The aim of this research was to create novel computer graphics models of the human spine which can bend, flex and twist. The model aims to realistically duplicate the shape of the spine during various sitting positions adopted by patients during epidural anaesthesia and surgery. The extent of bending and flexing is kept within the limits of spine flexibility. Also the model vertebrate adapt in size and shape to match weight and height of specific patient bodies. The flexible spine model can be of benefit to epidural simulators which require accurate models of spinal vertebrae for needle insertion procedures.
