LCS mobile-bearing total knee replacement. A 10-year's follow-up study.
For the last three decades total knee arthroplasty surgery has been facing the renewed choice of using a traditional fixed-bearing design or a mobile-bearing system. A growing number of surgeons have elected to increase their use of mobile-bearing prostheses. We wanted to assess the reliability, in our hospital of this alternative choice. ⋯ Level IV. Therapeutic study.

ReviewFemoral offset: anatomical concept, definition, assessment, implications for preoperative templating and hip arthroplasty.
BACKGROUND OBJECTIVE: Femoral offset is supposed to influence the results of hip replacement but little is known about the accurate method of measure and the true effect of offset modifications. ⋯ Therefore, femoral offset restoration is essential to improve function and longevity of hip arthroplasty. CT-scan is more accurate than plain radiography to assess femoral offset. Hip resurfacing decreases offset without effect on function. Modular neck and computer assistance may improve intraoperative calculation and reproduction of femoral offset. Increasing offset with a standard cemented design may decrease long-term fixation. Level IV: Retrospective or historical series.

Pectus excavatum (PE) is a congenital deformity essentially responsible for an unattractive aspect, much more rarely for compression problems. The classical treatments consist either in filling the excavation or in open thoracic reconstruction (the Ravitch technique). Alternatively, the treatment described by Nuss raises the sternum with a retrosternal metallic bar placed under thoracoscopic guidance. We present the preliminary results of a series of 25 children operated on using this technique. ⋯ Level IV. Therapeutic Study.
