Incorrect or delayed diagnosis and treatment of the carpometacarpal fracture-dislocations is often associated with poor prognosis. We present a rare case of unusual pattern of injury, involving dorsal dislocation of four ulnar carpometacarpal joints, associated with fracture of the trapezium, a burst fracture of the trapezoid  bone and an extra-articular fracture of the third distal  of the rad...

BACKGROUND The purpose of the study is to assess the antiadherent and antibacterial properties of surface-modified stainless steel and NiTi orthodontic wires with silver against Lactobacillus acidophilus. METHODS This study was done on 80 specimens of stainless steel and NiTi orthodontic wires. The specimens were divided into eight test groups. Each group consisted of 10 specimens. Groups con...

Background: Orthodontics is a part of dentistry that includes preventive methods and correction of dental irregularities that need to be repositioned by functional and mechanical tools to provide an ideal occlusion and a beautiful face for patients. There are currently four metal arch wires used in orthodontic treatment: stainless steel alloy, cobalt-chromium alloy, nickel-titanium alloy, and b...

Transcranial Magnetic Stimulation, or TMS, is a technique in which a brief electrical current passes through a coil of wires, thereby generating a strong magnetic field that is perpendicular to the axis of the coil. The magnetic field can pass through tissues such as skin, muscle, and bone and extend into the brain. The rapidly rising and falling magnetic field generates a brief electrical disc...

When NiTi powder compacts containing Nb wires are heated above 1 170 8C, each Nb wire reacts with adjacent NiTi powders to form a eutectic liquid which wicks into the space between the remaining NiTi powders. This creates a macropore at the location of the Nb wire while eliminating the microporosity between NiTi powders which is filled with a NiTi/Nb eutectic phase after solidification. This no...

We report a 15-year-old girl who underwent a mid-carpal fusion for undiagnosed impaction-fractures of the capitate, lunate, and triquetrum after a fall on her outstretched left hand in a dorsiflexed and radially deviated position. The joint was dis-impacted, and the height of the lunate was restored using a cortical bone graft. The damaged proximal capitate articular surface was decorticated to...

Porous titanium with elongated and aligned pores, mimicking the anisotropic structure of bone, was created by solid-state expansion of argon trapped in elongated pores between titanium wires. Both elastic moduli and yield strengths are larger in the longitudinal direction (E = 51 GPa, sigma y = 338 MPa) than in the transverse direction (E = 41 GPa, sigma y = 267 MPa). Finite-element analysis of...

to check the normal alignment of the fractured bone Fracture of Radiusulna and Tibiafibula is more fragments. Postoperative treatment followed for 5 common in dogs. Road traffic accidents are the days that is injection Cefazolin sodium at the dose rate principal cause of compound and complicated fractures of 20mg/ kg body weight daily. The k-wires entry and of these bones in canines due to less...

External fixation for the purpose of bony realignment has been in practice since the early 1900s and is widely used today. External fixators are primarily used for trauma but may also be used for deformity correction and arthrodesis, among other applications. The advantages of external fixation over open reduction and internal fixation and intramedullary nailing include simplicity of applicatio...

The purpose of this study was to evaluate and compare the force levels of aesthetic Ni-Ti wires to regular Ni-Ti wires of the same dimension and evaluate their mechanical properties. Aesthetic and regular maxillary superelastic Ni-Ti wires (0.016 × 0.022) from four different manufacturers (G&H Wire Company, TP Orthodontics, GAC International, and Ortho Organizers) were selected and grouped I-IV...
