AI Article Synopsis
- Surgeons are increasingly using locking plate systems for distal radius fractures, but there are concerns about insertion errors leading to removal difficulties.
- Recent cases highlight complications from titanium implants, including issues like integration with bone and binding between screws and plates.
- The text discusses important terminology related to these problems, such as cold-welding and fretting, emphasizing that even with proper technique, removing titanium implants can be complicated by in situ reactions.
Article Abstract
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.
