The Helix Wire: Our experience in the treatment of humeral neck fracture.
The management of proximal humeral fractures
is still controversial and no single treatment has been
unanimously accepted. This paper focuses on displaced
two-part fractures to describe the minimally invasive fixation
device known as Helix Wire and to propose precise
indications for its use, partly on the basis of our previous
study of its mechanical properties. Thirty patients with
nondisplaced and displaced humeral neck fractures were
treated with implantation of a Helix Wire between
January 2005 and September 2005. Clinical and radiographic
follow-up was carried out at 1, 2, 6 and 12
months. Clinical and functional assessment was performed
using the Constant-Murley score. The results at 1
year after surgery were excellent in 7 cases (23.3%), good
in 14 cases (46.6%), fair in 8 cases (26.6%) and poor in 1
case (3.3%). On the basis of our precise indications, elderly
patients with nondisplaced or displaced two-part
fractures of the proximal humerus may achieve good
results with minimally invasive implantation of the Helix
Wire
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
