Adult flatfoot (progressive collapsing foot deformity) is reconstructed with a combination of procedures chosen for each patient, including a medial calcaneal osteotomy, lengthening of the lateral column (Evans) and a plantarflexing osteotomy of the medial cuneiform (Cotton). Subtalar arthroereisis is used mainly in children and adolescents with flexible flatfoot.
- OsteoSinter Evans and Cotton wedges: for lateral column lengthening or plantarflexion of the medial cuneiform in stage II adult-acquired flatfoot, supplied sterile with a single-use instrument kit.
- PitStop: a PEEK subtalar arthroereisis implant placed through the sinus tarsi.
- IOFiX TRIO: a calcaneal osteotomy plate whose surface acts as a cutting guide.
- MIS equipment: for minimally invasive calcaneal osteotomy.
