Research ArticleOpen accessPhrase in the titleStress Prediction in the Dynamic Compression Plate with Changing the Configuration of the Screw FixationBoonthum WongchaiProblem statement: Human femur fracture is one of the most frequent type of bone fractures. One of the widely used methods in an internal fixation is an application of the Dynamic Compression Plate (DCP). The configuration of the screw fixation plays a major role of the DCP stress. Approach: This research is proposed to investigate the stress distribution in the … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,618 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleThe Effect of the Configuration of the Screw Fixation on the Interfragmentary StrainBoonthum WongchaiProblem statement: The interfragmentary strain (εIF) is the important parameter for femur fracture healing. The Dynamic Compression Plate (DCP) is commonly used in femur fracture. The DCP and the fractured femur are fixed by using the conventional screws. Approach: This research is proposed to investigate the effect of configuration of the screw fixation on the interfragmentary stain by using Finite … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 15 Mar 2012 · 7,031 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of the Screw Torque Level on the Interfragmentary Strain and the Interfragmentary ModulusBoonthum WongchaiThe screw torque is applied at the screw head to fix the plate and the bone. It generates the compressive force between the plate and the bone to stabilize them. The interfragmentary strain is the main factor for healing the bone fractured. The screw torque level affects the interfragmentary strain and the stability of the fixation between the plates an … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,469 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMycobacterium Smegmatis Infection of a Lumbar Spine Instrumented FusionFrank Allen ZimbaProblem statement: To demonstrate the presentation of atypical mycobacterial postsurgical infections and their management. Approach: Single patient case report. Results: Successful management of atypical mycobacterial post operative infection with preservation of instrumented hardware posterior pedicle screw fixation and interbody cages. Conclusion: This report suggests that these atypical mycobacterial infections can be eradicated with successful outcomes with preservation of spinal instrumentation. …American Journal of Infectious Diseases, Vol. 7, Issue 1 · 27 Jun 2011 · 8,802 accessesView PDF Cite
