Aims Although good clinical outcomes have been reported for monolithic tapered, fluted, titanium stems (TFTS), early results showed high rates of subsidence. Advances in stem design may mitigate these concerns. This study reports on the use of a current monolithic TFTS for a variety of indications. Methods A multi-institutional retrospective study of all consecutive total hip arthroplasty (THA) and revision total hip arthroplasty (rTHA) patients who received the monolithic TFTS was conducted. Surgery was performed by eight fellowship-trained arthroplasty surgeons at four institutions. A total of 157 hips in 153 patients at a mean follow-up of 11.6 months (SD7.8) were included. Mean patient age at the time of surgery was 67.4 years (SD 13.3) and mean body mass index (BMI) was 28.9 kg/m2 (SD 6.5). Outcomes included intraoperative complications, one-year all-cause re-revisions, and subsidence at postoperative time intervals (two weeks, six weeks, six months, nine months, and one year). Results There were eight intraoperative complications (4.9%), six of which were intraoperative fractures; none occurred during stem insertion. Six hips (3.7%) underwent re-revision within one year; only one procedure involved removal of the prosthesis due to infection. Mean total subsidence at latest follow-up was 1.64 mm (SD 2.47). Overall, 17 of 144 stems (11.8%) on which measurements could be performed had >5 mm of subsidence, and 3/144 (2.1%) had >10 mm of subsidence within one year. A univariate regression analysis found that additional subsidence after three months was minimal. A multivariate regression analysis found that subsidence was not significantly associated with periprosthetic fracture as an indication for surgery, the presence of an extended trochanteric osteotomy (ETO), Paprosky classification of femoral bone loss, stem length, or type of procedure performed (i.e. full revision vs conversion/primary). Conclusion Advances in implant design, improved trials, a range of stem lengths and diameters, and high offset options mitigate concerns of early subsidence and dislocation with monolithic TFTS, making them a valuable option for femoral revision.

AimsTo investigate the benefits of denosumab in combination with nerve-sparing surgery for treatment of sacral giant cell tumours (GCTs).MethodsThis is a retrospective cohort study of patients with GCT who presented between January 2011 and July 2017. Intralesional curettage was performed and patients treated from 2015 to 2017 also received denosumab therapy. The patients were divided into three groups: Cohort 1: control group (n = 36); cohort 2: adjuvant denosumab group (n = 9); and cohort 3: neo- and adjuvant-denosumab group (n = 17).ResultsThere were 68 patients within the study period. Six patients were lost to follow-up. The mean follow-up was 47.7 months (SD 23.2). Preoperative denosumab was found to reduce intraoperative haemorrhage and was associated with shorter operating time for tumour volume > 200 cm3. A total of 17 patients (27.4%) developed local recurrence. The locoregional control rate was 77.8% (7/9) and 87.5% (14/16) respectively for cohorts 2 and 3, in comparison to 66.7% (24/36) of the control group. The recurrence-free survival (RFS) rate was significantly higher for adjuvant denosumab group versus those without adjuvant denosumab during the first two years: 100% vs 83.8% at one year and 95.0% vs 70.3% at two years. No significant difference was found for the three-year RFS rate.ConclusionPreoperative denosumab therapy was found to reduce intraoperative haemorrhage and was associated with shorter operating times. Adjuvant denosumab was useful to prevent early recurrence during the first two years after surgery. Cite this article: Bone Joint J 2020;102-B(2):177–185.
Supine flexibility predicts curve progression for patients with adolescent idiopathic scoliosis undergoing underarm bracing
Authors: Cheung Jason P. Y. , Cheung Prudence W. H. 
Published: February 2020

Aims The aim of this study was to assess whether supine flexibility predicts the likelihood of curve progression in patients with adolescent idiopathic scoliosis (AIS) undergoing brace treatment. Methods This was a retrospective analysis of patients with AIS prescribed with an underarm brace between September 2008 to April 2013 and followed up until 18 years of age or required surgery. Patients with structural proximal curves that preclude underarm bracing, those who were lost to follow-up, and those who had poor compliance to bracing (<16 hours a day) were excluded. The major curve Cobb angle, curve type, and location were measured on the pre-brace standing posteroanterior (PA) radiograph, supine whole spine radiograph, initial in-brace standing PA radiograph, and the post-brace weaning standing PA radiograph. Validation of the previous in-brace Cobb angle regression model was performed. The outcome of curve progression post-bracing was tested using a logistic regression model. The supine flexibility cut-off for curve progression was analyzed with receiver operating characteristic curve. Results A total of 586 patients with mean age of 12.6 years (SD 1.2) remained for analysis after exclusion. The baseline Cobb angle was similar for thoracic major curves (31.6° (SD 3.8°)) and lumbar major curves (30.3° (SD 3.7°)). Curve progression was more common in the thoracic curves than lumbar curves with mean final Cobb angles of 40.5° (SD 12.5°) and 31.8° (SD 9.8°) respectively. This dataset matched the prediction model for in-brace Cobb angle with less mean absolute error in thoracic curves (0.61) as compared to lumbar curves (1.04). Reduced age and Risser stage, thoracic curves, increased pre-brace Cobb angle, and reduced correction and flexibility rates predicted increased likelihood of curve progression. Flexibility rate of more than 28% has likelihood of preventing curve progression with bracing. Conclusion Supine radiographs provide satisfactory prediction for in-brace correction and post-bracing curve magnitude. The flexibility of the curve is a guide to determine the likelihood for brace success. Cite this article: Bone Joint J 2020;102-B(2):254–260.

AimsTo evaluate the donor site morbidity and tendon morphology after harvesting whole length, full-thickness peroneus longus tendon (PLT) proximal to the lateral malleolus for ligament reconstructions or tendon transfer.MethodsA total of 21 eligible patients (mean age 34.0 years (standard deviation (SD) 11.2); mean follow-up period 31.8 months (SD 7.7), and 12 healthy controls (mean age, 26.8 years (SD 5.9) were included. For patients, clinical evaluation of the donor ankle was performed preoperatively and postoperatively. Square hop test, ankle strength assessment, and MRI of distal calf were assessed bilaterally in the final follow-up. The morphological symmetry of peroneal tendons bilaterally was evaluated by MRI in healthy controls.ResultsAmong the patients, the mean pre- and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Karlsson-Peterson score were 98.7 (SD 2.5; p = 0.480) and 98.5 (SD 2.4; p = 0.480), and 98.3 (SD 2.4; p = 0.162) and 97.9 (SD 2.5; p = 0.162), respectively. There was no significant difference between square hop test bilaterally (p = 0.109) and plantar flexion peak force bilaterally (p = 0.371). The harvested limb had significantly less eversion peak force compared to the contralateral limb (p < 0.001). Evidence of probable tendon regeneration was observed in all the patients by MRI and the total bilateral peroneal tendon index (mean ratio of harvested side cross-sectional area of peroneal tendon compared with the contralateral side) was 82.9% (SD 17.4). In 12 healthy controls, peroneal tendons (mean 99.4% (SD 4.3) were found to be morphologically symmetrical between the two sides.ConclusionThe current study showed satisfactory clinical foot and ankle outcomes after full-thickness PLT harvesting and indicated the regenerative potential of PLT after its removal.

Aims Idiopathic scoliosis is the most common spinal deformity in adolescents and children. The aetiology of the disease remains unknown. Previous studies have shown a lower bone mineral density in individuals with idiopathic scoliosis, which may contribute to the causation. The aim of the present study was to compare bone health in adolescents with idiopathic scoliosis with controls. Methods We included 78 adolescents with idiopathic scoliosis (57 female patients) at a mean age of 13.7 years (8.5 to 19.6) and 52 age- and sex-matched healthy controls (39 female patients) at a mean age of 13.8 years (9.1 to 17.6). Mean skeletal age, estimated according to the Tanner-Whitehouse 3 system (TW3), was 13.4 years (7.4 to 17.8) for those with idiopathic scoliosis, and 13.1 years (7.4 to 16.5) for the controls. Mean Cobb angle for those with idiopathic scoliosis was 29° (SD 11°). All individuals were scanned with dual energy x-ray absorptiometry (DXA) and peripheral quantitative CT (pQCT) of the left radius and tibia to assess bone density. Statistical analyses were performed with independent-samples t-test, the Mann-Whitney U test, and the chi-squared test. Results Compared with controls, adolescents with idiopathic scoliosis had mean lower DXA values in the left femoral neck (0.94 g/cm2 (SD 0.14) vs 1.00 g/cm2 (SD 0.15)), left total hip (0.94 g/cm2 (SD 0.14) vs 1.01 g/cm2 (SD 0.17)), L1 to L4 (0.99 g/cm2 (SD 0.15) vs 1.06 g/cm2 (SD 0.17)) and distal radius (0.35 g/cm2 (SD 0.07) vs 0.39 g/cm2 (SD 0.08; all p ≤ 0.024), but not in the mid-radius (0.72 g/cm2 vs 0.74 g/cm2; p = 0.198, independent t-test) and total body less head (1,559 g (SD 380) vs 1,649 g (SD 492; p = 0.0.247, independent t-test). Compared with controls, adolescents with idiopathic scoliosis had lower trabecular volume bone mineral density (BMD) on pQCT in the distal radius (184.7 mg/cm3 (SD 40.0) vs 201.7 mg/cm3 (SD 46.8); p = 0.029), but not in other parts of the radius or the tibia (p ≥ 0.062, Mann-Whitney U test). Conclusion In the present study, idiopathic scoliosis patients seemed to have lower BMD at central skeletal sites and less evident differences at peripheral skeletal sites when compared with controls.

Published: February 2020

The anion and cation deficient phase Bi0.95 In0.05 O1.5 (Bi1.9 In0.1 O3) was synthesized and experimentally investigated using X-ray diffraction and vibrational spectroscopy (Infrared and Raman). The non-stoichiometric phases are similar to sillenite family type γBi2O3 and crystallize in the I23 space group. The crystal structure was determined by full profile Rietveld analysis of the powder diffractogram. It is formed by a sequence of BiO5E polyhedra (E lone pair of bismuth) and MO4 polyhedra (M = In, Mg). The set of MO4 polyhedra are localized in cavities generated by BiO5E polyhedra. The vibrational spectroscopic study revealed the existence of three regions; low, intermediate and high-frequency region. They are attributed to Bi-O stretching mode, In / Mg-O vibrations and cationic displacements respectively.
When equal partners become unequal parents: couple relationships and intensive parenting culture
Authors: Faircloth Charlotte 
Published: February 2020

Based on longitudinal research with (heterosexual) couples in the UK, this article tracks their experiences of becoming parents for the first time. The suggestion is that new parents are caught in an uncomfortable confluence between competing discourses around ideal relationships and those around ideal parenting. On the one hand, they must be committed to egalitarian ideals about the division of care. On the other, they must be parenting ‘intensively’, in ways which are markedly more demanding for mothers, and which makes paternal involvement more complicated.
Drawing on accounts of relationship difficulties, elicited over a five-year period, the article demonstrates the incommensurability of these ideals at physiological, material and ideological levels. As a contribution to the body of work known as parenting culture studies, this article brings, for the first time, an empirical focus to the question of how an ‘intensive’ parenting culture affects couples, rather than just mothers or fathers.
Between nature and culture: Jakob von Uexküll's concept of Umwelten and how photography shapes our worlds
Authors: Froese Joachim 
Published: February 2020

Abstract
This article addresses traditional perceptions about photography's position between nature and culture and concomitant schools of thinking focusing pre-dominantly on the photographic image as a form of visual representation. Aiming to develop an alternative perspective it considers a biosemiotic approach and turns to Jakob von Uexküll's model of subjective sentient worlds (Umwelt) that critically dissolves the perceived dualism between nature and culture that has also underpinned most theoretical thinking about photography in the past. Today photography is largely embedded into social media platforms and their interlinked digital networks, which holds far-reaching consequences for a medium that in this current form can only be fully understood if it is considered as a form of embodied material practice. Aiming to understand some of the complex manifestations this technical evolution entails the article further considers the relevance of recent non-representational concepts arising out of cognition theory and cultural geography and uses the 'selfie' as a 'theoretical object'.
Photographic art and technology in contemporary India
Authors: Blaney Aileen 
Published: February 2020

Abstract
The algorithmic turn in photography raises the question of whether an algorithmically generated image is even a photograph at all. This paradox is abundant on India's urban streets, where the pedestrian or road user is met with giant photo saturated flex hoardings printed with political and community messages and photo-shopped portraits of gods, chief ministers and party workers. In this article, attention to photo-based political posters alongside art practices sharing common elements of digital capture and postproduction contextualizes a reading of technologically produced visual landscapes in the South Indian city of Bangalore. Informed by Vilèm Flusser, the techno-materiality of hoardings are interpreted as visual practices whose reliance on Microsoft and Adobe softwares reveal more than the semiotic information that is ostensibly transmitted; in so doing the extent to which photography is a useful entry point for assessing the visuality in which we're currently living and how this gets locally inflected in the case of India is explored.
Adrian Piper's aesthetic agency: Photography as catalysis for resisting neo-liberal competitive paradigms
Authors: Puymbroeck Gerlinde Van 
Published: February 2020

Abstract
Contemporary neo-liberal society is ruled by the market. Davies, Chen and Lentin and Titley show that its objectification and categorization founds a competitive notion of agency that disables subjective construction of self and intersubjective understanding of the world. As the market's rules and norms are set by white patriarchy, its competitive paradigm structurally disadvantages others. Art too is objectified and categorized by neo-liberal institutions, equally embedded in white patriarchal market structures and severely limiting democratic public access to a diverse artistic field, argue hooks, Mercer and Piper. Yet, Piper's artwork shows, art holds emancipatory potential. Defined as transforming experience, its ambiguity provides a structure for constituting agentic subjectivity and intersubjective signification processes, defying objective/objectifying market workings. Photography's specific qualities allow Piper to democratize access to the paradigm she proposes. Her artistic choices may thus found the potential to publicly construct a notion of aesthetic agency as resistance to the neo-liberal market.
Photographic manipulation in the health, clinical and biomedical sciences
Authors: Schneider Catherine , Hoffmann Sydney , Rowles Graham D. 
Published: February 2020

Abstract
Photography has become a pervasive component of contemporary communication. Recent technological advances in creating and manipulating images have provided renewed impetus to decades-long debates on use of photographs in science. With increase in the potential for inappropriate image manipulation, fears about misrepresentation have heightened concern among journal editors and scholars about the 'accuracy' of published images. We discuss how science has responded to growing concerns surrounding falsification and inaccuracy of photography. We document progress in implementing a variety of complementary approaches to addressing the problem. These include digital forensics, photo member checking and the implementation of codes of ethics to enhance the veracity of published photographs in science research. We conclude by acknowledging the irreducible conflict likely to remain between use of the photograph as a creative work of art and employment of this medium as a source of information in the progress of science.
This misery of light – light as destruction in the work of Lina Selander
Authors: Larsson Erika 
Published: February 2020

Abstract
In this article I look at two works by Swedish video artist Lina Selander and explore how underlying visual patterns unfold in these works that are connected to certain worldly phenomena. Borrowing from Jacques Derrida, I describe the tendency of being en mal d'archive as an obsession to structure the world into particular recognizable patterns. I argue that Selander's works can be understood as the unfolding of such structures, the result being that the very impulse itself, the obsession Derrida speaks of, comes to the forefront. In several of Selander's works, light is explored both as a basis and prerequisite for photography and as a metaphor for this potentially destructive desire for all-encompassing knowledge and structure. As such, I argue, the unfolding that takes place in her works can be understood as paradoxically increasing the shadows – as a way of undoing the totalizing effect of light and articulating modes of not knowing or mystery in relation to the phenomena explored.
Where is the photography of Non-Photography?
Authors: Whittaker Ed 
Published: February 2020

Abstract
François Laruelle's writing on Non-Photography is examined from its ontological condition to its desired form of a unity derived from the work of Kant, discussing precisely how the logic of transcendence and the ontology of immanence central to Laruelle's theory impact on how the photographic image is incontrovertibly involved with Kant's paradox of appearance and reality. In a context of burgeoning technoscience, which lays bare the meaning of Non-Photography for the seemingly impossible reversion to actual photography, the article goes on to consider Photo-Fiction in the context of the Real of science now yoked to an economy of technical models. But by foreclosing the Kantian Real by fractal–virtual ratio, does not this science reify the Real of Identity and displace real photography with a photography in the Real? The article thus questions how Laruelle's' thesis hangs together in terms of its cause and the contingency of effect that infuses Laruelle's radical aesthetic.
Does working capital management affect the profitability of commercial banks: the case of Kosovo
Authors: Mazreku Ibish , Morina Fisnik , Zeqaj Florentina 
Published: February 2020

Purpose: This paper aims to analyze working capital and its impact on the profitability of commercial banks. The other objectives of this study are to analyze the factors that influence the profitability of commercial banks, to find out the relationship between profitability and working capital management. To achieve these research objectives, several research questions have been posited: How much does working capital affect the profitability of commercial banks? What are the relationships between bank profitability and bank size, debt ratio and current ratio? What are the other factors affecting the profitability of commercial banks?
Methodology: The empirical data to be used in this research are secondary data and will be based on annual reports of commercial banks and reports of the Central Bank of Kosovo. From these data, some indicators such as return on assets, current ratio, debt ratio and banks’ size will be calculated. This research covers a period of 5 years and the data will be analyzed and interpreted through econometric models. In addition, to analyze the impact of working capital on the profitability of commercial banks in Kosovo, trend analysis will also be applied through the comparative method.
Findings: Based on the empirical results, we can conclude that bank size and the current ratio have positively affected the performance of commercial banks in Kosovo, whereas the debt ratio has had a negative effect. All the independent variables in relation to the dependent variable (ROA) are at the standard level of significance P-value = 0.05.
Practical implications: Through this study we can recommend all commercial banks in Kosovo to invest much more in working capital, since financial investments in working capital affect the bank's profitability. This means that a high investment in the elements of working capital can lead to increased bank profitability, whereas its profitability decreases when investment in working capital is low.
Originality: This paper presents real and sustainable results with respect to the conclusions. The period analyzed (2013-2017) is a persuasive period for drawing competent conclusions and recommendations.
Keywords: working capital, debt ratio, current ratio, bank size, return on assets
