Orchid Orthopedic Solutions has developed a form of 17-4ph stainless steel which, following initial testing, increases the impact strength by up to 5 times and vastly improves its corrosion resistance, whilst maintaining all other properties, such as tensile strength and hardness. This is anticipated to make broaches and rasps safer for the patient, more reliable for the surgeon and reduce overall costs for the provider by maintaining the cutting edge for longer and thus increasing its serviceable life.
