BACKGROUND Up to 30% of patients suffer from long-term functional restrictions following conservative treatment of distal radius fractures. Whether duration of cast immobilisation influences functional outcome remains unclear. METHODS/DESIGN The aim of the study is to evaluate whether the duration of immobilization of non or minimally displaced distal radial fractures can be safely reduced. W...

some manufacturers claim to have produced new irreversible hydro-colloids that are able to maintain their dimensional stability during storage. the present study evaluated the effect of storage time on dimensional stability of three alginates: hydrogum 5, tropicalgin and alginoplast.in this experimental in-vitro trial, a total of 90 alginate impressions were made from a dentoform model using hy...

BACKGROUND The symmetrical Lyon brace is a brace, usually used to maintain correction after a plaster cast reduction in the Cotrel's EDF (Elongation-Derotation-Flexion) frame. The new Lyon brace or ARTbrace is an immediate corrective brace based on some of the principles of the plaster cast which are improved due to advances in CAD/CAM technology. The aim of this paper is to describe concepts o...

Pressure on the sole of the foot inside three different types of plaster cast, used in treatment of fracture of the lower leg, was measured on six normal persons. No significant difference was found between these pressures in below-knee plaster, full length plaster including the thigh and patellar-tendon-bearing plaster. Only occasionally a relief in pressure was found in patellar-tendon-bearin...

M a i n r e s u l t s 44 studies (3193 mainly female and older patients with 3197 fractures) with 23 different comparisons met the selection criteria, with follow-up ranging from 6 weeks to 10 years. Summarizing the outcomes was impeded by the poor quality and variation in study methods, interventions, patient characteristics, and outcomes. Some anatomic and functional outcomes (Table) were bet...

PURPOSE To compare two different impression techniques for implants in totally edentulous patients. MATERIALS AND METHODS A total of 38 patients had impressions taken both using plaster and splinted vinyl polysiloxane (splinted-VPS). Two casts per patient were generated and allocated as test (plaster) and control (splinted-VPS) cast groups according to a randomised cross-over design. One of t...

The aim of this study was to assess the usefulness of the cast index and an indigenously developed gap index as measures of poor moulding of plaster. Twenty cases of re-manipulation of distal third radius fractures in children excluding growth plate injuries were compared with a control of 80 patients. A significant difference (<0.001) was observed in the cast index and the gap index of both th...

The objective of this study was to determine whether immediate mobilisation and unprotected weight-bearing of rigidly internally fixed fractured ankles had a significant effect on ankle function or whether it predisposed the ankle to loss of reduction or hardware failure. Twenty five patients with operated Weber A/B/C fractures were allowed immediate full weight-bearing without a plaster and we...

Method The first concept is the mathematical model of circled helicoid. In the torso column, the generating circle is perpendicular to the axis. To obtain a torso column in the opposite side of scoliosis, the superposition of three electronic instantaneous full 3D moldings are necessary: First molding in self active axial elongation for pelvis and shoulders Second molding in lumbar shift and ph...
