Various materials have been used since ancient times to help immobilise fractures. In this review, we discuss the history and developments of these materials as well as plaster of Paris. There has been a recent trend away from non-operative management of fractures, and skills in the use of plaster of Paris are declining. For the successful treatment of patients, it is important to appreciate ho...

Orthopaedic casts are used to treat fractures, provide pain relief and support, and correct deformities (RCN 2000, Larsen 2002, Dandy and Edwards 2003, Nielsen and Ricketts 2005). Several different types of material are available for orthopaedic casts, including plaster of Paris, semi-rigid non-fibreglass (softcast), and a variety of resin-based synthetic materials such as rigid fibreglass. Pla...

Paris (CaS04)2H20. Excessive heat convey it into anhydrous calcium sulphate CaB^< which takes up water very slowly and does D?. harden and set. 2CaS04.2H20 = (CaSW 2H20+3H20. (CaS04)2H20 = 2CaS 04H2U, Commercial plaster of Paris is manufacture from impure gypsum and therefore contains tn impurities present in the gypsum such as alum10^ iron, silicates, carbonates, lime, etc., which be recognize...

Hexcelite and plaster of Paris below-knee walking casts were compared in a controlled clinical trial, involving 82 patients. Fewer bandage complications, problems and better comfort was found with Hexcelite compared to plaster of Paris (P less than 0.05). If all costs relating to materials, transportation, complications and extra visits due to these, were taken into account, plaster of Paris wa...

to measure soil water content (or soil matric suction) in thin layers of about 30mm, conventional gypsum blocks are not suitable. to carry out the task, mini-gypsum blocks were constructed using plaster of paris in an innovative fashion. a power relationship was found between the soil water content and the mini-gypsum blocks’ readings in kω. the calibration results showed that readings of m...

PURPOSE To evaluate the effect of particulate dentin-plaster of Paris with and without platelet-rich plasma (PRP) on bone healing and new bone formation around titanium dental implants in a canine model. Histologic sections and histomorphometric analysis of the defects were obtained at 6 and 12 weeks after surgery. MATERIALS AND METHODS Three circular bone defects were surgically prepared in ...

INTRODUCTION Plaster of Paris (PoP) impregnated bandages have been used to maintain the position of bones and joints for over a century. Classically, wool dressing is applied to the limb before the PoP, which can then be moulded to the desired shape. A modification of this practice is to wrap the PoP bandages circumferentially in cotton before wetting and applying to the patient in an attempt t...

Consensus is still lacking on how best to capture the shape of a residual limb. Computer-aided design systems have not proven more accurate, repeatable, or reliable than traditional plaster of paris methods. Research is limited in design, relates to clinical trials, and is based on opinions and clinical experience. Many outcome measurements are based on qualitative estimations of prosthetic fit...
