Post-traumatic total wrist arthrodesis: Satisfaction study of 42 cases at a mean 97 months’ follow-upArthrodèse totale de poignet post-traumatique : étude de satisfaction à propos de 42 cas avec un recul moyen de 97 mois

International audienceIntroductionTotal wrist arthrodesis is effective in reducing pain in osteoarthritic wrist, but at the cost of range of motion. The aim of the present study was to assess patient satisfaction after post-traumatic total wrist arthrodesis, complications and risk factors.HypothesisPost-traumatic total wrist arthrodesis provides a high rate of satisfaction.Patients and methodsA single-center retrospective observational satisfaction survey was carried out for the period 2005–2020 by telephone interview.ResultsForty-two post-traumatic dorsal plate total wrist arthrodeses were included. Mean follow-up was 97 months. Total arthrodesis achieved a mean 75% reduction in pain, with good functional results (QuickDASH: 23 ± 9.1 [11–42]) and satisfaction (83% of patients very satisfied or satisfied). Seventy-two percent of patients continued in their previous work. The complications rate was 48%. Twenty patients had complications, including 14 (33%) requiring surgical revision. Thirteen patients (31%) had hardware removed due to plaque discomfort and 1 due to bone and joint infection. Seven patients showed CRPS.ConclusionTotal wrist arthrodesis provided good results in terms of pain relief and satisfaction, at the cost of loss of motion. It is a reliable surgical technique, with an essential place in the therapeutic algorithm for post-traumatic osteoarthritic wrist, particularly in manual workers

Prothèse totale d'épaule en France : analyse des tendances entre 2009 et 2019 et projection à l'horizon 2070

International audienceBackground: Over the past decades, total shoulder arthroplasty (TSA) procedures have steadily increasedin the United States and Europe. In France, the number of shoulder surgeries rose by 24.5% between 2012and 2018, but no study has yet analyzed TSA trends based on patient characteristics. Therefore, the aim ofour study was to use the French healthcare database to (1) analyze growth trends based on the patient’ssex, age, and comorbidity profile and (2) estimate the most appropriate incidence rate (IR) projections tothe year 2070.Hypothesis: We hypothesize that in France, the upward trends are different for each sex and age group.Materials and methods: This study was conducted in France from 2009 to 2019 based on the Frenchhealthcare database (SNDS), which contains all nationwide procedures. Patients were analyzed by sex,age group (< 65 years, 65–74 years, ≥ 75 years), and comorbidity profile (4 levels). IR trends per 100,000population were inferred by patient age, sex, and comorbidity using data from the French hospital discharge database (PMSI) and population forecasts and censuses from the French National Institute ofStatistics and Economic Studies (INSEE). Linear, Poisson, logistic, and Gompertz projection models werecreated to forecast IRs to the year 2070.Results: Between 2009 and 2019, there was a sharper increase in IR in males (+155%; from 6.0 to 15.3)than in females (+118%; from 16.2 to 35.3) across all age groups. This increase was most significant inthose younger than 65 years (+112%; from 2.3 to 4.9), in both males (+129%; from 2.1 to 4.8) and females(+99%; from 2.5 to 5.0). From 2012 to 2019, the proportion of patients with mild comorbidities increasedby +92% (from 5,435 to 10,410 TSAs, i.e., from 56% to 61% of total procedures), unlike the other comorbidityprofiles. All the projections modeled the data from 2009 to 2019 with minor deviations. However, thelogistic projection was the most likely, with a 45% increase in the IR for the overall population by 2070(from 17,175 to 25,338 TSAs), which will start to plateau in 2050.Conclusion: The IR has risen sharply in the overall population, as in all age, sex, and comorbidity categories,with the most significant growth seen in the < 65 and 65–74 age groups and a shift toward patients withmilder comorbidities. According to our projections, the IR will continue to be more significant in olderpatients, except for males, for whom the IR for those 65 to 74 years old will exceed that of those 75 andolder around 2030. In the longer term, the IRs follow a logistic trend, reaching a plateau around 2050.Therefore, an increase in healthcare burden is to be expected to meet the growing demand for TSAs.Level of evidence: IV; Descriptive epidemiological study
