Treatment of Cavitary Bone Defects in Chronic Osteomyelitis: Biogactive glass S53P4 vs. Calcium Sulphate Antibiotic Beads
Aim: To evaluate the efficacy of bioglass (BAG-S53P4) in the treatment of patients with chronic osteomyelitis and compare the results with calcium sulphate antibiotic beads in one medical centre. Methods: Retrospective analysis of 25 cases. INCLUSION CRITERIA patients diagnosed clinically and radiographically of osteomyelitis and treated surgically (Group 1: cavitary bone defects treated with...
متن کاملModelling of calcium sulphate solubility in concentrated multi-component sulphate solutions
The chemistry of several calcium sulphate systems was successfully modelled in multi-component acid-containing sulphate solutions using he mixed solvent electrolyte (MSE) model for calculating the mean activity coefficients of the electrolyte species. The modelling involved the tting of binary mean activity, heat capacity and solubility data, as well as ternary solubility data. The developed mo...
متن کاملEffect of liquid humus and calcium sulphate on soil aggregation
An Ultic Haploxeralf soil collected from ridges built into the slopes of the Coastal Mountain Range of Central Chile was used in applications of humic and fulvic acids (HFA) extracted from sludge from sewage treatment plants, in combination with gypsum (CaSO4). A total of 12 treatments were applied by combining four doses of HFA (0, 20, 30 and 40 t ha-1) with three doses of gypsum (0, 1.2 and 6...
متن کاملUltrasonic sound speed analysis of hydrating calcium sulphate hemihydrate
This article focuses on the hydration, and associated microstructure development, of b-hemihydrate to dihydrate (gypsum). The sound velocity is used to quantify the composition of the fresh slurry as well as the hardening and hardened—porous—material. Furthermore, an overview of available hydration kinetic and volumetric models for gypsum is addressed. The presented models predict the sound vel...
متن کاملBiodegradation and biocompatability of a calcium sulphate-hydroxyapatite bone substitute.
An injectable material consisting of calcium sulphate mixed with hydroxyapatite was investigated as a possible alternative to autograft in the restoration of bone defects. The material was studied both in vitro in simulated body fluid (SBF) and in vivo when implanted in rat muscles and into the proximal tibiae of rabbits. Variation in the strength and weight of the material during ageing in SBF...
