Etiologies of Orthopedic Implant Removal Among Patients Who Underwent Orthopedic Fixation Surgeries in King Abdulaziz Medical City

Background: Hardware removal surgeries are considerably common. However, the justifications for these surgeries are debatable. The indications may vary from pain, surgical site infection, or failure of osteosynthesis. Additionally, the surgery can be performed without medical indication. Following these surgeries, many complications can occur. Therefore, surgeons and patients should be aware of the appropriate indications and have realistic expectations of the risks and benefits of implant removal. Methods: This was a retrospective chart review study. We included all patients aged 17-86 years who underwent hardware removal surgery in the orthopedic surgery department of King Abdulaziz Medical City, Riyadh, Saudi Arabia, from 2010 to 2019. All relevant data, such as demographic characteristics, location and type of hardware, indication for hardware removal, duration between insertion and removal, and complications after removal were recorded and analyzed. Results: A total of 244 medical records were reviewed with a mean patient age of 34 years. Out of the total, 190 patients (77.9%) were male. The femur was the most common location of hardware removal, in 50 cases (20.58%). Plates and screws were the most common type of implants (40.2%). Most patients underwent hardware implantation because of fractures (89.3%). In total, 119 patients (48.8%) had the hardware removed electively. Only 29 patients (12%) reported postoperative complications; 190 patients (77.9%) were advised by their surgeon against hardware removal. Conclusion: Hardware removal procedures are commonly performed worldwide for various reasons, including infection, pain, and loosening. In this study, we have outlined the reasons for implant removal, the locations, complications, and the rationale behind this surgery. We have provided a new decision-making assessment, aimed at the general population and surgeons alike, that will help patients better comprehend the complications and risks associated with this elective surgery.
