Treatment of severely comminuted intra-articular fractures of the distal end of the radius by open reduction and combined internal and external fixation.

Background: Severely comminuted AO type-C3 intra-articular fractures of the distal end of the radius are difficult to treat. Failure to achieve and maintain nearly anatomic restoration can result in pain, instability, and poor function. We report the results of a retrospective study of the use of a standard protocol of open reduction and combined internal and external fixation of these fractures.

MRI of fractures of the distal radius: comparison with conventional radiographs.

Objective: To compare the evaluation of fractures of the distal radius with MRI and conventional radiographs. To demonstrate the ability of MRI to detect unsuspected soft tissue derangement accompanying this common injury.

Design And Patients: Twenty-one consecutive inpatients admitted following fracture of the distal radius underwent preoperative evaluation with both conventional radiographs and MRI.

The preoperative angiogram as a predictor of peripheral vascular runoff.

The preoperative angiogram is widely used as a means of assessing peripheral vascular runoff before bypass grafting, but the correlation between preoperative angiographic findings and actual measurements of peripheral vascular resistance has not been adequately examined. To test this correlation, we first devised a simple technique for measuring peripheral resistance and validated it in five dogs. Increases in peripheral resistance were artificially produced by temporarily occluding either the deep or superficial femoral artery or by intravenous administration of phenylephrine hydrochloride, a vasoconstrictor.
