Resolving Block Screw Obstruction in Tibial Intramedullary Nailing

Area of Science:

• Orthopedic Surgery
• Surgical Techniques
• Trauma Management

Background:

• Intramedullary nail insertion can be complicated by intraoperative obstructions, such as misplaced screws.
• Tibial fractures often require intramedullary nailing for stabilization.
• Maintaining minimally invasive surgical principles is crucial in fracture management.

Purpose of the Study:

• To describe a novel, minimally invasive technique for managing intramedullary nail blockage during tibial fracture surgery.
• To present a solution for intraoperative screw obstruction during tibial nailing.
• To evaluate the efficacy and safety of the described technique.

Main Methods:

• Development of a four-step technique to address nail blockage.
• Localization of obstruction using fluoroscopy.
• Creation of a unicortical drill hole (4.5 mm) above the obstructing screw.
• Utilizing a ring handle spike instrument as a lever to advance the nail.
• Final fluoroscopic confirmation of nail position.

Main Results:

• Successful advancement of the intramedullary nail past the obstruction.
• Adequate nail placement achieved without compromising fracture reduction.
• No significant increase in operative time.
• Preservation of the minimally invasive nature of the procedure.

Conclusions:

• The described four-step technique provides an effective solution for intramedullary nail blockage during tibial fracture operations.
• This method allows for successful nail placement while maintaining fracture reduction and minimally invasive principles.
• The technique is a valuable addition to the armamentarium for managing complications in tibial nailing.
