Temporary bridging external fixation in distal tibial fracture.
No full textFractures that involve the distal area of the tibia are associated with a high percentage of complications. Soft tissue oedema, swelling, blisters, skin abrasions and open wounds could compromise the outcome of these lesions. The waiting time before surgery with ORIF is mostly due to soft tissue conditions. Early application of a simple joint-spanning external fixator would achieve the initial goal of stability and the respect of soft tissue, thereby decreasing the time necessary for definitive treatment. A total of 40 consecutive patients (22 male and 18 female) with a mean age of 52 years (range 17-82 years) with distal tibial fracture treated between January 2010 and January 2013 were evaluated. Early temporary external fixation was the first treatment step. Twenty patients had pilon fractures, characterised by the intra-articular involvement of the distal tibia with metaphyseal extension, and 20 patients had malleolar fracture-dislocation. Patients were divided into two groups, A and B. Group A comprised 10 patients with ankle fracture-dislocation and bone fragmentation, who were treated with a temporary bridging external fixation that was maintained after ORIF to exploit ligamentotaxis during the first phases of bone healing. In Group B (30 patients), the external fixation was removed after ORIF. The results of the study are in line with the recent literature: temporary external fixation in high-energy trauma and fracture-dislocation of the ankle enables soft tissue to be restored, which facilitates postoperative assessment of bone fragments by CT scan. The complication rate in this study was 5% in patients with malleolar fractures and 20% in patients with pilon fractures. The maintenance of temporary external fixation after ORIF synthesis during the entire first stage of bone healing seems to be a good method of treatment that has a low rate of soft tissue complications
A complication following ACL reconstruction using bioabsorbable cross-pins
Get PDFThis is a case of a proximal pin migration after ACL reconstruction in medial soft tissue with pain, inflammatory reaction and functional reduction. 33-year-old male presented at our clinic with a complete ACL rupture. Reconstruction with autogenous gracilis and semitendinosus hamstring tendons was performed and graft fixed in the femoral canal with two PLLA bioabsorbable pins (RIGIDFIX® Cross Pin System). Two months postoperatively the patient presented swelling and pain on the medial side of the knee, full range of motion and negative results at the Lachman and Pivot shift tests. MRI examination showed the superior femoral tunnel crossing both the lateral and medial cortex lodging the pin in the knee’s medial soft tissue corresponding to the swelling area reported by the patient. The tendon graft was properly positioned. After surgical removal of the pin through a small skin incision, the pain and swelling promptly subsided allowing the patient return to normal activities in few weeks without any pain. In our opinion the painful swelling of the knee was due to a displacement of the pin that had been accidentally lodged in the soft tissues instead of the bone causing a foreign-body reaction resulting in granuloma formation with local inflammation. This dislodgement could have been due to an inappropriately long femoral tunnel
Use of a non-medicated plaster in shoulder tendinopathies
Get PDFWe assessed 20 shoulders with rotator cuff tendinopathy and partial tendon tears treated with FIT® plasters (far infrared technology). The criteria for inclusion were pain at night and during active shoulder movement. Patients with restricted passive movement (adhesive capsulitis) and complete tendon tears were excluded. Two different types of FIT® plasters were used according to the different power of action. Plasters were replaced after 7 days and dismissed after 15 days. The patients were assessed using the VAS pain scale and the Constant Murley score for function. The use of FIT® plasters have shown a certain effectiveness in activation of the endogenous analgesic action, with a role in alleviate painful symptoms and improve function in rotator cuff tendinopathies, without adverse events. On the base of the safety of this technology and promising results of our study, further studies should be encouraged to confirm its effectiveness, increasing the sample number and follow up so as to demonstrate definitely that the use of technologies, on which FIT® plasters is based, may be a valid alternative as "non-medicated pain relief"
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Antibiotic-Loaded Spacer for Two-Stage Revision of Infected Total Knee Arthroplasty
No full textBackground Infection of total knee arthroplasty (TKA) is a challenge in orthopedic surgery. In literature TKA infection is classified according to the time after surgery: acute postoperative; late chronic; acute hematogenous; positive intraoperative microbiological growth. Purpose The purpose of this study is to present the results of the use of a preformed antibiotic-loaded spacer in TKA infections, treated by a two-stage revision procedure. Patients and Methods A series of 19 consecutive patients (20 knees) with a diagnosis of infected TKA were treated from January 2003 to February 2012. Two-stage reimplantation protocols were completed only in 16 patients and these data were included in the study. We lost three patients at follow-up. An antibiotic-loaded preformed articulating polymethylmethacrylate spacer was applied. Patients were observed 1, 3, and 6 months postoperatively and then yearly for clinical and radiographic examination. Results The mean American Knee Society Score improved from 68.4 preoperatively (range, from 34 to 108) to 112.7 at final follow-up (range, from 49 to 180). The pain was evaluated as part of clinical score. It improved from an average of 19.3 preoperatively (range, from 10 to 30) to 34.3 at final follow-up (range, from 10 to 50). The average range of motion improved from 40.1 degrees (range, from 6 to 90 degrees) to 79.3 degrees (range, from 45 to 125 degrees). Conclusions The use of the spacer allows obtaining a reduction of pain, an improvement of quality of life in the period of time between the two surgical stages and an easier reimplantation of TKA
Variations on the Author
Get PDF“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
Get PDFWe 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
