No full textPresentiamo il caso di un ragazzo di 20 anni che ha riportato un trauma complesso del ginocchio e della gamba in seguito ad un incidente motociclistico. Inizialmente è passata misconosciuta una lussazione tibioperoneale prossimale, trattata poi a distanza di due settimane con una vite transarticolare. Tale lussazione è stata diagnosticata a seguito della comparsa di un deficit dell'EPA, regredito a distanza di sei mesi
Trauma complesso dell'arto inferiore con lesione completa del tendine rotuleo e perdita di sostanza
No full textPresentiamo il caso di un giovane di 25 anni che, in seguito ad un incidente motociclistico ha riportato un trauma complesso dell'arto inferiore con plurime fratture esposte (tibia, femore, rotula) Gustilo III B e lesione del tendine rotuleo con perdita di sostanza. Il Paziente è statao trattato in urgenza con toilette e debridement conservativo dei tessuti e stabilizzazione temporanea con fissatore esterno a ponte. In un secondo tempo si è proceduto a stabilizzazione definitiva con FEA, sintesi dei condili femorali e del piatto tibiale con viti cannulate e reiserzione del tendine rotuleo con ancorette. In associazione è stato eseguito intervento di chirurgia plastica. A distanza di sei mesi è stato rimosso il FE e al controllo clinico l'estensione del ginocchio è completa
Forearm segmental bone defect: Successful management using the Masquelet Technique with the aid of 3D printing technology
No full text: The management of forearm nonunion is challenging for orthopaedic surgeons because the forearm is a unique anatomical segment in which all the bones and structures involved embody a complex functional unit. Therefore, when treating such a complex condition, the surgeon must focus not only on bone healing but also on the restoration of the native anatomy in order to replicate the normal relationship between the bones and all the surrounding structures and thus the full function of the forearm, the elbow and the wrist. Here we report the case of a 53-year-old patient with a left forearm deformity due to an atrophic nonunion of the ulna and a malunion of the radius, which was successfully managed with the use of the Masquelet technique associated with a corrective osteotomy of the radius, performed with the aid of a 3D model
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Distal biceps tendon rupture: ten-year experience using suture anchors through a single anterior approach
No full textBACKGROUND: Distal biceps tendon rupture is an uncommon injury involving the dominant arm in middle-aged male population. With this retrospective cohort study, we reported the clinical outcomes of patients treated with tendon reinsertion using suture anchors through a single anterior approach. METHODS: Eighty-eight patients with distal biceps tendon rupture were treated in between 2010 and 2020 and they were evaluated at follow-up considering the recovery of ROM in flexion-extension and pronation-supination and the DASH, MAYO, and OXFORD scores. RESULTS: The ROM recovery shows fine results, with an average of flexion-extension of 135°-5° and pronation-supination 90-85°. The average DASH Score was 1.3; the average MAYO Elbow Score was 98.87 and the OXFORD Elbow Score was 47.8. There were reported four complications: one case of partial re-rupture, two cases of superficial infection, one case of anchor avulsion from bone. We had no cases of nerve palsy, radio-ulnar synostosis, or heterotopic ossifications. CONCLUSIONS: The clinical outcomes obtained by anatomical reinsertion of distal biceps tendon in its anatomical site by means of suture anchors are satisfactory and the single anterior approach can minimize the risk of nerve injury and heterotopic ossifications
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
