Biomechanical Comparison of Cadaveric and Commercially Available Synthetic Osteoporotic Bone Analogues in a Locked Plate Fracture Model Under Torsional Loading.

Objectives: Biomechanical studies of osteoporotic bone have used synthetic models rather than cadaveric samples because of decreased variability, increased availability, and overall ease of the use of synthetic models. We compared the torsional mechanical properties of cadaveric osteoporotic bone with those of currently available synthetic osteoporotic bone analogues.

Methods: We tested 12 osteoporotic cadaveric humeri and 6 specimens each of 6 types of synthetic analogues.

Extensile surgical exposures of the radius: a comparative anatomic study.

Purpose: To evaluate and compare exposures of the radius using 3 surgical approaches. Our hypotheses were that the anterior flexor carpi radialis approach allows greater exposure of the distal radius than does the volar-ulnar approach, and the extensile flexor carpi radialis approach allows comparable proximal and midshaft exposure of the radius compared with the dorsal Thompson approach.

Methods: We performed anterior and dorsal exposures of the radius on 10 matched pairs of cadavers (20 forearms) randomly assigned to 1 anterior and 1 dorsal approach.

Investigation of multiligamentous knee injury patterns with associated injuries presenting at a level I trauma center.

Objectives: To characterize multiligamentous knee injury patterns and describe associated morbidities.

Design: Retrospective.

Setting: Level I trauma center.
