KNEE LIGAMENT INJURIES IN VOLLEYBALL PLAYERS
No full textThe authors report a series of 52 cases of serious knee ligament injuries in volleyball players. The most frequent mechanism of injury was landing from a jump in the attack zone. Women were more affected than men. Injuries were more frequent during games than training. Volleyball must then be considered among high-risk sports according to the frequency and gravity of our surgical findings. Results are similar to those obtained in athletes in other sports who underwent the same surgical procedure

Third-degree lesions of the external compartment of the ankle: Results of conservative treatment
No full textAnkle sprains are one of the most common lesions of the musculoskeletal system. In some sports they are the most common reason that athletes seek medical care. For this reason many publications are dedicated to this subject, and specifically to the treatment of lesions of the external compartment, which account for about 85% of all ligamentous lesions of the ankle (O'Donoghue, 1958). The treatment of these lesions is very controversial. Some orthopedists propose early surgical treatment to restore normal healing with minimal functional lengthening. Others favor conservative treatment, while still others recommend functional treatment with the objective of accelerating the recovery of proprioceptive reflexes affected by the ligamentous lesion as well as stimulating healing by movement. The authors' diagnostic and therapeutic approach to lesions of the external compartment of the ankle is explained with special reference to lesions in athletes, who must be guaranteed perfect joint stability in order to tolerate the intense stress of sports activity without danger of relapse
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
Regeneration of the Semitendinosus Tendon Harvested for Anterior Cruciate Ligament Reconstruction. Evaluation Using Ultrasonography
Full text linkIn a prospective study, 40 consecutive patients who underwent anterior cruciate ligament reconstruction with doubled semitendinosus and gracilis tendon autografts were examined pre- and postoperatively by ultrasound to investigate the anatomy of the donor site before and after the harvest of the tendons. The patients underwent ultrasonography at 2 weeks and 1, 2, 3, 6, 12, 18, and 24 months postoperatively. A total of 298 postoperative sonographic evaluations were performed. The semitendinosus tendon was imaged in the sagittal and axial planes: structure and margins were evaluated with the sagittal views; thickness and width were measured with the axial views. In all cases the following sequence of healing was documented: 2 weeks after surgery the semitendinosus tendon site was occupied by an area of increased thickness and decreased echogenicity, suggesting the presence of traumatic edema of the soft tissue surrounding the tenotomy. At 1 month, an irregular hypoechoic structure appeared in a near-anatomic position; at 2 months after surgery, thickness, width, and cross-sectional area of this structure were significantly greater than preoperatively. The amount of regenerated tissue increased up to that seen in the tissue of the 6-month examinations, which also showed a more uniform echostructure. The scans performed at 1 year showed distinct edges and reduction in thickness and width. At 18 and 24 months the echogenicity of the structure occupying the donor site was very similar to that of the normal semitendinosus tendon. However, this structure was clearly identified about 4 cm proximal to the pes anserinus, revealing a more proximal insertion of the regenerated semitendinosus tendon
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
