New dyes for guest-host mode

New guest-host dyes of red and purple colour suitable for fabrication of ultrathin film polarizer from polymerizable liquid crystals are developed. When the absorption spectrum of dye matches the photopic curve, samples with total film thickness below 50 μm show good visual contrast

Реконструкция повреждений ротаторно-бицепитального комплекса при оперативном лечении переломов проксимального отдела плеча

The aim of the work was to improve the results of surgical treatment of patients having fractures of the proximal shoulder with the use of the approaches, including the reposition of bone fragments with adequate osteosynthesis and prevention of impingement syndrome, the reconstruction of all damaged structures of the rotator-bicipitale complex. A score assessment of the treatment results of 512 patients aged from 18 to 87 years old was performed, operated from 2004 to 2018 for the treatment of which the tactical approaches and the methods of surgical treatment developed by the authors aimed at restoring the rotator and bicipital elements were used. The use of the developed tactical approaches and methods made it possible to achieve a favorable outcome of treatment in 503 (98.2 %) patients. Thus, the reconstruction of injuries of the rotatory-bicipital complex is a promising way to improve the results of treatment in patients with fractures of the proximal shoulder.Улучшение результатов оперативного лечения пациентов с переломами проксимального отдела плеча, пролеченных с применением подходов, включающих в себя репозицию костных отломков с адекватным остеосинтезом и профилактикой импинджмент синдрома, реконструкцию всех повреждённых структур ротаторно-бицепитального комплекса являлось целью работы. Произведена балльная оценка результатов лечения 512 пациентов в возрасте от 18 до 87 лет, оперированных за период с 2004 по 2018 г., при лечении которых использовались разработанные авторами тактические подходы и способы оперативного лечения, направленные на восстановление ротаторного и бицепитального элемента. Применение разработанных тактических подходов и способов позволило достичь благоприятного исхода лечения у 503 (98,2 %) пациентов. Таким образом, реконструкция повреждений ротаторнобицепитального комплекса является перспективным путем улучшения результатов лечения у пациентов с переломами проксимального отдела плеча

RECONSTRUCTION OF DAMAGES TO THE ROTATOR AND BICIPITAL ELEMENTS OF THE ROTATOR-BICIPITAL COMPLEX IN THE TREATMENT OF THE PROXIMAL SHOULDER

Background. The topicality of the topic is determined by the frequency of injuries of the proximal shoulder, which account for up to 80% of all bone injuries of the upper limb girdle, while approaches to their reconstruction are unresolved. When analyzing adverse treatment outcomes retrospectively, insufficiently accurate reposition of bone fragments, underestimation of soft tissue lesions, and osteosynthesis without prophylaxis of impingement are often noted, but the measures for their prevention are not straightforward. Objective: to improve the results of surgical treatment of patients with proximal shoulder fractures. Material and methods. The material of the study is the evaluation of the results of treatment of 512 patients aged from 18 to 87 years old, operated from 2004 to 2018 using the tactical approaches and methods developed by the authors to restore the rotator and bicipital elements of the rotator-bicipital complex. Research results. The use of the developed tactical approaches and methods enabled to achieve a favorable outcome of treatment in 503 (98.2%) patients. Conclusions. Reconstruction of injuries of the rotator-bicipital complex is a promising way to improve the results of treatment in patients with fractures of the proximal shoulder

DAMAGE TO THE ROTATOR-BICIPITAL COMPLEX WITH INSTABILITY OF THE TENDON OF THE LONG BICEPS HEAD

Background. Pain in the shoulder joint is a topical problem of modern traumatology and orthopedics. One of the most common causes of pain arising in the anterior shoulder is instability of the tendon of the long biceps head (SDHB). Purpose. To analyze the frequency of concomitant damage to the rotator and bicipital elements of the rotatorbicipital complex with instability of the tendon of the long biceps head. Material and methods. The article presents the results of a prospective and retrospective analysis of 66 patients over the period from 2004 to 2018. Of these, 51% were men (77.3%), 15 - women (22.7%). The age varied from 19 to 77 years old, the average age was 47.3 ± 15.9 years. The patients were examined according to the algorithm developed by the authors, which is used in everyday practice. Results and conclusions. The figures of descriptive statistics and the statistical analysis carried out using the association coefficient of D. Yul indicate a direct, strong, statistically significant relationship between the damage to the rotator apparatus and the tendon of the long biceps head. The developed algorithm for the diagnosis of traumatic injuries of RBC is simple and highly effective in making a diagnosis in patients with instability of the tendon of the long biceps head
