Bone Tissue Remodeling

Using standard photodensitometry bone remodeling was studied in proximal tibia and distal femur after total knee arthroplasty at terms up to 12 months. Out of 120 patients 60 patients (main group) received strontium ranelate (Bivalos) for 12 months after operation and in 60 patients (control group) drug correction was not performed. By the results of standard photodensitometry in both patient groups the density of radiographic image around the implant decreased by 22% at an average within the first 2 postoperative months and that was indicative of osteolysis activity. Later on during the period from 2 to 6 months after arthroplasty the increase of optic bone density was observed. By the end of 12 month in patients from the main group the optic bone density around the implant increased by 39.6% (to preoperative level) and by 25% in controls as compared with the level recorded in 2 months after surgery. Analysis of the total knee replacement by Lischolm scale showed that drug optimization of the processes of bone tissue remodeling enabled to shorten the terms of patients' rehabilitation and to decrease the rate of unsatisfactory results.

Assessment of the alendronate influence upon the course of adaptive remodeling of bone tissue adjacent to the implant was performed. Dynamics of mineral bone density (BMD) changes in Gruen zones was compared for 2 groups of female patients. The groups were similar by age, nosology. All operations were performed by the same surgical team with application of one type of implant (Zweymuller). During the first post-operative year patients from the study group (n=38) were taken alendronate (Fosamax-70) once a week and at least 1200 mg of calcium carbonate daily (either as calcium containing food products or calcium carbonate preparations). Patients from control group (n=94) were taken only calcium carbonate by the same scheme within the first postoperative year. It was detected that although by 6th postoperative month alendronate did not decraese BMD loss as compared to controls, within the interval of 6-15 months it significantly increased bone tissue mass accretion. In group of alendronate patients monthly accretion of bone tissue in some Gruen zones (except for R4) was twice and more higher than in control group. Fifteen months later patients from the main group showed BMD deficit only in R4 zone. In the rest of zones bone tissue mass exceeded the basic values and in the majority of zones that increase was trustworthy. In control group BMD deficit was preserved in two proximal zones (R6 and R7) and in zone R6 it even increased as compared to the results of the previous study (12 months after operation).

Results of comparative study of the efficacy and safety of intraoperative application of tranexam versus autoplasma in patients with planned surgical blood loss and high risk of venous thrombosis development has been presented. One hundred seven patients admitted for total knee replacement were divided into 2 groups. In the main group (55 patients) intraoperative intravenous infusion of 10 mg/kg tranexam were used. In the control group (52 patients) intraoperative hemodilution with autoplasma was performed. Hemostasis indices (APTT, INR, SFMC, D- dimer) and lysis index were studied before surgery and in postoperative period. Ultrasound scanning of lower extremity veins was performed before surgery and in 4—5 days after intervention. The volume of intraoperative blood loss in two groups did not differ. In the postoperative period the drainage blood loss in the main group was more than twice lower as compared to the control group (p=0,037). In postoperative period statistically significant increase in SFMC and D-dimer indices was noted in both groups. However after tranexam application the increase in fibrin lysis products content was reliably less marked than in control group. US investigation of lower extremities showed distal veins thrombosis in 2 patients from control group and no cases of thrombosis in the main group.

Introduction. Total knee replacement has become a standard planned intervention at specialized clinics. The study of surgical results is not as urgent as the follow up of the patients with concomitant pathology because various complications are most often registered in this group. Purpose: to evaluate the efficacy of total knee arthroplasty in patients with increased body mass index at early rehabilitation steps. Patients and methods. Open prospective comparative study included 75 patients with III-IV stages of gonarthrosis by Kellgren-Lawrence. Mean age of the patients made up 63.8±6.87 years. Main group included 48 patients with excessive body mass and alimentary-constitutional obesity of different degree, the control group - 27 patients with normal body mass index. The duration of intervention, volume of blood loss intraoperatively and drainages was assessed. Evaluation of clinical functional results was performed OKS, KSS and visual analog scale (VAS) before surgery, at discharge, 3 months and 1 year after surgical intervention. Results. In comparison to the patients with normal body mass index the patients from the main group showed slightly higher duration of the intervention and intraoperative blood loss - by 13.05% (p=0.027) and 12.8% (p=0.003), respectively. In the main group the severity of pain syndrome by VAS decreased from 90.4±14.4 to 9.6±0.4 mm (p=0.0001), evaluation of clinical functional results by KSS increased from 47.39±1.63 to 88.02±2.01 points, by OKS - from27.3±4.3 to 43.2±6.5 points (p=0.001). In the control group the severity of pain syndrome by VAS within 1 year follow up decreased from 86.2±2.4 to 3.8±0.7 mm (p=0.002) and clinical functional indices by KSS increased from 52.2±10.1 to 93.8±1.3 points (p=0.001), by OKS - from28.4±1.6 to 44.7±1.9 points (p=0,001). Conclusion. The study results demonstrate the high potentialities of arthroplasty in patients with alimentary obesity and confirm the necessity of its performance for the improvement of the patients’ future quality of life.

Abstract Background Osteoporosis (OP) and osteoarthritis (OA) commonly coexist in postmenopausal females. The decrease in bone density and increase in bone resorption in postmenopausal females with OP may consequently affect the surgical outcome of total knee arthroplasty (TKA). However, clinicians often ignore monitoring the treatment of OP in the perioperative management of TKA. Bone turnover marker (BTM) can timely and accurately reflect bone metabolism to monitor the treatment of OP. The purpose of this study was to investigate the effect of BTM monitoring to guide the treatment of OP in postmenopausal females undergoing TKA. Methods Postmenopausal females with OP who underwent primary unilateral TKA were randomly divided into two groups (monitoring group and control group), given oral medication (alendronate, calcitriol, and calcium), and followed for 1 year. In the monitoring group, serum BTMs (C-telopeptide of type I collagen (CTX-I), N-terminal propeptide of type I procollagen (PINP), and 25(OH)D) were assessed preoperatively and repeated postoperatively; alendronate was withdrawn when CTX-I and PINP reached the reference interval; and calcitriol and calcium were withdrawn when 25(OH)D reached the reference interval. In the control group, oral medication was implemented for a uniform duration of 3 months. During the 1-year follow-up, the mean maximum total point motion (MTPM) of the tibial component, bone mineral density (BMD), visual analog scale (VAS) score, range of motion, and Oxford Knee Score (OKS) score were obtained. Results In the monitoring group, BTM monitoring prolonged the medication duration, but did not cause more adverse reactions than in the control group. The mean MTPM values at 6 m and 12 m in the monitoring group were lower than those in the control group, and the BMD at 12 m in the monitoring group was significantly higher than that in the control group. Patients in the monitoring group had lower VAS scores at 6 m and higher OKS scores at 6 m and 12 m than those in the control group. Conclusion In postmenopausal females with osteoporosis undergoing primary TKA, the application of BTM monitoring to guide the treatment of osteoporosis can enhance bone density, maintain prosthesis stability, and improve surgical outcome.

Introduction. Glaucoma is one of the most significant eye diseases. It is often diagnosed, not always amenable to therapy, and can lead to a complete loss of visual functions. In recent years, the method of osteopathic correction has become widespread as one of the effective methods of treatment and rehabilitation of patients with pathologies of various body systems. In the pathogenesis of glaucoma, it is customary to distinguish a dystrophic concept, which considers primary open-angle glaucoma as a result of dystrophic changes in the connective tissue, as well as in the endothelial lining of the trabeculae and Schlemm′s canal, especially destructive changes in mitochondria and the alteration of their functional activity. A vascular concept is also distinguished. According to this concept, the central link in the pathogenesis of glaucoma is circulatory disorder in the ciliary vessels, ocular artery, and major vessels of the head and neck, it can be assumed that osteopathic correction in the treatment of patients with open-angle glaucoma will be pathogenetically substantiated and will have a positive effect on intraocular pressure and trophicity of the optic nerve. The goal of research — to study the influence of in osteopathic correction on the nature of unoperated glaucoma (stage IIA) and to substantiate the possibility of using osteopathic correction in the complex treatment of patients with this pathology.Materials and methods. A prospective controlled randomized study was conducted at 52 city polyclinics, branch 3, Moscow, from January 2018 to January 2019. 40 patients (70 eyes) aged 50 to 75 years with primary open-angle glaucoma IIA stage were examined. At this stage of the disease, patients most often seek medical care and the issue of conservative management is primarily considered. All patients were divided into two groups of 20 people: the main group and the control group. The treatment in the main group included hypotensive drug therapy and osteopathic correction. Patients of the control group received only drug therapy. All patients underwent ophthalmic (visometry, tonometry, perimetry) and osteopathic examination twice: before the treatment and after 3 months.Results. For patients with primary open-angle IIA non-operated glaucoma, regional (most often regions of the head, neck, dura mater) and local (abdominal diaphragm, iliac bones, hip and knee joints) somatic dysfunctions were the most typical. In the main group a statistically significant decrease in the frequency and severity of dysfunctions at all levels was stated. Also, in patients receiving osteopathic correction, a significant decrease in the level of intraocular pressure and perimetric indices was noted. In patients of the control group, no reliable changes in these indicators were obtained.Conclusion. The results obtained indicate that osteopathic correction is clinically effective in the complex treatment of patients with primary open-angle II A glaucoma.

In order to increase the pregnancy rate in the assisted reproductive technology, the selection of one embryo with the highest implantation potential it is very important. Time-lapse microscopy (TLM) is a tool for selecting quality embryos for transfer. This study aimed to assess the benefits of single-embryo transfer of autologous oocytes performed on day 5 of embryo incubation in a TLM-equipped system in IVF and ICSI programs. Single-embryo transfer following incubation in a TLM-equipped incubator was performed in 282 patients, who formed the main group; the control group consisted of 461 patients undergoing single-embryo transfer following a traditional culture and embryo selection procedure. We assessed the quality of transferred embryos, the rates of clinical pregnancy and delivery. The groups did not differ in the ratio of IVF and ICSI cycles, average age, and infertility factor. The proportion of excellent quality embryos for transfer was 77.0% in the main group and 65.1% in the control group (p = 0.001). In the subgroup with receiving eight and less oocytes we noted the tendency of receiving more quality embryos in the main group (р = 0.052). In the subgroup of nine and more oocytes the quality of the transferred embryos did not differ between two groups. The clinical pregnancy rate was 60.2% in the main group and 52.9% in the control group (p = 0.057). The delivery rate was 45.0% in the main group and 39.9% in the control group (p > 0.050).

Aim. To study the influence of deproteinized dialysate from blood of milk-fed calves on the type of exudative discharge and dynamics of inflammatory reaction after hernia repair with plastics of the anterior abdominal wall with hernioendoprosthesis of polypropylene. Materials and Methods. The study involved 59 patients being on stationary treatment in the surgical department of Kursk Regional Clinical Hospital. Patients were hospitalized for the herniation of small or medium dimension. The patients were divided to two groups: the main (n=30) and control (n=29) groups. After endoprosthetics, the patients of the control group were given complex conservative treatment. The patients of the main group, besides standard treatment, were administered deproteinized dialysate from blood of milk-fed calves intravenously in drips 10 ml + 200 ml of 0.9% sodium chloride solution within 7 days. For cytological examination and determination of the type of cytograms, the traumatic discharge was collected and analyzed using the method of M.F. Kamaev and M.A. Palthsev. Results. Cytomorphometric examination was conducted on the third, fifth and seventh day after endoprosthetics with the aim of studying dynamic changes. Determination of cell composition and also of its changes characteristic of each studied period, was necessary for obtaining further information characterizing inflammatory process in the region of placement of the endoprosthesis. After endoprosthetics in patients who were administered hemodialysate, the inflammatory reaction was less pronounced than in patients who did not receive the preparation. This was associated with a more dynamic change of stages of the inflammatory process. In patients of the main group who received deproteinized dialysate, regenerative type of inflammation first appeared on the fifth day and made 6.9%; by the seventh day the share of patients with the regenerative type rose to 17.5%, while in the patients of the control group no regeneration stage was observed in both periods. Conclusion. Analysis of the efficiency of influence of hemodialysate on the inflammatory reaction in plastics of the anterior abdominal wall with polypropylene endoprosthesis evidences faster course of all stages of inflammation and reduction of its intensity by 10%.
