BACKGROUND Wire closure still remains the preferred technique despite reasonable disadvantages. Associated complications, such as infection and sternal instability, cause time- and cost-consuming therapies. We present a new tool for sternal closure with its first clinical experience and results. METHODS The sternal ZipFix(TM) System is based on the cable-tie principle. It primarily consists o...

This paper presents an experimental investigation into the compression behavior of shape memory alloy hybrid composites (SMAHC) subjected to quasi-static loading taking into account of rotation effects of shape memory wire in basalt continuous filament (BCF) direct roving epoxy composite. Two types of specimen prepared, the BCF direct roving reinforced epoxy composite filled with shape memory w...

STATEMENT OF THE PROBLEM Fixed retainers were developed to maintain incisor alignments after orthodontic treatments. Although the effects of fixed retainers on periodontal health are clinically studied, no studies have still evaluated the histological changes in the periodontium after the placement of thefixed retainers. PURPOSE The aim of this study was to evaluate the effects of customised ...

INTRODUCTION Reconstruction after wide resection for a sarcoma involving the knee extensor mechanism is challenging even if the tumor is small. CASE DESCRIPTION We report on four consecutive peri-patellar tendon sarcomas treated similarly at a single institution. Histological diagnoses were synovial sarcoma (two cases), clear cell sarcoma and extraskeletal Ewing's sarcoma (one case each). Fol...

Segmental long bone defects resulting from injury or surgical intervention are difficult problems to manage. Amputation, external fixators, vascularized fibular grafts, acute limb shortening, and various quantities of allograft and autograft have historically been the mainstays of treatment. Recently, the use of osteoinductive substances such as recombinant bone morphogenic proteins, and osteoc...

Titanium surfaces processed by wire-type electric discharge machining (EDM) are microfabricated surfaces with an irregular morphology, and they exhibited excellent in vitro bone biocompatibility. In this study, the efficiency of in vivo osteogenesis on EDM surfaces was investigated by surgically placing screw-shaped EDM-processed and machined-surface implants into the femurs of four Japanese wh...

OBJECTIVE The aim of this study was to establish an indirect, easy-to-use, predictable and safe means of obtaining the true degree of displacement of fractures of the neck of the fifth metacarpal bone, through oblique radiographic views. METHODS An anatomical specimen from the fifth human metacarpal was dissected and subjected to ostectomy in the neck region. A 1-mm Kirschner wire was fixed t...

In this study, Nickel-Chrome-Molybdenum alloy is manufactured using investment casting method with centrifugal device from a polyurethane foam model in regular and open-pore form, as hard tissue implant. The samples produced have 10, 20, 30 (±3) pores per inch 0.0008, 0.0017, 0.0027 g/mm3 densities, respectively. Young’s modulus, hardness mechanical behaviors of the were investigated by SEM, ED...

Description The OSTEOMED Logic Mandibular Distraction System is an intraoral bone distractor. It features various curved and straight bars activated with an activation wire (threaded wire) that has screw holes that are fixed to bone via 1.6mm or 2.0mm bone screws. The distractor is available in right and left versions. The activation wire is activated by a hex driver and is capable of distracti...

BACKGROUND It has been studied that the distribution of bone morphogenetic protein 2 is regular under bone defect situation. OBJECTIVE To observe the expression of bone morphogenetic protein 2 in rabbit radial defect site with different lengths. METHODS Forty-eight New Zealand rabbits were divided into two groups randomly. 0.5 cm bone defect and 3.0 cm bone defect were made by wire saw at t...
