Approach to the treatment of osteomyelitis and fractures with critical bone loss using biocomposites containing nanoparticulate polymeric systems for intracellular delivery of BMP-encoding plasmids, tenoxicam, and vancomycin
BACKGROUND: Osteomyelitis remains a pressing problem due to its high recurrence rate and risk of serious complications. The situation is exacerbated by increasing antibiotic resistance, which reduces the effectiveness of conventional antibacterial therapy. In this context, the development of novel therapeutic strategies for osteomyelitis, especially in cases accompanied by critical bone loss, is of particular importance. AIM: The work aimed to test an approach to the treatment of purulent-septic inflammation complicated by bone tissue loss using biocomposite bone implants impregnated with a gel exhibiting multifunctional pharmacological activity, providing local antibacterial, anti-inflammatory, and osteogenic effects. The efficacy of the approach was evaluated in a rat model of experimental osteomyelitis. METHODS: The research methods included the development of polysaccharide gels with mechanical and rheological properties similar to those of soft tissues (G’ = 176–271 kPa, G’’ = 3.7–4.2 kPa), containing 250 mg/g of dry polymer of amikacin and vancomycin, 0.28 mg/mL of tenoxicam gel, and 12.83 ng/mL of a plasmid encoding bone morphogenetic protein (BMP), thereby ensuring the implants exert local antibacterial and targeted anti-inflammatory effects in combination with stimulation of bone tissue growth. Two types of nanoparticulate carriers of different diameters were introduced into the gel: hyaluronic gel nanoparticles with a bimodal size distribution (d = 100 and 3000 nm) for intracellular delivery of tenoxicam into phagocytic immunocompetent cells, and nanocapsules coated with a transfection agent (d = 50–100 nm) for transmembrane transport of the plasmid into non-phagocytic cells, whose ribosomes synthesize BMP-2, initiating differentiation via the osteogenic pathway. Antibiotics are released from the carrier only in response to bacterial attack on the implant via bacterial enzymes, ensuring a local concentration 200 times higher than the bactericidal threshold. Cytotoxicity, calculated per dry gel, was 1800 µg/mL. The minimum inhibitory concentration against Staphylococcus aureus 209P was 25 µg/mL, and the bactericidal concentration was 100 µg/mL. RESULTS: Biocomposites impregnated with a drug-containing gel were found to effectively inhibit local bacterial infection, reduce the overall level of local aseptic inflammation, and promote bone regeneration in osteomyelitis. CONCLUSION: The therapeutic approach to treating purulent-septic inflammation complicated by bone tissue loss using implants with multifunctional pharmacological activity should be regarded as promising.

Comparative analysis of hand function after surgical repair of finger flexor tendons
BACKGROUND: Surgical treatment of flexor tendon injuries is associated with a high rate of poor outcomes and disability. Improving treatment results may be achieved by searching for new suture materials. Numerous reports in the scientific data describe the potential use of nickel-titanium–based materials in surgery; however, no references to the use of nickel-titanium wire in tendon surgical reconstruction have been reported. AIM: To conduct a comparative study of long-term outcomes in patients with flexor tendon injuries of the triphalangeal fingers in the osteofibrous canal zone, using a superelastic nickel-titanium wire and a polypropylene thread. METHODS: An interventional, single-center, prospective, controlled, non-randomized clinical study included 110 patients with injuries of the flexor digitorum profundus tendons in the osteofibrous canal zone. Patients were divided into two groups: the main group (n = 65), where a superelastic nickel-titanium wire was used, and the control group (n = 45), where polypropylene was applied. Surgical repair was performed using the M-Tang technique with a six-strand suture in both groups. Follow-up lasted 12 months, with control points at days 7–10, weeks 3 and 6, and months 3, 6, and 12. The primary endpoint was functional recovery of the finger assessed with the FingerSurg scale by measuring active joint motion and comparing it with the uninjured finger. Additionally, grip strength, pinch strength, and DASH questionnaire scores were recorded. RESULTS: Use of the superelastic nickel-titanium wire in tendon suturing of the flexor digitorum profundus demonstrated a higher rate of excellent results (78.5%) and a significantly lower rate of poor outcomes (1.5%) compared with the control group (p = 0.042). Grip and pinch strength recovery was also superior, especially in patients with incised wounds and early surgical intervention. No differences in quality of life as measured by the DASH score were found between the groups at 12 months. CONCLUSION: The results of this clinical study of hand function after surgical repair of flexor tendons at the level of the osteofibrous canal confirmed the advantages of the proposed tendon suture technique by reducing complication rates and improving postoperative outcomes.
The possibility of using infrared thermography in assessing the condition of the lower limbs
BACKGROUND: Medical infrared thermography (MIT) is a method of recording thermal radiation from the surface of the human body, which allows to identify pathological conditions of the body at the preclinical stage, as well as to monitor the treatment and rehabilitation process over time. The advantages of this method include non-contact examination, non-invasiveness, harmlessness, lack of need for highly specialized personnel and expensive consumables. AIM: To assess the condition of the lower extremities using medical infrared thermography. MATERIALS AND METHODS: The present study refers to experimental, blinded, single-stage, selective, uncontrolled, single-center. The study included respondents aged 18–21 years with no history of somatic diseases of the lower extremities. During the study, thermographic images of the anterior and posterior surfaces of both lower extremities were performed, after which points were placed on each of them indicating the temperature of the specified areas. These points were selected according to the anatomical location of the vessels of the lower extremities. The main outcome is the average values of the percentage change in temperature; an additional one is the identification of the relationship between the percentage change in temperature and the volume of subcutaneous fat. The study duration is 2,5 months. The chi-square criterion was used to calculate the statistical significance of the study. RESULTS: During this study, it was revealed that the physiological phenomenon of a decrease in temperature in the lower extremities from the proximal to the distal sections can be applied in practice (p <0.001). The graphs constructed in the course of the work proved that the percentage change in temperature does not depend on the state of subcutaneous fat, which differs from the temperature of anatomical points, the values of which completely depend on the volume of the fat layer in humans. CONCLUSIONS: this study is the first step towards using average statistical data on the percentage change in temperature between anatomical points on the lower extremities in practice. Due to measurements, calculations and plotting, it has been proven that this method of thermographic examination is universal for people with different complexions and body mass index, which greatly simplifies its use in diagnostics by doctors of different specialties.
Multislice computed tomography with intravenous bolus contrast enhancement in the assessment of pulmonary arteries
BACKGROUND: Patients with COVID-19-associated pneumonia are at high risk of thrombotic complications, including in the postoperative period. Multislice computed tomography with intravenous bolus contrast enhancement improves the visualization of the pulmonary vasculature, enabling accurate identification of thrombi, degree of stenosis, and occlusion. This noninvasive and highly informative method allows for the prompt and precise diagnosis of life-threatening conditions such as pulmonary embolism, as well as the confirmation or exclusion of other vascular conditions. Multislice computed tomography with intravenous bolus contrast enhancement is a modern, rapid, and accurate diagnostic tool for detecting and evaluating pathological changes in the pulmonary arteries, which is critical for an optimal treatment planning and improving patient outcomes. AIM: The work aimed to evaluate the use of multislice computed tomography with intravenous bolus contrast enhancement in diagnosing pulmonary embolism in patients with COVID-19-associated pneumonia; to analyze the correlation between the incidence of pulmonary embolism and the severity and stage of SARS-CoV-2-induced pneumonia. METHODS: A retrospective study was conducted including 184 patients with COVID-19-associated pneumonia and suspected pulmonary embolism based on laboratory findings. All patients underwent contrast-enhanced multislice computed tomography angiography to assess pulmonary arterial branches and parenchymal lung changes. RESULTS: Based on the study findings, pulmonary embolism was diagnosed in one out of five patients, most frequently presenting with mild perfusion deficits and minimal pulmonary parenchymal involvement due to pneumonia. CONCLUSION: The study demonstrated the high diagnostic value of multislice computed tomography angiography in detecting pulmonary embolism in patients.
Experimental study of the fixation properties of various biomechanical options for plate osteosynthesis of comminuted impaction fractures of the tibial plateau
BACKGROUND: Various biomechanical options are used in surgical practice to fix osteochondral fragments, including support on a bone graft reinforced with subchondral wires, osteosynthesis with forked fixators, and specialized plates with screws placed directly under the articular surface fragments. In the work, a method of subchondral tensioned reinforcement was utilized. AIM: The work aimed to evaluate and compare the fixation properties of different biomechanical osteosynthesis options for comminuted intra-articular fractures using porcine tibial bone models. METHODS: An indented, single-center, non-blinded experimental study included two types of models that shared identical fracture configurations, bone defect parameters, and non-tensioned wire reinforcement: A, with the bone defect filled with a graft, and B, without a bone graft. The results of osteosynthesis in models A and B were examined: 1) plate osteosynthesis with support of the articular surface on a bone autograft, option A-I; 2) plate osteosynthesis with support of the articular surface on the plate’s fixing elements and the bone graft, option A-II; 3) plate osteosynthesis with fixation of articular surface fragments using U-shaped tensioned wires, option B-III; 4) osteosynthesis with fixation of the articular surface using tensioned subchondral wires in a modular plate-based fixation device, option B-IV. Testing was performed under static indentation on models from the proximal metaphyseal-epiphyseal region of porcine tibia. RESULTS: The best fixation properties were observed in the tensioned subchondral reinforcement options B-III and B-IV compared with non-tensioned wire reinforcement (model A). When comparing the four biomechanical options, the best strength characteristics were observed in the variants with tensioned subchondral reinforcement: B-III and B-IV. In the study of Option A-II, the resistance of the biomechanical system to vertical load was lower than in Options B-III and B-IV. The worst variants were observed in option A-I. CONCLUSION: The most effective fixation was achieved with tensioned subchondral reinforcement using U-shaped wires (B-III) and a modular plate-based fixation device (B-IV) without the use of an additional bone graft.
Comorbidity in the context of medical rehabilitation in patients after total arthroplasty of major lower limb joints
BACKGROUND: The effectiveness of restoring motor activity after total arthroplasty of major lower limb joints (TAMLJ) is determined by baseline physical activity, demographic characteristics, body mass index, comorbidities, and the presence of chronic pain. AIM: To assess the impact of comorbid conditions on the effectiveness of medical rehabilitation in patients after TAMLJ and to substantiate optimal approaches to restorative treatment. METHODS: A prospective cohort study involving 120 patients aged 55–70 years was conducted. Four groups were formed: control (without comorbidity), with hypertension (HT), diabetes mellitus (DM), and overweight (OW). The rehabilitation program included individualized therapeutic exercise, mechanotherapy, physiotherapy, and locomotor correction using the HP Cosmos robotic system. Its effectiveness was evaluated with the visual analog scale (VAS), WOMAC score, Lequesne index, Harris Hip Score, goniometry, and biomechanical gait analysis. RESULTS: All groups demonstrated positive trends, though the degree of improvement depended on the presence and type of comorbidity. The most pronounced results were observed in the control group: VAS decreased from 5.56 ± 0.82 to 1.21 ± 0.07; flexion angle improved from 122.06 ± 3.39° to 95.58 ± 1.27°; Lequesne index decreased from 14.42 ± 0.33 to 7.24 ± 0.16; Harris Hip Score improved from 47.90 ± 1.55 to 79.92 ± 0.75; WOMAC score improved from 48.36 ± 1.54 to 13.42 ± 1.04. In patients with HT, DM, and OW, the trends were less pronounced: pain reduction was from 5.62 ± 0.95 to 1.45 ± 0.09, from 5.89 ± 0.98 to 1.68 ± 0.11, and from 5.93 ± 1.01 to 1.89 ± 0.12 points, respectively. The smallest functional gain was observed in OW patients (WOMAC: 48.33 ± 1.53 to 24.74 ± 3.47). CONCLUSION: The presence of comorbid conditions slows functional recovery after TAMLJ. The implementation of robotic mechanotherapy into early postoperative rehabilitation improves its effectiveness.
Comparative evaluation of the efficacy and safety of combination drugs in wound healing and wound infection control in blast injuries, gunshot injuries, and diabetic foot
BACKGROUND: Infected wounds, including those resulting from blast and gunshot injuries as well as diabetic foot, are a significant medical concern due to the high risk of complications and the need for long-term care. Therefore, the search for effective and safe topical therapies remains relevant. We performed a comparative evaluation of the efficacy of selected combination antimicrobial drugs and an antiseptic in treating such wounds, analyzing their effects on tissue regeneration, microbial burden, and clinical outcomes. AIM: The work aimed to assess the efficacy and safety of dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin, dioxomethyltetrahydropyrimidine + chloramphenicol, and povidone-iodine in the treatment of infected wounds of various etiologies. METHODS: A single-center, open-label, non-interventional, observational, randomized controlled study was conducted in 60 patients (40 with blast/gunshot injuries and 20 with diabetic foot). Three drug products were selected for comparison: dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin (Oflomelid, Sintez, Russia); dioxomethyltetrahydropyrimidine + chloramphenicol (Levomecol, Nizhpharm, Russia); and povidone-iodine (Betadine, Egis, Hungary). Treatment involved daily wound care throughout the observation period. Treatment outcomes included changes in wound healing (area, depth, exudate volume), pain intensity, and microbiological and biochemical parameters. RESULTS: Dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin was associated with significantly greater changes in wound healing: reduction in wound area (p < 0.001) and depth (p = 0.008), and decreased exudate volume (72.7% of patients without exudate by visit 4). Pain reduction was also more pronounced in the dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin group (p < 0.001). All therapies effectively suppressed the growth of Staphylococcus aureus; however, combination antimicrobial drugs outperformed the antiseptic by approximately 20%. Laboratory parameters improved in all groups, with antistreptolysin-O levels decreasing more significantly in the dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin group (p = 0.009). CONCLUSION: All evaluated therapies were effective and safe; however, dioxomethyltetrahydropyrimidine + lidocaine + ofloxacin demonstrated superior results for key outcomes: accelerated wound healing, reduced bacterial load, and improved subjective therapy assessments. This combination drug (antibiotic + regenerative agent + anesthetic) has the potential to become the treatment of choice for complex infected wounds, such as those caused by trauma or diabetic foot.
Treatment experience of congenital radioulnar synostosis in children: case reports
INTRODUCTION: Congenital radioulnar synostosis is a rare orphan condition that impairs a child’s ability to adapt to everyday life and causes difficulties in acquiring writing and hygiene skills. Parents of children with this condition typically note a pronated position of the forearm and hand, along with the absence of rotational movements in the forearm. The diagnosis is based on radiographs of the forearm, and the type of synostosis is determined according to the Cleary–Omer classification. There is no conservative treatment for this condition. Over 20 surgical techniques have been described, which makes the indications and choice of a particular surgical method a subject of ongoing debate. CASE DESCRIPTION: This paper presents the clinical experience of treating congenital radioulnar synostosis in 12 children between January 2018 and March 2024. A total of 16 surgical procedures were performed: 14 derotational osteotomies at the synostosis level according to the Green technique with wire fixation, and 2 procedures using a combined method involving derotational osteotomy at the synostosis level with wire fixation and a corrective radial osteotomy in the middle third with plate fixation. The surgical technique and specific features of the fixation method are described in detail. Possible complications are discussed. Treatment outcomes were evaluated over a follow-up period ranging from 1 to 5 years postoperatively. All patients achieved functional positioning of the forearm in the neutral position, improved quality of life, and acquired new hygiene and learning skills. In the postoperative period, transient neuropathy of the deep branch of the radial nerve was observed in 5 out of 16 surgical interventions for congenital radioulnar synostosis, manifested by finger extensor paresis. One case of delayed consolidation was also noted following the two-level osteotomy. CONCLUSION: Treatment of radioulnar synostosis at a younger age is less traumatic, as the deformity is not multiplanar and does not require additional corrective elements beyond forearm derotation. This procedure is effective in eliminating the pronated position of the limb and improving functional capacity without causing serious complications. Although the risk of complications increases with age at the time of correction, no statistically significant association was found. The current sample requires expansion for more accurate comparison of surgical techniques.
Two-stage treatment of neglected perilunate wrist dislocations
INTRODUCTION: The treatment of neglected perilunate dislocations of the wrist remains a complex challenge for surgeons. To address this issue, hand surgeons have several options in their arsenal: open reduction, lunate excision, proximal row carpectomy, arthrodesis, and arthroplasty. Open reduction appears to be an attractive approach, as it allows restoring normal wrist anatomy with preserving the possibility of future procedures in case of failure. However, there is no consensus among contemporary surgeons regarding the acceptable time interval between injury and surgery. Likewise, opinions differ on the technique of reduction itself. CASE DESCRIPTION: The treatment of 8 patients aged 24 to 42 years with neglected perilunate dislocations was analyzed. The interval between injury and surgery ranged from 1.5 to 19 months. The first stage involved application of an Ilizarov external fixator for gradual preoperative distraction of the wrist joint. After 2–4 weeks, the Ilizarov external fixator was removed, and open reduction followed by fixation with wires was performed. At the second stage, in three cases, scaphoid osteosynthesis with a screw and free bone grafting were additionally performed. In all cases, gradual distraction enabled progressive soft tissue elongation without ischemic or neurological complications. At the second stage, all perilunate dislocations were successfully reduced via open approach. Functional outcomes were assessed 6 to 60 months after open reduction using the Mayo wrist score. Hand function improved in 6 patients (60–80 points) and was fully restored in 2 patients with a 1.5-month injury duration (100 points). In patients (3) with scaphoid pseudarthrosis, bone union was achieved. In the long-term follow-up, 3 patients developed radiological signs of post-traumatic wrist osteoarthritis, including partial resorption of the lunate, capitate, and hamate in 2 cases. CONCLUSION: Preliminary wrist joint distraction facilitated and simplified the performance of open reduction of neglected perilunate dislocations of the carpal bones. The functional outcome in our patients depended on the time elapsed since injury and the presence of associated carpal fractures. The question of a time limit after injury for which open reduction remains a justifiable option remains unresolved.
Review of contemporary robotic systems used in total knee arthroplasty
Recent advances in orthopedic technologies have significantly increased surgeons’ interest in robotic systems used for total knee arthroplasty. The use of robotic platforms in routine clinical practice enhances the precision of implant component positioning, improves soft tissue balance, and potentially shortens postoperative recovery time. This work aimed to provide a comparative overview of modern robotic systems utilized in primary total knee arthroplasty. A systematic search of scientific data was conducted in the PubMed, Scopus, ResearchGate, and eLIBRARY databases using relevant keywords in both Russian and English. The review includes randomized and non-randomized studies, meta-analyses, narrative reviews, and systematic reviews published over the past five years. Active and semi-active systems are identified and described in detail, along with their operating mechanisms, features of preoperative planning (image-based vs image-less), and differences between open and closed platforms. Comparative characteristics of the most widely used systems—ROSA, MAKO, VELYS, CORI, and Cuvis Joint—are presented, highlighting their advantages and limitations according to our opinion. The analysis demonstrates that none of the systems is universal; each has its own strengths and weaknesses, and the choice depends on the surgeon’s preferences, the team’s experience, and the capabilities of the medical institution. Despite the high cost of equipment and the need for specialized training, robotic technologies continue to develop rapidly and are being increasingly adopted in orthopedic surgery, including in Russia, underscoring their potential to improve treatment outcomes for patients with gonarthrosis.

Sagittal morphology of the spine and its predictive role in the pathogenesis of degenerative conditions. Historical aspects and contemporary views on the problem
Bipedalism in humans is linked to the need for constant horizontal gaze maintenance and an ergonomic vertical posture. These physiological characteristics of Homo sapiens are made possible by three reciprocal sagittal curvatures of the spine, the profile configuration of which, as studies have shown, exhibits considerable variability in the population of healthy individuals. The issue of systematizing the sagittal morphology of the spinopelvic complex, considering its constitutional ambiguity, has been a subject of increasing attention among researchers since the mid-1970s. The classification proposed by Roussouly in 2005 can be considered the quintessence of the accumulated global experience. In addition to systematizing the profile configuration of the spine, the author placed significant emphasis on the biomechanical specificity of its morphotypes and their predictive role in the pathogenesis of degenerative diseases. The problem of sagittal morphology variability and its morphotyping remains relevant to this day and is the subject of numerous scientific discussions. However, forming a comprehensive understanding of this issue is difficult due to the narrow focus of the conclusions and the lack of systematic works. The present review is analytical in nature and was conducted using medical scientific databases and search resources such as PubMed and eLibrary. The article explores the historical aspects of the formation of the concept of the spinopelvic complex morphotyping, as well as analyzes the predictive role of sagittal biomechanics of the spine in the pathogenesis of its degenerative condition.
From acquired flatfoot to progressive collapsing foot deformity: a review of classifications
Flatfoot deformity has historically been a complex problem, characterized by a combination of multiplanar deviations. To date, a wide range of classifications has been proposed, based on various principles—from posterior tibial tendon dysfunction, historically considered the primary cause of deformity, to segmentation by foot regions and specific types of deformities within them. A major challenge lies in the fact that foot deformity, as described below, does not follow a linear pattern, and various deformity combinations frequently occur, complicating its systematization. The work aimed to analyze existing and most widely used classifications of flatfoot deformity that have been proposed at different times and remain relevant in foot and ankle surgery, with emphasis on their features and limitations. A scientific data review was conducted using PubMed, eLIBRARY.RU, and CyberLeninka databases with the search terms классификация плосковальгусной деформации / classification of flatfoot deformity and flatfoot deformity. A total of 12 sources were selected for the review. The analyzed scientific data covered the period from 1988 to 2025. In the course of the review, an evident trend was identified toward more detailed segmentation of the deformity by different regions of the foot and the types of abnormalities within them. We observed a shift from hierarchical to faceted classifications, reflecting attempts to encompass the wide variability of deformities across all foot regions and their combinations encountered in clinical practice. And despite numerous attempts at systematization, there is still no universal classification that fully reflects all aspects of flatfoot deformity and satisfies the needs of clinicians in determining patient management strategies for this condition.
Renander–Müller disease: current state of the problem
This scientific data review addresses the issues of diagnosis and treatment of avascular necrosis of the sesamoid bones, also known as Renander–Müller disease. This condition is relatively rare and predominantly affects physically active young individuals. The combination of these two factors contributes to diagnostic challenges, persistent functional impairment, and a high rate of disability. No publications on this condition were found in Russian. The scientific data search was conducted using the PubMed, Medline, Scopus, Google Scholar, and eLIBRARY databases. A total of 47 publications were included in the review. The search was performed using the following keywords, their derivatives, and combinations in the titles and abstracts: avascular necrosis of the sesamoid, sesamoid AVN, hallucial sesamoid disorders, Renander–Müller disease, osteonecrosis, sesamoidectomy, and sesamoid. The initial screening for inclusion criteria was conducted using the titles and abstracts, followed by full-text analysis of the selected articles. Sources without accessible full-text versions were excluded from the analysis.
Prospects for the use of radiolucent materials in the design of external fixation devices
The use of radiolucent materials represents a relevant direction in the search for new technological solutions aimed at improving the performance characteristics of medical devices. This work presents a review and an analysis of the feasibility of using modern composite materials with radiolucent properties in external fixation devices (EFD). The most significant aspects of polymer composite application in medical devices are highlighted. The physical, mechanical, and radiological properties of composite materials best suited for the production of rod-beam and ring fixation systems are described. An additional advantage of radiolucent external fixation devices is their light weight, which is ensured by the lower density of polymer materials, serving as matrices for the composites used to manufacture EFD components, compared with metal alloys. The possibility of autoclave sterilization of polymer composite products is demonstrated, indicating their potential use as components of external fixation systems. Clinical cases involving external fixators with radiolucent components are reviewed, along with examples of commercially available (mass-produced) external fixation devices. The potential for 3D printing to be used in manufacturing EFD components is shown, although it is not currently considered a primary method for EFD production. Radiolucent external fixation devices made from modern composite materials enhance fracture reduction, allow for targeted radiotherapy at required doses, and improve radiographic visualization during intraoperative and postoperative periods. These benefits enable timely treatment adjustments and help reduce the risk of complications. This makes their development a promising scientific and industrial avenue aimed at solving specific clinical problems.
