Novel Approach for Closed Femoral Shortening Osteotomy with Deformity Correction Using Reverse Planning and...

Area of Science:

• Orthopedic surgery
• Limb reconstruction surgery
• Traumatology

Background:

• Leg length discrepancy (LLD) is a common orthopedic condition.
• Current management involves limb lengthening or shortening, gradually or acutely.
• Simultaneous femoral shortening and deformity correction using a retrograde nail is not well-documented.

Purpose of the Study:

• To describe a novel retrograde femoral shortening technique.
• To enable simultaneous deformity correction over an intramedullary nail.
• To present a reproducible surgical method for LLD management.

Main Methods:

• Utilized a modified Baumgart reverse-planning method for preoperative planning.
• Replicated planned guidewire position intraoperatively.
• Performed percutaneous femoral shortening osteotomy with intramedullary nail insertion and controlled alignment.

Main Results:

• Successfully demonstrated a reproducible retrograde technique for femoral shortening osteotomy.
• Achieved concurrent deformity correction during the shortening procedure.
• The technique allows for simultaneous correction over an intramedullary nail.

Conclusions:

• The described retrograde technique is a safe, straightforward, and effective option for LLD treatment.
• This method addresses both leg length discrepancy and associated femoral deformity.
• It offers a novel approach to combined femoral shortening and deformity correction.
