The purpose of this study was to evaluate the long-term function of the LaPorta design great toe implant. Eight cases were evaluated preoperatively and on a short-term (mean = 3.6 months) and a long-term basis (mean = 20.5 months) postoperatively. Findings of clinical importance included decreased hallux dorsiflexion and radiographic evidence of hyperostosis formation at the implant hinge. However, all of the patients studied were satisfied with their results.
