This study aims to compare the results of internal fixation with dynamic hip screw (DHS)/antirotation screw and conventional cannulated screw (CS) for femoral neck fracture. This retrospective study included a total of 78 patients (57 males, 21 females) with collum femoris fractures treated with internal fixation between January 2015 and January 2019. Group 1 comprised 41 patients with a mean age of 45.7 years (range, 19 to 62 years) treated with DHSs/antirotation screws, while group 2 comprised 37 patients with a mean age of 41.9 years (range, 17 to 75 years) treated with CSs. The patients were evaluated for union, avascular necrosis (AVN), femoral neck shortness, operation time, duration of fluoroscopy exposure, and functional outcomes. Age, gender, and Garden classification stages were similar in both groups. No significant difference was found between the groups in respect of AVN and non-union rates. The non-union rate was 12.2% in group 1 and 21.6% in group 2 (p>0.05). The duration of fluoroscopy exposure was statistically significantly higher in group 2 (p=0.001) and the operation time was statistically significantly longer in group 1 (p=0.001). In group 2, femoral neck shortness stature was significantly higher (p=0.007). At the final follow-up examination, the Harris hip score was statistically significantly higher in group 1 (p=0.04). Dynamic hip screw/antirotation screw was a more relevant treatment method for transcervical femoral neck fractures compared to CS with more favorable functional outcomes and less fluoroscopy exposure.

Background: Distal chevron osteotomy (DCO) is commonly performed in hallux valgus surgery. The fixation of the osteotomy is provided by various implants. The usage of biodegradable implants such as magnesium is gradually increasing due to the advantages they provide. In this study, we aimed to compare the fixation of DCO with magnesium or titanium screw biomechanically. Methods: Twenty sawbones were used. The samples were divided into two equal groups, including ten sawbones for fixation with single headless titanium (group-1) or magnesium screw (group-2). DCO and screw fixations were performed on all samples using the same technique. Biomechanical testing was applied to five samples in each group in cantilever and the other five in a physiological configuration using a computer connected to the electromechanical test machine. The obtained data were evaluated using the Shapiro–Wilk test, Student’s t-test and Mann–Whitney U test on the IBM® SPSS (Statistical Package for the Social Sciences) V22.0 software. Significance was accepted at the p < 0.05 level. Results: There was no statistically significant difference between the magnesium screw and the titanium screw in terms of maximum force, maximum displacement and stiffness measurements in cantilever and physiological loadings (p > 0.05 for all). Conclusion: This study found no significant difference in biomechanical stability between the magnesium and titanium screws in DCO fixation on sawbones. Further studies with real bones are needed.
A quality-control Internet-based study using recognized quality scoring systems. The aim of the study is to evaluate the quality, content and readability of online information on kyphosis. The 3 most frequently used search engines were identified and a search for “Kyphosis” was made in each. The 2 reviewers categorized their Web-sites by type, and the quality of each was assessed using well-known scoring systems, including the DISCERN score, JAMA benchmark, GQS, and the kyphosis specific content score. The Flesch-Kincaid grade level (FKGL) was used to assess the readability. The quality of the information was also evaluated according to the presence and absence of the HONcode. Sixty unique Web sites were identified and analyzed. The distribution of the categories was 33 (55%) medical, 22 (36.7%) academic, 2 (3.3%) non-physician, 2 (3.3%) commercial and 1 (1.7%) physician. There wasn’t statistically significant difference between the sources in terms of DISCERN, JAMA, GQS and KSC scores (P > 0.05). However, a review of the FKGL scores revealed that the academic-based websites’ FKGL score was significantly higher than the medical-based websites (P: 0.007). Also there wasn’t statistically significant difference among the DISCERN, JAMA, GQS, KSC, FKRS and FKGL scores of the web-sites according to the HON code’s presence (P > 0.05). Information about kyphosis on the Internet is of limited quality and low information value. The readability of the online information in our results showed a significantly higher reading level than the sixth grade level recommended by the AMA and NIH.
Objective: To assess the predictive value of systemic inflammatory markers for postoperative complications in older adults undergoing posterior spinal instrumentation for either lumbar spinal stenosis (LSS) or osteoporotic vertebral fractures (OVFs). This study design as a retrospective observational study. Methods: Fifty-four patients aged ≥ 55 years who underwent posterior spinal instrumentation between 2020 and 2023 were retrospectively analyzed. Patients were grouped into LSS (n = 27) and OVF (n = 27) cohorts. Preoperative, early postoperative, and 6-month follow-up systemic inflammatory marker levels, including the Systemic Inflammatory Response Index (SIRI), Systemic Immune-Inflammation Index (SII), Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Monocyte-to-Lymphocyte Ratio (MLR), were recorded. The primary outcome was the occurrence of postoperative infectious complications. ROC curve analysis was conducted to evaluate the discriminatory power of each marker. Results: SIRI values were significantly higher in the OVF group than in the LSS group at all time points (p < 0.05). Postoperative complications occurred in 7.4% of patients, equally distributed between groups. ROC analysis showed that preoperative SIRI had the highest predictive value (AUC = 0.743), with a cutoff value of 2.69 yielding 100% sensitivity and 65.3% specificity. Other indices showed poor predictive accuracy (AUC < 0.70). Conclusions: Preoperative SIRI is a promising, easily obtainable biomarker for identifying older patients at higher risk of postoperative complications following posterior spinal instrumentation. Its implementation may improve preoperative risk stratification in spine surgery.
Purpose: It is known that the incidence of paediatric orthopaedic trauma peaks in the summer months as a result of increased and uncontrolled physical activity. The aim of this study was to review the experience of a single centre with paediatric orthopaedic traumas and determine the relationship between the severity and the variations in the incidence of traumas in relation to the seasons and temperatures during the study period. Materials and Methods: A single institutional review of the historical data of all patients aged 0–16 years who presented for orthopaedic trauma between January 2018 and December 2020 in the emergency department of Level 1 tertiary orthopaedic trauma centre was conducted. 65,182 paediatric orthopaedic trauma cases had been retrieved from the hospital data base during the 3 -year study period. We classified the traumas according to the variants of the patients’ and by holidays, seasons, school days and weekends, months and in which part of the body it occurred. Results: After excluding the summer vacation, 77% of paediatric orthopaedic trauma patients attended to the hospital on weekdays and 23% on weekends. While it was observed that hot weather had a statistically positive effect on trauma attendance, rainy weather had an negative effect ( p < 0.05). Trauma attendances were found to be statistically higher in summer months, except for injuries that may occur with indoor activities such as metacarpal fracture, phalanx fracture and pulled elbow ( p < 0.05). Conclusion: Orthopaedic trauma at a Level 1 tertiary health care trauma center do vary significantly with the weather and are highest in the summer season. Therefore, it should focus more attention on preventive strategies for paediatric trauma in the summer season.
