Definitions

  • Known post-manufacturing processes to address these micro-particles include removal of the micro-particles by chemical etching, such as that disclosed in U.S. Application Publication No. 2006/0147332, or melting them into the main body of the porous structure, such as that disclosed by Stamp et al (J Master Sci: Mater. Med (2009) 20:1839-48). While these methods ensure that the micro-particles do not detach and harm the patient during use, they also diminish the benefits provided by these micro- particles by reducing the surface area and the asperities of the porous structure for cellular attachment.
  • a vertical normal load of 44 N (0.15 MPa) is applied to the pins made from porous structure.
  • the pins are attached to the upper fixture of the pin-on-disk machine shown in FIG. 3.
  • the machine is programmed such that the base plate rotates all bone analogue plates in an arc shaped motion path at a displacement rate of about 3.8 mm/sec.
  • Vertical and horizontal loads are sampled at 100 Hz and are then used to calculate the maximum dynamic coefficient of friction (tangential force divided by normal force).
  • FIG. 2 is a chart of the average coefficient of friction of samples of six types of products.
  • the first product was ROUGHCOAT beads, which is a commercially available porous in-growth surface. It consists of approximately 250-350 micron sized beads sintered on a solid substrate. The coefficient of friction of three samples of ROUGHCOAT beads were measured. Referring to FIG. 2, the average (+ std. dev.) coefficient of the ROUGHCOAT beads samples was about 0.55+0.08.
  • thermal treatments that are less than about 800 degrees C are insufficient to improve the attachment strength of the micro-particles, e.g. , adequately bind the loose micro-particles.
  • One exemplary way to determine whether the thermal treatment was sufficient to bind the loose micro-particles involves assessing the particle shedding of the RM structure by agitating the thermally treated samples in an ultrasonic bath containing deionized water.
  • samples to be tested are first weighed on a high-precision balance. The samples are then submerged in deionized water and subjected to ultrasonic vibration in an ultrasonic bath for an appropriate amount of time known to those skilled in the art, e.g. , 4 minutes.
