Introduction Football and futsal were the main sports in the Malaysian Games. However, they were associated with a risk of injury. The purpose of the study was to analyse the incidence, circumstances, and characteristics of football and futsal injuries during the Malaysian Games of 2018. Materials and method During the tournament, 14 teams participated in men’s football, 12 teams in men’s futsal and 11 teams in women’s futsal. The biannual event involved athletes aged under 21 years. A medical report form used by FIFA Medical Assessment and Research Centre (F-Marc), was provided to the physiotherapists and team doctors of all the teams to report all injuries after each match. Results The response rate was 84.62% in football and 59.76% in futsal. A total of 48 injuries were reported from 26 football matches, equivalent to 64.64 injuries per 1000 match hours (95%CI 46.35 to 82.93). In futsal, a total of 48 injuries from 41 matches were reported, equivalent to 292.42 injuries per 1000 match hours (95% CI 209.7 to 375.14). The rate of injury in women futsal players was higher compared to men 358.21 versus 247.04 injuries per 1000 match hours (p=0.224). Futsal recorded higher injuries per 1000 match hours than football (p less then 0.001). Conclusion The rate of severe injury in futsal and football recorded in the study as compared to previous studies gave rise to serious concerns. Hence, there was an urgent need to pay more attention to injury prevention strategies. © 2020 Malaysian Orthopaedic Association (MOA). see more All Rights Reserved.Introduction Orthopaedic surgeons are significantly predisposed to musculoskeletal injury, and these injuries can have negative effects on surgeon function and patient outcomes. While this phenomenon has been studied in the non-Asian population of surgeons, no study has been carried out in the local or regional Asian setting. The aim of this study was to determine the prevalence, characteristics and associations of occupational injuries in orthopaedic surgeons and residents, and to assess its functional impact. Materials and Methods The Nordic Musculoskeletal Questionnaire was sent out to all orthopaedic consultants and residents at two institutions in Singapore, via an email link to an online survey. Separately, further questions on symptom description, severity and treatment were surveyed. Additional information like age, gender, height and weight were obtained as well. Results A total of 87.5% respondents have at least one injury. Neck symptoms (66.1%) were the most prevalent, and back symptoms had the highest median severity score (4.5/10). The 74.1% of these injuries were reported as directly attributable to work. Age was found to be associated with an increase in the total number of anatomical areas affected (p = 0.016). A seated operating position was associated with more severe back pain (p = 0.040). Conclusion There is a high prevalence of occupational injuries sustained in our population of orthopaedic surgeons. Neck symptoms, followed by back and wrist symptoms, were the predominant symptoms in our population. Targeted ergonomic interventions may be considered to prevent specific musculoskeletal injuries in our population of orthopaedic surgeons. © 2020 Malaysian Orthopaedic Association (MOA).

Material and Methods Retrospective review was done to the patients who received two-stage revisions with an antibiotic loaded cement-spacer for PJI of the hip between January 2010 to May 2015. We found 65 patients (65 hips) with positive culture findings. Eight patients were lost to follow-up and excluded from the study. Among the rest of the 57 patients, methicillin-resistant infection (MR Group) was found in 28 cases. We also evaluate the 29 other cases that caused by the other pathogen as control group. We compared all of the relevant medical records and the treatment outcomes between the two groups. Results The mean of follow-up period was 33.7 months in the methicillin-resistant group and 28.4 months in the control group (p = 0.27). The causal pathogens in the methicillin-resistant group were Methicillin-resistant Staphylococcus aureus (etic joint infection (PJI) of the hip. © 2020 Malaysian Orthopaedic Association (MOA).

We postulate that the peculiar anti-gravity movement of the FNE in the medial migration phenomenon stems from a ratcheting mechanism at the intramedullary nail-FNE interface, which should inadvertently produce unique wear patterns on the FNE that can be seen with high-powered microscopy. By examining the wear patterns on retrieved implants from patients with medial migration, our study aims to draw clinical correlations to the ratcheting mechanism hypothesis. Material and Methods Four FNEs were retrieved from revision surgeries of four patients with prior intramedullary nail fixation of their pertrochanteric hip fractures complicated by femoral head perforation. The FNEs were divided into two groups based on whether or not there was radiographic evidence of medial migration prior to the revisions. Wear patterns on the FNEs were then assessed using both scanning electron microscopy and light microscopy. Results Repetitive, linearly-arranged, regularly-spaced, unique transverse scratch marks were found only in the group with medial migration, corresponding to the specific segment of the FNE that passed through the intramedullary component of the PFNA during medial migration. These scratch marks were absent in the group without medial migration. Conclusion Our findings are in support of a ratcheting mechanism behind the medial migration phenomenon with repetitive toggling at the intramedullary nail-FNE interface and progressive propagation of the FNE against gravity. © 2020 Malaysian Orthopaedic Association (MOA).
