This article describes factors affecting the accuracy of transpedicle screw placements performed with the Renaissance robot-guided system and reviews the relevant literature. Between January 2013 and January 2015, Renaissance robot-guided spinal surgery was performed in 125 patients at Kaohsiung Medical University Hospital in Kaohsiung, Taiwan. The surgeries included 662 transpedicle screw impl...

PURPOSE To assess the effectiveness of Brooks' posterior stabilisation and fusion for the unstable atlantoaxial joint due to congenital dysplastic dens and trauma. METHODS We retrospectively studied records of 54 patients (36 males and 18 females; age range, 3-58 years) who underwent Brooks' posterior stabilisation procedure between March 1975 and December 1999, at the Catholic University of ...

r t 2 t t a d h C 1 l g U c t t t a w t p anagement of patients with atrophic mandible fracures has been a challenge for maxillofacial surgeons or years. Techniques that have been used are plints, external pins, split ribs wire osteosynthesis, nd rigid fixation. Results with each of these techiques have had variable success depending on the mount of atrophy that the patient underwent before nju...

OBJECTIVE To compare the hearing results in patients with otosclerosis who underwent a stapedotomy with either a platinum wire prosthesis or a commercially available, heat-activated nitinol stapes piston prosthesis. DESIGN Retrospective medical chart review. SETTING Academic tertiary care medical center. PATIENTS Seventy-nine consecutive patients diagnosed as having otosclerosis who under...

Using an osteotomy of the olecranon as a model of a transverse fracture in 22 cadaver elbows we determined the ability of three different types of suture and stainless steel wire to maintain reduction when using a tension-band technique to stabilise the bone. Physiological cyclical loading simulating passive elbow movement (15 N) and using the arms to push up from a chair (450 N) were applied u...

in this study, as for the re-casting, surface alloying and re-solidification layer of this alloys at the work piece level machining with wire electro discharge machining (wedm), changes of surface micro hardness with changes of operational parameters has been studied. therefore, study shows using surface alloying phenomena with the diffusion of wire material into the machined surface and select...

Staphylococcus comprises up to two-thirds of all pathogens in orthopaedic implant infections with two species respectively Staphylococcus aureus and Staphylococcus epidermidis, being the predominate etiological agents isolated. Further, with the emergence of methicillin-resistant S. aureus (MRSA), treatment of S. aureus implant infections has become more difficult, thus representing a devastati...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...

central venous catheterization (cvc) is a commonly performed procedure for venous access. it is associated with several complications. we report a rare case of extra luminal entrapment of guide wire during cvc placement in right jugular vein. we report a case of 28 years old female patient presented in our emergency with history of entrapped guide wire in right side of neck during cvc. x-ray sh...

he mid-frontobasal approach can be carried out with the help of several tools, thanks to the technical improvements in the neurosurgical field. Cutting thick bone is one of the drawbacks of the power saw, this needs rongeuring of the bone or the use of manual spiral wire with handle.1 The use of the Gigli saw2 requires additional time compared with power-driven drills, however, this is amply co...
