Active clinical trials for "Metatarsus Varus"

Prospective, multicenter, unblinded study to evaluate outcomes of the Adductoplasty™ Procedure in combination with the Lapiplasty® Procedure for patients in need of metatarsus adductus and hallux valgus correction. Up to 80 subjects will be treated in this study at up to 10 clinical sites. Patients 14 years through 65 years with symptomatic metatarsus adductus and hallux valgus will be eligible to participate based on the inclusion and exclusion criteria defined in the study protocol.

Forefoot varus is a type of foot deformities. It is asociate with subtalar joint hyperpronation, and cause too much stress over tissues around foot and lower leg during weight bearing activities. One of the common interventions for forefoot varus is to use foot orthosis with medial forefoot wedge to accommodate the forefoot deformity. Forefoot varus has been considered as an osseus deformity and caused by insufficient talar torsion during development. However, recent studies have reported forefoot varus may not be an osseus deformity. They might be a result of soft tissue adaption. For example, subtalar joint hyperpronation and ankle equinus could lead to forefoot supination/compensatory forefoot varus, which could be mistaken for osseus forefoot varus after a long period of time. If compensatory forefoot varus is caused by soft tissue adaptions, these adaptions may have a chance to reverse. Nowadays, orthoses which applying medial forefoot wedge to accommodate the deformity for forefoot varus deformity, and the other type orthoses which applying rearfoot medial wedge and arch support are both used in subject with forefoot varus deformity. However, some colleges claims that using medial forefoot wedge to accommodate the deformity of forefoot varus, the deformity may be fixed after a long-term period. However, there were no studies compare the effect of arch support orthosis that with and without medial forefoot wedge.

This is a prospective, randomized, control, open label study in which up to 50 subjects with metatarsus adductus (MTA) will be enrolled. Subjects will be treated with the standard casting or using the UNFO-s device for total time of 20 weeks.
