There are different forms of applying the cast for this type of fractures, but there is no conclusive data to indicate that one method (long versus short plaster casts, double thickness against reinforced single thickness, single reinforcing ridges ) is superior to other. Nevertheless, the plaster cast has a form (shape) that distributes the material in a special form to get more resistant in some directions, so it is anisotropic. Thus, it is able to resist forces in any direction with the same strength. Several studies suggest that this treatment achieves similar clinical results to surgery in patients older than 60 years, emphasizing the high number of patients treated conservatively in common practice.Īlthough some new materials have been developed, plaster cast remains the gold standard and the most frequently used form of immobilization. Ĭonservative treatment, namely immobilization without surgery, is the most commonly applied treatment in this type of fractures. Ninety percent of them are extraarticular, known as Colles’ fractures. ConclusionĪpplying a splint before circular bandage for plaster casts used for distal radius fractures make them more resistant to usual forces.ĭistal radius is the location for one-sixth of the whole body fractures. Data confirms that applying a splint before circular bandage offers more mechanical resistance to the cast in flexion, with the same weight. No other study regarding strength and configuration of circular casts for distal radius fractures immobilization has been previously published, leading to a high variability in construction among orthopedic surgeons. The previously splinted prototypes (group S) obtained higher tensile strength with the same weight ( p < 0.05). Three-point flexural tensile strength and maximum deflection were measured and compared. Five prototypes of each group were built and mechanically tested. Group C was applied only with circular bandages (three units) and group S with a splint (one unit) and over it, a circular bandage (two units). Two frequently used configurations of circular plaster cast (with and without a splint) were selected to compare. Although conservative treatment with circular plaster cast is the most commonly used method in distal radius fractures, the best method to apply it remains unclear.
