UNLABELLED Unconstrained tripolar hip implants provide an additional bearing using a mobile polyethylene component between the prosthetic head and the outer metal shell. Such a design increases the effective head diameter and therefore is an attractive option in challenging situations of unstable total hip arthroplasties. We report our experience with 54 patients treated using this dual mobilit...

BACKGROUND The tibial pilon fractures represent a complex therapeutic problem for the orthopedic surgeon, given the frequent complications and outcomes disabling. The recent medical literature indicates that the best strategy to reduce amount of complications in tibial pilon fractures is two-stages procedure. We describe our experience in the primary stabilization of these fractures. METHODS ...

We calculated the electric fields induced in the brain during transcranial current stimulation (TCS) using a finite-element concentric spheres human head model. A range of disc electrode configurations were simulated: (1) distant-bipolar; (2) adjacent-bipolar; (3) tripolar; and three ring designs, (4) belt, (5) concentric ring, and (6) double concentric ring. We compared the focality of each co...

Drug addiction is a destructive misfortune that leads to recession in all social fields. For this reason, proper treatment of addiction should be seriously considered. Formerly, the effectiveness of TENS and ICWS methods on the reduction of withdrawal syndrome signs in the rat was evaluated separately. In this study the interaction of these two methods were analyzed. For this purpose, four grou...

A case of a large recurrent hydatid cyst involving the right ilium and right hip treated with excision of the cyst, Total hip replacement and revision of the acetabular component with a Tripolar articulation for cyst recurrence and acetabular component loosening is presented along with a review of the relevant literature. To our knowledge there is no reported case of Total Hip replacement and r...

transcutaneous electrical nerve stimulation (tens) is an analgesia inducing method with increasing applications in clinical procedures. in this study we tried to evaluate the role of the adrenergic system and its different adrenoceptor subtypes in tens-induced analgesia. two types of low and high frequency electrical stimuli were used in rats through needle electrodes, inserted at the base of t...
