Valgus deformity is less common than varus deformity in the arthritic knee, with an incidence of 10–15% in the population undergoing primary total knee arthroplasty (TKA) [1]. In cases of valgus knee, the surgeon uses the same set of instruments; however, the choice of approach, strategy for soft tissue balancing, order of ligament release, positio...

PurposeSevere varus and valgus knee deformities traditionally are replaced with constrained implants, with a number of disadvantages. We present our results in this challenging group using a low constraint deep-dish mobile bearing implant design. Methods One hundred fifty-four patients (170 arthroplasties) who underwent primary TKA using a deep-dis...

Introduction Le verrouillage des clous permet le contrôle de la longueur et de la rotation mais expose aux rayonnements. Récemment un viseur externe adapté au Clou Gamma Long® (Stryker®) a été développé. L’objectif de cette étude de pratique observationnelle était d’évaluer sa fiabilité. Notre hypothèse était que l’utilisation du viseur est systéma...

Intramedullary nail distal locking screws make it possible to control length and rotation but include an increased risk of radiation exposure. A distal targeting device was recently developed for long Gamma(®) nails (Stryker(®)). The aim of this practical observational study was to evaluate the reliability of this system. Our hypothesis was that th...

Les fractures fémorales inter-prothétiques sont rares, et leur traitement est discuté notamment sur la longueur de l’ostéosynthèse. L’apport des plaques verrouillées par voie mini-invasive est peu connu et peut contribuer à améliorer le taux de succès de l’ostéosynthèse.

Introduction: Interprosthetic femoral fractures are rare and raise unresolved treatment issues such as the length of the fixation material that best prevents secondary fractures. Awareness of the advantages of locked-plate fixation via a minimally invasive approach remains limited, despite the potential of this method for improving success rates....

A majority of osteoarticular and implant-related infections are due to staphylococci and biofilm formation. Combined therapy including rifampicin is frequently recommended. Indeed, rifampicin penetrates biofilms and kills adherent staphylococci, but cannot be administered as monotherapy because of the rapid emergence of resistant mutants. While sev...
