Subtalar joint arthroereisis with SILASTIC silicone sphere: a retrospective study.

Many authors have discussed the various surgical techniques of subtalar joint arthroereisis in the treatment of flexible flatfoot. Some authors advocate the use of bone grafts in the sinus tarsi to limit excessive subtalar joint pronation, while others advocate the use of endoprosthetic devices. These authors will present a retrospective study of subtalar joint arthroereisis utilizing a SILASTIC silicone sphere technique devised by the senior authors.
