OBJECTIVE To compare ender nails and unreamed interlocking nails in a randomized clinical trial study. METHODS From March 2001 to March 2003, 131 patients with tibial fractures of the central two thirds of the tibia were admitted to the emergency ward of Shohada Hospital, Tabriz, Iran and were randomized to either an ender tibial nail or an undreamed interlocking tibial nail as their primary ...

The ability of an interlocking screw fixation technique to minimize bone loss related to stress shielding in the tibia was investigated and compared to the abilities of cement and press-fit fixation. Full bony ingrowth has been associated with greater stress shielding than partial ingrowth; therefore, the effect of intimate bonding of the stem to bone on subsequent bone loss was also studied. A...

Empirical research on world cities often draws on Taylor’s (2001) notion of an ‘interlocking network model’, in which office networks of globalized service firms are assumed to shape the spatialities of urban networks. In spite of its many merits, this approach is limited because the resultant adjacency matrices are not really fit for network-analytic calculations. We therefore propose a fresh ...

There is a perception that distal freehand interlocking (DFHI) of intramedullary nails can be difficult and time consuming. This study consists of a survey of surgeons' practices for DFHI screws and their reasons for not using this technique. A survey was sent to 1400 orthopaedic surgeons who were asked to agree or disagree with statements regarding the difficulty and indications for the usage ...

abstract  background: reamed interlocking intramedullary nailing of the tibia is a procedure  for the treatment of a non-infected tibial non::::union::::. the purpose of this clinical  study was to evaluate the outcome of this method as a treatment of tibial non::::union::::.  methods: twenty-nine patients with non::::union:::: after initial therapy for tibial fracture  were retrospectively ass...

The current study aimed to identify the degree of availability requirements digital transformation in schools Qasaba Amman from point view school principals and educational supervisors. indicators their validity reliability were verified, sample consisted (150) (45) supervisors, who chosen randomly. Infrastructure are generally high, while for rest requirements, administration, students, teache...

In order to simulate the process of homology searching and interlocking of chromosomes in meiotic pairing, a cellular automaton model is introduced. The model reflects both the spatial as well as the temporal behavior of chromosomes in the meiotic cell nucleus. Moreover, we compare the outcome of our simulations to results obtained by a stochastic model describing interlocking probabilities ana...

Aseptic non-union is a major problem following complicated fracture tibia, which carries significant morbidity and prolonged course of treatment. Plate fixation and autogenous bone grafting has been established as a method of treatment. However the risk of infection, implant failure and donor site morbidity are high. We reviewed twelve consecutive cases of established non-union tibia treated by...
