In patients suffering of osteoarthritis of the hip (a degenerative condition of the hip that finally leads to anatomical and functional impairment of the joint), the only efficient treatment in advanced stages of the disease is the surgical replacement of the joint with a total hip prosthesis. Unfortunately, despite improving the composition of the materials from which these prostheses are made...

BACKGROUND In joint prosthetic surgery, various methods are used to provide implant stability. We used an injectable bone substitute, composed of calcium sulfate/hydroxyapatite, as bone defect filler to stabilize a tibia prosthesis in an experimental rabbit model. The aim of the study was to investigate and compare the stability of prosthetic fixation with and without the use of an injectable b...

Artificial finger joints lack the long-term clinical success seen with hip and knee prostheses. In part, this can be explained by the challenges of rheumatoid arthritis, a progressive disease which attacks surrounding tissues as well as the joint itself. Therefore, the natural finger joints' biomechanics are adversely affected, and consequently, this imbalance due to subluxing forces further ch...

OBJECTIVE The study aims to compare the stress shielding effects of implantable anatomical and traditional prostheses after in vitro total hip joint replacement simulation. The study serves as a biomechanical basis for novel artificial prostheses and for clinical hip joint replacements. METHODS Sixteen femoral specimens from adult male corpses were randomly divided into two groups: the tradit...

INTRODUCTION Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilater...

Because conventional above-knee prostheses are passive type device with constant mechanical properties, knee joint motions are not similar to that of normal persons. On the other hand, active type prostheses can improve swing phase gait but these are expensive, heavy and consume large energy. So the semi-active type prostheses are presented. We propose to use the rotary MR damper. The torque di...

Objectives This study compared full-arch screw-retained implant-supported fixed dental prostheses (FSI-FDPs) and telescopic-retained with a professional retrieval system (FTI-FDPs) on marginal bone loss (MBL), the risk indicators peri-implantitis rate after 7–13 years. Material methods Sixty five edentulous patients were treated 86 592 implants. The FSI-FDP group comprised 26 (32 prostheses, 20...

BACKGROUND There is no universal hip implant suitably fills all femoral types, whether prostheses of porous short-stem suitable for Hip Arthroplasty is to be measured scientifically. METHODS Ten specimens of femurs scanned by CT were input onto Mimics to rebuild 3D models; their *stl format dataset were imported into Geomagic-Studio for simulative osteotomy; the generated *.igs dataset were i...
