OBJECTIVES Biodegradable poly L-lactic acid (PLLA) fixators used in the repair of meniscal tears may cause adverse reactions inside the knee due to delayed degradation. This study was designed to determine the reasons for late degradation of PLLA fixators. METHODS Three unused and three used meniscal PLLA fixators (BioStinger) were analyzed. The latter were removed from three patients due to ...

Five configurations of the Ilizarov fixator were analyzed in vitro. The overall stiffness, shear stiffness, and axial motion of the fracture site were determined. The data were compared with the results of eight conventional one-half frame fixators previously tested in the same manner. The Ilizarov fixator allowed significantly more axial motion at the fracture site during axial compression tha...

External fixators include pins and wires placed by surgeons to stabilize fractures such as those involving the tibia. In critical care, external fixators are more commonly used to stabilize cervical spine fractures. Because halo fixators secure cervical alignment, these devices allow early mobilization and shortened stays. However, halo-fixator complications include cranial pin loosening, local...

Complex fractures of phalangeal bones in the hand are difficult to treat. External fixation is an effective method of treatment particularly when internal fixation is not possible due to comminution and associated soft tissue injury. A variety of commercial fixators are available for the treatment of hand fractures. However, these fixators are costly and need a sufficient degree of expertise an...

This paper focuses on the probabilistic numerical solution of the problems in biomechanics and mining. Applications of Simulation-Based Reliability Assessment (SBRA) Method are presented in the solution of designing of the external fixators applied in traumatology and orthopaedics (these fixators can be applied for the treatment of open and unstable fractures etc.) and in the solution of a hard...
