Deep brain stimulation (DBS) surgery typically involves placement of a single lead through a burr hole, either unilaterally or bilaterally. Rare indications, however, call for placement of 2 ipsilateral leads. To date, there have been no technical descriptions of how best to secure dual ipsilateral leads to the skull. We describe a method of placing and securing 2 ipsilateral DBS leads through ...

Waste metals in the form of metal oxide (hydroxide) sludges are generated in significant amounts by the metal finishing industries, and their accumulations pose problems for disposal and challenges for recycle. The availability of technically feasible efficient separations of metals such as nickel, cobalt, chromium, cadmium, copper, tin, zinc, lead, manganese, molybdenum, and titanium from plat...

A comparative study is made of the laser damage resistance of hafnia coatings deposited on fused silica substrates with different technologies: electron beam deposition (from Hf or HfO(2) starting material), reactive low voltage ion plating, and dual ion beam sputtering. The laser damage thresholds of these coatings are determined at 1064 and 355 nm using a nanosecond pulsed YAG laser and a one...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

Background: Fractures of the distal femur are rare and severe. For an extra-articular fracture, all therapeutic options possible mini-invasive surgery can be performed. In case intra-articular open reduction internal plate fixation should Objective: To evaluate functional radiological outcomes 20 patients with comminuted supracondylar fractures managed by either single or double plating. Patien...

Colony counting by spreading bacterial suspensions on plating media by various techniques is of general concern. Comparative studies between hand plating (Drigalski-spatula technique) for different time intervals and spiral plating resulted in significant differences in colony counts. Lower counts of Gram-negative bacteria were obtained by using hand plating for more than 10s, compared with sho...

background:  there is still controversy regarding the best technique for ankle arthrodesis to acheive stable rigid fixation along with reconstructing a functional plantigrade foot. moreover, existing techniques have complictions related to stability, soft tissue covering, fusion rate, and exposure. methods: with the anterior approach exactly on the tibialis anterior sheath, the joint was expose...

PURPOSE Tibial fracture is the most common long bone fracture. Distal third tibial fractures are challenging though open reduction and plating can result in anatomical reduction and rigid fixation. This paper aimed to evaluate and compare the results of medial and lateral locking compression plates for distal third tibial fractures. METHODS This prospective clinical study involved 36 patients...
