BackgroundLong‐bone fractures are very common in trauma centers. The conventional Arbeitsgemeindschaft fur Osteosynthesefragen (AO) technique contributes to most fracture healing problems, and external fixation technology also has several disadvantages, so new techniques are being explored.
MethodA novel hexapod computer‐assisted fracture reduction system based on a 3D‐CT image reconstruction process...
BackgroundClosed reduction is of great benefit for fracture healing. However, achieving this without sacrificing the reduction accuracy and exposing the surgeon and patient to excessive radiation is difficult.
MethodsA novel parachute guiding system (ParaEx System) was developed for closed reduction of fractures based on computed tomography data. The system included two counter guides with stainless...
BackgroundThis study was conducted to examine and compare the pertrochanteric fixator (PTF) and dynamic hip screw (DHS).
MethodsAnsysWorkbench, a commercial finite element based program, was used to investigate the biomechanical parameters of femoral fractures and implants. The human femoral model was scanned and a femoral intertrochanteric fracture was created. Von Mises stress, von Mises strain,...
BackgroundDifferent hexapod‐based external fixators are increasingly used to treat bone deformities and fractures. Accuracy has not been measured sufficiently for all models.
MethodsAn infrared tracking system was applied to measure positioning maneuvers with a motorized Precision Hexapod® fixator, detecting three‐dimensional positions of reflective balls mounted in an L‐arrangement on the fixator,...
Background
Poor reduction can lead to complications such as deformity and delayed fracture healing. We introduce a 3D printed external fixator technology that can assist in fracture reduction and fixation.
Methods
A fractured long bone was first fixed by a temporary external fixator and then scanned with computed tomography. Three‐dimensional reconstruction of the contour and bone fragments of...
