Technical errors during intramedullary nail insertion are not uncommon. We report a case of tibial guide wire penetration into the distal tibial articular surface, the talus and the calcaneus during insertion of the nail with the ankle dorsiflexed. This has not been reported in the past. Computerized tomogram was a useful tool in the diagnosis. This complication was associated with long-standin...

BACKGROUND During lead implantation, venous access is generally achieved by puncturing the subclavian or axillary vein. Sometimes, although rarely, after lead positioning, the lead must be changed because of its inadequate mechanical stability or poor pacing parameters. This report concerns a technique of lead exchange that avoids an additional vein puncture. METHOD The tip of the lead, that ...

We construct an integral representation for the momentum space Green’s function for a Neutron in interaction with a straight current carrying wire. PACS numbers: 11.30.Pb, 03.65.Fd, 11.10.Ef ∗This research was supported in part by the Brazilian Research Agencies CNPq and Finep. 1 Consider an electrically neutral spin 1/2 particle of mass M and a magnetic moment μ~σ (a Neutron) in interaction wi...

Hyperdontia presents as an odontostomatologic derangement where and excess in tooth number is observed. Mesiodens the premaxilla is most commonly occurring supernumerary tooth. It usually clinical form. The following case reported with erupted consequences and management has been discussed elaborate details. Keywords: Mesiodens, Supernumerary tooth, Cephalometrics, Preadjusted edgewise.

statement of problem: some vertical changes might be observed during the first stage of orthodontic treatment, aligning and leveling. purpose: the aim of this study was to evaluate dental and/or skeletal vertical changes occurring in the first stage of preadjusted orthodontic treatment. materials and methods: fourteen patients with an average age of 14.1 years were selected for this study. prea...

The purpose of this study was to compare the effects of active and passive lacebacks on antero-posterior position of maxillary first molars and central incisors during leveling phase. Twenty-three subjects with Class I and Class II malocclusion were treated with first premolars extraction using preadjusted appliances (MBT 0.022-inch brackets). The leveling phase was performed with stainless ste...
