Abstract. A mathematical model for studying the passive kinematics of condylartype total knee prostheses can be useful in planning and performing total joint replacement. If the insertion location and neutral length of knee ligaments is known, the passive kinematics of the knee can be calculated by minimizing the strain energy stored in the ligaments in any angular configuration of the knee. Th...

OBJECTIVE The purpose of the study was to evaluate results of dual mobility total replacement in a high risk population who take hip into hyperflexed position while sitting and praying on the floor. METHOD The study included 65 (35 primary total replacement and 30 complex total hip replacement) cases of total hip replacement using avantage privilege dual mobility cup system from biomet. A cem...

BACKGROUND To date, no experimental or clinical study provides detailed analysis of vascular impedance changes after total aortic arch replacement. This study investigated ventriculoarterial coupling and vascular impedance after replacement of the aortic arch with conventional prostheses vs. decellularized allografts. METHODS After preparing decellularized aortic arch allografts, their mechan...

Background. The goal of our study was to assess the efficacy of total hip replacement in the treatment of dysplastic arthrosis of the hip. Material and methods. Between November 2001 and June 2003 we performed total hip replacement in 40 patients (46 hips). Arthritic deformations were classified according to Crowe's classification scheme and operated using a variety of techniques and prostheses...

STUDY DESIGN Biomechanical analysis of a novel prosthesis based on the physiological curvature of endplate was performed. OBJECTIVE To compare the biomechanical differences between a novel prosthesis based on the physiological curvature of the endplate and the Prestige LP prosthesis after cervical disc replacement (CDR). SUMMARY OF BACKGROUND DATA Artificial disc prostheses have been widely...

Kinematic analysis for in vivo assessment of elbow endoprostheses requires knowledge of the exact positions of motion axes relative to bony landmarks or the prosthesis. A prosthesis-based reference system is required for comparison between individuals and studies. The primary aim of this study was to further develop an earlier described algorithm for fusion of radiostereometric analysis (RSA) d...

BACKGROUND Hip replacement surgery is a popular procedure that provides predictable, long-lasting and good effects. The use of short stem prostheses helps preserve an intact medullary cavity and proximal diaphysis. It has been demonstrated that the use of short stem prostheses leads to better clinical results compared to standard stem prostheses. The study aimed to assess the migration of the s...

Aims: The objective of this retrospective study was to evaluate the prevalence Helicobacter pylori (H. pylori) positivity, gastric atrophy, and intestinal metaplasia in patients with dyspeptic complaints who had undergone total hip knee replacement surgeries, compared a control group without prosthesis.
 Methods: consisted 51 prosthesis, while comprised 75 similar but prosthesis. Endoscopi...

In this study, we propose an ultra-facile approach to prepare a platinum silicide nanoparticle-modified tip apex (PSM tip) used for scanning Kelvin probe microscopy (SKPM). We combined a localized fluoride-assisted galvanic replacement reaction (LFAGRR) and atmospheric microwave annealing (AMA) to deposit a single platinum silicide nanoparticle with a diameter of 32 nm on the apex of a bare sil...
