    Abstract Aim: The main objective of this study was to estimate the carbon impact of arthroscopic rotator cuff repairs in France. The secondary objective was to assess the effectiveness of the following measures in reducing the carbon footprint associated with this technique: outpatient treatment, arthroscopic water filtration, surgery under locoregional anesthesia.
    Hypothesis: The hypothesis was that the carbon footprint could be significantly improved with the implementation of these three procedures.
    Methods: A continuous series of 26 patients who underwent surgery for a rotator cuff tear involving only one tendon between November 2020 and April 2021 were included. The evaluation protocol consisted of three parts: 1/ use of volatile anesthetic agents; 2/ electrical consumption linked to the procedure; 3/ emissions related to patient and staff travel, delivery of implants and waste management. Another series of 26 patients operated between November 2018 and April 2019 who had none of these three factors were matched.
    Results: The carbon impact of arthroscopic repair of the rotator cuff was estimated at 334.61±18.82kgCO
    Conclusion: Performing surgery under locoregional anesthesia, on an outpatient basis with water purification, reduces the carbon impact of arthroscopic rotator cuff repair by more than 12%.
    Level of evidence: III, retrospective case control.

    Abstract The use of negative pressure therapy for digital skin loss is uncommon. A reason for this is the difficulty of applying dressings to the hand, which are often difficult to seal. However, negative pressure therapy offers some benefits, especially when associated with local infection. We present a nonspecific, simple and original technique using a Pico negative pressure dressing that may be easily applied in daily practice.

    Abstract Objective: The purpose of our study was to compare the cost of surgical site skin preparation using ChloraPrep™ (2% chlorhexidine gluconate [CHG] and 70% isopropyl alcohol [IPA]) with skin cleansing using Betadine® Surgical Scrub and Betadine® 5% solution (povidone-iodine [PVI]) in total hip arthroplasty (THA).
    Hypothesis: The hypothesis was that the ChloraPrep™ skin disinfection protocol reduces the cost of perioperative antisepsis.
    Methods: A prospective database was created for all THAs performed at our university hospital between November 1st, 2020, and December 31st, 2020. Each surgeon was randomly assigned one type of antiseptic prior to the start of the study: one surgeon to the ChloraPrep™ group and one to the Betadine® group. In both groups, the enrollment stopped at the 15th patient. The costs related to consumables, waste disposal, and operating room occupancy time of each protocol were then assessed for each patient.
    Results: The mean duration of the ChloraPrep™ protocol was 3.5±0.3minutes compared to 13.5±0.9minutes for the Betadine® protocol. The overall cost of a surgical site skin preparation involving all three steps was on average €46.8±4.2 for the ChloraPrep™ group compared to €155±10.9 for the Betadine® group (p<0.0001).
    Discussion: Not only is the effectiveness of ChloraPrep™ already recognized but it also appears to have health economic benefits. However, further studies are needed to confirm this finding.
    Level of evidence: III, case control study.

    Abstract Dynesys® is a dynamic device used for posterior stabilization of the lumbar spine. The objective of this study was to analyze the clinical and radiological outcomes at a 2-year minimum follow-up. In this retrospective study, patients operated between 2009 and 2016 with Dynesys® stabilization were included. 5 different etiologies were included: disc herniation, lumbar stenosis, revision for adjacent seg- ment disease (ASD), spondylolisthesis, and scoliosis. Clinical and radiological evaluations were performed. Postoperative complications and revisions were recorded. 136 patients were included: 34 for lumbar spinal stenosis, 19 for disc herniation, 29 degenerative spon- dylolisthesis, 41 revisions for ASD, and 13 scoliosis. Mean age was 64.8. Average clinical follow-up was 46 months. Postoperative clinical results showed a mean lumbar VAS of 3.07, a mean radicular VAS of 3.01 and an ODI score of 31.8%. The ASD rate was 16.2%, and overall revision rate was 11.8%. 2 cases (1.5%) of screw loosening were identified. Clinical outcomes, ASD rate and revision rate were more favorable in the spondylolisthesis and disc herniation groups. This study has one of the largest Dynesys® cohort in literature. Spinal dynamic stabilization by Dynesys® presents good long-term clinical and radiological out- comes with a lower rate of complications than pre- viously published cohorts and lumbar fusions. Best indications seem to be degenerative spondylolisthesis.

    Abstract Purpose: The objective of this study was to determine the reasons for complaints and describe the judicial means upstream of France's courts following arthroscopy.
    Methods: This is a retrospective observational study including all compensation records related to arthroscopic surgery, collected from the two leading French insurance organizations: MACSF and Branchet companies, from 2014 to 2018. Three medical experts performed the protocol and analysis.
    Results: Finally, 247 procedures were included. The most common motives were: the appearance or persistence of pain (43.7%), postoperative infection (29.1%), technical errors (10.5%), nerve damage (5.7%), arterial lesions (2.8%), side errors (2.4%). Knee arthroscopies were more at risk of legal action for infection (p = 0.0006), and for disappointing results or persistent pain (p = 0.001). The first recourse was the conciliation and compensation commission (CCI) in 136 cases (55.1%), the civil court (TGI) in 88 cases (35.6%) and amicable settlement in 23 cases (9.3%). The mean time between surgery and the complaint was 32.8 ± 25.7 months, and was shorter in the case of an amicable procedure (p < 0.001). The lawsuit's mean duration was 15.6 ± 11.2 months, but longer in case of civil proceedings (p < 0.0001). The experts found no negligence in 81.8% of cases (n = 202). Infections were the leading cause of recourse to the conciliation and compensation commission (p < 0.0001), while technical errors were the main reason for complaints settled in an amicable procedure (p = 0.035). It was found more proven negligence in case of amicable procedures (p < 0.0001). The mean amount of compensation was 60,968.45€. No significant difference could be found regarding the median values of compensation between the reason of complaint. The amount of compensation was higher in civil court proceedings than in any others (p = 0.02).
    Conclusion: The main reasons for arthroscopy litigation in France are reported in this study, specifying how they are managed upstream of possible legal proceedings. The knee is the main joint involved. Patient information, close follow-up associated with early and appropriate management of complications are the main ways to reduce complaints.

    Abstract During the Covid-19 pandemic, location of the SARS-CoV-2 infected patients inside the hospital is a major issue to prevent viral cross-transmission. The objective of this study was to evaluate the risk of contamination through aerosol by using a global approach of the multiple environmental parameters to simulate, including seasonal context. A computational fluid dynamic (CFD) simulation based on the Lattice Boltzmann Method approach was used to predict airflow on the entire floor of a private hospital in Paris. The risk of contamination outside the rooms was evaluated by using a water vapor mass fraction tracker. Finally, the air contamination was estimated by a "cough model" producing several punctual emissions of contaminated air from potentially infected patients. In a winter configuration, the simulation showed a well-balanced ventilation on the floor and especially inside the rooms. After cough emissions from COVID-positive rooms, no significant contamination was observed in the circulation area, public waiting space and nurse office. On the contrary, in a summer configuration, the temperature difference due to the impact of the sun radiation between both sides of the building created additional air transport increasing the contamination risk in neighboring rooms and public spaces. Airborne spread was limited to rooms during winter conditions. On the contrary, during summer conditions, market airflow with potentially contaminated air coming from rooms located on the side of the building exposed to solar radiation was evidenced. These observations have implications to locate infected patients inside the building and for the conception of future health care structures.

    Abstract Background: The microbiological diagnosis of bone and joint infections (BJI) currently relies on cultures, and the relevance of molecular methods is still debated. The aim of this study was to determine whether polymerase chain reaction (PCR) could improve the etiological diagnosis of BJI.
    Methods: A prospective study was conducted during a 4-year period at Lariboisiere University Hospital (Paris, France), including patients with suspicion of infectious spondylodiscitis, septic arthritis, prosthetic joint infections, and respective noninfected groups. Clinical and radiological data were collected at inclusion and during follow-up. All samples were analyzed by conventional cultures and 16S ribosomal deoxyribonucleic acid (rDNA) gene (16S-PCR). Specific cultures and PCR targeting
    Results: After expert committee analysis, 105 cases of BJI cases and 111 control patients were analyzed. The most common pathogens of BJI were staphylococci (30%),
    Conclusions: Our study showed the benefit of 16S-PCR and PCR targeting
