ABSTRACT The rhizobia found in Fabaceae plants of the Caatinga may have potential as fodder in the semiarid region, thus increasing the availability of feed for animal production in this region. This study aimed to characterize the morphophysiology of rhizobia strains of the forage species Mimosa tenuiflora (Jurema preta), Macroptilium atropurpureum (Siratro), and Desmanthus pernambucanus (Jureminha). The soil used as the substrate was collected at specific locations in the municipalities of Sertânia, Arcoverde, and São Bento do Una, state of Pernambuco. The characterization of rhizobial colonies included growth period, diameter, elevation, transparency, exopolysaccharides production, and color. In addition, salinity, temperature, and pH tolerance tests of the native rhizobia were conducted. Evaluation of cultures showed that the isolates formed colonies with flat elevation, moderate production of exopolysaccharides, coloration varying from cream to white, and a smooth surface. Physiological tests of abiotic stress resistance showed that the native species isolated from M. tenuiflora were more resistant when grown in soils from the municipality of Sertânia and isolates from M. atropurpureum and D. pernambucanus had high resistance to high temperatures, regardless of place of farming. It can be concluded that native rhizobia from the Semiarid region of Pernambuco show resistance to stress caused by high temperatures, salinity variation, and pH. These characteristics are influenced by soil and the botanical species in symbiosis with the rhizobia.

ABSTRACT Watermelon (Citrullus lanatus) belongs to the plant family Cucurbitaceae. It is cultivated in many regions of Brazil, particularly in rainfed areas; thus, it is subject to the problems arising from irregular rainfall. Hydrogel is a soil conditioner used to retain and provide water to plants for long periods of time. Therefore, incorporating hydrogel into the soil should increase water availability for watermelon cultivation, and may be an alternative method to reduce the risk of water deficit. This study evaluated the effect of different concentrations of hydrogel on the initial growth of watermelon cv. 'Crimson Sweet' under different shading conditions. The experiment was carried out in a greenhouse with completely randomized design with a 4×3 factorial scheme. The treatments consisted of four hydrogel doses (0.0; 1.5; 3.0; and 6.0 g L-1 substrate), three shading conditions (under full sun; black shade net, and red shade net, both with 50% shading), and five replicates per treatment. The variables evaluated were plant height; stem diameter; shoot, root, and total dry matter; and leaf area. The best hydrogel dose for watermelon cultivation was 1.5 g L-1, but the higher doses impaired plant growth, regardless of shading conditions. The black net improved biomass accumulation in 'Crimson Sweet' watermelon, whereas the red net induced plant etiolation.

ABSTRACT The objective of this work was to establish DRIS norms for evaluation of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions. Cladode macro and micronutrient contents and dry matter yield of 72 plots were evaluated. The experiment was conducted in a randomized block design with three replicates, using a 4×3×2 factorial arrangement consisted of four bovine manure rates (0, 30, 60, and 90 Mg ha-1 ano-1), three spacings (1.00×0.50, 2.00×0.25, and 3.00×1.00×0.25 m), and two production cycles (600 and 930 days). The data were separated into high-yield population (HYP) and low-yield population (LYP), above and below 19.93 Mg ha-1 cycle-1, respectively. The mean, standard deviation, coefficient of variation, variances, and variance ratios of all bivariate relations between nutrients were calculated for the establishment of DRIS norms, considering the direct (A/B) and reverse (B/A) form. The selection of direct and reverse relations between nutrients to compose the DRIS norms was based on the variance ratio between LYP and HYP (S2b/S2 a). The sixty-six relations between cladode nutrient contents that presented the higher ratios between the variances in the LYP and HYP (S2b/S2a) were chosen. The DRIS norms established make viable the use of leaf diagnosis as an evaluation method of nutritional status of cactos pear of the Gigante cultivar grown under organic fertilization in semiarid conditions.

ABSTRACT Microgreens are young plants that are consumed at the seedling stage, which present short production cycle and require little space for growing. The objective of the present study was to evaluate the yield and nutritional quality of purple cabbage (Brassica oleracea var. capitata f. rubra) microgreens grown in different substrates and nutrient concentrations in the nutritive solution, in a recirculating irrigation system. The experiment was conducted in a protected environment at the Faculty of Agronomy (UFRGS), in Porto Alegre, RS, Brazil. A completely randomized design and three replications were used, with a 4×3 factorial arrangement consisted of four commercial substrates (CSC® vermiculite, Beifiur® S10, Carolina Soil® seedling, and Carolina Soil® organic) and three nutrient concentrations in the nutritive solution (0%, 50%, and 100%). A sub-irrigation system was used for the irrigations. The variables evaluate were: shoot fresh matter yield (SFMY), shoot dry matter yield (SDMY), shoot height at harvest (SHH), production cycle (precocity), and total soluble solids (TSS), total chlorophyll, and carotenoid contents. The different substrates had no effect on the SFMY, SDMY, and SHH of the purple cabbage microgreens; the increasing addition of nutrients to the nutritive solution increased the values of these variables. The TSS and total carotenoid contents decreased as the nutrient concentration in the nutritive solution was increased. The responses of total chlorophyll contents to the substrates and the nutrient concentrations in the nutritive solution varied.

ABSTRACT The use of cultivars appropriate to the soil and climate characteristics of a region provides farmers with security by facilitating credit for crop financing and improving product prices in local commerce. The objective of this work was to evaluate the agronomic performance of “Contender” and “Amarelo Japonês” green bean bush cultivars grown in the Cerrado in terms of water replenishment (RH) of 25, 50, 75, 100, and 125% of evaporation using the Piché evaporimeter. The experiment was carried out in the experimental area of the State University of Goiás, on the Ipameri Campus. The experimental design was a randomized block design. Sowing was done in May 2017, with treatments distributed in a split-plots scheme with water replenishment in plots and cultivar subplots with 3 replications. The analyzed variables were: height; stem diameter; leaf number; leaf area; number of inflorescences; number of flowers; fresh and dry mass of the plant; number, length, diameter, fresh and dry mass of the pods. The different water replenishment rates increased the mean plant height, stem diameter, number of pods per plant, number of bean seeds per pod, and number of bean seeds per plant in the cultivars “Amarelo Japonês” and “Contender.” Water replenishment of 125% produced higher development and better agronomic performance in the two cultivars than the other rates.

Published: January 2020

ABSTRACT Salt stress is one of the most limiting environmental factors for agricultural yields in the Semiarid region of Brazil. Considering the expansion of areas with sugarcane crops in this region, the selection of more adapted plant varieties to this environment is an essential tool for the sustainability of this activity. Thus, the objective of the present work was to evaluate the physiological and biochemical responses of plants of ten sugarcane varieties to salt stress. The experiment was conducted in a greenhouse using a randomized block design, in a 6×10 factorial arrangement consisting of six salinity levels in the irrigation water (0, 1.0, 2.0, 4.0, 6.0, and 8.0 dS m-1) and ten sugarcane varieties (VAT 90212, RB 72454, RB 867515, Q 124, RB 961003, RB 957508, SP 791011, RB 835089, RB 92579, and SP 943206), with three replications. Salt waters were applied every two days to increase the soil moisture to field capacity and promote leaching. The gas exchange, chlorophyll content, and total soluble and reducing sugars of leaves were evaluated at 90 days after planting. The highest chlorophyll contents were found in plants of the varieties Q 124, RB 96103, RB 835089, and SP 943206. The effect of salinity on the sugarcane plants affected their leaf gas exchanges and total soluble and reducing sugar contents, denoting the adaptability of plants to the stress conditions evaluated. The decrease of stomatal conductance resulted in decreases in photosynthetic rates in plants of all sugarcane varieties evaluated, except for RB 867515.

ABSTRACT The fruit of Cactaceas from northeastern Brazil have been the object of many ethnobotanical and functional quality studies. However, a considerable number of species remain poorly exploited, such as the facheiro (Pilosocereus pachycladus Ritter), a native Brazilian plant widely occurring and used in the Caatinga. The objectives of this research were to evaluate the quality, and antioxidant and enzymatic activities of the facheiro fruit during maturation. Fruits were harvested from areas of occurrence of plants in the Paraíba State, Brazil, at three maturity stages, which were determined based on the color of the epicarp (G - green, IP - green with purple traces, and R - completely purple). It was carried out a survey of terms sensorial descriptor terms for fruit appearance and then evaluated the physical, physicochemical, bioactive compounds, antioxidant and peroxidase (POD) activities during maturation. The fruit were described as fleshy berries, with a smooth epicarp; a round, flat shape; opaque purple color; and juicy and soft pulp when ripe. Quality varied during maturation, with the most significant changes being in coloration: the fruit became more purple over time, providing a clear indicator of maturity. With maturation, there was an increase in the content of betalains and total extractable polyphenols, as well as antioxidant activity, by DPPH radical capture method, mainly in the pulp. The pulp of the Pilosocereus pachycladus fruit is an important source of betalains, primarily betacyanins. During maturation, POD activity decreased in the pericarp and increased in the pulp and was strongly correlated with the presence of betalains and with antioxidant activity.
Impacted teeth: Their place is in the dental arch

Published: January 2020

ABSTRACT The starting point for the treatment of unerupted teeth should consider the fact that, biologically, the pericoronal follicle maintains the ability to release EGF and other mediators responsible for eruption over time. The eruptive events may be guided and directed, so that teeth may occupy the space prepared to receive them in the dental arch, as showed in the case presented to evidence the following principle to be considered in these cases: “Regardless of the position of an unerupted tooth, it may be biologically directed to its place in the dental arch. The orthodontist should apply a mechanics to guide it and park it at its site.”

Published: January 2020

ABSTRACT Objective: To develop and validate a new psychometric tool for assessing malocclusion-related quality of life among older Indian adolescents. Methods: Item generation involved analysis of existing validated tools, followed by development of new items using various qualitative steps. A draft item pool of 41 questions was initially generated and subjected to item reduction through sequential steps involving two clinical studies to ensure reliability and validity. 431 subjects aged between 15 to 18 years took part in the validation study. Principal component analysis with varimax rotation was performed to get a psychometric tool with good factorial structure and maximum variance. Results: Rotated component matrix resulted in a 20 item psychometric tool containing 4 domains with a total variance of 61.57%. Inter item, item total correlation and Cronbach α (α = 0.88) ensured good reliability. A positive correlation of the scale with global question ensured convergent validity. Independent t test showed statistically significant difference (p< 0.05) between mean score of IOTN-DHC and DAI with MRQoLQ, ensuring good construct validity. Conclusions: The newly developed psychometric tool is named as Malocclusion-Related Quality of Life Questionnaire (MRQoLQ) having 20 questions, including 2 socioeconomic items. The scale showed good reliability and initial validity, hence can be used among older adolescents with malocclusion to assess their malocclusion-related quality of life.

ABSTRACT Introduction: Canine transmigration is a rare orthodontic condition and it is relevant to perform the proper diagnose at an early age. Objective: The aim of the current study was to find out the frequency of transmigrated mandibular canines (TRC) in orthodontic patients obtained from South Asian population of Pakistan origin. Methods: Panoramic radiographs of 2,550 untreated orthodontic patients (1,248 males; 1,302 females) were included, to investigate the presence, site, and type of TRC. Any permanent mandibular canine that was found to be crossing the midline in panoramic radiographs was considered as TRC. Results: The frequency of TRC was found to be 0.98%. TRC were only found unilaterally. No significance regarding gender and side was found. Nineteen TRC displayed a type 1 transmigratory pattern, while type 2 and type 5 transmigratory patterns were encountered in three patients. Conclusion: Frequency of transmigrated mandibular canines in the studied sample was 0.98%.

Authors: Miguel José Augusto Mendes , Freitas Tatiana Ettore do Valle de Sousa
Published: January 2020

ABSTRACT The demand for orthodontic treatment in adults has been increasing. However, these patients often require a multidisciplinary approach, due to the lack of posterior teeth, requiring additional anchorage. The skeletal anchorage by endosseous implants is an option, since they may be used later for prosthetic rehabilitation. The application of immediate load on these appliances for orthodontic movement may reduce the costs and total treatment time. This paper discusses the utilization of endosseous dental implants with immediate load for absolute anchorage for orthodontic movement, with later utilization for prosthetic rehabilitation.

Abstract The use of color shading meshes is presented as a new technological approach to manage flowers and ornamental plants. Eustoma grandiflorum (Raf.) Shinners is a flower that excites interest of producers and consumers. However, there is little technical and scientific information on its production and management. We evaluated the incidence of arthropods and phytotechnical characteristics in two cultivars of cut lisianthus, under the influence of different color shading meshes in commercial greenhouse. The experiments were conducted in the company Floricultura Florist, Dois Irmãos-RS, Brazil. The experiment took place from August to December 2012 and tested the influence of shading meshes with different colors (gray, red, black, and blue) on two varieties of cut lisianthus (Mariage and Bolero White). In each treatment, the phytotechnical characteristics of the plants assessed and arthropod samples were collected. Red mesh produced the best results, and blue, the worst. Nine orders of arthropods from 24 families with different habits were observed. Diptera was the most abundant. The shading screens did not influence the number of arthropods in plants.

Abstract Adenium obesum (Forssk.) Roem. & Schult., widely known as desert rose, has attracted interest for its esthetic characteristics, which are influenced by the process of seedling production. Using two consecutive experiments installed fully at random, the study aimed at assessing the use of different substrates and hydrogel to produce desert rose seedlings in a protected environment. First, eleven substrates were tested, prepared as follows: OrganoAmazon®; PuroHumus®; soil; rice husk in natura; carbonized rice husk, sawdust and cattle manure. Then, three substrates were tested (S1 - OrganoAmazon® + PuroHumus®; S2 - OrganoAmazon® + PuroHumus® + rice husk in natura and S3 - OrganoAmazon® + PuroHumus® + carbonized rice husk) associated to four hydrogel levels: 0 (daily irrigation), 1, 2 and 3 g L−1 (irrigated on alternate days). Growth variables and quality index of seedlings were assessed. Six substrates (all of them without addition of sawdust and where used in mix) were grouped as those the promoted appropriate growth of seedlings, with height, number of leaves, collar diameter, root length and aerial part biomass superior to 6.5 cm; 13; 12 mm; 7.5 cm and 0.45 g, respectively. The substrate composed of OrganoAmazon® + PuroHumus® (1:1 v/v), when irrigated daily, was the one that favored most the production of quality seedlings. The use of hydrogel in substrates with shifts of irrigation on alternate days did not favor the production of desert rose seedlings.

Published: January 2020

Abstract Zamioculcas zamiifolia (Araceae) is one of the most widely grown exotic species in Brazil as ornamental plants and in landscape design. Despite tolerating transport and being well adapted to low-light environments, this ornamental is attacked by different pathogens. Thus, the aim was to detect and identify the pathogen that causes stem rot in commercial Z. zamiifolia crops. Z. zamiifolia plants exhibiting stem rot symptoms were sent for phytosanitary diagnosis. In a culture medium, the fungal isolate obtained (SR-001) displayed the following morphological characteristics: cotton-like aerial mycelium, septate hyaline hyphae with no spore production, and the formation of small brown spherical sclerotia. To confirm pathogenicity, Z. zamiifolia plants were inoculated with the SR-001 isolate and, after fifteen days, the fungus was re-isolated when the same rot symptoms emerged. The SR-001 isolate was identified as Sclerotium rolfsii and its representative sequence was deposited in GenBank (Access MG694322). This fungal isolate has not been associated with diseases in Z. zamiifolia in Brazil, and this is the first report of the fungus infecting this ornamental plant species in a cultivated area.

Authors: Lima Suzanny da Silva , Fernandes Daniel Santos
Published: January 2020

Este artigo tem por objetivo apresentar os primeiros resultados de uma pesquisa em andamento, sobre construções culturais, que está sendo realizada na Agrovila Princesa do Xingu, em Altamira-Pará. Uma breve discussão acerca do conceito de cultura dentro da abordagem etnográfica foi construída a fim de se pautar as referências nas quais os resultados em questão foram coletados. Para tanto, as perspectivas de Geertz (1989) e Albó (2005) acerca de cultura foram norteadoras quanto ao entendimento das construções culturais dos moradores da Agrovila em questão após aproximadamente 46 anos de sua fundação. Além disso, a abordagem etnográfica de investigação científica na visão de Geertz (1989) e Mattos (2011) também é parâmetro para os dados aqui apresentados. Instrumentos da etnografia como observação participante, notas de campo, registro fotográfico e entrevistas foram utilizados para a coleta dos dados realizada até o presente momento.

MuKuiú é palavra bantu, que traduz o pedido de bênçãos como saudação e respeito aos nossos ancestrais. Este vídeo etnográfico foi gerado como uma das dobras artísticas do processo de pesquisa premiada pelo Programa Seiva 2018, edital de pesquisa e experimentação artística. Este projeto tem como motriz o engajamento do corpo dos artistas-pesquisadores, que experimentam performances negras na Amazônia como (re)existências; refletem sobre a importância do candomblé e das religiões de matriz africana para a dança artística afro no Brasil; e ainda, revisitam os elementos de dança presentes na capoeira. E as experiências de campo foram realizadas no espaço do terreiro de candomblé angola Mansu Nangetu e no espaço da Associação Cultural Eu Sou Angoleiro – Treinel Edimar. Partindo do método etnográfico e de oficinas de intercâmbio de técnicas corporais, experimentadas como fontes e ressignificadas junto a um grupo de artistas pesquisadores, o que compartilhamos neste vídeo é um convite para a apreciação de outras instaurações artísticas que se descortinaram neste processo de pesquisa e experimentação, que busca uma possível aproximação entre ritual e arte.Assistia aqui.

Legal regulation of social entrepreneurship in Russia
Authors: Savina Anna Vladimirovna , Pridvorov Nikolay Antonovich
Published: January 2020

We consider the issues of entrepreneurship and social entrepreneurship correlation; analyze the concepts definitions of “social entrepreneurship”, “socially oriented noncommercial organization”, “social enterprise”; comprehend the issues of the social entrepreneurs legal status, consider the regulatory procedure for recognizing a small or medium-sized business as a social enterprise. It is noted that the difference between “entrepreneurship” and “social entrepreneurship” depends on the goal that guides the participant in civil relations. We analyze and correlate the private-legal and public-legal foundations for social entrepreneurs support, we study the issue of social en-trepreneurship in foreign countries; attention is paid to the aspect of state support for social entrepreneurs, socially oriented noncommercial organiza-tion. We emphasize the necessity of developing a legal concept for the devel-opment of social entrepreneurship in Russia, which underlies the selection of projects that could qualify for one of the forms of state support in the field of social entrepreneurship. We consider the issue of social contract. We outline the idea of agreements differentiation concluded in the field of social entrepreneurship on the basis of the state participation in such relations. It is emphasized that agreements can be the result of proactive entrepreneurship aimed at achieving a socially beneficial result and not claiming financial support from the state, but, on the contrary, can be of a cascading nature and include no less than three parties, one of which is the state.
The pseudospectrum of the convention-diﬀusion operator with a variable reaction term

In this paper, we study the spectrum of non-self-adjoint convection-diﬀusion operator with a variable reaction term deﬁned on an unbounded open set Ω of R^n. Our idea is to build a family of operators that have the same convection-diﬀusion-reaction formula, but which will be deﬁned on bounded open sets 〖{Ω_η}〗_(η∈]0,1[) of R^n. Based on the relationships that link this family to Ω, we obtain relations between the spectrum and the pseudospectrum. We use the notion of the pseudospectrum to build relationships between convection-diﬀusion operator and its restrictions to bounded domains. Using these relationships we are able to ﬁnd the spectrum of our operator in R^+. Also, the techniques developed to obtain the spectrum allow us to study the properties of the spectrum of this operator when we go to the limit as the reaction term tends to zero. Indeed, we show a spectral localization result for the same convection-diﬀusion-reaction operator when a perturbation is carried on the reaction term and no longer on the deﬁnition domain.
Decomposition of boundary representations on the Lobachevsky plane associated with linear bundles
Authors: Grosheva Larisa I.
Published: January 2020

Earlier we described canonical (labelled by λ ∈C) and accompanying boundary representations of the group G = SU(1,1) on the Lobachevsky plane D in sections of linear bundles and decomposed canonical representations into irreducible ones. Now we decompose representations acting on distributions concentrated at the boundary of D. In the generic case 2λ ∉N they are diagonalizable, in the exceptional case Jordan blocks appear.
Juventude rural e ensino superior público

Published: January 2020

Observa-se que nos últimos anos houve um processo de interiorização do ensino superior no Brasil, advindo principalmente da política pública de reestruturação e expansão das universidades federais, instituída em 2007. No entanto, em que medida esse processo pode ser considerado como de mudanças nas trajetórias de vida de grupos sociais historicamente marginalizados? Para desencadear tal discussão, este artigo analisa as trajetórias escolares de jovens estudantes rurais de um campus universitário público do Nordeste do Brasil. Trata-se de um estudo quantitativo, descritivo, com amostragem aleatória de estudantes dos cursos das áreas de ciências exatas e biológicas, no qual foram utilizados o questionário e o diário de campo como instrumentos de coleta de dados; a estatística descritiva e a análise de conteúdo, como procedimentos de análise desses dados. Os resultados apontaram para um perfil de jovens com idade que varia entre 18 a 33 anos; trajetória escolar de migração para espaços citadinos, como motivação para continuar os estudos devido à precarização da educação nos espaços rurais; e perspectivas de futuro voltadas para o ensino superior objetivando a ascensão financeira para ajudar a família e seus territórios. Portanto, esse estudo sugere que os programas de interiorização e expansão das universidades federais estão sendo um aliado nas trajetórias de mudanças dos jovens e das jovens das áreas rurais.

Published: January 2020

O presente artigo sobre formação do professor para a Educação Superior, se justifica pela relevância e protagonismo que esse processo tem, em um cenário de preocupação com a Educação Básica, decorrente das orientações político-econômicas das organizações multilaterais a que se submetem os países Latinos Americanos. Com o objetivo de analisar, por meio de pesquisa do tipo “Estado da Arte”, a produção científica que focaliza a formação de professores para a Educação Superior em cinco eventos da área de Educação no Brasil (ANPAE 2015, ANPEd 2015, ANPEd SUL 2014 e 2016 e EDUCERE 2015). Teve aportes teóricos de diversos autores, bem como documentos legais, como a LDB (1996) e o PNE (2014), entre outros, subsidiaram a análise dos artigos aprovados e publicados que discutiram a formação do professor para a Educação Superior. Os resultados indicam que a formação desse professor, ao estar pautada em conhecimentos técnicos e científicos e em conhecimentos de como se desenvolve o processo de ensino-aprendizagem, deve possibilitar uma formação que os prepare para realizarem análises críticas e reflexivas de sua prática e do próprio contexto em que atuam (Educação Superior).  Reitera-se a importância dessas análises e de pesquisas para a proposição de subsídios para a formulação de políticas públicas voltadas para essa formação.

➤ Necrotizing fasciitis hijacks the acute phase response, increasing the risk of developing pathophysiologic states commonly associated with death: sepsis-induced coagulopathy (SIC), systemic inflammatory response syndrome (SIRS), and adrenal insufficiency, referred to as critical illness-related corticosteroid insufficiency (CIRCI).

➤ Dynamic monitoring of SIC, SIRS, and CIRCI may be informative when assessing infection severity and when directing treatment to manage these conditions as soon as they begin to develop.

➤ To reduce the risk of oropharyngeal colonization, N95 respirators should be worn by health-care professionals who are operating on patients with necrotizing fasciitis.

Published: January 2020

Background:

Intramedullary (IM) nailing is the treatment of choice for most tibial shaft fractures. However, an iatrogenic pitfall may be rotational malalignment. The aims of this retrospective analysis were to determine (1) the prevalence of rotational malalignment using postoperative computed tomography (CT) as the reference standard; (2) the average baseline tibial torsion of uninjured limbs; and (3) based on that normal torsion, whether the contralateral, uninjured limb can be reliably used as the reference standard.

Methods:

The study included 154 patients (71% male and 29% female) with a median age of 37 years. All patients were treated for a unilateral tibial shaft fracture with an IM nail and underwent low-dose bilateral postoperative CT to assess rotational malalignment.

Results:

More than one-third of the patients (n = 55; 36%) had postoperative rotational malalignment of ≥10°. Right-sided tibial shaft fractures were significantly more likely to display external rotational malalignment whereas left-sided fractures were predisposed to internal rotational malalignment. The uninjured right tibiae were an average of 4° more externally rotated than the left (mean rotation and standard deviation, 41.1° ± 8.0° [right] versus 37.0° ± 8.2° [left]; p < 0.01). Applying this 4° correction to our cohort not only reduced the prevalence of rotational malalignment (n = 45; 29%), it also equalized the distribution of internal and external rotational malalignment between the left and right tibiae.

Conclusions:

This study confirms a high prevalence of rotational malalignment following IM nailing of tibial shaft fractures (36%). There was a preexisting 4° left-right difference in tibial torsion, which sheds a different light on previous studies and current clinical practice and could have important implications for the diagnosis and management of tibial rotational malalignment.
