Purpose of the study — to compare management efficiency for difficult-to-treat periprosthetic hip joint infection (PJI) during resection arthroplasty with grafting by vastus lateralis pedicle island flap in comparison with insertion of an antimicrobial-loaded cement spacer. Material and Methods. 132 patients were included into the retrospective study who underwent treatment from 2012 until 2018 including removal of orthopaedic implant, radical surgical debridement of infection focus, resection arthroplasty with grafting by vastus lateralis pedicle island muscle flap (PMF group — 57 patients) or insertion of antibacterial-loaded cement spacer (AMS group — 75 patients). The authors examined medical histories, nature of infection process, infection agent type, laboratory data in respect of systemic inflammation, size of bone defects, follow up status and remission of PJI in the late period. Results. 89.4% of patients (n = 51) who underwent grafting by vastus lateralis pedicle island flap had a history of 3 and more prior surgical procedures in the same area. At the same time the share of such patients in the spacer group was only 38.6% (n = 29) (p

Purpose of the study — to provide an anatomical rationale and evaluate the clinical application of posterolateral surgical approach with osteotomy of the fibular head for internal fixation of the posterior aspect of the lateral tibial condyle. Material and Methods. Anatomical topography research was performed on 14 lower limbs of 8 fresh cadavers. In the first series of research L-shaped plate was fixed on the posterolateral surface of lateral tibial condyle from the examined approach, then preparation was performed and measuring of distances from various parts of the plates to the common peroneal nerve and anterior tibial artery. In the second series the authors prepared histological topograms by transverse sectioning of plastinated specimens from the knee joint area after implantation of L-shaped buttress plates. Prospective observation clinical study included 20 patients who underwent internal fixation with L-shaped buttress plate from the examined approach for fracture of the posterolateral column of the tibial plateau, type 41В by AO classification. KSS and Lysholm scales were used to evaluate treatment outcomes at days 7–10 and in 1, 3, 6 and 9 months postoperatively. Data of the anatomical and clinical research was compared. Results. Compliance with the technique of posterolateral transfibular surgical approach allows to avoid risk of injury to the common peroneal nerve and anterior tibial arthery which on the specimen were always located safely away from implanted plates. All 20 clinical cases demonstrated good visualization of bone fragments and articular surface of the tibial plateau which ensured reliable reduction and fixation by L-shaped buttress plate. KSS excellent and good outcome scores amounted to 50% and 45%, respectively, while satisfactory score was reported in 5% of cases; Lysholm scale demonstrated 55% of excellent outcomes, 45% of good outcomes, and 5% of satisfactory outcomes. Safety of the approach was verified: no injuries to large blood vessels or iatrogenic neuropathies were reported as well as no large hematomas or infectious complications of the surgical wound in early postoperative period. Conclusion. Results of the present study proved the feasibility and safety of the posterolateral transfibular surgical approach for internal fixation procedures in patients with intraarticular fractures of posterolateral column of the tibial plateau.

The authors present a short analysis of autoabstracts of all theses in traumatology and orthopedics speciality (14.01.15), 10 doctoral and 59 candidate theses, that were defended at 11 dedicated dissertation boards starting mid of October 2016 until mid of October 2017 and underwent expert reviews during 2017 in expert council of the Higher certifying commission on surgical science.The absolute majority of 26 papers in traumatology (16 candidate and 5 doctoral theses) were dedicated to treatment of patients with different fractures and another 5 candidate theses examined issues of arthroscopic procedures in case of a trauma. 25 dissertations in orthopedics mainly reviewed aspects of large joints replacement (6 candidate and 3 doctoral these) and treatment of periprosthetic infection (4 candidate theses). Spine pathologies (5 candidate theses) and oncology orthopedics (2 candidate theses) prevailed among dissertation topics on paediatric orthopedics. The only doctoral thesis on paediatric orthopaedics was dedicated to clubfoot.In accordance with recommended criteria of clinical Orthopaedics and Related Research journal 40 (67,8%) candidate theses and 2 (20%) doctoral theses corresponded to evidence level III, 17 (28,8%) candidate and 8 (80%) doctoral theses were classified as evidence level IV and only 2 candidate theses (3,4%) formally corresponded to evidence level II.

The authors performed an analysis of published stadies devoted to osteoporosis situation in Russian Federation including epidemiological, social, medical and economical aspects of this pathology. The analysis demonstrated that osteoporosis is reported in every third woman and every forth man of 50 years old and older. Seven vertebra fractures happen every minute and one fracture of proximal femur — every 5 minutes in Russia. An overall number of all key osteoporotic fractures will increase from 590 thousand up to 730 thousand cases by the year 2035. Osteoporosis is financially demanding for healthcare due to high treatment cost of fractures that are accompanied by life quality deterioration, high mortality and invalidization of patients. Epidemiological studies demonstrated that due to high fracture risk the osteoporosis therapy should be assigned to 31% of female and 4% of male patients over 50 years old. Such factors of osteoporosis risks are widespread in the society: smoking, low food calcium consumption, vitamin D deficit, low physical activity. The authors analyzed the problems in organization of medical care to patients with osteoporosis and osteoporotic fractures and possible solutions to existing issues. The organization of healthcare should be addressed at identification of high risk patient groups, early diagnosis and assignment of corresponding treatment aimed at decreasing potential fracture risk as well as at pathology prophylaxis.

Based on the analysis of the scientific heritage the authors presented the contribution of the great Russian surgeon N.I. Pirogov in the development of surgery of the locomotor system. Discussed in detail next lines of activity of N.I. Pirogov being of interest of trauma and orthopedic surgeons, in particular the: anatomical and physiological approach to studying the issues of surgery of extremities, development of scientific and organizational bases in the domestic military-field surgery, the Pirogov's ideas in the field of reconstructive surgery of the extremities, as well as its contribution to the reforming of surgical education in Russia and improvement of the domestic surgical instruments.

In order to justify a new method of surgical treatment of patients with recurrent and chronic Achilles tendon ruptures conducted applied topographic-anatomic study of 12 fixed and 8 fixed preparations of the lower extremities was performed. In the developed technique were carried out operations in 18 patients aged from 30 to 72 years with repeated ruptures Achilles tendon. The results of treatment were followed-up in all 18 patients in the period from 6 months to 3 years. Repeated tears of Achilles tendon were not observed. The range of motions in ankle joint reconstructed almost in its entirety. Performed topographic and anatomical studies and accumulated clinical experience allow us to recommend the proposed method for a wider clinical use.

The applied topographic-anatomic studies prepared in 14 fixed and 16 unfixed preparations of upper extremity allowed to precise the details of radius blood supply with reference to possibilities of formation of bone autografts with blood supply. Due to this fact the novel method of single-stage bone plasty for pseudoarthrosis of both forearm bones was developed and successfully approved in clinic. This method proposes the formation of two periosteal-cortical grafts with blood supply and small muscle cuff in distal and middle one-thirds of radius simultaneously.

29 women with postmenopausal osteoporosis, complicated by compression vertebral fractures were treated by infusion of zoledronic acid, 5 mg. The results were assessed using dual-energy X-ray absorptiometry. By 12 months BMD increased both in lumbar spine (mean 5,2% (σ=0,17) and in femoral neck (mean 3,9% (σ=0,20)); by 24 month the mean increase were 6,3% и 4,0% (σ=0,33) respectively. No new compression vertebral fractures were found.

Applied topographic-anatomical studies were carried out on 12 fixed lower extremities and revealed that in the anterior portion of the middle gluteus muscle 4 cm in width the upper branches of the gluteal vessels are always held supplying the area of the iliac crest. Taking into account the received data the authors proposed a new method of femoral neck osteosynthesis with non-free autoplasty by the autograft from the iliac crest, which is moved at constant muscle-vascular supply pin and fixed with screw in the fracture. Osteosynthesis using the proposed method was performed in 24 patients and provided the union of fractures in all cases in a period of 5 to 8 months. Analysis of long-term results of treatment of 22 patients performed 3 years after the operations showed good function of injured joints and no evidence of avascular necrosis of the femoral head in 18 (83.3%) cases.

Applied topographic and anatomic studies on 12 lower limbs of seven premature stillborn children have allowed to substantiate the possibility of formation and free transplantation in children of the epimethadiaphyseal fibula graft with two blood supply sources. In view of the obtained data, it has been developed and successfully tested clinically the original reconstructive microsurgical operation, which allows to replace in children simultaneously extensive (more than 50% of length) defects of the distal radius with preservation of function of the growth plate of the transplanted bone.

Relying on studies of scientific publications we have analyzed possibilities and effectiveness of using various modern techniques of replacement of major posttraumatic defects of tissues of extremities and we have worked out the main lines of improving the treatment of this category of patients.

Background. Minimally invasive surgical interventions are widely used in trauma and orthopedic surgery. Both the surgical technique and the instruments applied are being improved, which contributes to better functional results of patients’ treatment. Aim of the study — to present a new guide tool for minimally invasive surgical correction of acquired hallux valgus. Guide description. A guide tool intended to be used in minimally invasive surgical interventions for hallux valgus (HV) correction has been developed. It consists of several interconnecting components: the distal bar, the intramedullary guide, the proximal bar, and the wire guide. These components are fixed to each other. At the same time, the distal bar, the proximal bar, and the wire guide are connected with the possibility of adjusting their mutual positioning. The design of the proposed device enables to guide the first guiding wire and to place the cannulated screw in an optimal position. The presented clinical case illustrates the successful application of the described device. The patient underwent minimally invasive distal corrective osteotomy for hallux valgus of medium severity. According to the preoperative X-rays, the first intermetatarsal angle and the first toe deviation angle were 13.5° and 25°, respectively. Six months after the surgery, they were 3° and 7°, respectively. The result of the corrective surgery was considered excellent. Conclusion. Application of the proposed guide tool decreases surgery duration, reduces soft tissue damage and minimizes radiation exposure of the surgeon and the patient.

The article presents a discussion with the authors of a previously published article (Zelyanin D.A. et al. Features of the Extraction of the Anterior Tibial Vessels in the Formation of Vascularized Bone Grafts. Traumatology and Orthopedics of Russia. 2022. Vol. 28, No 1. p. 89-99), as well as on the basis of our own topographic and anatomical studies, the information about the details of the topography of the branches of the anterior tibial vascular bundle (ATVB) and the permissible levels of its proximal mobilization during island flaps transfer are justified. Topographic and anatomical study was performed on 32 non-fixed speciments of the lower extremities for substantiating plastic surgery with island skin flaps isolated on ATVB. The arterial bed of the lower leg was injected with black natural latex Revultex, followed by precision dissection and measurements of all branches of the anterior tibial artery (ATA) with a diameter of 0.3 mm or more using a binocular magnifier with a magnification of 3.3 times. All the studied branches of ATA were identified, the number of which varied from 26 to 49 (on average 38.53.2), and 88.7% of them went to the three muscles of the anterior group of the lower leg. At the same time, the average numbers of ATA branches departing in each of the 10% intervals of the length of the lower leg were determined, and the average total values of the cross-sectional area of arterial branches in these intervals were calculated. It was found that from 28% to 39% of the total cross-section of all branches of the ATA are localized in the first and second 10% intervals of the length of the lower leg, which makes it possible to justify the proximal limit of the mobilization of the ATVB. Reasonable criteria for choosing the level of proximal mobilization of the ATVB are: the location of the mobilization border is not higher than the level of the upper 20% of the length of the lower leg, the assignment of this border, at least 6 cm distal from the exit of the anterior tibial vessels into the anterior bone fascial sheath of the lower leg and the preservation of at least four feeding vascular bundles extending from the ATVB to the tibialis anterior muscle (two bundles) and to the extensor digitorum longus muscle (two bundles).

Background. Surgical treatment of malleoli injuries is performed according to the principles of articular fractures management. It is particularly true for ankle injuries involving fractures of posterior edge of the tibia. The posteromedial approach enables to improve the results of surgical treatment of patients due to the direct reduction of tibia fragments. Aim of the study to evaluate the efficacy and advisability of the modified posteromedial approach in patients with unstable fractures of malleoli and posterior edge of the tibia. Methods. Twenty two patients with unstable fractures of malleoli and posterior edge of the tibia underwent surgical treatment via the posteromedial approach. The X-ray control was performed the next day after the surgery as well as 6, 12, 24 and 48 weeks from the osteosynthesis. The functional results were evaluated in 12, 24 and 48 weeks after the surgery with the use of AOFAS and Neer scales. Results. The average duration of postoperative period (9.33.8 days) was mainly determined by the state of the soft tissues. 91% of patients had anatomical reduction of posterior edge fragment of the tibia, 17 (77%) from 22 patients demonstrated fracture consolidation in X-rays 12 weeks after the surgery and all 22 patients (100%) 24 weeks after surgery. There were no cases of postoperative complications in patients 24 weeks after the surgery. While managing patients the range of motion in the ankle joint increased from 41.16.9 12 weeks after the surgery to 57.34.6 48 weeks after the surgery, that was statistically significant (p0.01). The functional results improved as well according to both AOFAS and Neer scales and this improvement was also statistically significant (p0.01). Conclusion. The is rather effective in Patients with unstable fractures of malleoli and posterior edge of the tibia had a statistically significant improvement in function after posteromedial approach.

Background. Protein-energy malnutrition (PEM) is an established risk factor of postoperative complications in orthopedic disorders, including arthroplasty of the large joints. The study aimed to evaluate PEM prevalence and its association with the early postoperative revision in patients with the difficult-to-treat (DTT) prosthetic joint infection (PJI) of the hip. Methods. The retrospective study included 132 patients with chronic DTT PJI of the hip. The patients underwent orthopedic implant removal, radical debridement of the infected tissues, and resection arthroplasty with non-free transplantation of an axial vastus lateralis muscle flap (n = 57) or installation of an antimicrobial spacer (n = 75). DTT PJI was defined as an infection caused by rifampicin-resistant staphylococcal strains, ciprofloxacin-resistant gram-negative bacteria, fungi of the genus Candida, and their associations. The assessment of the patients protein-energy status included the evaluation of reference laboratory parameters, such as levels of hemoglobin, total protein, and albumin and number of lymphocytes. The degree of PEM was determined by the number of laboratory markers below the threshold values. The statistical comparison was performed using Fishers test. The odds ratio (OR, 95% confidence interval [CI]) was calculated to assess the risk of PJI recurrence. Differences were considered significant at p0.05. Results. More than 70% of patients with chronic DTT PJI included in the study were diagnosed with preoperative PEM of varying degrees of severity. Hypoalbuminemia and decreased hemoglobin levels were diagnosed more often: 64.3% and 57.1% in the muscle flap plasty and 57.3% and 31.1% in the antimicrobial spacer group, respectively. In muscle plasty and antimicrobial spacer groups, a decrease in the values of three or more reference PEM markers was detected in 28.5% and 16.0% of patients, and this advanced impairment of the nutritional status increased the risk of early revision intervention by two (OR 2.0; CI 95% 0.478.56; p = 0.35) and six times (OR 6.11; 95% CI 1.0635.35; p0.04), respectively. Conclusion. In general, the analysis of publications and results of our study show that PEM is associated with the development of surgical site infection and recurrence of PJI after revision surgery. A decrease in the values of three or more reference PEM markers is a significant predictor of repeated revisions after debridement surgery with the installation of an antimicrobial spacer. PEM complicates the postoperative course in patients with resection arthroplasty. Given the high incidence of PEM in patients with DTT PJI of the hip joint, further research is needed to develop methods for nutritional status correction and assessment of their effect on the outcomes of debridement surgery.

The malleoli fractures in combination with the fractures of posterior edge of the tibia are considered unstable injuries and present particular difficulties in surgical treatment. The aim of the study was to evaluate short-term and mid-term results of osteosynthesis on account of unstable fractures of malleoli and posterior edge of the tibia using posterolateral surgical approach. Materials and Methods. The analysis of short-term and mid-term results of the treatment of 29 patients with malleoli fractures types 44-B3 and 44-C1.3, C2.3 and C3.3 (according to the AO classification) with the involvement of the Volkman`s posterior tibia fragment was performed in traumatology departments of three hospitals during the period from January 2019 to September 2020. In all 29 cases the fracture of the posterior edge of the tibia was classified as type 1 according to the classification of N. Haraguchi et al. All patients underwent osteosynthesis of the posterior edge of the tibia and the lateral malleolus via posterolateral surgical approach. Combined fracture of the medial malleolus was fixed via classical medial approach. 5 patients (17.2%) with continued instability of the distal tibiofibular syndesmosis underwent fixation with positional screw. Functional results, as well as the range of motions in the ankle joint were evaluated with the use of AOFAS and Neer scales 3, 6 and 12 months after surgery. Results. Statistically significant improvement in functional outcomes over time was noted when evaluated on the AOFAS scale (p0.05) and on the Neer scale (p0.01). 12 months after the surgery these points were 83.213.4 and 87.816.8 respectively. Complications were noted in 5 patients (17.24%). Deep periimplant infection was registered just in one case, another patient had marginal necrosis of the operative wound. Three patients had clinically significant post-traumatic deforming arthritis of the ankle joint. Conclusion. Posterolateral surgical approach has advantages when performing osteosynthesis in patients of the studied profile and enables anatomical reduction and stable fixation of fragments of the Volkman`s posterior edge of the tibia, which provides the possibility of early mobilization of the ankle joint and has positive effect on the results of treatment.
