Fracture Stability

Aim. To evaluate whether aseptic hypertrophic nonunion in the long bones of the lower extremity can be treated successfully with LISS applied with closed methods without grafting. Materials and Methods. The study included 7 tibias and 9 femurs of 16 patients. All cases had hypertrophic nonunion. Initial surgical treatment was with intramedullary nailing in 14 cases, 6 of which had required an exchange of intramedullary nail. All the patients were treated with LISS plate with closed methods. Results. Union was obtained at mean 7 months in all patients. No implant loosening or breakage of the implant was observed and there was no requirement for secondary surgery. Conclusion. Cases of hypertrophic nonunion have excellent blood supply and biological potential. Therefore, there is no need for bone grafting and the addition of fracture stability is enough to achieve full union. Using a limited approach and percutaneous screw insertion, LISS provides fracture stabilization with soft tissue protection.

A new approach for the detection of the step initiation in the lower extremity exoskeleton is presented. As the detection of the step initiation is the important factor for the lower extremity exoskeleton to shadow the operator’s movement as soon as possible, many studies have been done to detect it faster by using heel-off time or toe-off time. We detect the step initiation faster than other approaches with the vertical ground reaction forces. Also, we predict the first step’s heel strike time with the regression equations based on the vertical ground reaction forces as soon as we detect the step initiation. It could enable the lower extremity exoskeleton to shadow the operator’s movement much faster.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.
