Late diagnosis leads to complications, which in turn increase the percentage of disability. Therefore, the search for the most informative method with the least radiation load on the patient remains an urgent problem for radiologists. Cone beam computed tomography (CBCT) is a modern and  promising technique that has already found wide application in dentistry and otorhinolaryngology. Among the advantages of CBCT are: three-dimensional image; high spatial resolution; low radiation dose. Thanks to technical improvements in equipment and the introduction of new image processing protocols, it has become possible to expand the indications for conducting the researches, including the researches based on imaging of the upper and lower extremities. Based on the results of a CBCT study, we can evaluate: the shape and contour of the bone; solution of continuity of the bone and malposition of bone fragments; the structure of bone tissue and  the  pathological processes occurring in it (destruction, osteoporosis, osteosclerosis); joint congruence and changes in  articular surfaces surrounding soft tissues. Therefore, CBCT can be introduced into the diagnostic process of bones and joints diseases. The use of this technique will find wide application in traumatology and orthopedics (fractures, dislocations, post-traumatic deformities, aseptic necrosis, osteoarthritis), rheumatology (rheumatoid arthritis, polyarthropathy, juvenile arthritis, gout), surgery (osteomyelitis), oncology (benign and malignant bone tumors) both in the adult population and in pediatric practice. This paper presents a review of the literature, which examines the degree of development of the issue of using CBCT and describes study protocols and protocols for processing the obtained images in the diagnosis of musculoskeletal diseases.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"2 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139006818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Massive rotator cuff tears account for 10–40 % of all rotator cuff tears. Massive rotator cuff tears are considered to be tears with a diastasis of more than 5 cm or tears involving two or more tendons. With such injuries, the kinematics of the shoulder joint changes: proximal subluxation of the humeral head and arthropathy of the shoulder joint occur, which subsequently causes pseudoparalysis. The main clinical manifestations are pain and dysfunction of the shoulder joint. Patients may experience a loss of active range of motion in the shoulder joint while maintaining passive range of motion. There is currently no unified approach to the choosing the tactics for surgical treatment. The most common options include partial rotator cuff repair, subacromial balloon plasty, replacement of tendon defects with allografts and autografts, proximal shoulder joint capsule plasty, muscle-tendon transfers, and shoulder joint arthroplasty. However, according to the literature data, the frequency of re-ruptures after surgery ranges from 11 % to 94 %. Despite the large number of methods for the treatment of massive rotator cuff tears, there are no clear algorithms for managing patients and choosing one or another surgical tactics. In addition, there is a high percentage of unsatisfactory outcomes of treatment.

To study the restoration of cortical bone density in the area of osteoplasty using tissue-engineered construct in the experiment. Materials and methods. In an in vivo experiment on New Zeland White (NZW) rabbits, perforation defects of cortical bone were formed in the femoral diaphysis. Three study groups were set up: group 1 – without bone defect replacement; group 2 – with  bone defect replacement with deproteinized cancellous bone; group  3  – with bone defect replacement with tissue-engineered construct based on deproteinized cancellous bone with stromal vascular fraction of adipose tissue. Follow-up periods were 2, 4 and 6 weeks after the surgery. The X-ray density of cortical bone tissue was measured in Hounsfield units (HU). Fragments of deproteinized human cancellous bone were used alone and in combination with the stromal vascular fraction of NZW rabbit adipose tissue as a bone-replacing material for bone defect replacement. Results. Cortical plate density the in the area of the defect in the group 3 by the week 6 is on average 1.3 times lower than that of the intact cortical plate and corresponds to D1 according to Misch classification. Cortical plate density in the area of the defect on the side of medullary canal by the week 6 in the group 3 corresponds to D1 according to Misch classification and is equal to 1351.25 ± 221.18 HU (1052; 1805), which is 1.5  times higher than in group  2 (D2 according to Misch classification; p < 0.05).

To study the frequency and treatment options for dysfunction of the dynamic stabilization system of the lumbar spine. Materials and methods. We carried out a retrospective analysis of the treatment of 58  patients with degenerative pathology of the lumbar spine and instability of the spinal motion segments, who were treated at the neurosurgical unit of the Irkutsk Scientific Centre of Surgery and Traumatology in 2011–2020. The stability of spinal motion segment was assessed using X-ray imaging, magnetic resonance imaging and multi-layer spiral computed tomography of the lumbar spine. Revision surgery was performed in 7 out of 58 previously operated patients using the dynamic fixation system of spinal motion segments “Coflex” (Paradigm Spine LLC, Germany). Results. Revision surgery was performed in 7 out of 58 patients with dynamic fixation of the spinal motion segments with an interosseous implant due to an increase in pain syndrome. In 1 patient, the reason for repeated surgery was primary instability of the hardware caused by a fracture of the spinous process. In the delayed period, 4 patients had an X-ray picture with heterotopic ossification of the implant and instability of PDS. In two observations, a recurrence of intervertebral hernia was diagnosed at the level of the operated spinal motion segment. During revision surgery, a facetectomy was performed with stabilization by a peek cage, followed by pain management and clinical manifestation regression. Conclusion. The conducted study shows that a number of patients after discectomy and dynamic stabilization of the spine using “Coflex” system have inconsistency and  heterotypic ossification of  the implant and neoarthrosis. Implantation of a lumbar peek cage while maintaining the “Coflex” device makes it possible to form a rigid interbody fusion, which means it is sufficient and justified surgical technology for treating the failure of the dynamic stabilization system.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"30 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim. To establish the prevalence, risk factors and clinical significance of acute kidney injury after primary hip replacement performed in the clinic of the Irkutsk Scientific Centre of Surgery and Traumatology. Materials and methods. We carried out a retrospective analysis of the case histories of 109 patients who underwent primary total hip replacement under conditions of subarachnoid anesthesia in the clinic of the Irkutsk Scientific Centre of Surgery and Traumatology in 2021. Results. Postoperative changes in serum creatinine in 8 patients of the study group met the KDIGO (The Kidney Disease: Improving Global Outcomes) criteria for acute kidney injury. Initial indicators of renal excretory function in the subgroup with acute kidney injury were not different from those in the entire group. Statistically significant correlation was established between acute kidney injury and indicators of oxygen-carrying capacity of blood – initial and minimal postoperative hemoglobin concentration. Acute kidney injury in patients of the study group had a minimal effect on the clinical course of the early postoperative period. None of the patients required renal replacement therapy, re-transfer from the specialized unit to the intensive care unit or any specific treatment. The duration of postoperative stay of patients with acute kidney injury in the clinic did not increase. Conclusions. Acute kidney injury was detected in 7.3  % of patients who underwent primary total hip replacement. Risk factors for the development of postoperative acute kidney injury in  patients of the study group included relatively low initial and  minimal postoperative blood hemoglobin concentrations, which may indicate prerenal mechanism of acute kidney injury pathogenesis.

With age, the probability of having a rupture increases, reaching 51 % in people over  80  years of age. The main diagnostic tools are radiography and  magnetic resonance imaging of the shoulder joint combined with clinical examination.

An in-depth analysis of the scientific works of scientists and medical practitioners allows us to conclude that locked nail intramedullary osteosynthesis is  the optimal and the most effective method of treating closed diaphyseal fractures of the lower leg bones, which is caused by the high stability of osteosynthesis and minimal damage to soft tissues during surgery. The processes of microcirculation changes in the early postoperative period by various metal structures, including a locked intramedullary nail, still remain unexplored. In particular, there is insufficient data on the use of a locked intramedullary nail. The aim of the study. To identify the features of changes in microcirculation indices of injured lower leg bones during fixation of fragments with a locked intramedullary nail in the early postoperative period. Materials and methods. The microcirculation of the lower limb segment was studied in 25 patients using laser Doppler flowmetry. Data from 25 healthy volunteers were used as a comparison group. Results. It was found that in the early postoperative period, from day 1 to day 10, in patients with diaphyseal fractures of the lower leg bones operated with locked nail intramedullary osteosynthesis, there is a decrease in the cardiac range, an increase in the share of the shunt component of microcirculation compared to the nutritional share, as well as an increase in more than 1 ratio of the cardiac and respiratory range amplitude, which indicates an ischemia type of local circulatory disorder. Compensation of ischemia is done by anastomoses, since the bypass rate is increased. Conclusion. In case of surgical treatment with locked nail intramedullary osteosynthesis, in the early postoperative period, an ischemic type of compensated local circulatory disorder develops. The regeneration process takes place under conditions of reduced arterial microcirculation blood flow and stable venous outflow, as well as the inclusion of anastomoses to compensate for destroyed vessels, which is associated with nail damage to the internal blood flow of the bone endosteum and intraosseous nutrient artery during the surgery.","PeriodicalId":32463,"journal":{"name":"Acta Biomedica Scientifica","volume":"34 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138980195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
