficult to decide whether bone involvement is primary or secondary. Four out of five cases definitely originated within the bone.
