Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Surgical Instrumentation

Background:

  • Closed interlocking intramedullary nailing is a standard orthopedic procedure.
  • Fluoroscopic control is typically required for precise proximal and distal screw insertion.
  • Direct fluoroscopic guidance for distal screw placement can be time-consuming and involves radiation exposure.

Purpose of the Study:

  • To describe a novel intramedullary nailing system that negates the need for direct fluoroscopic control during distal screw insertion.
  • To present the SG interlocking intramedullary nail system and its unique mechanism for distal fixation.

Main Methods:

  • Development and description of the SG interlocking intramedullary nail.
  • Utilizing a transversely placed guide pin for accurate distal screw localization and fixation.
  • Employing imaging solely for final alignment and instrumentation placement confirmation.

Main Results:

  • The SG interlocking intramedullary nail successfully achieves distal screw location and fixation without direct fluoroscopic guidance.
  • Imaging is minimized to confirmation of alignment and final placement, streamlining the procedure.

Conclusions:

  • The SG interlocking intramedullary nail system offers a viable alternative for distal screw insertion in closed interlocking intramedullary nailing.
  • This technique has the potential to improve surgical efficiency and reduce fluoroscopy time during orthopedic procedures.
