ABSTRACT
Classically, internal fixation of bones has been performed using metallic devices. However, metals are much more rigid than bone itself. Rigid fixation inhibits callus formation [1], leading to bone atrophy due to stress protection [2,3]. Metallic implants may also harbor infection which is difficult to eradicate without implant removal. Metals that are commonly used include stainless steel and titanium, and vitalium to a lesser extent. Stainless steel, however, has low resistance to corrosion. Titanium has also been shown to ‘‘degrade,’’ and it has been found in the soft tissues surrounding titanium plates and also in the regional lymph nodes.
