CME OnDemand: 2022 AOFAS Annual Meeting-Complications of First Tarsometatarsal Joint Arthrodesis

Pdf Summary

This document discusses the complications of first tarsometatarsal joint arthrodesis, a corrective surgical technique for hallux valgus. The study was conducted by orthopedic surgeons specializing in foot and ankle surgery at UNIFESP. Sixteen patients were included in the study, and follow-up was conducted at various time intervals postoperatively. The most common complication observed was nonunion, with a rate of 25%, which is higher than rates reported in previous studies. Factors that may contribute to nonunion include vitamin D deficiency, thyroid dysfunction, and parathyroid disease. The study also explored alternative techniques to reduce the risk of nonunion, such as fragment rotation and placing the plate on the plantar aspect of the first tarsometatarsal joint. The study highlighted the importance of selecting the appropriate surgical technique for first tarsometatarsal joint arthrodesis to minimize complications and improve outcomes. However, the limitations of the study, including a small sample size and a lack of a control group, prevented the authors from drawing definitive conclusions. Further research is needed to better understand the factors influencing complications in first tarsometatarsal joint arthrodesis.
