OBJECTIVE To determine the mechanical properties of commercially available thermodynamic wires and to classify these wires mathematically into different groups. MATERIALS AND METHODS The samples examined were 48 nickel-titanium (NiTi) alloy orthodontic wires commercially available from five manufacturers. These samples included 0.016-inch, 0.016- x 0.022-inch, 0.017- x 0.025-inch, and 0.018- ...

We describe a patient who underwent arthroscopic pullout fixation for a posterior cruciate ligament (PCL) avulsion fracture. A 46-year-old female, injured in a fall while riding a motorcycle, was diagnosed with a right knee PCL tibial attachment avulsion fracture and underwent arthroscopic osteosynthesis. A Kirschner wire was drilled to a point just medial to the medial border of the anterior t...

The ideal size of intramedullary device to fix corrective osteotomy of proximal femur in abnormal bone in children and small patients may not be easily available. We report the successful use of Rush rod in combination with multiple Kirschner wires to fix the corrective osteotomy of coxa vara and shepherd crook deformity in two patients with osteogenesis imperfecta and fibrous dysplasia. The un...

Key Points  Functional orthodontic techniques have been used to correct dentofacial deformities such as parrot mouth in the young horse.  An understanding of the orthodontic principles of tooth movement and the effects of forces on bone growth will insure the best surgical outcome.  The combined approach with retention wires of the upper jaw combined with a fixed acrylic and aluminum incline...

The management of trauma has evolved greatly over the past many years. Various bone plating have been introduced for stable fixation of mandibular fractures. The present concept of treating mandibular fractures is with non-compression mini plates which relieves the patient from a hazardous intermaxillary fixation with wires and gives better stability and osteosynthesis. When placed along the Ch...

There are several important technical points that need to be observed when using an intramedullary nail to fix diametaphyseal fractures of femur and tibia. We aimed to describe a technique using 3.0-mm K wires, which act like Poller screws, in conjunction with intramedullary nails to obtain alignment of diametaphyseal fractures of the femur and tibia, and present our results. 7 distal femoral, ...

statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

Background: Patella fractures make from 0.5% to 1.5% of all bone fractures. The most common fracture type, transverse fracture, impairs knee extension mechanics due fragment displacement. In the years that followed, newer procedures were pursued in order alleviate aforementioned difficulties. K-wires successfully replaced with cannulated screws. Furthermore, cerclage wiring was alternative impl...
