Introduction: The treatment of osteoarticular infections in Africa is a medical and surgical challenge due to the difficulties in managing antibiotic therapy after the surgical procedure. The objectives of this study were to identify the types of bacteria in osteoarticular lesions in patients treated in Chad and to determine the spectrum of resistance encountered and the efficacy of available antibiotics., Material and Methods: This is a retrospective study of all intraoperative osteoarticular and soft tissue samples taken in a French Role 2 Medical Treatment Facility of N'Djamena during surgery for chronic osteoarticular infections, in Chad, for 1 year., Results: A total of 160 bacterial strains were identified, with a predominance of Gram-negative bacillus (GNB) and staphylococcus infections. Among staphylococci, 80% were methicillin-sensitive streptococci which were generally multidrug-sensitive. Enterococci were resistant to third-generation cephalosporins, first-generation fluoroquinolones and gentamycin. Among GNB, there was a predominance of enterobacteria compared with non-fermenting GNB, of which 52% were multidrug-resistant and produced extended spectrum beta-lactamases (ESBL)., Conclusion: Staphylococcus aureus infections are most often sensitive to available antibiotics and therefore have better prognoses than infections caused by other bacteria. In contrast, in half of the cases of GNB, infections were caused by bacteria producing ESBL, thus posing the problem of multidrug-resistance, the risks of which are increased in precarious situations. Therefore, the type of bacteria appears to be a major prognostic factor in the treatment of osteoarticular infections in a Role 2 in Chad. This criterion will need to be considered before any treatment decisions are made., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Exposure of the coracoid process during arthroscopic stabilization of acute acromioclavicular disjunctions (ACDs) can be achieved either by passing an extra- articular optical portal through the subacromial space or by an intra-articular optical route through the glenohumeral joint with opening of the rotator interval. The objective of our study was to compare the impact on the functional results of these two optical routes. This was a retrospective, multicentre study that included patients operated on for an acute acromioclavicular disjunction arthroscopically. The treatment consisted of surgical stabilization under arthroscopy. The surgical indication was retained for an acromioclavicular disjunction of grade 3, 4 or 5, according to the Rockwood classification. Group 1, which consisted of 10 patients, was operated on with an extra-articular subacromial optical route, and group 2, which consisted of 12 patients, was operated on with an intra-articular optical route with opening of the rotator interval according to the habits of the surgeon. A follow-up of 3 months was performed. The functional results were evaluated for each patient using the Constant score, Quick DASH, and SSV. The delays in returning to professional and sports activities were also noted. A precise postoperative radiological analysis made it possible to analyse the quality of the radiological reduction. No significant difference between the two groups was found between the Constant score (88 vs. 90; p = 0.56), Quick DASH (7 vs. 7; p = 0.58), or SSV (88 vs. 93; p = 0.36). The times to return to work (6.8 weeks vs. 7.0 weeks; p = 0.54) and sports activities (15.6 weeks vs. 19.5 weeks; p = 0.53) were also comparable. The quality of the radiological reduction was satisfactory in the two groups and did not depend on the approach. No clinically or radiologically significant differences between the extra-articular and intra-articular optical portals in the surgical treatment of acute ACDs were found. The optical route can be chosen according to the habits of the surgeon.

Purpose: This study reports on complications following extended tourniquet application in patients with combat extremity injuries treated by the French Military Health Service in the Sahelian strip., Methods: A retrospective review was performed in a French forward medical treatment facility deployed in Gao, Mali, between 2015 and 2020. All patients treated for an extremity injury with the application of at least one tourniquet for a minimum of 3 h were included. Prehospital data were injury pattern, associated shock, tourniquet location, and duration. Subsequent complications and surgical procedures performed were analyzed., Results: Eleven patients with a mean age of 27.4 years (range 21-35 years) were included. They represented 39% of all patients in whom a tourniquet was applied. They had gunshot wounds (n = 7) or multiple blast injuries (n = 4) and totaled 14 extremity injuries requiring tourniquet application. The median ISS was 13 (interquartile range: 13). Tourniquets were mostly applied proximally on the limb for a mean duration of 268 min (range 180-360 min). Rhabdomyolysis was present in all cases. The damage control surgeries included debridement, external fixation, vascular repair, and primary amputation. Ten injuries were complicated by compartment syndrome requiring leg or thigh fasciotomy in the field or after repatriation. Two severely injured patients died of their wounds, but the others had a favorable outcome even though secondary amputation was sometimes required., Conclusions: Extended and proximal tourniquet applications led to significant morbidity related to compartment syndrome and rhabdomyolysis. Hemorrhagic shock, mass casualty incident, and tactical constraints often precluded revising the temporary tourniquet applied under fire., (© 2021.

Introduction: In this age of social media, with an ever-higher profile for surgery and rankings for the general public, patients' criteria for choosing a surgeon or team are not precisely known, especially in France. We therefore conducted a prospective study concerning anterior cruciate ligament reconstruction: (1) to determine how patients came to know their surgeon; (2) to identify factors affecting final choice., Hypothesis: Patients' choice of surgeon is affected by scores found in social media and rankings found in the press., Material and Method: A prospective continuous study included all patients operated on, without standardization of technique, in 3 hospitals (public and private sector). An anonymous questionnaire on surgeon selection criteria, scored 0 to 10, was distributed on a voluntary basis on the day of surgery scheduling., Results: One hundred and five patients were included. They had come to know of their surgeon via family or friends or their personal physician in more than two-thirds of cases. The essential criterion of final choice was the clarity of the written and oral information provided in consultation (mean score, 8.09±1.83). Other factors included wait-time to surgery (7.39±2.25) and to first consultation (7.26±2.01) and the surgeon's reputation (7.42/10±2.43)., Conclusion: "Word of mouth" and the quality if information provided in consultation motivated final choice, more than any influence of social media or press hospital rankings., Level of Evidence: IV; prospective observational study without control group., (Copyright © 2021 Elsevier Masson SAS.

Introduction: Intramedullary (IM) nailing is the gold standard for treating long bone fractures in developed countries because of its minimally-invasive application and good biomechanical properties. In precarious conditions, external fixation or open plate fixation are often performed because surgeons do not have the means to carry out IM nailing. However, these procedures can lead to infection-related complications and mechanical failures. The aim of our study was to describe the outcomes and postoperative complications of IM nailing of closed, long bone fractures in patients operated in a French front-line combat surgical unit (role 2+). Our hypothesis was that IM nailing is a reliable technique with low morbidity for the initial treatment of long bone fractures, even in precarious situations., Material and Methods: This was a prospective, single-center, descriptive study of patients operated on between April 2016 and November 2017. All the patients with a closed femur or tibia fracture who were treated by IM nailing were eligible, no matter their time to surgery. The minimum follow-up was 6 months. The primary endpoint was the absence of infection-related complications and the secondary endpoint was fracture union., Results: Fifty-eight patients were reviewed after an average follow-up of 4.7 months (range, 3-15 months). The mean patient age was 35.2 years (15-85 years) and the majority of patients were men (52 of 58). The fracture was in the femur in 74.1% (n=43) of cases and in the tibia in 25.9% (n=15) of cases. The time to surgery averaged 122.3 days (7-720 days) with a median of 60 days. In 74% of cases (n=43), fracture realignment required an open surgical approach. The postoperative course was considered normal in 96.6% of cases (n=51). No infections were reported as of the last follow-up visit. Union occurred in an average of 4 months in 70.7% of cases (n=41). There were three cases of nonunion after 6 months., Discussion: Even in precarious situations, IM nailing is an effective, reliable method with a low complication risk and high union rate for the treatment of neglected long bone fractures. This surgical treatment is well suited to the poor sanitary conditions on the African continent., Level of Evidence: II, low-powered prospective study., (Copyright © 2018 Elsevier Masson SAS.

The prevalence of obesity is increasing. In orthopaedic surgery, the impact of obesity is felt. The aim is to take stock of the consequences of obesity for patients at each stage of management. In this mini-review, we identify the main pathophysiological factors, specific orthopaedic complications and consequences to consider at each stage of management. Obese patients are subjected to a chronic inflammatory state and biomechanical stress. This augments the risk of sepsis and trauma, musculoskeletal damage, the frequency of organ failure and thus, morbidity and mortality. This results in more complex and longer supportive care. At each stage of care, surgeons and doctors have to adapt to optimize care. It is necessary to obtain timely and accurate information from the patient. Patient information is necessary. Being obese in orthopaedics is a factor in poor prognosis. Treatments need to be adapted. This requires specific preparation at each step.

Introduction: The development of damage control orthopedics (DCO) procedures has led to the development of temporary unicortical external fixators (TUEFs) intended to limit deep infectious complications and facilitate early conversion to internal fixation., Methods: A retrospective study was conducted in two French military trauma centers, including on patients being treated for tibial fractures with a TUEF (UNYCO ® - Orthofix ® ) followed by an early conversion to intramedullary nailing., Results: Eleven patients with an average age of 41 were included between September 2015 and June 2017. A total of 12 TUEFs were implanted for one closed fracture and 11 open fractures, including one type I, eight types II, and two Gustilo types IIIB. The indication of DCO was related to hemodynamic instability in three cases, to the severity of soft tissue lesions in eight cases, and to the context of treatment in one case. The conversion to IM nailing was made after an average of 7.6 days. No significant loss of reduction was observed until internal osteosynthesis, which was performed with "fixator in place" in ten cases. The coverage of Gustilo type III injuries was performed by free flap transfers at the same time as IM nailing. All the patients were reviewed with an average follow-up of 16.5 months. Bone union was achieved in all cases. Two IM nailing dynamizations were carried out, but no bone grafting was required. Two cases of pandiaphysitis were observed and treated without functional complications., Discussion: Despite a limited number of patients, this study demonstrates the reliability of the TUEF to maintain the reduction of tibial fractures and facilitate early conversion to IM nailing. Unicortical fixation does not prevent septic complications related to the severity of soft tissue injuries., (© The Authors, published by EDP Sciences, 2018.)

Introduction: Total elbow arthroplasty (TEA) is one option in distal humerus fracture in elderly osteoporotic patients., Hypothesis: The study hypothesis was that, in patients aged 70years or more, TEA provides functional results and ranges of motion compatible with everyday activity, with a complications rate equal to or lower than with internal fixation, and no loss of autonomy or cognitive impairment., Material and Methods: In this retrospective study, 21 patients receiving TEA for distal humerus fracture were included. Mean follow-up was 3.2years, with functional (Quick DASH and MEPS), cognitive (MMSE), autonomy-related (ADL) and radiological assessment (Morrey)., Results: Mean MEPS was 84 and QuickDASH 32.4. Mean extension deficit was 22°, and mean flexion 125°. There was no loss of autonomy or cognitive impairment. The complications rate was 9.5%. There were no revision surgeries., Discussion: TEA proved reliable in comminuted distal humerus fracture in elderly patients. Functional results were comparable to those in the literature, and the complications rate was lower. Long-term implant survival needs confirmation to validate this option as a treatment of choice in these indications in geriatric traumatology., Type of Study: Retrospective non-comparative, single-center., Level of Evidence: 4., (Copyright © 2017 Elsevier Masson SAS.

Introduction: Knee arthroplasty causes significant blood loss. Different blood-saving measures exist like retransfusion of unwashed salvaged blood. Some studies question the quality of this blood and in particular its ability to clot. These studies use "static" coagulation tests reflecting only partially the reality, unlike viscoelastic methods. The main objective of this study was to evaluate the salvaged blood thromboelastometric profile using ROTEM® system and to compare these results with patient venous blood., Materials and Methods: We performed an observational, prospective, single-center study conducted over 3 months in 2013. Agreement of local ethical committee and patient consent were obtained beforehand. All adult patients who underwent a primary total knee arthroplasty were included. A thromboelastometric profile and standard laboratory tests (hemoglobin, platelets count, PT, aPTT, fibrinogen) were performed in the same time on patient venous blood and on unwashed salvaged blood in the PACU., Results: Twenty patients were included. The median duration of surgery was 93 minutes. Thirteen patients (65%) received tranexamic acid during procedure. The median volume of shed blood was 225 mL. Two patients (10%) received a reinfusion. Analysis of shed blood showed a major deficiency of clotting factor in standard biology (PT<10%) and an absence of clot formation in thromboelastometric test (In-tem®, Ex-tem®, Fib-tem® or Ap-tem®). Compared to venous blood, shed blood had significantly lower hemoglobin levels: 8.8 vs 13.5 g/dL (P<0.0001). Allogenic transfusion concerned 5% of patients., Discussion: In this work, we confirmed that shed blood was naturally uncoagulable probably due to a multifactorial mechanism involving a major clot factor deficiency and an activation of fibrinolysis., (Copyright © 2015 Elsevier Masson SAS.
