The cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. The results of this study explain how anterior lumbar discectomy and interbody fusion (ALIF) affects the torsional stability of the motion segment. The pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (ALIF)...

Although articulated cement spacers are frequently used in a staged approach of an infected total knee arthroplasty (TKA), no data are available on the incidence and type of spacer-related problems in these patients. A retrospective analysis of 154 patients who underwent a two-stage revision procedure for an infected TKA was performed. All patients received an articulating cement spacer at the ...

Background and Aim: Inappropriate transfer of pressure during final impression making in fabrication of complete denture can result in ridge resorption. This study aimed to assess the effect of vent size and spacer thickness on pressure produced during maxillary edentulous impression making by different impression materials in vitro. Materials and Methods: This experimental study was carried...

OBJECTIVE To verify the efficacy, side effects, and cost of treatment of acute asthma attacks, using different inhaler devices. METHODS This is a randomized, double-blind, placebo-controlled study. Salbutamol was administered via a nebulizer, a metered-dose inhaler (attached to a commercially available spacer device), a homemade non-valved spacer device, or a dry powder inhaler. Assessments w...

By introducing a thin ZnO layer as an optical spacer, we have demonstrated that inserting this layer between an active layer and a reflective electrode results in a re-distribution of the optical electric field inside bulk heterojunction solar cells. A theoretical analysis by optical modeling showed that the thin ZnO layer could shift the position of the maximum of the electric field into the a...

it is difficult to reconstruct an alar defect with cartilage involvement. here in the authors report a case of traumatic alar loss during childhood in which an alar reconstruction was carried out with a composite auricular graft put over the pedicle buccal flap which was rotated and passed through the intraoral side. the lining skin and auricular cartilage for the flap was obtained from the aur...

We assessed the intermediate functional results of eight patients after wide resection of the proximal humerus for malignant bone tumour. We used a free vascularised fibular graft as a functional spacer and a sling procedure to preserve passive scapulohumeral movement. Scapulohumeral arthrodesis was not carried out. Five patients had osteosarcoma, two achondrosarcoma and one a malignant fibrous...

The purpose of the study was to compare the recovery of knee mobility after two-stage revision of an infected total knee arthroplasty using a static or mobile spacer. At 12 months follow-up, none of the patients had a recurrent infection of their new prosthesis. Knee flexion was lower in the static spacer group at 3, 6 and 12 months postoperatively. Patients that received a mobile spacer had a ...

Bone is a complex natural material with outstanding mechanical properties and remarkable self-healing capabilities. The mechanical strength is achieved by a complex structure of a mineral part comprising apatitic calcium phosphate crystals embedded in an organic matrix. Bone also contains several types of cells constantly replacing mature bone with new bone. These cells are able to seal fractur...
