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 retrospective...

BACKGROUND Femoral shaft fractures are common in adult population due to vulnerability to road traffic accident and firearm injuries. There are various treatment modalities to treat the femur shaft fracture, i.e., Plating & screws, Intramedullary nailing, External fixator and Interlocking nails. Comminuted fractures due to gun shot injuries are a challenging problem for orthopaedic surgeons. Th...

Broken screws after interlocking nailing of long bones are commonly seen in Orthopaedic practice. Removal of such screws can be difficult particularly the distal part which is often held within the bone. We describe a simple technique of using Steinman pin to aid removal of broken screws in a case of non-union fracture tibia with broken interlocking nail and screws. Steinman pin being easily av...

Our clinical experience with interlocking detachable coils for the embolization of high-flow dural arteriovenous fistulas is reported. Interlocking detachable coils are useful for transarterial and transvenous embolizations of dural arteriovenous fistulas because (a) immediate coil detachment is possible, (b) the coils can be replaced easily, (c) detached coils rarely migrate, and (d) fewer int...

Social capital designs the ensemble of resources which are accessible to a social actor through its relationship with other actors [1]. As such, social capital is always embedded in a social network, where nodes represent actors (e.g. individuals, political groups, associations), and links represent relationships (e.g., friendship, common interests, hostility) [2]. Social networks are inherentl...

The framed structure infilled with a mortarless brick (MB) panel exhibits considerable in-plane energy dissipation because of the relative sliding between bricks and good out-of-plane stability resulting from the use of interlocking mechanisms. The cyclic behaviors of MB are investigated experimentally in this study. Two different types of bricks, namely non-interlocking mortarless brick (N-IMB...

T o a large extent, the eld of “molecular machines” started aer several groups were able to prepare reasonably easily interlocking ring compounds (named catenanes for compounds consisting of interlocking rings and rotaxanes for rings threaded by molecular laments or axes). Important families of molecular machines not belonging to the interlocking world were also designed, prepared and studied ...

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...
