Abstract
BACKGROUND: Removal of previously placed orthopaedic implants is a commonly performed procedure worldwide. Given the diversity of orthopaedic implant manufacturers, surgeons may be uncertain whether they have the appropriate screwdriver on site. The purpose of this study was to assess the compatibility of screw head and size configurations from various orthopaedic manufacturers with two commonly used universal screw removal sets. METHODS: Inclusion of orthopaedic implant manufacturers was determined by market share based on industry-monitoring financial firms. Screw size and drive type for the top grossing orthopaedic implant manufacturers were collected and recorded. Screw and screwdriver compatibility was assessed and compared with two commonly used universal screw removal sets. RESULTS: In total, six orthopaedic implant companies with commonly implanted screws throughout the appendicular skeleton were included. The data were compiled in table format with noncannulated, cannulated, and locking screw offerings separated by the screw size and manufacturer. Guidewire size compatibility for cannulated offerings was also assessed. CONCLUSIONS: Given the ubiquity of implanted orthopaedic implant, removal must be as safe, planned, and controlled as possible. The data in this article provide an inclusive, centralized resource for surgeons looking to confirm the compatibility of previously implanted screws and available removal equipment at their institution.
