RESUMO
BACKGROUND: The popularity of uncemented stems in revision total hip arthroplasty (THA) has increased in the last decade. AIM: To assess the outcomes of both cemented and uncemented stems after mid-term follow up. METHODS: This study was performed following both the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement and the Cochrane Handbook for systematic reviews and meta-analysis guidelines. Articles were chosen irrespective of country of origin or language utilized for the article full texts. This paper included studies that reviewed revision THA for both cemented or uncemented long stems. RESULTS: Three eligible studies were included in the meta-analysis. Analysis was conducted by using Review Manager version 5.3. We computed the risk ratio as a measure of the treatment effect, taking into account heterogeneity. We used random-effect models. There were no significant differences found for intraoperative periprosthetic fractures [risk ratio (RR) = 1.25; 95% confidence interval (CI): 0.29-5.32; P = 0.76], aseptic loosening (RR = 2.15, 95%CI: 0.81-5.70; P = 0.13), dislocation rate (RR = 0.50; 95%CI: 0.10-2.47; P = 0.39), or infection rate (RR = 0.99, 95%CI: 0.82-1.19; P = 0.89), between the uncemented and the cemented long stems for revision THA after mid-term follow-up. CONCLUSION: This study has evaluated the mid-term outcomes of both cemented and uncemented stems at first-time revision THA. In summary, there were no significant differences in the dislocation rate, aseptic loosening, intraoperative periprosthetic fracture and infection rate between the two cohorts.
RESUMO
Background and objective Slipped upper femoral epiphysis (SUFE) is one of the most common hip pathologies in adolescents and pre-adolescents, the diagnosis of which is often missed due to delayed presentations. In this study, we aimed to conduct a retrospective analysis of SUFE cases treated in the hospital during the 15-year period from 2003 to 2018 and examine its bilateral presentation and the need for prophylactic pinning on the unaffected side. Methods This retrospective cohort study involved cases that were treated from 2003 to 2018. The case details were retrieved from the medical records department. Records older than 15 years were excluded owing to their inaccuracy, and 26 cases of SUFE were included in the final analysis. Each case was subjected to physical and radiological examinations of the symptomatic and asymptomatic hips. IBM SPSS Statistics v23 (IBM Corp., Armonk, NY) was used for data analysis. Results In this study, six of the 26 patients had bilateral SUFE and required subsequent surgical pinning. The duration of surgical interventions ranged from two to 22 months, while the mean intervention duration was 10.3 months. Among the cases, 61.5% (p<0.05) were idiopathic in nature upon documentation. However, 19% (p<0.05) of the cases were shown to be associated with an underlying condition or prior symptoms of the condition, whereas 7.6% (p<0.05) had an increased basal metabolic index; 11% (p<0.05) of the cases had an inherited family history of SUFE. A comparison between males and females showed a slightly higher frequency of complications in males (n=14) than in females (n=12) (p=0.556). The age of the patients at the presentation ranged between and 10-15 years, with an average age of 12.5 years. Conclusion Based on our findings, males were affected more than females and most of the cases were idiopathic. There is no significant evidence to support the need for prophylactic pinning of the unaffected hip. We recommend prospective studies with a larger sample of patients to gain more insight into the topic.
RESUMO
Introduction Virtual learning has become the preferred modality for health education during and after the coronavirus disease 2019 (COVID-19) pandemic. Peer learning is gaining a lot of significance lately and has been successfully tested in various settings. We combined virtual delivery of health education with peer-assisted learning and evaluated the effectiveness using peer-generated feedback and tested the effectiveness of the model for different cohorts. Methods We performed this study as part of a formal educational course on Health Professions Education. The educators were volunteers from different informal multi-disciplinary groups, working in varied healthcare settings, globally. This involved eight teaching sessions which were delivered virtually and the feedback was recorded as responses to six items (questions), which the learners graded on the Likert scale. The average for each item and the larger domains was then calculated and analyzed. Results The feedback was provided by all the participants (53/53). In the feedback received item-wise, the best average rating was for legibility of the slides (4.8). The least rating was for adequate checking and assessment of prior knowledge (4.2). In terms of the broader domains, the best feedback was for the teaching material (4.6) and the lowest was for the planning of the sessions (4.4). Overall, the ratings for the domains and the items were above 3 on a scale of 1-5. Conclusions Virtual delivery of healthcare education, facilitated by peer-assisted learning, is an effective model for health education when delivered for a small group, as evidenced by the overall peer feedback. This model can be tested for larger cohorts in the future.
