Outcomes of suture-button suspensionplasty for trapeziometacarpal joint arthritis

Abstract

was buddy taped to the fourth and splinted for 1 week followed by a fiberglass cast support for an additional 7 weeks. The K-wires and cast were removed at 8 weeks. The patient went on to have satisfactory aesthetic outcomes and was able to use the hand for daily activities with no limitations on 6-month follow-up. Pritsch et al. (2013) proposed a classification system to account for the various subtypes of Type A ulnar-sided polydactyly. The Type 2 group described in their publication most resembles the variant seen in our patient; however, the authors do not comment on their treatment approach. Metacarpal transposition has not been described in the management of postaxial polydactyly but is a proven salvage technique in severe hand trauma (Aliotta et al., 2018). We feel that this can be considered as a safe and effective option in selected types of complex variants of Type A ulnar-sided polydactyly.
