Short term results of anatomic stemless shoulder replacement with peripheral neck fixation

Background: Most of the current stemless implants are using a central neck fixation design. Easytech Stemless replacements (FX Solutions®, Viriat, France) were developed promoting the idea of peripheral fixation of the stemless implant. The aim of this study was to analyze clinical and radiological results of this stemless TSA implanted for osteoarthritis (OA). Methods: A retrospective study of patients who received TSA with the Easytech® Anatomical Shoulder System (FX Solutions®, Viriat, France) for OA was completed at five clinical sites. Preoperative and minimum 2 year follow-up Constant Scores and X-rays were evaluated. Two independent orthopedic surgeons analyzed X-rays to assess anatomy reconstruction and component migration. Revisions and serious adverse effects were reviewed. Results: 129 patients were analyzed with an average follow-up of 37.47 months (24-54). Seven patients had a revision surgery and one of these resulted in the removal of the Anchor Base. The postoperative Constant Scores showed significant improvement with a mean raw Constant Score of 73.78 (38.0-100.0, mean increase 40.96, P < .0001) and mean adjusted Constant Score of 99.14 (42.20-133.30, mean increase 55.68, P < .0001). Radiographic review demonstrated that no modification of the center of rotation (COR) at minimum 24 months was greater than 3 mm and in comparison to preoperative radiographs, restoration of COR was lateralized in 25% of the cases, medialized in 61.5% and 13.5% had no change in COR. The mean value of the cervico-diaphyseal angle was 130.2° (114; 149) at 3 weeks and 129.9° (113.5; 144.0) at 2 years, demonstrating no significant difference (P = .16). 36 patients (35%) had calcar remodeling. Univariate and multivariate logistic regression found no significant factor, which was associated with the variation of the cervico-diaphyseal angle over time, center of rotation, calcar remodeling, or final Constant Score. The Walch B2 and C glenoid subset of patients (n = 13) had overall survival rate of 90.9% [95% CI 75.4-100.0] vs. 98.0% [95% CI 95.3-100.0] in other glenoid types (P < .01). Walch B2/C patients were 4.44 [95% CI 1.13, 17.6] times more likely to have a Constant Score <85 (P = .03). Conclusions: The peripheral fixation of the Easytech® Anatomical Shoulder System for OA provides excellent clinical results and imaging stability at minimum two year follow-up. Elderly age, gender and BMI do not affect the stability

Infliximab versus adalimumab in the treatment of refractory inflammatory uveitis: Multicenter study from the french uveitis network

International audienceOBJECTIVES: To analyze the factors associated with response to anti-TNFα and to compare the efficacy and safety of infliximab (IFX) and adalimumab (ADA) in patients with refractory non infectious uveitis.METHODS: Observational multicenter study including 160 patients [median age of 31 [21-42] years with 39% of men] with refractory uveitis treated with anti-TNFα [IFX 5mg/kg at weeks 0, 2, 6 and every 5-6 weeks (n=98) and ADA 40mg/14days (n=62)]. Factors associated to complete response were assessed in multivariate analysis. Comparison between efficacy and safety of IFX and ADA was performed using a propensity score approach accounting for baseline characteristics.RESULTS: Main etiologies of uveitis included Behçet's disease (36%), juvenile idiopathic arthritis (22%), spondylarthropathies (10%) and sarcoidosis (6%). The overall response rate at 6 and 12 months was of 87% (26% of complete response) and 93% (28% of complete response), respectively. The median time to complete response was 2 (0-12) months. In multivariate analysis, Behçet's disease (SHR= 2.52 [1.35-7.71], p=0.004) and a number of uveitis flares before anti-TNFα greater than 5 (HR=1.97 [1.02-3.84], p=0.045) were associated with complete response to anti-TNFα. Side effects were reported in 28% of patients, including 12% of serious adverse events. IFX and ADA did not differ significantly in terms of occurrence of complete response (SHR=0.65 [0.25;1.71], p=0.39), serious side effects (SHR= 0.22 [0.04-1.25], p=0.089) or event free survival (SHR=0.55 [0.28;1.08], p=0.083).CONCLUSIONS: Anti-TNFα are highly effective in refractory inflammatory uveitis. Behçet's disease is associated with increase odds of response. IFX and ADA seem equivalent in terms of efficacy. This article is protected by copyright. All rights reserve

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
