The pelvis bone resection-reconstruction surgery is one of the most challenging fields in orthopedics. Being applied for tumors, as for other complex reconstruction cases, this type of surgery needs careful planning and is time consuming, in order to obtain proper accuracy. Unfortunately not all the time the expected accuracy is met, with consequences for the patients. PSI proved to provide good cutting accuracy during simulated tumor surgery within the pelvis. This article present a series of 4 patients operated in our department between June 2014 and Mars 2015 for tumors resectionreconstructions. The patients were imaged using a CT and an MRI scan and the images were reconstructed in 3D. According to the bone bank stock, the most similar allograft was chosen and the stored CT scan was reconstructed in 3D. Patient specific instruments (PSI) were designed and manufactured using rapid-prototyping technology for the resection of the native tissues as for the resection of the careful se...

Tendons and ligaments injuries have become more and more common due to the increase of the general populations interest in sports and physical activities. Beginning with the 1970s many researchers have tried to reconstruct the torn ligaments and tendons, at first using products such as Polyflex and Proplast ligaments, with poor results. In recent years the use LARS ligament has been researched. The Ligament Augmentation and Reconstruction System, now at its 3rd generation, is an artificial ligament made out of polyethylene terephthalate (PET) that over time allows tissue ingrowth, recreating the natural orientation of anatomical ligament and tendon fibers.
The lack of meniscal tissue increases the risk of early cartilage degeneration. Classic treatment includes suturing and partial menscectomies, total meniscectomies being abandoned. Modern treatments are based on the implantation of special scaffolds that replace some of the lost meniscal tissue. This paper reviews the basic principles of modern treatment of the menisci and it includes a retrospective study, in which a total of 10 patients (7 men and 3 women, mean age: 28.28 (21-38)) were enrolled. All patients had previous surgery and were subjected to arthroscopic treatment with a biodegradable scaffold (Actifit®). They received KOOS (Knee Injury and Ostheoarthritis Outcome Score), Lysholm and Tegner score. The Tegner score was not very useful in determining the success or failure of the surgery. The Lysholm and KOOS score results improved at the 1-year follow-up. The results of the scores that the patients filled out, showed an improvement in their preoperatively knee related problems. The Actifit® scaffold is safe and effective in treating meniscal defects.
ACL rupture frequently occurs due to a pivotal movement between the tibia and femur. In lack of reconstruction surgery of the ligament, osteoarthritis appears. The ACL graft can be fitted through different systems: compression, expansion and suspension. Although different in technique, the clinical end-results show little differences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
