[Personal experience in the use of magnetotherapy in diseases of the musculoskeletal system].

Therapeutic application of pulsatile electromagnetic field in disorders of motility is recently becoming more frequent. Despite this fact information about the effectiveness of this therapy in the literature are rare. The aim of this study was therefore the treatment of 576 patients who suffered from vertebral syndrome, gonarthritis and coxarthritis. For application of pulsatile electromagnetic field MTU 500H Therapy System was used. Pulsatile electromagnetic field had a frequency valve of 4.5 mT in all studied groups and magnetic induction valve 12.5-18.75 mT in the 1st group. In the 2nd group the intensity was 5.8-7.3 mT and in the 3rd group it was 7.6-11.4 mT. The time of inclination/declination in the 1st group was 20/60 ms, in the 2nd group 40/80 ms and in the 3rd group 40/90 ms. The electromagnetic field was applied during 10 days. In the 1st-3rd day during 20 minutes and in the 4th-10th day during 30 minutes. The therapy was repeated in every patient after 3 months with values of intensity higher by 50%. In the time of pulsatile electro-magnetotherapy the patients were without pharmacotherapy or other physiotherapy. The application of pulsatile electromagnetic field is a very effective therapy of vertebral syndrome, gonarthritis and coxarthritis. The results have shown that the therapy was more effective in patients suffering from gonarthrosis, than in patients with vertebral syndrome and least effective in patients with coxarthosis. Owing to regression of oedema and pain relieve the motility of patients improved. (Tab. 3, Ref. 19.)

[Ilizarov reconstructive surgery--a solution for complex problems of the musculoskeletal system].

The Ilizarov technique is an important modality of reconstructive surgery for limb deformities, such as malunion and nonunion of fractures, persistent osteomyelitis, and bone loss following complex limb injuries, as well as in limb-lengthening procedures. It has received wide recognition in the Western world over the past decade. In MEDLINE we found 537 articles published between 1971-1995 that describe the use of this technique. Of these, only 18 were published between 1971-1975, while 261 were published between 1991-1995. The present paper describes the developments and updates in this method, as a result of the large experience gained by the authors in a number of centers in Israel using this technique. The Ilizarov apparatus is a circular frame that allows accurate control, much more than any other external fixator, during correction of limb deformities and limb-lengthening. It is minimally invasive, and open techniques and use of internal hardware and bone grafts are not needed. Based on our experience, we suggest that this method requires careful preoperative planning and meticulous surgical technique. More important, cooperation between surgeon and patient throughout the lengthy treatment is a prerequisite to ensure complete success, even in the most complicated cases.

Reliability of measuring volume by different methods for tumors of the musculoskeletal system.

In the present study different methods for determining the volume of a tumor were evaluated. For 12 models, the real volume, the volume according to measurement of the surface area on MRI, an ellipsoid and a cylindrical approximation of the volume, as well as the maximum diameter, were determined. There appeared to be a good correlation between all calculated volumes and the real volume. The error (mean: 17%) and the standard deviation (SD: 14%) on this error were smallest if the volume was determined by means of determination of the surface area. The ellipsoid approximation resulted in a smaller error (mean: 0%) but a higher standard deviation (SD: 27%). The cylindrical approximation resulted in unacceptable deviations (mean: 51%; SD: 40%). Volume was significantly related to the maximal diameter to the power of 2.3. Volume calculated according to this power resulted in an error of 18%. Standard deviation in this case however was unacceptable (SD: 89%). Volume calculation based upon the determination of the surface area has given the best and most reliable results. Ellipsoid approximation was less reliable, but faster and cheaper. Cylindrical approximation was unacceptable. Size, expressed as maximal diameter of the tumor, was also unacceptable as a parameter for volume.

[Development of three-dimensional imaging of the musculoskeletal system and its diagnostic capability].

Since 1987 we have studied osseous surfaces reconstructed three-dimensionally (3-D) from CT images with the cooperation from Hitachi Medico Co., Ltd. From these studies we have developed the following method for various clinical use. The method of this 3-DCT system could treat rather noisy images scanned with low radiation exposure because of the high contrast ratio (CT number) between bones and soft tissues, in the CT images. In addition, the 3-D calculation treated only the extracted data instead of all the CT images data, and the high speed processor was used in our system. These were effective to reduce the processing time. Furthermore, the system provided a natural stereoscopic view using a mixture shading method. Subsequently, this 3-DCT system was applied to clinical cases to examine its diagnostic capability. These results indicate that the 3-DCT system is useful in evaluating pathological conditions of bones and joints.

[Interscapular-thoracic resection in the treatment of patients with tumors of the musculoskeletal system].

Data of 13 patients with tumors of the locomotor system subjected to +interscapular-thoracic resection (ITR) are presented. Main technical aspects of ITR are described. Complications took place in 6 patients, including marginal necrosis of the skin in 4 patients. As a whole the 5-year survival made up 49.9% +/- 13.8%. Data are presented on rehabilitation measures which allow to widen the functional possibilities of the extremity.

Does exercise cause arthritis? Long-term consequences of exercise on the musculoskeletal system.

Recreational exercise has achieved great popularity. Possible benefits to participants include increased longevity, decreased risk of cardiovascular disease, improved psychological well-being, and greater fitness. An important but yet unanswered concern is whether exercise or physical overuse conditions play a role in the pathogenesis of OA. In humans, anecdotal observations have suggested relationships between recreational activities and degenerative joint disease. The few controlled studies that exist, however, reported have indicated that exercise need not be deleterious to joints. Available data may be interpreted to suggest that reasonable recreational exercise--carried out within limits of comfort, putting joints through normal motions, and without underlying joint abnormality--need not inevitably lead to joint injury, even over many years. Finally, we are witnessing thoughtful re-evaluation of physical exercise as a therapeutic modality for arthritis patients. It is possible that certain patients may achieve psychological and clinical benefit from selected exercise programs.

[Study of the musculoskeletal system of the spine in humans after long-term space flights by the method of computerized tomography].

By computer tomography, mineral density of lumbar vertebrae and their segments as well as back muscle (++ilio-costal, extensor and ++inter-spinal) density and mass were measured in four Salyut-7 crewmembers before and after extended flights (of 5 and 7 months in duration). These findings are in good agreement with the results of prolonged bed rest studies in which trabecular bone of vertebral bodies was investigated: mineral density diminished only in some (approximately 10%) of the test subjects. At the same time mineral density loss was seen in the vertebral elements where muscles were attached. Also, muscle mass was reduced. It is emphasized that the level of changes was not correlated with flight time. Further investigations in this area are discussed.
