A Comprehensive Guide to Tibial Nailing Systems for Short Segment Nailing Procedures

Area of Science:

• Orthopedic biomechanics
• Surgical implant technology

Background:

• Short segment fixation of tibial fractures often utilizes intramedullary nailing.
• Variability in available tibial nail systems necessitates a clear understanding of their specifications.

Purpose of the Study:

• To systematically characterize and compare interlocking screw configurations and design specifications of commercially available tibial intramedullary nail systems in the United States.
• To provide a resource for surgeons selecting implants for short segment tibial fracture fixation.

Main Methods:

• A comprehensive review of publicly available product information from US-marketed tibial intramedullary nail systems was conducted.
• Data on interlocking screw hole quantity, position, nail diameter, length, and design features were collected from 13 systems across 10 manufacturers.
• Direct communication with manufacturers supplemented publicly available data.

Main Results:

• Significant variability was observed in interlocking screw configurations, with 3 to 5 proximal and 3 to 5 distal screws available across systems.
• Differences in screw number, spatial distribution, nail diameter, and length were noted.
• The shortest proximal distance to the second screw hole was 17mm, and the shortest distal distance was 12mm.

Conclusions:

• The study offers a detailed comparison of tibial nailing systems, highlighting variations in nail specifications and screw positions.
• A comprehensive table and graphic representation can aid surgeons in operative planning for short segment distal tibial fractures.
• This information supports the selection of optimal implants for personalized patient care in tibial fracture management.
