OBJECTIVE To determine the outcome of intramedullary interlocking surgical implant generation network (SIGN) nail in diaphyseal tibial fractures in terms of union and failure of implant (breakage of nail or interlocking screws). STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Orthopaedics and Spinal Surgery, Ghurki Trust Teaching Hospital, Lahore Medical and Dental College, Lahore, fr...

OBJECTIVE The aim of this article was to determine the effects of minimally invasive percutaneous plates versus interlocking intramedullary nailing in the treatment of tibial shaft fractures in adults. METHOD Literature searches of the Cochrane Library, PubMed, EMBASE, the Chinese Biomedical Literature database, the CNKI database, Wanfang Data, and the Weipu Journal database were performed up...

OBJECTIVE To compare the mechanical properties of two stabilization methods for ostectomized equine third metacarpi (MC3): (1) an interlocking nail system and (2) two dynamic compression plates. Animal or Sample Population-Ten pairs of adult equine forelimbs intact from the midradius distally. METHODS Ten pairs of equine MC3 were divided into two test groups (five pairs each): caudocranial fo...

three dimensioned finite element analysis were conducted on concrete block paving. in order to verify the calculated results, an experimental case study was analyzed. good agreement was observed between the measured and the calculated results. based on the finite element analysis results and available failure models, comprehensive design charts were developed for port and industrial pavement wh...

Petri nets have been widely applied in different aspects of railway modelling and analysis. This paper presents an insight into how coloured Petri nets can be used to model geographical interlocking. We start with a generalisation of coloured Petri nets and follow with an overview of interlocking. In the main body we present a generic unit model and demonstrate how it can be used to represent a...

A major drawback of conventional fixator system is the penetration of fixator pins into the medullary canal. The pins create a direct link between the medullary cavity and outer environment, leading to higher infection rates on conversion to intramedullary nailing. This study was designed to prospectively evaluate the role of new rapid pinless external fixators in primary stabilization of open ...

BACKGROUND Open reduction and internal fixation with a plate is deemed to represent the gold standard of surgical treatment for displaced intra-articular calcaneal fractures. Standard plate fixation is usually placed through an extended lateral approach with high risk for wound complications. Minimally invasive techniques might avoid wound complications but provide limited construct stability. ...

Railway interlocking is a safety critical system because its incorrect functioning may cause serious consequences. Modeling of a reliable interlocking has become a challenging problem due to its inherent complexity and introduction of new technologies. In this paper, formal analysis of safety properties of moving block interlocking is presented preventing collision and derailing of trains at th...
