Which type of supra-syndesmal fractures Weber C or Equivalent Weber C have the best reduction of the distal tibio-fibular syndesmosis? A prospective CT-scan investigation on 60 ankles.

Introduction: The reduction of the distal tibiofibular syndesmosis (SyTFd) is a crucial factor in the functional prognosis following a suprasyndesmotic ankle fracture. Few studies have compared, using computed tomography (CT), the quality of SyTFd reduction in Weber C ankle fractures (WebC) and Equivalent Weber C (EqWebC) fractures, where there is a medial ligament injury instead of a bony malleolar lesion. This CT-based study aimed to answer the following questions: (1) Do Weber C fractures allow for better reduction of the distal tibiofibular syndesmosis compared to Equivalent Weber C fractures? (2) Are the functional outcomes one year postoperatively better for Weber C fractures compared to Equivalent Weber C fractures?

Hypothesis: The hypothesis was that WebC fractures would present better reduction of the SyTFd than EqWebC fractures due to the restoration of bone anatomy, considering the bony nature of the medial ligament involvement.

Does double distal locking reduce non-union rates in intramedullary nailing for humeral shaft fracture?

Introduction: Intramedullary nailing is one of the surgical treatments for humeral shaft fracture. Non-union is a common complication, with rates of 10-20%. The objective of this study was to compare non-union in humeral shaft fractures treated by intramedullary nailing with double distal locking, single distal locking or no locking.

Dedicated locking plate reduces non-union risk in open ankle fusion in obese patients.

Introduction: Obesity is a growing public health concern. In ankle osteoarthritis, non-conservative treatment in advanced stages consists in ankle fusion, or else total ankle replacement, for which obesity is a relative contraindication. One of main complications of ankle fusion is non-union.

The "Metaizeau trick" to facilitate medullary pubic ramus screw insertion: A technical note.

Minimally invasive procedures have recently seen an increase in the treatment of pelvic ring disruptions and select acetabular fractures. Similar to ilio-sacral screws, the superior pubic ramus screw is becoming a preferred method for treating unstable pelvic ring fractures. While the osteology of the superior pubic ramus is well understood and has inherent variability, standard screw insertion techniques work effectively in most cases.

Validation of the postoperative Quality of Recovery-15 questionnaire after emergency surgery and association with quality of life at three months.

Purpose: The Quality of Recovery-15 (QoR-15) tool, validated for measuring postoperative recovery following scheduled surgeries, has not been psychometrically assessed in emergency contexts. Moreover, the QoR-15's associations with long-term outcomes remain underexplored. This study aimed to confirm the validity and reliability of the QoR-15 following emergency surgery and assess its association with three-month postoperative quality of life.

In vitro comparative study of deformation of 3D-printed models using different polylactic acids treated by steam sterilization.

Introduction: 3D printing, which is becoming ever more widespread in orthopedic surgery, requires specific materials. Polylactic acid (PLA) is the most widely used in general-purpose 3D printing, but its thermosensitivity can be incompatible with sterilization. Even so, it is easy to use, inexpensive, non-toxic and biodegradable.

Corona mortis and pelvic dissection: Understanding the relationship between anatomical structures and bone areas.

Pelvic fractures are becoming increasingly frequent. The gold standard for surgical managements remains open procedures. Despite its excellent biomechanically results, it can lead to many complications.

Total Ankle Replacement in Cavovarus Deformity: How Far Can We Go?

Because of the good functional results and satisfactory implant survival achieved with modern models, total ankle replacement (TAR) has become a legitimate alternative to ankle fusion. However, alignment and balance are mandatory for implant survival. Satisfactory results can be achieved in patients with significant preoperative deformity if alignment and balance were obtained.

Ferric derisomaltose and tranexamic acid, combined or alone, for reducing blood transfusion in patients with hip fracture (the HiFIT trial): a multicentre, 2 × 2 factorial, randomised, double-blind, controlled trial.

Background: Anaemia and blood transfusion are associated with poor outcomes after hip fracture. We evaluated the efficacy of intravenous iron and tranexamic acid in reducing blood transfusions after hip fracture surgery.

Methods: In this double-blind, randomised, 2 × 2 factorial trial, we recruited adults hospitalised for hip fractures in 12 medical centres in France who had preoperative haemoglobin concentrations between 9·5 and 13·0 g/dL.

Management of acute grade IV and greater acromioclavicular dislocations: Open acromioclavicular brace versus arthroscopic double DogBone® endobutton.

Introduction: Several surgical techniques exist to manage grade IV acute acromioclavicular dislocation (ACD). However, the conventional acromioclavicular brace technique (ACB) has never been compared to the arthroscopic DogBone® (DB) double endobutton technique. The aim of this work was to compare the functional and radiological results of DB stabilization with those of ACB.

C-Nail® locking nail versus conventional plate for thalamic calcaneal fractures.

Background: Surgery for displaced intra-articular calcaneal fractures (DIACFs) is often followed by skin complications that adversely impacts the functional outcomes. Minimally invasive techniques have been developed to decrease the risk of skin complications. The objective of this study was to compare C-Nail® locking-nail fixation to conventional plate fixation for DIACFs.

Clinical and radiological outcomes of internal fixation of complex talar neck and body fractures with locking plates through a dual approach.

Introduction: Talar fractures are rare and surgical treatment has not been standardized. The literature is rather poor on preserving talar vascularization in single or dual approaches. A dual approach allows better exposure and should limit devascularization.

Pediatric fracture reduction in the emergency department.

Limb fractures are a large part of pediatric trauma activity. Conservative treatment is possible because of children's bone remodeling potential. In case of displaced fractures, when a closed reduction can be done in the emergency room (ER), this avoids general anesthesia, hospitalization and the associated costs.

Does isolated arthroscopic anterior acromioplasty modify critical shoulder angle?

Introduction: Critical shoulder angle (CSA)>35° correlates significantly with primary rotator cuff tear and re-tear after repair. Acromial axial orientation varies between individuals. The present study aimed to assess the impact of strictly anterior acromioplasty on CSA.

Microarchitecture of titanium cylinders obtained by additive manufacturing does not influence osseointegration in the sheep.

Large bone defects are a challenge for orthopedic surgery. Natural (bone grafts) and synthetic biomaterials have been proposed but several problems arise such as biomechanical resistance or viral/bacterial safety. The use of metallic foams could be a solution to improve mechanical resistance and promote osseointegration of large porous metal devices.

WITHDRAWN: Does anterior arthroscopic acromioplasty modify critical shoulder angle?

This article has been withdrawn because we accidentally published the same article twice due to an error by the Managing editor/Elsevier. The correct version of the article has been published later in Orthop Traumatol Surg Res, 108 (2022) 103040, https://doi.org/10.

Does the retention of osseointegrated prosthetic implants during the surgical management of chronic infections following reverse total shoulder arthroplasty (RTSA) influence functional outcomes without impacting the efficacy of the infection treatment?

Introduction: The gold standard (GS) for treating chronic infections following reverse total shoulder arthroplasty (RTSA) is a complete exchange of the prosthesis carried out in one or two stages. This surgical procedure, which may damage the bone stock, can result in poor functional outcomes due to intraoperative complications. The purpose of this study was to compare the GS to a surgical technique that retained osseointegrated implants: the partial one-stage exchange.

Comparison of double screw fixation versus tension-band fixation after olecranon osteotomy for complex distal humerus fractures.

Introduction: Supra- and intercondylar elbow fractures are surgically challenging given the intra-articular comminution. Various surgical approaches have been described. Among these-olecranon osteotomy-provides optimal joint exposure but is associated with several complications.

Histochemical identification of wear debris released by alumina-on-alumina hip prostheses in the periprosthetic tissues.

Background: Tribological studies have shown that the most used couples for hip prostheses consist of metal-on-polyethylene and alumina-on-alumina prostheses. Over time, wear products accumulate in the joint cavity and in the periprosthetic tissues. Although polyethylene and metal are easily identifiable by microscopy in periprosthetic tissues, alumina particles are very difficult to identify.

Fast-track care for pertrochanteric hip fracture: What impact on function and autonomy after discharge?

Introduction: Fast-track treatment of pertrochanteric fracture is being developed in traumatology. The present study hypothesis was that fast-track treatment of pertrochanteric fracture does not jeopardize patient autonomy.

Material And Method: A single-center prospective comparative observational study, conducted from 2014 to 2016 in the University Hospital of Angers, France, included patients presenting with isolated A1 or A2 pertrochanteric fracture on the AO classification, managed by intramedullary nailing and requiring transfer to Post-acute Recovery (PAR).
