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...

objectives: microtia is the most commonly seen congenital ear defect, and involves an auricular deformity either unilaterally or bilaterally. the aim of this study was to fabricate silicone prostheses for a child with bilateral microtia using an innovative technique. methods: this method involved the construction of bilateral ear prostheses using clips, which were located within the layers of t...

background: pregnant patients with mechanical heart valves require anticoagulation. the risk of bleeding and embryopathy associated with oral anticoagulants must be weighed against the risk of valve thrombosis. methods: in this prospective study, undertaken between 1999 and 2009, 53 pregnancies (47 women with mechanical mitral valves; 29.8 ± 4.8 years old) were studied. patients were divided in...

introduction: even though modern technology progresses so rapidly, annals of otology are replete with so many challenging article, which often compare various types of prosthesis. since there has not been a prospective randomized clinical trial study which compares the hearing result of total ossicular replacement prosthesis made of titanium with omega connector and polycel in the literature, w...

background the ability to follow the distribution and migration of biologically active cells in human is essential for the development of cell-based therapies and diagnostics. nuclear medicine imaging is widely applied in clinic as an attractive technique for in vivo wbc and stem cell tracking. the aim of this study was to evaluate prosthesis infection of a 51 years old man with previous histor...

The loss of an upper limb significantly limits the functional activities of daily living. A huge emphasis is placed on the manipulation, shape, weight, and comfort of a prosthesis, to enable its use as an inherent body part. Even with technological advances, customized upper-extremity myoelectric prosthesis remain heavy and expensive. The high cost of upper-extremity prosthesis is an especially...

The aim of this study is to determine what factors constitute a quality prosthesis and ascertain which factors affect prosthesis satisfaction. Sixty-four women who received full funding for their prosthesis and 38 women who received their hospital's usual funding were recruited. Women rated the information provided about breast prostheses very highly, with 85% reporting that it was "very good" ...

This paper describes the design and evaluation of an experimental prosthesis-control system based on the concept of extended physiological proprioception (EPP). It was originally hypothesized that EPP control effected by residual shoulder motion could be effectively applied in multifunctional prostheses for shoulder disarticulation amputees. The experimental system developed for this study util...

BACKGROUND A study was designed to quantify the extent of porous osseointegration at the prosthesis-bone interface in the Prestige LP prosthesis containing a plasma-sprayed titanium coating. METHODS Using an anterior surgical approach, cervical disc arthroplasty was performed in 8 mature male goats at the C3-C4 segment, followed by implantation of the Prestige LP prosthesis. The vertebral spe...

Based on the thermo elasticity, using finite element method to analyze the stress of femur-prosthesis system when the hip joint has been replaced, a reference for the selection of prosthesis material is presented after discussing the thermo physical property of material which has an effect on the stress of femur-prosthesis system. We assume that prosthesis, bone cement and femur are linear elas...
