Safety of the application of Rigidfix cross-pin system via different tibial tunnels for tibial fixation during anterior cruciate ligament reconstruction.

Background: We investigate the safety of the application of the Rigidfix cross-pin system via different tibial tunnels in the tibial fixation during anterior cruciate ligament (ACL) reconstruction.

Methods: Five adult fresh cadaver knees were fixed with the Rigidfix cross-pins in the tibial fixation site during ACL reconstruction. Two different tibial tunnel groups were established: in group A, the tunnel external aperture was placed at the 25° angle of coronal section; in group B, the tunnel external aperture was placed at the 45° angle of coronal section.

Volar locking plate versus external fixation for the treatment of unstable distal radial fractures: a meta-analysis of randomized controlled trials.

Background: The choice between volar locking plates (VLP) and external fixation (EF) for unstable distal radius fractures have not reached a consensus. The meta-analysis of randomized controlled trials was performed to compare VLP with EF to determine the dominant strategy.

Materials And Methods: Meta-analysis was performed with a systematic search of studies conducted by using the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases.

2,2,2-Trifluoro-N-(4-methyl-2-oxo-2H-chromen-7-yl)acetamide.

In the title mol-ecule, C(12)H(8)F(3)NO(3), the trifluoro-methyl group is rotationally disordered over three orientations in a 0.5:0.3:0.

7-Diethyl-amino-2-oxo-2H-chromene-3-carbaldehyde.

In the title compound, C(14)H(15)NO(3), all non-H atoms except for those of the methyl and the disordered ethyl groupare approximately co-planar, the largest deviation from the mean plane being 0.0223 (13) Å at the N atom. In the crystal, the packing of mol-ecules through weak inter-molecular C-H⋯O hydrogen-bonding inter-actions leads to the formation of layers parallel to bc plane.

A comparison of fructosamine and HbA1c for home self-monitoring blood glucose levels in type 2 diabetes.

Background: Optimal glycemic control is believed to be essential in patients with diabetes to minimize any long-term complications. Measurement of the levels of glycated protein, such as fructosamine and glycated hemoglobin (HbA1c), is the most reliable method for assessing a period of glycemic control. This prospective study was performed to investigate whether fructosamine or HbA1c could provide a reliable index of glycemic control in type 2 diabetes.
