Measurements were taken following canal irrigation with 1% NaOCl. The length was established using a #20 K-file attached to the holder when the display indicator reached the marks “”0.5″” (group I) or “”1″” (group II), after the meter read “”Apex.”" Then, the file was fixed in position and the teeth removed from the alginate. The apical portion of the root was shaved until the tip of the file could be seen, the distance to the apical constriction verified
by means of a stereomicroscope and the measurements compared. Statistical analysis was performed by using Student t test with the null hypothesis set as 5%. The mean positions of the file tip relative to the apical constriction were -0.23 +/- 0.39 mm and -0.42 +/- 0.45 for groups I Alvocidib ic50 and II, respectively, with no statistical difference
(P > .05). The accuracy was 90.5% and 83.78% for the Root ZX II “”0.5″” and “”1″” readings, respectively. It was concluded that the meter reading “”1″” of Root ZX II reduced the risk of working length overestimation. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: e41-e45)”
“Background: The aim of this study was to document both the short and the long-term outcomes following primary nonoperative management of isolated displaced fractures of the olecranon.
Methods: We identified, from our prospective trauma database, all patients who had been managed nonoperatively for a displaced olecranon fracture over a thirteen-year period. Inclusion learn more Bucladesine in vivo criteria included all isolated fractures of the olecranon with >2-mm displacement of the articular surface. The primary short-term outcome measure was the Broberg and Morrey Elbow Score. The primary long-term outcome measure was the Disabilities of the Arm, Shoulder and Hand (DASH) score.
Results: There were forty-three patients with a mean age of seventy-six years (range, forty to ninety-eight years) in the study cohort. A low-energy fall from a standing height accounted for 84% of all injuries, and one or more comorbidities were documented in thirty-eight patients (88%). At a mean of
four months (range, 1.5 to ten months) following injury, the mean Broberg and Morrey score was 83 points (range, 48 to 100 points), with 72% of the patients having an excellent or good short-term outcome. No patient underwent surgery for a symptomatic nonunion. At a mean of six years (range, two to fifteen years) postinjury, the mean DASH score was 2.9 points (range, 0 to 33.9 points) and the mean Oxford Elbow Score was 47 points (range, 42 to 48 points); 91% (twenty-one) of twenty-three patients available for follow-up expressed satisfaction with the result of the procedure.
Conclusions: We found satisfactory short-term and long-term outcomes following the nonoperative management of isolated displaced olecranon fractures in older, lower-demand patients.”
