No full textCases: We present the cases of two adult male patients with painfully delayed union of proximal tibia diaphyseal fracture after intramedullary nailing. Patients underwent to nail dynamization and Poller blocking screw augmentation at 3 and 5 month, respectively, after the index surgery. Both patients were pain-free after the surgery and bone-union were radiographically evident after 3 months. At 12-month follow-up, patients returned to their previous activities. Conclusions: Although nail dynamization is the choice treatment to obtain fracture compression for delayed union of tibial shaft fractures, augmentation with Poller blocking screw could provide additional mechanical stiffness in unstable supra-isthmic shaft fractures of the tibia and favour bone union.

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
