Adult Acquired Flatfoot Clinical Trial
Official title:
A Randomized, Prospective, Controlled Trial for Lateral Column Lengthening in Adult Acquired Flatfoot Using Biofoam Porous Metal Compared With Allograft
The purpose of this study is to compare the clinical and radiographic outcomes of a
randomized, consecutive series of adult patients, with an acquired flatfoot, treated with a
lateral column lengthening using an allograft bone wedge versus a titanium porous metal
implant (Biofoam, Wright Medical).
Null hypothesis: At six months postoperatively, there is no difference in the degree of
correction as measured by the talonavicular coverage angle between patients randomized to
allograft and Biofoam.
Alternative hypothesis: At six months postoperatively, the degree of correction as measured
by the talonavicular coverage angle will be less in patients randomized to allograft than
the degree of correction in patients randomized to Biofoam.
