This meta-analysis was performed to evaluate the efficiency and the safety of absorbable implants. Five major electronic databases (PubMed, Embase, Cochrane Library, SinoMed and Wanfang Data) were systematically searched for randomized controlled trials (RCTs) from their establishment to November 2012. Studies on absorbable implants and metal implants for ankle fractures were selected. The meta...

BACKGROUND The purpose of the study is an analysis of intrascleral drainage vessels formed in rabbits' eyes after non-penetrating deep sclerectomy (NPDS) with absorbable and non-absorbable implants, and comparison to eyes in which surgery was performed without implanted material. MATERIAL/METHODS NPDS was carried out in 12 rabbits, with implantation of non-absorbable methacrylic hydrogel (N=1...

OBJECTIVE To compare the functional results of ankle fractures treated with metallic and absorbable plates. Twenty patients were randomized into two groups (metallic and absorbable implant groups) and followed prospectively. In the immediate postoperative period, patients were immobilized with plaster casts for one week, which was replaced by a removable cast for another four weeks. Partial wei...

statement of the problem in recent decades, immediate implant placement has been proposed to eliminate undesirable consequences of conventional methods of delayed placement. in addition, because of the nature of this treatment method, a higher risk of complications such as infection and also higher failures rates may be expected purpose the aim of this study was to compare clinical outcomes of ...

PURPOSE To describe a staining technique that will enhance the visualization of non-absorbable T-Flux implants. METHODS The technique was applied to non-absorbable T-Flux implants. The implants were submerged for 5 to 10 minutes in a sodium fluorescein solution, and dried with a sponge when removed from the solution. DISCUSSION This is a very simple and easy procedure that uses a common flu...

PURPOSE We have developed a new method of segmenting the areas of absorbable implants and bone using region-based segmentation of micro-computed tomography (micro-CT) images, which allowed us to quantify volumetric bone-implant contact (VBIC) and volumetric absorption (VA). MATERIALS AND METHODS The simple threshold technique generally used in micro-CT analysis cannot be used to segment the a...

BACKGROUND Ankle fractures excluding pilon fractures, account for approximately 9% of all fractures with the majority being OTA type B injuries. Although surgeons generally treat undisplaced or minimally displaced injuries nonoperatively and displaced fractures operatively, opinions diverge regarding the management of those displaced fractures with acceptable closed reduction. There is also deb...

Magnesium materials are of increasing interest in the development of biodegradable implants as they exhibit properties that make them promising candidates. However, the formation of gas cavities after implantation of magnesium alloys has been widely reported in the literature. The composition of the gas and the concentration of its components in these cavities are not known as only a few studie...

Biodegradable implants made from polyglycolic and polylactic acid co-polymers undergo degradation by hydrolysis which results in loss oftheir mechanical strength. The degradation of 1.5 mm polyglycolide rods (Biofix) was studied after intramedullary and subcutaneous implantation in rabbits. Two weeks after implantation there was a 73% reduction in strength of the intramedullary implants and a 6...
