Ankle arthroplasty is a viable treatment option for end-stage ankle arthritis and has shown improvements in pain relief, motion, as well as function and gait. Newer generation total ankle prostheses have improved instrumentation and surgical techniques, as well as minimal bone resection on both the tibia and talus. The purpose of this systematic review was to determine the short-term clinical success of the INFINITY total ankle, including the common complications and rate of revision with this prosthesis. We performed a systematic review of electronic databases that included reported complications and revisions using this prosthesis. Complications were recorded according to the Glazebrook classification. Six total published studies with clinical outcomes and complications and 432 prostheses were included. The weighted mean follow-up was 24.5 months and weighted mean patient age was 62.3 years. There were 43 (10.0%) total complications—9 low grade, 16 medium grade, and 18 high grade. There were 26 total revision procedures (6.0%). Revisions were mostly performed for deep infection, aseptic loosening, and subsidence. When including deep infections, the overall implant survivorship was 94%. When excluding the 8 deep infections requiring revision, implant survivorship was 96%. The INFINITY has acceptable short-term complication and revision rates. This fourth-generation prosthesis compares to prior reported studies with earlier generation ankle implants in the short term.

Metatarsus adductus is a structural deformity that may be associated with hallux valgus and that may lead to metatarsal pain and functional abnormality of the foot. Correcting hallux valgus is complicated in these cases because of the deviation in adduction of the lesser metatarsals, especially the second metatarsal that occupies the first intermetatarsal space. We report the case of a 49-year-old man who underwent a scarf osteotomy in the first metatarsal, shortening and abductor oblique distal osteotomies of the lesser metatarsals, and arthrodesis of the central toes with Z-lengthening of the capsule and long extensor tendons of the toes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
