INTRODUCTION Distal radius fracture (DRF) is a common injury and various treatment modalities including open reduction and internal fixation (ORIF) with volar locking plate are available. More recently, a non-invasive external fixator has been used. AIMS To prospectively compare the use of a non-invasive external fixator with early dynamisation for DRF against ORIF with volar locking plate co...

PURPOSE To compare the stability of a novel, nonspanning external fixator with a standard volar locked plate for treatment of unstable distal radius fractures. METHODS A simulated, unstable, extra- articular distal radius fracture was created in six matched pairs of fresh frozen human distal radii. One of each pair was treated with a nonspanning external fixator [Mirza Cross Pin Fixator (CPX)...

Osteosynthesis surgery for rib fractures is controversial and challenging. This study developed a noval poly(ε-caprolactone) (PCL)-based biodegradable "cable-tie" fixator for osteosynthesis surgery for rib fractures. A biodegradable fixator specifically for fractured ribs was designed and fabricated by a micro-injection molding machine in our laboratory. The fixator has three belts that could b...

BACKGROUND AND PURPOSE External fixators allowing movement during fracture healing are commonly used for treatment of unstable distal radius fractures. The dynamic Dynawrist fixator with the distal pins in metacarpal bone may avoid fixation problems in comminuted fractures and may reduce the risk of nerve injury. We compared anatomical and functional outcome for the well-established Hoffmann co...

background paracentesis is a common bedside therapeutic and diagnostic procedure that requires insertion of a catheter into the peritoneal cavity; however, lack of a specialized fixator for securing the catheter causes frequent catheter kinking and patient discomfort. objectives this study aimed to demonstrate the efficacy of a designed paracentesis fixator in reducing patient discomfort and pr...

background: in children, inappropriate treatment of open femoral fractures may induce several complications. a few studies have compared the external fixator with flexible intramedullary nails in high-grade open femoral fractures of children. the present study aims at comparing results of these two treatment methods in open femoral fractures. methods: in this descriptive analytical study, 27 pa...

Nullor elements have applications not only in analog behaviour modeling but also in analog circuit design and analysis. Fixator-norator pair, the emerging tool in analog design is a combination of a nullor and sources. A method for the realization of fixator-norator pair is discussed in this paper. Application of fixator-norator pair into a circuit makes it possible to perform the AC and DC des...

The purpose of this study was to evaluate the influence of intramedullary (IM) alignment used in combination with an Ilizarov external fixation on the healing index (HI) and lengthening index (LI) in the treatment of congenital leg length discrepancies (LLD). This study included 35patients aged from 3.5 to 19 (average age 10.73) who underwent thl egalisation procedure using an Ilizarov external...

The results of treatment using a locally-designed external fixator in 20 patients are presented. Open fractures were the main indications for external fixation. Pin tract infection occurred in 8 patients. Only 2 patients had unstable fixation which required removal of the device. One third of patients developed malunion exceeding 15 degrees and two thirds had joint stiffness after conversion to...
