- چکیده:
- چکیده انگلیسی: For scientific and professional growth of teachers and students in teacher-training centers Access to information and communication technology skills And especially the Internet Considered As an inevitable necessity The present study With reference to the theoretical evidence and Library Studies Is discussed, First to review potential applications of this technology and The most important factors in increasing teacher training centers Self -Efficacy students and teachers The use of the Internet. Rapid development of ICT in various aspects of life and including education, a large effect on the left. So, Looking at developments Examined, changes were made to the accuracy Education to keep up with rapid changes There has been a proliferation of ICT Requires teachers who are qualified in this respect. This goal requires that the teacher in the Teacher training centers country, Experience with ICT-based curriculum And acquire attitudes and knowledge needed to use it Hence offered Courses introduction and application of information and communication technology Is necessary the student curriculum teacher training centers.

- چکیده:
- چکیده انگلیسی: Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of the
magnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this study
aimed to investigate whether MRI improved the management of glomus tumors.
Methods: In total, 87 patients with a histologically confirmed glomus tumor were treated over a 25-year period and
analyzed retrospectively. Multivariable logistic regression analysis was used to evaluate the independent predictors of
an MRI request during the management of glomus tumors.
Results: According to the results, the patients who were treated by orthopaedic surgeons were more likely to have an
MRI during the management of a glomus tumor.
Conclusion: The role of an MRI during the management of a glomus tumor is unclear. Orthopaedic surgeons are
more likely to request an MRI. Furthermore, visible lesions with characteristic symptoms probably do not benefit
from MRI. However, it may help to be sure that the highest-quality MRI is used with the best possible coil for the
finger.

- چکیده:
- چکیده انگلیسی: Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperatively
on three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of the
full length of the femur or as the anatomical axis of the distal half of the femur, which may result in different angles
in some cases. During TKA, the anatomical axis of the femur is determined by intramedullary femoral guides, which
may follow the distal half or near full anatomical axis, based on the length of the femoral guide. The aim of this study
was to compare using the anatomical axis of the full length of the femur versus the anatomical axis of the distal half of
the femur for measuring VCA, in normal and varus aligned femurs. We hypothesized that the VCA would be different
based upon these two definitions of the anatomical axis of the femur.
Methods: Full-length weight bearing radiographs were used to determine three-joint alignment in normal aligned
(Lateral Distal Femoral Angle; LDFA = 87º ± 2º) and varus aligned (LDFA >89º) femurs. Full-length anatomical axismechanical
axis angle (angle 1) and distal half anatomical axis-mechanical axis angle (angle 2) were measured in
all subjects by two independent orthopedic surgeons using a DICOM viewer software (PACS). Angles 1 and 2 were
compared in normal and varus aligned subjects to determine whether there was a significant difference.
Results: Ninety-seven consecutive subjects with normally aligned femurs and 97 consecutive subjects with varus
aligned femurs were included in this study. In normally aligned femurs, the mean value of angle 1 was 5.05° ± 0.76°
and for angle 2 was 3.62° ± 1.19°, which were statistically different (P= 0.0001). In varus aligned femurs, the mean
value of angle 1 was 5.42° ± 0.85° and for angle 2 was 4.23° ± 1.27°, which were also statistically different (P=
0.0047).
Conclusion: The two different methods of outlining the anatomical axis of the femur lead to different results in
both normal and varus-aligned femurs. This should be considered in determination of the valgus cut angle on preoperative
radiographs and be adjusted according to the length of the intramedullary guide.- انتشار مقاله: 15-07-1396
