The Dynesys ® system is a non-fusion pedicular dynamic stabilization system. The aim of our study is to evaluate the clinical outcomes in patients with degenerative disc disease and/or stenosis, and to measure the prevalence of screw loosening and breakage after 4 years of follow up.All patients who underwent surgery with Dynesys ® system in 2008 were reviewed. The surgery was performed...
The treatment of calcaneal fractures with joint involvement continues to be a challenge for the traumatologist. The inconsistent clinical results and frequent complications of open reduction have made it difficult to standardize surgical management of these injuries. The new percutaneous construction techniques appear to have a future due to a lower complication rate and better technical accessibility.
To describe the development and characterisation of a vitroceramic material as well as the initial response of adult mesenchymal stem cells (MSCs-A) isolated from bone marrow.The material was obtained by heating glass with composition in mol% 55SiO 2 -41CaO-4P 2 O 5 by a sol gel method. Cells were isolated from direct iliac crest aspirates from young adult patients. An analysis...
To assess the efficacy of the Vira ® system for the treatment of calcaneal fractures by means of a secondary subtalar arthrodesis.We prospectively assessed 23 secondary subtalar arthrodeses. Eighteen cases were “in situ” arthrodeses, 4 out of them were combined with a lateral decompression and 5 were corrections of malunions by means of calcaneus osteotomies. All cases were addressed with...
The aim of this study is to compare and analyse the changes in plantar pressure whilst walking, in patients with ankle arthrodesis by means of kinetic and kinematical motion analysis and plantar support studies.We studied 17 patients (14 males and 3 females) with posttraumatic ankle arthrodesis (13 right side and 4 left side) with a minimum follow up of three years (3–9 years). There were no other...
When it comes to performing a safe arthroscopic procedure, obtaining an optimal view of the surgical field is essential. For this, a proper functioning of the optical systems and an appropriate distension of the joint are required. With this goal in mind, irrigation systems have been developed that inject fluid into the joint during the arthroscopic procedure. The pressure exerted by the fluid distends...
To develop instruments that can restore the shape of a fractured calcaneus and facilitate minimally invasive primary arthrodesis of the subtalar joint in severe calcaneal intraarticular fractures.We studied a new osteosynthesis system for calcaneal fractures in three consecutive phases: a) system design, b) biomechanical tests and c) prototype testing in cadavers.The basic characteristics of the original...
