Geographical differences in carpometacarpal joint osteoarthritis treatment of the thumb: A survey of 1138 hand surgeons from the USA and Europe.

BACKGROUND: Carpometacarpal osteoarthritis of the thumb (CMC OA) is treated with various therapeutic approaches. However, the literature remains inconclusive regarding the ideal procedure for each disease stage. In this study, we assessed the international application of surgical treatment options including CMC I implants and non-surgical treatment options for CMC OA depending on the disease stage, with a strong focus on the detection of geographical disparities. METHODS: We conducted a large international online survey with members of hand surgical societies of the International Federation of Societies for Surgery of the Hand (IFSSH). The first part of the survey asked about general therapy options of CMC OA depending on the severity of the disease, whereas the second part specifically dealt with the use of prostheses. RESULTS: We could include 10 of 56 IFSSH member societies (6807 surgeons) and received answers from 1138 members (16.7%). Significant differences were detected in an increased use of corticosteroid injections in the USA, and a growing frequency of fat injections in Europe. Regarding use and frequency of the resection arthroplasty, we found similar results in all participating countries. Prosthetic implantation showed a significant difference between the USA and Europe, with far larger numbers stated by European hand surgeons. CONCLUSION: CMC OA is treated differently in the participating countries depending on the stage of the disease. We give an insight into geographical differences in treatment paradigms, with corticosteroid injections being more prevalent in the USA, and prosthesis implantation being more frequently chosen in the selected European countries.      «
