Titanium Integration With Bone, Welding, and Screw Head Destruction Complicating Hardware Removal of the Distal Radius: Report of 2 Cases JOURNAL OF HAND SURGERY-AMERICAN VOLUME Van Nortwick, S. S., Yao, J., Ladd, A. L. 2012; 37A (7): 1388-1392


Increasingly, surgeons treat distal radius fractures with locking plate systems. Recent case reports have focused on technical insertion errors resulting in removal difficulties: poor drilling orientation or cross-threading, destruction of the screw head, and filling of the screw recess with tissue. We report 2 complications of titanium locked plate removal secondary to in vivo reactions including titanium integration with bone and mechanical binding between the titanium screw and plate. We clarify and discuss terminology relevant to implant removal, including cold-welding, galling, fretting, and anodization. Even with optimal technique, in situ reactions can complicate titanium implant removal.
