NCT ID: NCT00949897 Withdrawn - Clinical trials for Adult Acquired Flatfoot

Comparison Study of Biofoam Porous Metal Versus Allograft to Treat Adult Acquired Flatfoot

Start date: March 2009
Phase: Phase 4
Study type: Interventional

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.
