Do elective implant removal in symptomatic patients after internal fixation of proximal humerus fractures improves clinical outcome?
Symptomatic patients after locked plate osteosynthesis for proximal humerus fractures showed statistically significant improvement of the Constant score after implant removal.
Pellet propulsion in the guinea pig's distal colon depends on nitric oxide to provide appropriate balance of force between proximal and distal contraction, resulting in pellet propagation toward the anus. CM contracts both proximal and distal to the pellet, and the polarity of pellet progression depends on the balance of the two forces.
