METALS<br />
• Uses: skeletal application<br />
skin staples<br />
suture<br />
• Biocompatability: release of ions – toxicity<br />
• Saline environment – corrosion<br />
• Oxide layer – resistance to corrosion<br />
• Corrosion – pain and tenderness, possible<br />
erythema and sinus tract<br />
STA<strong>IN</strong>LESS STEEL<br />
• Alloy – iron, nickel, molybdenum,<br />
chromium oxide.<br />
