STUDY OF DEFECTS OF LONGITUDINAL WELDED PIPE

A study of the defects of the longitudinal weld seam revealed by X-ray inspection was carried out. These defects were not detected by magnetic inspection. Erroneous identification of defects during X-ray inspection. Compliance of base metal and weld seam with regulatory documents.Работа выполнена в рамках государственного задания МИНОБРНАУКИ России (тема «Диагностика», № АААА-А18-118020690196-3)

Problems of semiotics of diseases of the Achilles tendon in clinical and educational aspects

Achilles tendon disorders are represented by a big group of heterogenous in etiology and pathogenesis conditions, that are quite frequent in patients of various age groups. The diversity of this group of orthopedic disorders and the insufficient information provided on this topic in specialized literature leads to confusion in terminology, which, in turn, leads to misunderstanding the essence of patient’s problem and to mistakes in treatment of such patients.We carried out a content-analysis of contemporary Russian and foreign literature to summarize the existing knowledge and to create the universal nomenclature of the studied pathological conditions for further correct understanding of the problem and creation of classification of disorders and injuries of Achilles tendon

IMPINGEMENT-SYNDROME OF PERONEUS BREVIS TENDON AFTER CALCANEAL FRACTURES (MORPHOLOGICAL ASPECTS)

Background. One of the main causes of pain in patients with consequences of calcaneal fractures is the lateral impingement syndrome. This term means lateral displacement of outer calcaneal wall at the moment of fracture, narrowing of anatomical space under the lateral malleolus and compression of soft tissues in this region, including tendons of short and long peroneal muscles. This leads to chronic traumatization of tendons, alteration of their normal tracking and development of tendinitis and tenosynovitis. At this moment there are no articles in foreign or Russian literature describing how prolonged traumatization influences the internal structure of the tendons. The purpose of this study was to evaluate the morphological changes in structure of peroneus brevis tendon after different duration of compression between outer wall of calcaneus and the tip of the lateral malleolus in patients with calcaneal malunion.Materials and methods. Fifteen patients with calcaneal malunion and lateral impingement syndrome were treated operatively between 2016 and 2017. To confirm the lateral impingement syndrome, the authors performed clinical examination and AP x-rays of ankle joint. Two peroneus brevis tendon specimens were obtained intraoperatively in each of 15 patients: one specimen from compressed and one from non-compressed area. Obtained specimens were histologically examined according to standard protocol.Results. Microscopically all specimens showed separation of collagen bundles with loose connective tissue degeneration, increase of vascularization and inflammation. The degree of these changes differed according to the compression duration. This allowed us to analyze the dynamics of these changes.Conclusion. The morphological changes in structure of peroneus brevis tendon during the compression between outer wall of calcaneus and the tip of the lateral malleolus correspond with dynamics of common pathologic reactions. Early stages showed signs of mechanical damage of bundles and inflammation. In prolonged impingement the intensity of inflammation decreases, but the connective tissue degeneration of the tendon continues with lipoid infiltration

OUR APPROACH TO TREATMENT OF NEGLECTED ACHILLES TENDON RUPTURES. IS THERE A SIMPLE SOLUTION?

Introduction. Subcutaneous rupture of achilles tendon is a frequent trauma and most patients with such pathology are men of working age. Even though it is not difficult to diagnose such ruptures, especially those that need surgical treatment, there are numerous cases when patients come to a surgeon with a big delay. In such cases, the rupture becomes «chronic» or «neglected» and can be no longer treated as an acute rupture. There are many techniques of operative treatment of chronic achilles tendon ruptures, but still there is no consensus on which technique is to be considered the most simple, effective and safe.The aim of this study is to evaluate the effectiveness of using peroneus brevis tendon as a graft for treatment of achilles tendon defects type 3 in Kuwada classification. Will this technique bring good and excellent results that are comparable with end-to-end suture after acute achilles tendon ruptures?Materials and methods. The present study includes 13 patients in which peroneus brevis was used for treatment of neglected achilles tendon rupture (group I) and 18 patients after end-to-end suture after acute achilles tendon rupture (group II). Group I consisted of patients with neglected rupture of achilles tendon that was not previously treated due to various reasons and with a significant defect.Results. Mean surgery duration in group I was 91.9±6.6 (Me — 100) min, in group II — 43.2±2.2 (Me — 45) (p = 0.0001). damaged limb was evaluated using achilles Tendon Total Rupture Score, mean post-op follow up was around 1 year. The results were: group I — 86.6±2.28 (Me — 87), group II — 93.4±1.01 (Me — 94) (p = 0.04). This means, that despite quite high scores in group I, they are still statistically worse than scores after suture of acute rupture in group II. There was no difference in post-operative complication rate between the groups (p>0.05). The most common complication for both groups was range of motion restriction in ankle joint. None of the patients had ankle joint instability after surgery.Conclusion. Management of neglected ruptures of achilles tendon type 3 (in Kuwada classification) with peroneus brevis autologous graft is an effective and safe technique, that achieves good and excellent results in treatment of this group of patients, in absolute numbers is comparable to functional outcomes after end-to-end suture of acute achilles tendon ruptures, but statistically demonstrates significantly worse results

Cardiovascular disease and non-communicable disease behavioral risk factor screening in Rostov-na-Donu citizens

A cardiovascular disease (CVD) screening study of 1350 Rostov-na-Donu citizens was performed. According to calculated clinical sensitivity and specificity, perspectives of «Cardiovisor - Obs « device use, as primary indicator of heart health and regulatory mechanisms status in screening studies, were determined. Among Rostov-na-Donu citizens, leading behavioral risk factors for non-communicable disease included smoking, low physical activity, and unhealthy diet, resulting in overweight and obesity. There is a need for special preventive program focused on suboptimal ecology region inhabitants
