conclusions the fixator-assisted lengthening plate technique helps to maintain the stability and alignment at both sides of an osteotomy during tibial elongation. it allows the early removal of the external fixator immediately after lengthening is completed. this technique can be applied in children with open physes and in patients with a narrow medullary canal who are unsuitable for limb lengt...

Abstract Introduction Anterior subcutaneous internal fixator(INFIX) was proposed to treat anterior pelvic ring injury. INFIX initially designed as an alternative the external fixator, but recently its indications have been expanded, using it a definitive treatment, and multiple complications reported. Methods Retrospective study of 11 polytrauma patients with fractures treated fixator after hig...

OBJECTIVE To establish an optimal single hinge axis position for application of hinged external fixation to the elbow joint. DESIGN Cadaveric biomechanical investigation. SETTING A customized motion transducer applied passive elbow motion to six cadaveric upper extremities. The instant rotation axis of the humero-ulnar articulation was determined from three-dimensional kinematic data acquir...

Compression was evaluated in an intramedullary hindfoot arthrodesis cadaver model using an external fixator and a "second generation" intramedullary compression nail. Four cadaver specimens were used. Four trials were done with each specimen. Trial 1: manual compression with the 1st generation nail. Trial 2: external fixator for compression with the 1st generation nail. Trial 3: external fixato...

BACKGROUND There are many techniques that are used for limb lengthening. Lengthening a limb over a plate is an alternative choice used in children or when using an intramedullary nail is difficult. OBJECTIVES In this study, we presented a new technique for tibial lengthening using a monolateral external fixator over a lengthening plate. MATERIALS AND METHODS For tibial lengthening, a monola...

UNLABELLED Stabilization of fractures by external fixator is based on the mechanical connecting of the pins, screwed into the proximal and distal bone fragment. Site of fracture is left without any foreign materials, which is essential for prevention of infections. Aim of this work is to compare stability of constructs bone model-external fixators of different types (Ortofix, Mitković, Charnele...

The paper presents chosen results of research on the lumbar-chest part of spine and the spine-fixator complex. Spines were gathered from cadavers. Both damaged and undamaged spines with and without fixator were investigated. Two types of fixator were used: a CD and a modified Zespol fixator (our idea)--marked as P. In the research, compression/distraction forces were applied. The analysis is ba...

  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 ...

INTRODUCTION External fixation is the primary choice of temporary fracture stabilisation for specific polytrauma patients. Adequate initial fracture healing requires sufficient stability at the fracture site. The purpose of this study was to compare the rigidity of the Dynafix DFS(®) Standard Fixator (4 joints) with the Orthofix ProCallus Fixator(®) (2 joints), which differ in possibilities for...
