Knox SPS is unique, in that it combines a protective pad on the scaphoid with a second protective pad over lower metacarpals, and it is this technology that is covered by the patent.
This is the secret to the success of the system – there must be two pads so that the hand slides when it hits the ground, eliminating the grab effect of leather during an accident. Where only one pad is used it is possible for one side of the glove to grip the ground, causing the hand to rotate, which may increase the possibility of fractures.
Knox SPS is fitted to all gloves in the Knox Hand Armour range and performance gloves by many other brands too. The granting of this patent will help to end confusion caused by glove manufacturers fitting similar-looking devices and making claims about scaphoid protective qualities. The Patent means that Knox has exclusive rights to this technology and all scaphoid protection must be either purchased or licensed from Knox.
It’s a small bone that connects the thumb to the wrist and is commonly fractured in falls, but is difficult to heal, because it only receives a limited supply of blood. Scaphoid injury is a real issue to racers and road riders alike. Kevin Schwantz actually had one scaphoid removed completely, while Neil Hodgson spent time in a hyperbaric oxygen therapy chamber, following corrective surgery on the scaphoid bone of his left wrist. Other high profile racers who have suffered scaphoid injuries are Casey Stoner and more recently Leon Camier. Many racers, including James Ellison in British Superbikes and British Superstock champion Jon Kirkham, can testify to the effectiveness of Knox SPS.
