Radiometry in a comprehensive assessment of the effectiveness of extracorporeal shock wave therapy of calcifying tendinobursopathy of the shoulder
Introduction. Uncomfortable working conditions and excessive professional loads on the shoulder joints cause a high prevalence of degenerative-dystrophic changes in the periarticular tissues. Calcifying tendinitis and bursitis occupy a special place, characterized by multifocal accumulation of calcium phosphate crystals in tendons, mucous bags and muscles. The study is devoted to solving the problem of optimizing the X-ray diagnostics of the evolution of calcifying tendinobursopathy of the shoulder (CTS) in the dynamic assessment of the effectiveness of extracorporeal shock wave therapy. The aims of the study to optimize the X–ray diagnosis of calcifying tendinobursopathy of the shoulder in people working under the influence of adverse production factors. Materials and methods. The authors conducted a comparative retrospective analysis of the results of a comprehensive dynamic clinical and X-ray examination of 155 able-bodied men aged 35-57 years with an average work experience of 14.5±2.7 years (miners, loaders, bricklayers) examined for pain syndrome and dysfunction in the shoulder joint. The main group (65 people) are patients with CTS clinic, the presence of calcifications in the periaricular tissues of the rotator cuff and in the biceps muscle of the shoulder, evaluated in dynamics after shock wave therapy (SWT) of the shoulder in the phases of rest, resorption and recovery. The comparison group (90 people) consisted of patients with the absence of instrumentally detectable signs of multifocal accumulation of calcium phosphate crystals in the periarticular tissues of the shoulder. The study included patients whose routine conservative treatment proved ineffective. The following criteria for the effectiveness of therapy were identified: pain at rest, measured using a visual analog scale (VAS); dimensions (calcification area (in mm2)); optical density and calcification density gradient. Specialists evaluated the data at the initial stage of the study before the use of therapy, immediately after treatment and 12 months after the final SWT session. Results. In patients of the main group with the presence of CTS, the main manifestations of shoulder-scapular periarthritis (SSP) both in the main group and in the comparison group were moderately pronounced, however, the frequency of detection of the main SSP syndromes, primarily rotator cuff lesion, as well as background pathology (arthrosis of the shoulder joint) and acromioclavicular joint) were significantly higher in the main group. The effectiveness of SWT was demonstrated by regression of pain syndrome and positive dynamics of density characteristics of periarticular tissues of shoulder joints in areas of interest (in anatomotopographic projections of localization of tendons, mucous bags and muscles). In all patients of the main group, the decalcification process was characterized by both a visually perceptible pattern of disintegration and a decrease in its area, and a decrease in optical density immediately after the end of treatment. In 36.9% of patients, 12 months after the start of SWT, the X-ray and X-ray densitometric picture confirmed the prolongation of the decalcification process up to complete lysis of foci and calcification sites. Conclusions. In a comprehensive assessment of the effectiveness of CTS therapy, along with traditional X-ray diagnostics, special methodological techniques of radiometry (X-ray diffraction and X-ray densitometry in areas of interest) can be used, allowing for more accurate and more objective reflection of the direction of the dynamics of changes. The use of X-ray calcifications in the arsenal of methodological techniques, such as area, optical density and optical density gradient, can significantly improve the quality of diagnosis and avoid the use of computed tomography and an increase in radiation exposure to the patient. High-energy extracorporeal shockwave therapy is largely able to solve the problem of treating resistant forms of calcifying tendinobursopathy of the shoulder.
