It appears the suture-button behaves similarly to the syndesmotic screw in the syndesmotic rupture injury model tested. Clinical trials are needed to determine how the device performs in vivo.
The aim of the study was to investigate the effect of smoking on the operative treatment of established nonunion of the carpal scaphoid. Case notes and radiographs of patients undergoing bone grafting and screw fixation of scaphoid non-unions were reviewed. There were 34 patients that had undergone 37 operations for established non-union of the carpal scaphoid bone. There were two female patients, and the average age was 26.8 years (range 13.4 years to 52.9 years). The median delay to operation was 11.9 months. The overall success rate of the operation (internal fixation and autologous bone grafting) was 59.5% (22/37), but there was a significant association between non-union and smoking (P=0.02 for Fisher's exact test). In non-smokers (n=17) the success rate was 82.4%, but this dropped to 40.0% among smokers (P<0.01). We concluded that smoking was significantly associated with failure of operative treatment of established non-union of the scaphoid bone. Résumé Le but de cette étude est d'évaluer les effets de la cigarette dans le traitement chirurgical des pseudarthroses du scaphoïde carpien. Méthode nous avons revu les dossiers cliniques et radiographiques des patients devant bénéficier d'une greffe et d'un vissage pour une pseudarthrose du scaphoïde. Résultats : 34 patients ont bénéficié de 37 opérations pour une pseudarthrose du scaphoïde carpien. Il s'agissait de deux sujets de sexe féminin, les autres patients étant de sexe masculin, la moyenne d'âge étant de 26,8 ans (13.4 à 52.9). Le délai moyen de réintervention a été de 11.9 mois. Le taux de bons résultats (fixation interne et greffe autologue) a été de 59.5% (22/37) mais il a été mis en évidence une relation significative entre le taux de pseudarthrose et le nombre de sujets fumeurs (p=0.02 thèse de Fisher). Chez les sujets non fumeur, n=17, le taux de succès a été de 82.4%, alors qu'il n'est que de 40% chez les fumeurs. En conclusion, la cigarette peut être associée avec un taux d'échec du traitement chirurgical des pseudarthroses du scaphoïde.
BACKGROUND AND PURPOSE:Currently, the effect of the volume of cement used during sacroplasty on the restoration of pelvic strength and stiffness is unknown. The purpose of this study was to measure that effect in a sacral insufficiency fracture model.
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.
