In patients with fixed cavovarus feet, both SMOT and LCOT provided equally good redistribution of elevated ankle joint contact forces. Increasing the amount of displacement did not seem to equally improve the joint pressures. The site of osteotomy could therefore be chosen on the basis of surgeon's preference, simplicity, or local factors in case of more complex reconstructions.
Pelvic measurements in a group of 115 women delivering in breech presentation were compared with those in a group of 100 delivering in cephalic presentation. The average pelvic measurements were all a few mm larger in the breech cases and the average sum of the outlet diameters was significantly larger. Pelvic disproportion was not more common in breech presentation and no support was found for the theory that large pelvic measurements predispose to breech presentation. The small differences found are attributed to the moulding of the pelvis occurring during parturition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
