Interlocking intramedullary nailing is currently the preferred treatment for most tibial fractures requiring operative treatment, with good results and a relatively low complication rate as reported in large clinical series. However, vascular and neurological complications caused by interlocking screws have been reported. In addition, insertion of distal interlocking screws can be technically d...

PURPOSE To compare immediate interlocking nailing with external fixation followed by delayed interlocking nailing, for Gustilo type IIIB open tibial fractures. METHODS 23 patients with Gustilo IIIB open tibial fractures were treated with either immediate unreamed interlocking nailing (n=9) or external fixation followed by delayed unreamed interlocking nailing (n=14). Patient age, sex ratio, f...

In this paper, we present a method and an associated tool suite for formal verification of the new ETCS level 2 based Danish railway interlocking systems. We have made a generic and reconfigurable model of the system behavior and generic high-level safety properties. This model accommodates sequential release – a feature in the new Danish interlocking systems. The generic model and safety prope...

In this project the verification of safety conditions for the control of a railway interlocking system written in ladder logic is carried out. All translation steps have been implemented and tested for a real-world example of a railway interlocking system. The steps in this translation are as follows: 1. The development of a mathematical model of a railway interlocking system and the translatio...

conclusions the functional outcome 22 months post injury showed that although primary treatment method uses locked imn in humeral shaft fractures, unlocked imn can be used in appropriate cases. less injury risk to the axillary and radial nerve, short period of surgery, and less radiation can be considered as advantages of this technique. introduction although intramedullary nailing (imn) is use...

In this paper we present a verification strategy for signalling principles for the control of a railway interlocking system written in ladder logic. All translation steps have been implemented and tested on a real-world example of a railway interlocking system. The steps in this translation are as follows: 1. The development of a mathematical model of a railway interlocking system and the trans...

Interlocking of the zygapophysial joints of the lower cervical spine may occur on one or both sides. This paper reports thirty-seven cases of unilateral interlocking (hemiluxation). In the literature unilateral interlocking is usually regarded as a form of dislocation, a term which includes other types of displacement as well. Thus, in the oldcr literature, the term dislocation often refers to ...

Reamed intramedullary nailing was carried out on R57 Gustilo grade-IIIB tibial fractures in 55 patients. After debridement, there was substantial bone loss in 28 fractures (49%). The mean time to union was 43 weeks (14 to 94). When there was no bone loss, the mean time to union was 32 weeks; it was 45 weeks if there was bone loss. Fractures complicated by infection took a mean of 53 weeks to he...
