Abstract

In my work, I examined a palmar forearm splint manufactured by a Hungarian medical device producer. Considering the test results that come from failure analysis, material composition analysis, hardness testing, macroscopic and microscopic examination, scanning electron microscopy and implemented on a product damaged under real conditions, I concluded that the medical device, returned by the customer, had broken prematurely due to improper use. The results of the fatigue test carried out as a physical simulation of the load show that the medical device can withstand more than 850 cycles of micromotion without any problems. Macrofractographic comparisons were performed between the fracture surfaces of the device returned by the users and those of that dismantled under laboratory conditions, thus confirming the validity of my measurement.
