[Staging of hemophilic osteoarthropathy using the Pettersson score. A study of 40 children and adolescents].

The degree of haemophilic osteoarthropathy was assessed by the Pettersson-score in 219 knees, elbows and ankles of 40 children and adolescents suffering from haemophilia. 55.3% of the joints were unaffected and only 8 joints showed score values greater than 8. Enlargement of epiphyses (36.1%) and irregular subchondral surface (32.9%) were the most frequent observations, while osteoporosis (5.4%) was only rarely observed. Haemophilic osteoarthropathy was most severe in the ankles, while the knees were only moderately affected. Among 11 patients 493 bleedings into 61 joints were observed during a four-year period. If the bleedings recurred, more than 3 bleedings per year always resulted in haemophilic osteoarthropathy.

[Pathology of spinal tumors].

The Bone Tumor Registry of Westphalia contains data on 7,400 tumors and tumor-like lesions of bone, 135 primary spinal tumors, 187 metastases, 98 plasmacytomas, 4 extranodal manifestations of Hodgkin and non-Hodgkin lymphomas of the vertebral column. The most frequent type of primary tumor is the chordoma (35 cases), followed by osteoblastoma (16 cases), eosinophil granuloma (16), and hemangioma (12 cases). Most of the metastases derive from carcinoma of the breast, bronchial carcinoma, or prostate carcinoma. The present review concentrates on differential diagnosis by means of histological examination, with particular reference to immunohistological methods. In addition, the necessity for complementary assessment of the X-ray findings and histology is emphasized. In particular, the current status of knowledge on the prognosis of primary spinal tumors is presented. In our experience, the preparation of nondecalcified plastic sections has proved especially valuable for diagnostic procedures using punch biopsy specimens.

[Diffuse idiopathic skeletal hyperostosis as a cause of dysphagia].

Radiographic, clinical and pathologic abnormalities of diffuse idiopathic skeletal hyperostosis (DISH) are presented. Definite criteria must be fulfilled to differentiate DISH from other diseases of the spine, especially intervertebral osteochondrosis and ankylosing spondylitis. A case of massive DISH in the cervical spine causing dysphagia is described.

[Initial experiences with gadolinium DTPA in magnetic resonance tomography of bone and soft tissue tumors].

MR was performed in 41 patients suffering from benign and malignant bone and soft-tissue tumor before and after intravenous injection of the paramagnetic agent gadolinium-DTPA (Gd-DTPA). Using T1-weighted parameters, the contrast of tumor tissue versus muscle could be increased by Gd-DTPA. Thus, extraosseous extension as well as infiltration of the spinal canal was depicted to better advantage. Inhomogeneities were visualized with higher frequency and improved contrast. In several instances, there was no differentiation between tumor and adjacent edema without application of Gd-DTPA. T2-weighted images without Gd-DTPA exhibited higher contrast as compared to T1-weighted images after Gd-DTPA. The contrast to tumor tissue versus fat and bone marrow respectively was reduced after applying Gd-DTPA. Thus, for the evaluation of bone marrow infiltration, T1-weighted images without Gd-DTPA proved to be indispensable.

[X-ray diagnosis of foot deformities].

In order to analyze foot deformities, the foot is divided into three compartments. Their normal and pathological positions are defined by the alignment of the bones' axes. The various foot deformities can be put down to a malalignment of the particular compartments. X-ray analysis of the malalignment allows a diagnosis to be made. The most important congenital and acquired foot deformities are discussed.

[Giant cell tumor of bone].

This retrospective study analyses 67 patients with 69 giant cell tumors of bone staged according to the Surgical Staging System of benign and malignant lesions of Enneking (1980, 1986). A significant correlation between Stage 2 and Stage 3 benign lesions in respect to local recurrence as well as between the therapeutic procedures and recurrence was found. Intralesional excision with temporary acrylic cement implantation showed to be the preferable initial treatment of these tumors. Special attention to surgical staging, surgical techniques and a supervised rehabilitation program minimize the incidence of recurrence and at the same time giving am maximum of joint function.

[Giant cell tumor of bone. An analysis of 69 cases].

1. The tumor stage of the giant cell tumor is an indicator for the prognosis and the need for adjuvant therapy. 2. Intralesional excisions without an adjuvant result in high rates of recurrence. 3. Polymethyl methyl acrylate (PMMA) largely prevents recurrences, provides stability and makes early functional treatment possible. 4. Broad excisions should only be performed in bone which is dispensable. 5. Recurrences frequently manifest themselves by pain. They can be removed intralesionally, as in primary therapy.

Reproducibility of the pettersson scoring system. An interobserver study.

By means of the Pettersson scoring system, the degree of severity of haemophilic arthropathy in 128 knee, elbow and ankle joints was estimated by 5 radiologists. Their scores varied on average by approximately 3 points. Minimal and maximal joint involvement were scored consistently; exclusion of haemophilic arthropathy was possible with the highest degree of certainty. With regard to changes of a moderate degree agreement was seldom reached. With precisely defined characteristics, a high degree of consistency between observers was evident. Interobserver variation in the scoring was more marked in the ankle joint than in the other joints. Scoring was more consistent with the more experienced observers.
