Stiffness of modified Type 1a linear external skeletal fixators.
Modifications of a Type 1a external skeletal fixator (ESF) frame were evaluated by alternately placing transfixation pins on opposite sides of the connecting rod (Type 1a-MOD) or by placing additional connecting rods on either of the two inside (Type 1a-INSIDE) or two outside (Type 1a-OUTSIDE) transfixation pins. The objective of this study was to evaluate the stiffness of these modifications i...
متن کاملThe role of external fixators in paediatric trauma.
We report a retrospective review of all paediatric trauma patients managed with an external fixator admitted to our institution over a 7-year period. We identified 30 fractures in 28 children. The fractures included 20 tibiae, 5 femurs, 2 humerii, 2 radii and 1 phalanx. The indications were 23 open fractures, 4 comminuted fractures and 3 closed fractures in poly-traumatised patients. It was the...
متن کاملRigidity of unilateral external fixators--a biomechanical study.
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...
متن کاملImaging of fractures with external fixators using flexible cassettes.
Manufacturers are now producing components made of radiolucent material, but these are expensive. and may not be available to all surgeons. We have used panoramic radiography products (Kodak Dental Products Catalog and Reference Guide 199 1). as used by dental surgeons for the mandible, to image fractures in some forms of external fixation (Fig. Ib). The range of products includes small films a...
متن کاملBacteria on external fixators: which prep is best?
BACKGROUND There are no established guidelines for the surgical prep of an external fixator in the operative field. This study investigates the effectiveness of different prep solutions and methods of application. METHODS Forty external fixator constructs, consisting of a rod, pin, and pin to rod coupling device, were immersed in a broth of Staphylococcus aureus (lux) for 12 hours. Constructs...
