IMPLANT MOVEMENT ANALYSIS: A CT-BASED TECHNIQUE TO DIAGNOSE EARLY LOOSENING IN TOTAL HIP ARTHROPLASTY
Authors: Malchau H. 
Published: August 2024

The painful hip without obvious clinical or radiographic signs of complications is a well-known scenario for surgeons. The clinical tools we have access to currently lack a dynamic test for detecting early signs of motion between implant and bone.A new software, Sectra IMA, has a potential to facilitate diagnosis of early implant loosening by analysis of paired CT exams. In clinical practise the two scans are acquired by endpoint of a possible motion, “a provocation CT”, for example maximal external and internal rotation in a CT hip examination. 20 years of research by Olivecrona and Weidenhielm is the scientific background for the technique. Early results are presented by Sandberg et al 2022.To further validate and create clinical evidence more extensive clinical studies is needed. A proposal for a multicentric, global clinical study will be presented for further discussion.A new technique for diagnosis of acetabular cup loosening using computed tomography: preliminary experience in 10 patients.

When treating periprosthetic femur fractures (PPFFs) around total hip arthroplasty (THA)], determining implant fixation status preoperatively is important, since this guides treatment regarding ORIF versus revision. The purpose of this study was to determine the accuracy of preoperative implant fixation status determination utilizing plain films and CT scans.Twenty-four patients who underwent surgery for Vancouver B type PPFF were included in the study. Two joint surgeons and two traumatologists reviewed plain films alone and made a judgment on fixation status. They then reviewed CT scans and fixation status was reassessed. Concordance and discordance were recorded. Interobserver reliability was assessed using Kendall's W and intraobserver reliability was assessed using Cohen's Kappa. Ultimately, the “correct” response was determined by intraoperative findings, as we routinely test the component intraoperatively.Fifteen implants were found to be well-fixed (63%) and 9 were loose. Plain radiographs alone predicted correct fixation status in 53% of cases. When adding the CT data, the correct prediction only improved to 55%. Interestingly, concordance between plain radiographs and CT was noted in 82%. In concordant cases, the fixation status was found to be correct in 55% of cases. Of the 18% of cases with discordance, plain films were correct in 43% of cases, and the CT was correct in 57%. Interobserver reliability demonstrated poor agreement on plain films and moderate agreement on CT. Intraobserver reliability demonstrated moderate agreement on both plain films and CT.The ability to determine fixation status for proximal PPFFs around uncemented femoral components remains challenging. The addition of routine CT scanning did not significantly improve accuracy. We recommend careful intraoperative testing of femoral component fixation with surgical dislocation if necessary, and the surgeon should be prepared to revise or fix the fracture based on those findings.
FEMORAL NECK FRACTURE IN PATIENTS OLDER THAN 65 YEARS: COMPARISON OF RESULTS OF CANNULATED SCREW FIXATION VERSUS HEMIARTHROPLASTY
Authors: Cordero-Ampuero J. 
Published: August 2024

Debate continues about the best treatment for patients over 65 years with non-displaced subcapital hip fractures: internal fixation (IF) or hemiarthroplasty (HA). Surgical aggression, mortality, complications and recovery of walking ability after 1year have been compared between both treatments.Match-paired comparison of 2 retrospective cohorts. 220 patients with IF vs 220 receiving a cemented bipolar HA. Matching by age (82.6±7.16 years (65–99)), sex (74.5% women), year of intervention (2013–2021) and ASA scale (24.2% ASA II, 55.8% III, 20.0% IV).Age (p=0.172), sex (p=0.912), year of intervention (p=0.638) and ASA scale (p=0.726) showed no differences.Surgical aggression smaller in IF: Surgical time (p< 0,00001), haemoglobin/haematocrit loss (p <0,00001), need for transfusion (p<0,00008), in-hospital stay (p<0,00001).Mortality: higher in-hospital for hemiarthroplasties (12 deaths (5.5%) vs 1 (0.5%) (p=0.004) (RR=12, 1.5–91.5)). But no significant differences in 1-month (13 hemiarthroplasties, 6%, vs 9 osteosynthesis, 4.1%) and 1-year mortality (33 hemiarthroplasties, 15%, vs 35, 16%).Medical complications: no differences in urinary/respiratory infections, heart failure, ictus, myocardial infarction, digestive bleeding, pressure sores or pulmonary embolus (p=0.055).Surgical complications: no significant differences. HA: 6 intraoperative (2,7%) and 5 postoperative periprosthetic fractures (2,3%), 5 infections (2,3%), 10 dislocations (4,5%), 3 neurovascular injuries. IF: 10 acute fixation failures (4,5%), 2 infections (0,9%), 9 non-unions (4,1%), 16 ischemic necrosis (7,3%).Functional results: no significant differences; 12 patients in each group (5,5%) never walked again (p=1), 110 HA (50%) and 100 IF (45.5%) suffered worsening of previous walking ability (p=0.575), 98 HA (44%) and 108 IF patients (49%) returned to pre-fracture walking ability (p=0.339).Fixation with cannulated screws may be a better option for non-displaced femoral neck fractures because recovery of walking ability and complications are similar, while surgical aggression and in-hospital mortality are lower.

Published: August 2024

We aimed to examine outcomes between displaced femoral neck fracture (FNF) patients managed with total hip arthroplasty (THA) or hemi-arthroplasty (HA) via the anterolateral vs. posterior approach.We used data from the HEALTH trial (1,441 patients aged ≥50 with displaced FNFs randomized to THA vs. HA). We calculated each patient's propensity to undergo arthroplasty via the posterior approach, and matched them to 1 control (anterolateral approach) based on age (±5 years), and propensity score. We used Chi-Square/Fisher-Exact tests to compare dichotomous outcomes, and repeated measures ANOVA to examine differences in patient-reported outcomes (via the WOMAC subscores) from baseline to one-year postoperative. We used logistic regression to identify independent predictors of reoperation for instability in the posterior group.We identified 1,306 patients for this sub-analysis, 876 (67.1%) who received arthroplasty via an anterolateral approach, and 430 (32.9%) a posterior approach. The unadjusted rate of reoperation was significantly higher in the posterior group (10.7% vs. 7.1%).Following propensity score matching, we retained 790 patients (395 per group), with no between-group differences in patient, fracture, or implant characteristics. The matched cohort had a higher rate of comorbidities, and were less likely to be employed vs. the unmatched cohort. The rate of treatment for dislocation remained higher in the posterior group (6.1% vs. 2.0%) following matching.Repeated measures ANOVA revealed significantly better WOMAC pain, stiffness, function, and total scores in the posterior group. Between-group differences at 12-months were: pain - 0.59 (0.03–1.15); stiffness - 0.62 (0.35–0.87); function - 2.99 (0.12–5.86); total - 3.90 (0.24–7.56). We identified THA (vs. HA, odds ratio 2.05 [1.05–4.01]) as the only independent predictor of treatment for dislocation in the posterior group.Our analyses revealed that compromised patients with displaced FNFs who undergo arthroplasty via the posterior approach may report better symptoms at one-year vs. the anterolateral approach, despite a higher odds of reoperation for instability.

The purpose of our study is to examine the outcome of patients undergoing outpatient total hip arthroplasty with a BMI >35.Case-control matching on age, gender (46% female;54%male), and ASA (mean 2.8) with 51 outpatients BMI≥35 kg/m2 (mean of 40 (35–55)), mean age of 61 (38–78) matched to 51 outpatients BMI<35 kg/m2 (mean of 27 (17–34)) mean age 61 (33–78). Subsequently 47 inpatients BMI≥35 kg/m2 (mean of 40 (35–55)) mean age 62 (34–77) were matched outpatients BMI≥35 kg/m2. For each cohort, adverse events, readmission in 90 days, reoperations were recorded.Rate of adverse events was significantly higher in BMI ≥35: 15.69% verus 1.96% (p=0.039) with 5 reoperations in the BMI≥35 cohort vs 0 in the BMI<35 kg/m2 (p= 0.063). Readmissions did not differ between groups (p=0.125). No significant difference for all studied outcomes between the outpatient and inpatients cohorts with BMI≥35 kg/m2. The most complications requiring surgery/medical intervention (3B) were in the inpatient cohort of patients >35. The prevalence of Diabetes and Obstructive Sleep apnea was 21.6% and 29.4% for BMI>35 compared to 9.8% and 11.8%, for BMI <35, respectively.Severely obese patients have an overall higher rate of adverse events and reoperations however it should not be used a sole variable for deciding if the patient should be admitted or not.

Published: August 2024

AimsSagittal plane imbalance (SPI), or asymmetry between extension and flexion gaps, is an important issue in total knee arthroplasty (TKA). The purpose of this study was to compare SPI between kinematic alignment (KA), mechanical alignment (MA), and functional alignment (FA) strategies.MethodsIn 137 robotic-assisted TKAs, extension and flexion stressed gap laxities and bone resections were measured. The primary outcome was the proportion and magnitude of medial and lateral SPI (gap differential > 2.0 mm) for KA, MA, and FA. Secondary outcomes were the proportion of knees with severe (> 4.0 mm) SPI, and resection thicknesses for each technique, with KA as reference.ResultsFA showed significantly lower rates of medial and lateral SPI (2.9% and 2.2%) compared to KA (45.3%; p < 0.001, and 25.5%; p < 0.001) and compared to MA (52.6%; p < 0.001 and 29.9%; p < 0.001). There was no difference in medial and lateral SPI between KA and MA (p = 0.228 and p = 0.417, respectively). FA showed significantly lower rates of severe medial and lateral SPI (0 and 0%) compared to KA (8.0%; p < 0.001 and 7.3%; p = 0.001) and compared to MA (10.2%; p < 0.001 and 4.4%; p = 0.013). There was no difference in severe medial and lateral SPI between KA and MA (p = 0.527 and p = 0.307, respectively). MA resulted in thinner resections than KA in medial extension (mean difference (MD) 1.4 mm, SD 1.9; p < 0.001), medial flexion (MD 1.5 mm, SD 1.8; p < 0.001), and lateral extension (MD 1.1 mm, SD 1.9; p < 0.001). FA resulted in thinner resections than KA in medial extension (MD 1.6 mm, SD 1.4; p < 0.001) and lateral extension (MD 2.0 mm, SD 1.6; p < 0.001), but in thicker medial flexion resections (MD 0.8 mm, SD 1.4; p < 0.001).ConclusionMechanical and kinematic alignment (measured resection techniques) result in high rates of SPI. Pre-resection angular and translational adjustments with functional alignment, with typically smaller distal than posterior femoral resection, address this issue.Cite this article: Bone Jt Open 2024;5(8):681–687.

Published: August 2024

Purpose
We investigated the vertical implantation of a toric implantable collamer lens (ICL) and compared the rotational stability with that of horizontal implantation.

Methods
This matched comparative study retrospectively reviewed and analyzed data from patients who underwent ICL implantation from 2003–2022 by 1:1 matching vertical and horizontal (V and H toric groups, respectively) implantation patients according to preoperative astigmatism, spherical equivalent, sulcus-to-sulcus, anterior chamber depth, and ICL size. Visual acuity, manifest refraction, vaulting, and rotation were measured 3 months postoperatively.

Results
We included 646 eyes (323 each in the V and H toric groups). No statistically significant difference was observed between groups in postoperative visual acuity, refractive error, and astigmatism. Vaulting was lower in the V toric group. (P < 0.001). The mean lens rotation in the V toric group was less than that in the H toric group (1.11 ± 2.84° versus 3.02 ± 10.34°, P = 0.001). The proportion of eyes in the V and H toric groups showing ≥10° of rotation was 2.5% (8 eyes) and 6.5% (21 eyes), respectively (P = 0.014). Despite repositioning from rotation, three (0.9%) and eight (2.5%) eyes required removal owing to lens re-rotation in the V and H toric groups, respectively.

Conclusion
Toric ICL vertical implantation showed good rotational stability, and appropriate visual acuity correction results with relatively low vaulting. This procedure therefore presents an effective novel method that could replace horizontal toric ICL implantation.

Published: August 2024

Yogyakarta is one of the regions in Indonesia whose tourism sector has been affected by the Covid-19 pandemic. All tourism actors, especially onAlmost none of the MSME and informal sectors can escape the economic downturn due to the Covid-19 pandemic. They lost their income because tourist visits dropped by almost 100 percent. This is very worrying because it is known that Yogyakarta is one of the cities which is a tourist destination in Indonesia. The reopening of tourism objects after Covid-19 has become a momentum and turning point in promoting and developing the potential for halal tourism in DIY. The establishment of DIY as one of the National Priority Halal Destinations by the Ministry of Tourism in 2018 prompted the DIY government to encourage tourism actors such as restaurants and hotels to take part in halal certification from the Indonesian Ulema Council to ensure and increase consumer confidence in the halal tourism services provided.In general, the problems that are the object of discussion and are resolved within the scope of this research include identifying indicators that must be considered in developing tourism in DIY so that it complies with the Covid-19 Health protocol and the concept of Halal Tourism. In addition, it will also determine the characteristics of the Tourism Information System needed by Stakeholders in order to be able to support the implementation of the Covid-19 Health Protocol in the "New Normal" era and the implementation of Halal Tourism as a promising option. And finally in this research will also provide a proposal for a prototype / Information System Innovation that can be used and replicated by stakeholders in the Tourism sector, especially in DI

Idempotent vector spaces and their linear transformations
Authors: Johnston William , Wahl Rebecca G. 
Published: August 2024

Abstract
This article extends topics about linear algebra and operator theoretic linear transformations on complex vector spaces to those on bicomplex spaces. For example, Definition 3 for the first time defines algebraically idempotent vector spaces, which generalizes the standard definition of a vector space and which includes bicomplex vector spaces as a special case, along with its dimension and its basis in terms of a corresponding vectorial idempotent representation. The article also shows how an

bicomplex matrix’s idempotent representation leads to a bicomplex Jordan form and a description of its bicomplex invariant subspace lattice diagram. Similarly, in a new way, the article rigorously defines “bicomplex Banach and Hilbert” spaces, and then it expands, for the first time, the theory of compact operators on complex Banach spaces to those on bicomplex Banach spaces. In these ways, the article indicates that the idempotent representation extends complex linear algebra and operator theory in a surprisingly generalized and straightforward way to vector space results with bicomplex and multicomplex scalars.

Abstract

Objectives
The tobacco epidemic is more than just a health concern. It is a socioeconomic one with far-reaching effects. Smoking being the most common mode of tobacco use worldwide, has an impact on human life and well-being. Hence, this study aimed to seek the knowledge and awareness of adolescents about e-cigarettes and spread awareness about the harmful effects of vapig so as to reduce the ongoing rise in cigarette consumption among these individuals.

Methods
A questionnaire-based cross-sectional survey was conducted among 100 teenage children of urban schools in Delhi NCR of age group 14–17 years which collected information on teenage vaping practices, views about vaping, and their accessibility to vaping items. The data were analyzed using the Statistical Program for Social Sciences – SPSS version 25 through frequency and percent, graphs, Bar chart and Chi-squared test.

Results
A total 100 participants took part in the survey out of which of 59 were males and 41 were females. A significant proportion of the participants (94 %) possessed knowledge of e-cigarettes, and 14 % had actually used them at some point. Most of the participants were aware of the disposable variety of e-cigarettes and most of them thought that e-cigarettes were less addictive.

Conclusions
A significant portion of educated young adults who have never vaped are susceptible to using e-cigarettes in the future. It is also discovered that e-cigarettes are still available and being promoted in spite of the restrictions. In addition to good health education for minors, more stringent enforcement of current rules and monitoring could help prevent larger uptake in the future.
Effects of Cable Sheath on Deformation Coordination between the Sensing Fiber and Sand

Published: August 2024

Abstract
Distributed fiber optic sensing has been used for monitoring land subsidence, and accurate measurement of soil deformation relies on the coordination between the optical fiber and soil, also known as the deformation coordination between the optical fiber and soil (DCf–s). To investigate this issue, three types of optical cables with different sheath structures were embedded in triaxial specimens made of standard sand. The fiber strain was measured by optical frequency domain reflectometry. The axial deformation of the specimen was measured by a linear variable displacement transducer sensor. Each specimen was subjected to 12 loading and unloading cycles under varying axial stresses, confining pressures, and dry or wet conditions during the triaxial tests. Results shows that the Φ3 mm loose-tube optical cable has poor DCf–s with the strain not exceeding 15 με. Under a confining pressure of 200 kPa, 400 kPa, and 500 kPa, the DCf–s coefficients between the Φ3 mm tight-buffered optical cable and wet sand during loading are 0.266, 0.366, and 0.496, respectively. The DCf–s coefficients of the Φ5 mm tight-buffered optical cable under identical conditions are 0.186, 0.226, and 0.249. Overall, the Φ3 mm tight-buffered optical cable exhibits superior DCf–s compared with both the Φ5 mm tight-buffered optical cable and Φ3 mm loose-tube optical cable, indicating that the sheath structure is a crucial factor in determining the DCf–s. In addition, the DCf–s is also influenced by several other factors, including the number of loading–unloading cycles and the confining pressure in the soil.

This Clinical Report was revised. See https://doi.org/10.1542/peds.2023-061450.
This set of guidelines is designed to assist the pediatrician in caring for children with Marfan syndrome confirmed by clinical criteria. Although pediatricians usually first see children with Marfan syndrome during infancy, occasionally they will be called on to advise the pregnant woman who has been informed of the prenatal diagnosis of Marfan syndrome. Therefore, these guidelines offer advice for this situation as well.
