We have retrospectively reviewed the clinical and radiological results in 204 consecutive adult patients who had surgical correction of 70 late post-traumatic pelvic nonunions and 134 malalignments. The deformed pelvises were subdivided into united (true), unstable, ununited, and partially stable malalignments with heterotopic bone. The principal complaints were of pain, pelvic instability, sitting imbalance, and apparent limb-length discrepancy. After surgery, 195 patients (96%) achieved a primary union and 144 (71%) had slight, intermittent or no pelvic pain, while pelvic instability was entirely eliminated. Overall, 131 patients (64.2%) were extremely satisfied, 58 (28.4%) were satisfied and 15 (7.4%) were unsatisfied. After reconstruction of the malaligned pelvises, 67 results (50%) were anatomical, 47 (35%) were satisfactory and 20 (15%) were unsatisfactory. For a pelvic nonunion with local osteopenia and malalignment, stabilisation of all three pelvic columns is recommended. True pelvic (united) malunions were the most satisfactorily realigned and had the fewest complications. Ununited and unstable malalignments, especially those with heterotopic bone, had the poorest corrections and the most neurological complications. A therapeutic alternative, by the local resection of a symptomatic bony prominence, and fixation in situ of a posterior pelvic nonunion, gives highly effective symptomatic relief with fewer complications. Despite this, many patients had persistent low back pain.
Uterus didelphys is rare and sometimes not even diagnosed. We report a case of didelphys uterus in a 26-year-old pregnant lady who previously had three successful pregnancies with previous one C-section and remained undiagnosed till she presented to us as ruptured uterus. This case report aimed to summarize the clinical characteristics and perinatal outcome of VBAC in pregnancy with didelphys uterus and history of previous cesarean section.
Traditional mechanical methods of retaining restorative materials have been replaced to a large extent by tooth conserving adhesive restorative techniques. Bonding techniques allow more conservative tooth preparation. Less reliance on macromechanical retention and less removal of unsupported enamel because adhesives have been evolving, so rapidly for the last few years, as the timing is right for evaluating the clinical status of present day adhesives. The purpose of this article is to provide a concise, comprehensive and updated classification of dentin bonding agents. Current products are highlighted to improve clinical use and performance of the materials.
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.
