RESUMO

Aims: Paediatric fractures are highly prevalent and are most often treated with plaster. The application and removal of plaster is often an anxiety-inducing experience for children. Decreasing the anxiety level may improve the patients' satisfaction and the quality of healthcare. Virtual reality (VR) has proven to effectively distract children and reduce their anxiety in other clinical settings, and it seems to have a similar effect during plaster treatment. This study aims to further investigate the effect of VR on the anxiety level of children with fractures who undergo plaster removal or replacement in the plaster room. Methods: A randomized controlled trial was conducted. A total of 255 patients were included, aged five to 17 years, who needed plaster treatment for a fracture of the upper or lower limb. Randomization was stratified for age (five to 11 and 12 to 17 years). The intervention group was distracted with VR goggles and headphones during the plaster treatment, whereas the control group received standard care. As the primary outcome, the post-procedural level of anxiety was measured with the Child Fear Scale (CFS). Secondary outcomes included the children's anxiety reduction (difference between CFS after and CFS before plaster procedure), numerical rating scale (NRS) pain, NRS satisfaction of the children and accompanying parents/guardians, and the children's heart rates during the procedure. An independent-samples t-test and Mann-Whitney U test (depending on the data distribution) were used to analyze the data. Results: The post-procedural CFS was significantly lower (p < 0.001) in the intervention group (proportion of children with no anxiety = 78.6%) than in the control group (56.8%). The anxiety reduction, NRS pain and satisfaction scores, and heart rates showed no significant differences between the control group and the intervention group. Subanalyses showed an increased effect of VR on anxiety levels in young patients, females, upper limb fractures, and those who had had previous plaster treatment. Conclusion: VR effectively reduces the anxiety levels of children in the plaster room, especially in young girls. No statistically significant effects were seen regarding pain, heart rate, or satisfaction scores.

RESUMO

BACKGROUND: Almost 50% of the patients requiring knee replacement are suitable for medial unicompartmental knee arthroplasty (UKA). However, national registries have shown a use far below 50%. AIM: The aim of this study was to identify the factors that could influence the use of UKA. METHODS: A questionnaire was conducted among practicing knee surgeons of the Dutch Orthopedic Association. The questionnaire was classified into three domains: surgeon, patient selection, and professional opinion. Associations between the domains and UKA volume and contra-indications were tested using Pearson's chi-square tests. RESULTS: Of the 113 included respondents, 40% had no hands-on exposure during residency. Frequently reported contra-indications were obesity (68%), lateral osteophytes (21%), chondrocalcinosis (20%), and age (20%). Medial partial thickness lesions were considered a contra-indication by 49% and lateral joint space narrowing by 61% of the respondents. Respondents perceived UKA to outperform total knee arthroplasty regarding all outcomes, except survival (1.8% versus 42%). The reported barriers for UKA use were insufficient experience (20%), high revision rates (20%), and low hospital volume (16%), whereas 60% did not experience any at all. Hands-on UKA exposure during residency was associated with an increased use of correct indications. Furthermore, the use of correct indications was associated with an increased UKA volume. CONCLUSION: We showed a low UKA exposure during residency and considerable variations in contra-indications. These factors may contribute to an underuse of UKA. Improved UKA training could lead to increased experience and better patient selection among surgeons and consequently a higher use of medial UKA.

RESUMO

BACKGROUND: It has been suggested that hypertrophy of the radial tuberosity may result in impingement leading to either a lesion of the distal biceps tendon or rotational impairment. Two previous studies on hypertrophy of the radial tuberosity had contradictory results and did not examine the distance between the radius and ulna: the radioulnar window. Therefore, this comparative cohort study aimed to investigate the radioulnar window in healthy subjects and compare it with that in subjects with either nontraumatic-onset rotational impairment of the forearm or nontraumatic-onset distal biceps tendon ruptures with rotational impairment of the forearm by use of dynamic 3-dimensional computed tomography measurements to attain a comprehensive understanding of the underlying etiology of distal biceps tendon ruptures. We hypothesized that a smaller radioulnar window would increase the risk of having a nontraumatic-onset distal biceps tendon rupture and/or rotational impairment compared with healthy individuals. METHODS: This study measured the distance between the radius and ulna at the level of the radial tuberosity using entire-forearm computed tomography scans of 15 patients at the Amphia Hospital between 2019 and 2022. Measurements of healthy subjects were compared with those of subjects who had nontraumatic-onset rotational impairment of the forearm and subjects who had a nontraumatic-onset distal biceps tendon rupture with rotational impairment of the forearm. The Wilcoxon signed rank test was used for individual comparisons, and the Mann-Whitney U test was used for group comparisons. RESULTS: A significant difference was found between the radioulnar window in the forearms of the subjects with a distal biceps tendon rupture (mean, 1.6 mm; standard deviation 0.2 mm) and the radioulnar window in the forearms of the healthy subjects (mean, 4.8 mm; standard deviation, 1.4 mm; P = .018). A trend toward smaller radioulnar windows in the rotational impairment groups was also observed, although it was not significant (P > .05). CONCLUSIONS: The radioulnar window in the forearms of the subjects with a distal biceps tendon rupture with rotational impairment was significantly smaller than that in the forearms of the healthy subjects. Therefore, patients with a smaller radioulnar window have a higher risk of rupturing the distal biceps tendon. Nontraumatic-onset rotational impairment of the forearm may also be caused by a similar mechanism. Future studies are needed to further evaluate these findings.

RESUMO

BACKGROUND: To reduce the risk of dislocation, larger head size can be used in total hip arthroplasty (THA). However, larger head size leads to thinner acetabular liners. With conventional polyethylene, thickness of >8 mm has been advocated to reduce stress and wear rate of the polyethylene. Modern polyethylene has become more wear-resistant. In this study, we investigated if the thickness of sequentially cross-linked polyethylene (XLPE) liners is associated with failure of THA in the medium term. PATIENTS AND METHODS: 3654 THAs were included (2009-2016), in which THA was performed with a XLPE liner in combination with a 36-mm femoral head. Patient and surgical characteristics were collected. We compared implant survival of THA with thin liners (<7.9 mm) and thick liners (⩾7.9 mm) with a Kaplan Meier survival analysis at 5 years, median follow-up and 10 years of follow-up with and point aseptic loosening and performed a multivariate analysis to estimate hazard ratios (HR). RESULTS: Median follow-up was 7.7 years (IQR 5.6-9.8). In total, 179 revision procedures were performed, where 82 revisions (46%) were performed for aseptic loosening. The survival rate at 5 years, median and 10 years of follow-up showed no statistically significant difference in implant survival. The survival rate at 10 years follow-up was for thin liners 97.1% (95% CI, 96.3-97.9) and for thick liners 98.2% (95% CI, 97.4-99.0) in the aseptic loosening group (chi-square 2.55; p = 0.11).The adjusted HR for thick liners (⩾7.9 mm) was 0.65 (95% CI, 0.38-1.08) compared with the thin liners (<7.9 mm), which was not significantly different. CONCLUSIONS: From this single-centre retrospective study it appears that thinner polyethylene liners are well tolerated when using second-generation highly cross-linked polyethylene. Thickness of the XLPE liners did not influence the risk of aseptic loosening of the implants in the medium term.

RESUMO

BACKGROUND: Despite the established advantages of partial knee replacements (PKR), their usage remains limited. We investigated the effect of hospital knee arthroplasty (KA) volume and the availability of a frequently used PKR by the total KA supplier on the use of PKRs in a hospital. METHODS: A total of 190,204 total knee replacements (TKR) and 18,134 PKRs were identified in the Dutch Arthroplasty Register (LROI) from 2007 to 2016. For each hospital we determined the annual absolute KA volume (TKR+PKR) into quartiles (<103, 103-197, 197-292, >292 knee replacements/year), and determined whether the TKR supplier provided a frequently used PKR. Hospitals were divided in routine PKR users (≥13 PKRs/year) or occasional/non PKR users (<13 PKRs/year). Based on these parameters, the effect of total KA volume and supplier on PKR usage was investigated, using chi-square tests. Logistic regression analysis was performed to evaluate the influence of the combination of these factors. RESULTS: In the lowest volume group, around 15% of the hospitals used PKRs, compared to 75% in the highest volume group. Having a TKR supplier that also provides a frequently used PKR resulted in a higher likelihood of performing PKR, especially in low volume hospitals. CONCLUSIONS: Hospitals' total KA volume and the availability of a frequently used PKR appear to influence the use of PKR.

RESUMO

BACKGROUND: Paediatric fractures are highly prevalent and are most often treated with plaster. The removal of plaster is often an anxious experience for children. Virtual reality (VR) has proven to effectively distract children and reduce their anxiety in other clinical settings. This study aims to investigate the effect of VR on the anxiety level of children with fractures that undergo plaster removal or replacement in the plaster room. METHODS: This study is designed as a randomised controlled trial (RCT). The sample size is 270 patients, aged 5 to 17 years, with a fracture of the upper or lower extremity treated with plaster. The intervention group will be distracted with VR goggles and headphones during the replacement or removal of the plaster, whereas the control group will receive standard care. As a primary outcome, the level of anxiety will be measured with the Child Fear Scale (CFS). Secondary outcomes include anxiety reduction (difference between CFS after and CFS before plaster procedure) and Numeric Rating Scales (NRS) pain and satisfaction. Additionally, the children's fastest heart rate during the procedure will be recorded. An unpaired samples t-test or a Mann-Whitney U test (depending on the data distribution) will be used to analyse the data. DISCUSSION: When completed, this trial will provide evidence on the potential role of VR in children with fractures treated with plaster. The purpose is to increase the quality of healthcare by decreasing anxiety and possibly pain perception of children during a plaster procedure. TRIAL REGISTRATION: Netherlands Trial Register NL9065 . Registered on 27 November 2020.
