Newcastle approach for the treatment of supra-intercondylar fractures in children
The aim of this study is to evaluate the functional results of open reduction using the Newcastle approach and internal fixation for complex intra-articular distal humeral fractures in children through the report of cases. A retrospective case series of patients who underwent open reduction and internal fixation surgery because of a complex intra-articular distal humeral fracture using the Newcastle approach were reviewed. Minimum follow-up was 2 years. Demographic, clinical, and radiological data were analyzed. Also, Mayo Elbow Performance Score and four-point Likert scale were evaluated. 2 children were included in the final analysis. In both fractures, the approach was sufficient for accurate reduction and the functional outcome on both elbows was satisfactory. The Mayo elbow score was 95 points (excellent results) and the five-point Likert scale, both patients were very satisfied with the outcomes. In the radiographic study, no necrosis or secondary deformities were observed. Our study provides evidence that the Newcastle approach is an alternative to perform open reduction in those children supra-intercondylar fractures that cannot be reduced using a close reduction. To our knowledge, there is not previous paper that has reported the used of this approach in the treatment in this kind of fractures

Impact of subtrochanteric fractures in the geriatric population : better pre-fracture condition but poorer outcome than pertrochanteric fractures: evidence from the Spanish Hip Fracture Registry
Clinical management in orthogeriatric units and outcome indicators are similar for extracapsular fragility hip fractures, without discriminating between subtrochanteric and pertrochanteric fractures. Geriatric patients, 75 years or older, with subtrochanteric fractures have worse clinical and functional outcomes than those with pertrochanteric fractures. Retrospective observational study of data prospectively collected by the Spanish Hip Fracture Registry including patients 75 years or older, admitted for extracapsular hip fractures from January 2017 to June 2019. Demographic and baseline status, pre-operative, post-operative and 30-day follow-up data were included. A total of 13,939 patients with extracapsular hip fractures were registered: 12,199 (87.5%) pertrochanteric and 1740 (12.5%) subtrochanteric. At admission, patients with subtrochanteric fractures were younger (86.5 ± 5.8 versus 87.1 ± 5.6 years old), had better pre-fracture mobility (3.7 ± 2.7 versus 3.9 ± 2.8) (1-to-10 scale, 1 being independent) and were more likely to be living at home; those with pertrochanteric fractures had worse cognitive function (Pfeiffer 3.3 ± 3.3 versus 3.8 ± 3.5). The subtrochanteric fracture group showed worse post-fracture mobility (7.3 ± 2.7 versus 6.7 ± 2.7) and greater deterioration of mobility (3.7 ± 3.0 versus 2.9 ± 2.7). Among individuals living at home at baseline, those with subtrochanteric fractures were more likely to remain in an assisted facility at 30-day follow-up. In-hospital mortality during acute admission was higher for the subtrochanteric group (5.6% versus 4.5%) (p = 0.028). To our knowledge, this is the first paper highlighting the differences between these two fracture groups in the geriatric population. Subtrochanteric fractures in the older population are a different and worse entity, with greater morbimortality and functional decline than pertrochanteric fractures. Despite being younger and fitter at admission, older patients with subtrochanteric fractures have a higher risk of remaining non-weight bearing and undergoing re-operation and institutionalization. Orthogeriatric units should be aware of this and manage subtrochanteric fractures accordingly. Level of evidence: IV.

Influencia del diseño de alta flexión, con conservación del LCP, en el rango de movimiento tras la implantación de una prótesis total de rodilla
Els nous implants de genoll pretenen millorar la flexió màxima aconseguida amb els implants convencionals. El nostre estudi pretén demostrar que els pacients intervinguts quirúrgicament, per a la implantació d'una artroplàstia total de genoll d'alta flexió, són capaços d'aconseguir un balanç articular i una flexió màxima superior a l'aconseguida pels pacients tractats amb el model convencional. La flexió màxima post-operatòria, a l'any de la intervenció, va ser 13º major en el grup de pacients portadors d'un implant d'alta flexió, respecte al grup de pacients portadors d'un implant convencional.

Is it really advantageous to operate proximal femoral fractures within 48 h from diagnosis? – A multicentric retrospective study exploiting COVID pandemic-related delays in time to surgery
Objectives: Hip fractures in the elderly are common injuries that need timely surgical management. Since the beginning of the pandemic, patients with
a proximal femoral fracture (PFF) experienced a delay in time to surgery. The primary aim of this study was to evaluate a possible variation in mortality
in patients with PFF when comparing COVID-19 negative versus positive.
Methods: This is a multicentric and retrospective study including 3232 patients with PFF who underwent surgical management. The variables
taken into account were age, gender, the time elapsed between arrival at the emergency room and intervention, pre-operative American Society of
Anesthesiology score, pre-operative cardiovascular and respiratory disease, and 10-day/1-month/6-month mortality. For 2020, we had an additional
column, “COVID-19 swab positivity.”
Results: COVID-19 infection represents an independent mortality risk factor in patients with PFFs. Despite the delay in time-to-surgery occurring in
2020, no statistically significant variation in terms of mortality was detected. Within our sample, a statistically significant difference was not detected in
terms of mortality at 6 months, in patients operated within and beyond 48 h, as well as no difference between those operated within or after 12/24/72 h.
The mortality rate among subjects with PFF who tested positive for COVID-19 was statistically significantly higher than in patients with PFF who
tested. COVID-19 positivity resulted in an independent factor for mortality after PFF.
Conclusion: Despite the most recent literature recommending operating PFF patients as soon as possible, no significant difference in mortality was
found among patients operated before or after 48 h from diagnosis

National trends in total cholesterol obscure heterogeneous changes in HDL and non-HDL cholesterol and total-to-HDL cholesterol ratio : a pooled analysis of 458 population-based studies in Asian and Western countries
Background: Although high-density lipoprotein (HDL) and non-HDL cholesterol have opposite associations with coronary heart disease, multi-country reports of lipid trends only use total cholesterol (TC). Our aim was to compare trends in total, HDL and nonHDL cholesterol and the total-to-HDL cholesterol ratio in Asian and Western countries. Methods: We pooled 458 population-based studies with 82.1 million participants in 23 Asian and Western countries. We estimated changes in mean total, HDL and non-HDL cholesterol and mean total-to-HDL cholesterol ratio by country, sex and age group. Results: Since similar to 1980, mean TC increased in Asian countries. In Japan and South Korea, the TC rise was due to rising HDL cholesterol, which increased by up to 0.17 mmol/L per decade in Japanese women; in China, it was due to rising non-HDL cholesterol. TC declined in Western countries, except in Polish men. The decline was largest in Finland and Norway, at similar to 0.4 mmol/L per decade. The decline in TC in most Western countries was the net effect of an increase in HDL cholesterol and a decline in non-HDL cholesterol, with the HDL cholesterol increase largest in New Zealand and Switzerland. Mean total-to-HDL cholesterol ratio declined in Japan, South Korea and most Western countries, by as much as similar to 0.7 per decade in Swiss men (equivalent to similar to 26% decline in coronary heart disease risk per decade). The ratio increased in China. Conclusions: HDL cholesterol has risen and the total-to-HDL cholesterol ratio has declined in many Western countries, Japan and South Korea, with only a weak correlation with changes in TC or non-HDL cholesterol.Peer reviewe
Accelerated surgery versus standard care in hip fracture (HIP ATTACK): an international, randomised, controlled trial
Repositioning of the global epicentre of non-optimal cholesterol
High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe
Implementación de una unidad de trauma geriátrico
Introducció
L'any 1990 es van produir 1,6 milions de fractures de maluc a tot el món i s'estima que aquesta xifra augmentarà a 6 milions l'any 2050.
A la Unió Europea es produeixen 600.000 fractures de maluc a l'any, aproximadament, amb un cost global anual de 13.000 milions d'Euros.
La incidència a Espanya és de 517 casos per cada 100.000 habitants i per any. L'edat mitjana de 82 anys i un 78% dels pacients són de sexe femení.
Els objectius del tractament de la fractura de maluc són preservar la vida i aconseguir una recuperació funcional que permeti el pacient integrar-se de nou en el seu medi habitual.
Però, en aquests pacients, la taxa de mortalitat s'eleva durant el primer any d'un 8,4% a un 36%. A l'any de la fractura el 50% presenten dificultats per caminar, el 38-39% presenten dificultat per fer transferències i el 17-19% presenten dificultats per a l’higiene.
Fins a un 90% dels pacients presenten múltiples comorbiditats, entre les quals la malaltia pulmonar obstructiva crònica, la demència, la hipertensió arterial, la patologia cardíaca isquèmica i la diabetis són les més comunes.
Les característiques d'aquests pacients, ancians i amb múltiples comorbiditats, va fer sorgir la idea de proporcionar-los una atenció compartida entre cirurgians ortopèdics i geriatres. Aquesta idea inicial ha evolucionat a la tendència actual d'implementar unitats de ortogeriatria que integrin un tractament multidisciplinari. En aquest model a geriatres i traumatòlegs se sumen també anestesistes, rehabilitadors, fisioterapeutes, infermeres i nutricionistes, entre d'altres.
Objectius
L'objectiu principal d'aquesta tesi doctoral és determinar la demora per a intervenció quirúrgica dels pacients amb fractura de fèmur proximal després de la implementació d'una unitat de ortogeriatria.
Els objectius secundaris són determinar el temps d'estada hospitalària, la mortalitat intrahospitalària i als 30 dies, i els reingressos que es produeixen per complicacions mèdiques i traumatològiques.
Material i mètodes
Durant l'any 2013 (juny-desembre), 2014 i 2015, van ingressar al nostre servei 534 fractures de maluc, de manera consecutiva. Mentre que en els anys 2011, 2012 i 2013 (gener-maig), quan encara no existia la Unitat de Traumatologia Geriàtrica (UTG) van ingressar 501.
Les dades recollides prospectivament en el segon període, després de la implementació de la UTG, han estat comparats amb les dades dels pacients que van ingressar en el primer període.
Resultats
La demora mitjana per a ser intervingut quirúrgicament prèviament a la implementació de la UTG va ser de 2,27 dies (DE = 2,35), mentre que posteriorment va ser de 1,84 (DE = 1,73). (P = 0,0004).
L'estada mitjana prèviament a la implementació de la UTG va ser de 11,39 dies (DE = 9,05), mentre que posteriorment va ser de 10,08 (DE = 5,43). (P = 0,0024).
La mortalitat en els primers 30 dies després de la fractura de maluc, prèviament a la implementació de la UTG va ser del 7,7%, mentre que posteriorment va ser de l'4,8%. (P = 0,027).
Conclusió
La implementació d'una unitat de ortogeriatria, per al tractament dels pacients amb fractura de fèmur proximal, que inclou un conjunt de mesures entre les que destaquen la introducció de circuits ràpids de tractament, tractament multidisciplinari integrat i protocols de rehabilitació primerenca postoperatòria, ha permès disminuir de 2,27-1,84 dies el temps de demora mitjà per ser intervingut quirúrgicament després de l'ingrés.
El temps d'estada hospitalària s'ha reduït en un temps mitjà d'un dia.
La mortalitat dels pacients als 30 dies s'ha reduït en un 2,9%.

In 1990, there were 1.6 million hip fractures worldwide. This number is expected to reach 6 million by 2050.
In the European Union, osteoporosis causes approximately 600.000 hip fractures per year. The annual estimated economic burden for healthcare systems is 13.000 million Euros.
The incidence of hip fractures in Spain is 517 cases per 100.000 inhabitants and year. The average age is 82 years and 78% are women.
The goal of hip fracture treatment is to return the patient to preoperative levels of function, facilitating return to pre-fracture residence and supporting long-term wellbeing.
Mortality rates in hip fracture patients rise from 8.4 to 36% in the first year after surgery. One year after the fracture, 50% have difficulties in walking, 38-39% are not able to transfer from a bed to a chair and 17-19% require aids for bathing and grooming.
Up to 90% of patients have several comorbidities. Commonly, these include chronic obstructive pulmonary disease, dementia, high blood pressure, ischemic heart disease, and diabetes.
Elderly patients with several comorbidities could benefit from shared care approaches provided by orthopedic surgeons and geriatricians. This cooperation has triggered the current trend of implementing orthogeriatric units that integrate multidisciplinary teams. In this model, several disciplines, besides surgeons and geriatricians, are involved in the care of the patients including anesthesiologists, physical therapists, nurses, and nutritionists.
Objectives
The main objective of this study is to determine the delay for surgical intervention of patients with proximal femur fracture after the implementation of an orthogeriatric unit.
Secondary objectives are to determine the length of hospital stay, in-hospital and 30-day mortality, and readmissions resulting from medical and trauma complications.
Material and methods
During 2013 (June-December), 2014, and 2015, 534 consecutive hip fractures were treated in our hospital. While in 2011, 2012, and 2013 (January-May), before the orthogeriatric unit (OGU) was created, 501 hip fractures were treated.
Data collected prospectively in the second period, after the implementation of the OGU, have been compared with the first period data.
Results
The mean delay to undergo surgery before the implementation of the OGU was 2.27 days (SD = 2.35), compared to 1.84 (SD = 1.73). (p = 0.0004) for the second period.
The average in-hospital stay before the implementation of the OGU was 11.39 days (SD = 9.05), compared to 10.08 (SD = 5.43). (p = 0.0024) after the orthogeriatric model of care was established.
30-day mortality rate after hip fracture, before OGU implementation, was 7.7%, and 4.8% afterward. (p = 0.027).
Conclusion
The implementation of an orthogeriatric unit for the treatment of patients with a hip fracture which requires a series of measures including the introduction of fast treatment circuits, integrated multidisciplinary treatment, and early postoperative rehabilitation protocols, has allowed a decrease from 2.27 to 1.84 days in the average time to surgery after admission.
The length of hospital stay was reduced by an average time of one day.
30-day mortality was reduced by 2.9%.
Readmissions for medical or surgical complications did not increase.Universitat Autònoma de Barcelona. Programa de Doctorat en Cirurgia i Ciències Morfològique
