Intérêt de la navigation non invasive dans l'arthroplastie totale de genou

During surgery of total knee arthroplasty, we use a computerized non invasive navigation (Brainlab Victor Vision CT-free) to assess the accuracy of the bone cuts (navigation expresse). The purpose of this study is to evaluate non invasive navigation when a total knee arthroplasty is achieved by conventional instrumentation. The study is based on forty total knee arthroplasties. The accuracy of the tibial and distal femoral bone cuts, checked by non invasive navigation, is evaluated prospectively. In our clinical series, we have obtained, with the conventional instrumentation, a correction of the mechanical axis only in 90 % of cases (N = 36). With non invasive navigation, we improved the positioning of implants and obtained in all cases the desired axiometry in the frontal plane. Although operative time is increased by about 15 minutes, the non invasive navigation does not induce intraoperative or immediate postoperative complications. Despite the cost of this technology, we believe that the reliability of the procedure is enhanced by a simple and reproducible technique.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Luxation acromio-claviculaire complexe chez un patient de 74 ans

Acromioclavicular dislocation is a frequent pathology commonly encountered in traumato-logy. Therefore, its management is generally standardized, guided by clinical and radiological evaluation. This can range from conservative treatment by limb immobilization and functional rehabilitation, to surgical treatment by using minimally invasive techniques. We present the particular case of a 74-year-old patient with an acromioclavicular dislocation associated with a non-displaced fracture of the coracoid process as well as of the spine of the scapula. This article aims to describe the diagnostic traps as well as discuss the treatment options for this complex presentation.SCOPUS: ed.jinfo:eu-repo/semantics/publishe
