The abstract you quoted is on the original Dornier study. The final paper was published in May 2004 Foot and Ankle International.
The Dornier study was a multi center, double blind, placebo controlled study that involved 150 patients. The active group consisted of 76 patients. The study followed these patients for a year post treatment. Many patients were lost to follow-up. In this study, the one year results were based on reports from 50 of the original 76 patients in the active group. Twenty-six (26) patients were lost to follow up.
In order to be completely accurate, the success results should qualified by the number of patients reporting success and should probably read: 'At one year 50 members of the active group reported 94% success at 12 months post treatment'. It is important to qualify the data since the study did not determine whether the other 26 patients experienced success or failure.
This limitation of the study conclusion was discussed in detail on this site last year.

Good point. It was based on the patients that reported back after one year. Do you know how many out of the active patients reported back after one year in the ossatron one year follow up study.
Another question that came to mind is out of the patients that didn't follow up what were their scores at the twelve week evaluation or the last time that they were evaluated.

Variability in results can vary by the way one defines a cure. When Ossatron was the only act in town for a while, Bill Fallon,MD, the local owner stated that he defines success as a patient reaching pain level 4. Very few of my patients (speaking of may practice) would accept that.
