A biomechanical analysis of plate fixation using unicortical and bicortical screws in transverse metacarpal fracture models subjected to 4-point bending and dynamical bending test.

In the published literature there are controversial data to the biomechanical stability of monocortical comparing to the bicortical fixation of metacarpal fractures. The aim of this study was to compare the biomechanical stability of monocortical and bicortical locking osteosynthesis in quasi-static and dynamic 4-point bending tests of composite third metacarpal bone (4th Gen third metacarpal, Sawbones, Malmö, Sweden) fixed with 7-hole locking plate (XXS System, Biotech-Ortho, Wright, Memphis, TN). The tests to determine quasi-static yield and bending strength as well as fatigue strength were conducted in 4 groups of 10 samples after creating standardized mid-shaft transverse osteotomies using a diamont belt grinder (0.

Prophylactic antibiotic therapy after inhalation injury.

Objective: Inhalation injury is suspected in patients with facial and neck burn-injuries and in patients who suffered burns in an enclosed space. Inhalation injury is associated with a disappointingly high morbidity and mortality in spite of advances in diagnostics and therapy.Prophylactic antibiotic therapy in patients with diagnosed inhalation injury is still a controversial subject.
