The compression obtained with external anchorage in the anterior and posterior part of the pelvic girdle has been studied with a measuring device in the sacroiliac joint and and the symphysis of a specimen pelvis. Two models of external frames were tested, in both of which anchorage to the pelvic bone was brought about with 3 pins inserted in the iliac crests. ⋯ This mounting afforded good stability of the detached hemipelvis. The trapezoid compression frame is recommended as an alternative to conventional methods of treating unstable fractures and dislocations of the pelvic girdle.

A case of intercostal pulmonary hernia following blunt trauma to the chest wall is reported. This type of hernia is a benign disorder. Although most lung herniae need operative treatment, it is reasonable to wait for spontaneous regression.
