The aim of the present study was to assess the functional and radiologic results of this method. MATERIAL AND METHODS This retrospective study was performed in 37 Tönnis grade II and III dysplastic hips of 30 patients. The mean age of the patients at operation was 12.4 months. The mean follow-up time was 24.5 months. Posteromedial limited surgery was applied when sufficient stable concentric reduction was not achieved by closed technique. No pre-operative traction was applied. Postoperatively, human position hip spica cast was applied for 3 months. Outcomes were evaluated regarding modified McKay functional results, acetabular index and presences of residual acetabular dysplasia or avascular necrosis. RESULTS Thirty-six hips had satisfactory and one hip had poor functional result. The mean pre-operative acetabular index was 34.5 degrees. It improved to 27.7 and 23.1 degrees at the postoperative 6th month and the last control X-Rays. The change in acetabular index was statistically significant (p<0.05). At the last control, 3 hips had findings of residual acetabular dysplasia and 2 hips had avascular necrosis. CONCLUSIONS Posteromedial limited surgery for developmental dysplasia of the hip is indicated when closed reduction remains insufficient and medial open articular reduction remains unnecessarily invasive.

One of the options is to use a long head of the biceps tendon (LHBT) autograft. This paper presents the fi rst clinical outcomes of the SCR of the shoulder joint using the LHBT autograft. MATERIAL AND METHODS It is a prospective non-randomised study in which 14 patients were included, namely 7 men and 7 women. The patients were evaluated using the pain VAS, UCLA (The University of California at Los Angeles) Shoulder Rating Scale and ASES (The American Shoulder and Elbow Surgeons) Shoulder Score. The minimum follow-up was 12 months after surgery. The measured values were analysed using the standard statistical methods. RESULTS From August 2020 to January 2022, a total of 14 SCR with biceps tendon autograph were performed at our department. The mean age of the patients was 62 years (40-72). The mean value of the UCLA Shoulder Score was 12.36 ± 2.92 points preoperatively, while after surgery the obtained values increased to the mean value of 28.86 ± 3.08 points. The ASES score was 25.48 ± 3.89 points preoperatively and 82.41 ± 7.95 points at one year after surgery. The preoperative mean VAS score was 6.14 ± 1.10 points and 1.36 ± 0.93 points at one year after surgery. The mean active shoulder fl exion measured preoperatively was 140 degrees, whereas at one year after surgery it was 171 degrees. The mean active abduction reached 123 degrees before surgery and 169 degrees after surgery. The mean active external rotation of the shoulder joint was 59 degrees preoperatively and 52 degrees postoperatively. The mean active external rotation at 90 degrees of abduction was 52 degrees preoperatively and 60 degrees postoperatively. Whereas the improvement as against the preoperative status measured by the UCLA, ASES and pain VAS was signifi cant, the differences in the range of motion were signifi cant in the case of active fl exion and abduction only. DISCUSSION Painful irreparable rotator cuff tear constitutes an indication for SCR. The reconstruction is performed using autografts, allografts and xenografts. In literature, several SCR surgical techniques using a long head of the biceps tendon have been presented. In most of these techniques the supraglenoid insertion of the LHBT was left intact. Our study showed a signifi - cant relief from problems and good functional outcomes at 1 year after surgery when the biceps tendon had been used. Similar results are reported also by other studies using the biceps tendon for SCR. When comparing this study and the other study we published earlier on SCR with xenografts, there is no signifi cant difference in the clinical outcomes between these two techniques. On the very contrary, they are slightly better in some parameters.

Eight different fi xation methods were applied to each fracture model. Displacement of the fracture models was measured under the translational and torsional forces. RESULTS In the transverse fracture model; the 6th method provided the best stability in internal rotation, external rotation, and extension loading. In varus 7th method, valgus 8th, and fl exion the 5th and 2nd methods had the best stability. In the lateral oblique fracture model; the 7th method had the best stability in all loading directions except fl exion and the 6th method had the best stability in fl exion and had acceptable values in all other directions except valgus and external rotation.

There are few studies that have tested the adequacy of the angle made with the glenoid and the height from the glenoid level of the repaired labral tissue, but the correlation with the clinical results is not clear. The aim of this study was to defi ne the correlation of the height and slope of the repaired labral tissue in the glenoid anterior with the clinical results. MATERIAL AND METHODS This prospective study included 20 patients who underwent an arthroscopic Bankart repair. To evaluate the labrum anatomy of the affected shoulder, 4 measurement parameters were defi ned as axial height (Ah), axial slope (As), oblique coronal height (Ch), and oblique coronal slope (Cs) on non-contrast T2 MRI. The measurements were taken preoperatively of the affected shoulder and at 1 year postoperatively of both the affected shoulder and the contralateral asymptomatic shoulder. The measured values were compared with each other and with the contralateral shoulder. Correlations of the anatomic values with the Constant-Murley scores recorded at 1, 3, 6, and 12 months postoperatively were examined with the Wilcoxon test. RESULTS The mean preoperative Constant score of the patients was 57.7 (32-77) and postoperative scores at 1, 3, 6, and 12 months were 63.6 (44-79), 77.8 (61-90), 89.6 (77-100), and 95.2 (79-100), respectively (p=0.001). There was a statistically signifi cant difference in the preoperative MRI measurements of the axial and oblique coronal plane labral height and slope values compared to the postoperative values and those of the asymptomatic contralateral shoulder (p< 0.05 for all). There was no statistically signifi cant difference between the labral height and slope values of both planes postoperatively compared to the asymptomatic contralateral shoulder (p= 0.776, p= 0.910, p= 0.132, p= 0.589, respectively).

Over the last decade, there has been a steep rise in the number of studies evaluating its effect, i.e. blood loss reduction in specific surgical procedures. The aim of our study was to evaluate the effect of tranexamic acid on reducing intraoperative blood loss, postoperative blood loss into the drain, total blood loss, transfusion requirements, and development of symptomatic wound hematoma in conventional single-level lumbar decompression and stabilization. MATERIAL AND METHODS The study included patients who had undergone a traditional open lumbar spine surgery in the form of single-level decompression and stabilisation. The patients were randomized into two groups. The study group received a 15 mg/kg dose of tranexamic acid intravenously during the induction of anaesthesia and then again 6 hours later. No tranexamic acid was administered to the control group. In all patients, intraoperative blood loss, postoperative blood loss into the drain, and therefore also total blood loss, transfusion requirements and potential development of a symptomatic postoperative wound hematoma requiring surgical evacuation were recorded. The data of the two groups were compared. RESULTS The cohort includes 162 patients, 81 in the study group and the same number in the control group. In the intraoperative blood loss assessment, no statistically significant difference between the two groups was observed; 430 (190-910) mL vs. 435 (200-900) mL. In case of post-operative drain blood loss, a statistically significantly lower volume was reported after the tranexamic acid administration; 405 (180-750) mL vs. 490 (210-820) mL. When evaluating the total blood loss, a statistically significant difference was also confirmed, namely in favour of the tranexamic acid; 860 (470-1410) mL vs. 910 (500- 1420) mL. The reduction of total blood loss did not result in a difference in the number of administered transfusions; transfusions were given to 4 patients in each group. A postoperative wound hematoma requiring surgical evacuation developed in 1 patient in the group with the tranexamic acid and in 4 patients in the control group, but the difference was not statistically significant with respect to the insufficient group size. No patient in our study experienced complications associated with tranexamic acid application. DISCUSSION The beneficial effect of tranexamic acid on reducing blood loss in lumbar spine surgeries has already been confirmed by numerous meta-analyses. The question remains in what types of procedures, at what dose and route of administration its effect is significant. To date, most of the studies have explored its effect in multi-level decompressions and stabilizations.

Furthermore, we also discuss the possible implications of late diagnosis of such condition. The patient was initially referred from the Emergency Department as a case of head contusion with a left upper limb paresis. Due to only minimal bony trauma visible on the initial spine CT scan, the neurological deficit was attributed to the cranial trauma.

The aim of this study was to investigate the effect and mechanism of miRNA-140-3p in bone mesenchymal stem cells (BMSCs)-derived exosomes under hypoxia on inflammatory articular chondrocytes. MATERIAL AND METHODS To simulate the pathological status of arthritis, rat chondrocytes were used to establish the osteoarthritis (OA) model by IL-1β (10 μg/ml) as a modulating in vitro, and exosomes were isolated by differential ultra-high speed centrifugation. The cell counting kit-8, wound healing and flow cytometry assays were utilized to assess proliferation, migration and apoptosis of chondrocytes, respectively. Lipogenic and chondrogenic differentiation of chondrocytes were detected by oil red O staining and toluidine blue staining individually. The expressions of miR-140-3p and chondrocyte-specific gene mRNA were investigated using qRT-PCR. Western blot was applied to assess chondrocyte associated proteins and BMSC-Exo surface protein markers, and immunohistochemistry was adopted to detect the staining of collagen I and II. RESULTS Under scanning electronic microscope, the shape of exosomes was almost round. Exosome treatment prominently impaired the inhibition of chondrocytes' proliferative and migrative ability by IL-1β. It was found hypoxia had a more marked impact on proliferation, expression of collagen II and apoptosis in OA chondrocytes than normoxia, as well as a stronger effect on weakening adipose differentiation and enhancing chondrogenic differentiation in inflammatory chondrocytes. Furthermore, incubation with BMSC-Exo overexpressing miR-140-3p can remarkably increase the survival rate and migration in inflammatory chondrocytes. In addition, overexpression of miR-140-3p was found to enhance the chondrogenic differentiation of inflammatory chondrocytes. Furthermore, we found that the healing effect of exosomes on inflammatory chondrocytes under hypoxic conditions was produced by a rise in miR-140-3p expression within them and that hypoxia-mediated upregulation of miR-140-3p expression occurred through HIF-1α.

Surgical treatment can be achieved using different techniques including proximal femoral varus derotation osteotomy (FVDRO), pelvic osteotomies, and open hip reduction (OHR). However, we claim that pathologies originating from extraarticular structures in the dislocated hip in CP can be reconstructed by extraarticular methods and OHR may not always be necessary. Therefore, this study aims to discuss the results of hip reconstruction with extraarticular intervention in patients with CP. MATERIAL AND METHODS In total, 141 hips (95 patients) were included in the study. All patients underwent FVDRO, either with or without a Dega osteotomy. Changes in the Acetabular Index (AI), Migration Index (MI), neck-shaft angle (NSA), and center-edge angle (CEA) were assessed on the preoperative, postoperative, and final follow-up anterior-posterior radiographs of the pelvis. RESULTS Median age was 8 years (range between 4-18 years). The average follow-up duration was 5 years (range between 2-9 years). Changes in AI, MI, NSA and CEA values were statistically significant for postop and follow-up periods when compared to preoperative values. Of the 141 operated hips, 8 (5.6%) hips required revision surgery due to redislocation/resubluxation detected at the follow-ups, and unilateral operation can be accepted as a risk factor for redislocation.
