The safe zone for external fixator pins in the femur.
OBJECTIVE To define the anatomic "safe zone" for placement of external fixator half pins into the anterior and lateral femur. METHODS In 20 fresh-frozen hemipelvis specimens, the femoral nerve and all branches crossing the femur were dissected out to their final muscular locations. The location where the nerves crossed the anterior femur was measured from the anterior superior iliac spine and...
متن کاملAn original knee arthrodesis technique combining external fixator with Steinman pins direct fixation.
INTRODUCTION Knee arthrodesis may be the last possible option for infected total knee arthroplasty (TKA) patients and in revision cases involving severe bone loss and/or extensor mechanism damages. Success in these situations depends on achieving good fixation assembly stability. We report bone fusion results using a fixation technique combining cross-pinning by two Steinman pins with a single-...
متن کاملRelationship between Rigidity of External Fixator and Number of Pins: Computer Analysis Using Finite Elements
OBJECTIVE To analyze the rigidity of a platform-type external fixator assembly, according to different numbers of pins on each clamp. METHODS Computer simulation on a large-sized Cromus dynamic external fixator (Baumer SA) was performed using a finite element method, in accordance with the standard ASTM F1541. The models were generated with approximately 450,000 quadratic tetrahedral elements...
متن کاملThe Honest Broker - Stuck Half Way Through
In their recent Nature article Pielke et al. (2008) convey as a their key message that the IPCC dramatically underestimates the socio-economic effort it would take to transform the 21 century non-policy high emission path into a policy-induced low-emission path. Thus, the core statement of working group 3 in the Fourth Assessment Report of the IPCC seems to begin to totter – that an ambitious c...
متن کاملA Method to Remove Optical Fibers Coating
In this paper we report some experimental results concerning the stripping in any portion of the optical fibers at 10.6 μm wavelength. These experimental procedures have been performed using a CO2 laser with 40 W power and a galvanometer scanner with 150 mm focal length. The objective of this paper was to find the optimal conditions (speed of the laser along the optical fiber) for a good stripp...
