Perioperative Contamination of Orthopaedic Polyethylene Implants, Targeting Devices and Arthroscopes. Experts' Decision Tree and Literature Review

[Ossification of the gum over intraosseal implant]

In a patient after implantation of a metal screw implant into the bone with suturing of the soft tissues above it after 6 months there was a spontaneous delimitation of the product by a thin strip of compact bone tissue, most likely formed from the bone structures damaged during the operation. Small bone fragments formed during the preparation of the implantation bed were found in the tissues as homogeneous eosinophilic deposits without inflammation and macrophage reactions.
