Summary
This study introduces a technique for femoral lengthening using the PRECICE nail, simplifying surgery and preventing complications. This method ensures successful limb lengthening without significant discrepancies or issues like nonunion or infection.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Limb length discrepancies necessitate long bone lengthening procedures.
- Expandable intramedullary nails have revolutionized treatment.
- Current endomedular nailing techniques can be technically demanding.
Purpose of the Study:
- To describe a technical modification using the PRECICE system for femoral nailing and fixation.
- To simplify the femoral nailing and fixation process.
- To reduce technical challenges in limb lengthening procedures.
Main Methods:
- A case series of XX patients undergoing limb lengthening with the PRECICE nail.
- Utilized partial osteotomy with a Gigli saw.
- Performed nail advancement and fixation prior to complete osteotomy.
Main Results:
- 18 consecutive femoral lengthening operations were performed.
- No significant lower limb length discrepancy was observed.
- No rotational deformities, nonunion, infection, or material failure were reported.
Conclusions:
- The described technique simplifies the PRECICE nail procedure.
- This modification may minimize complications in limb lengthening.
- Magnetic expandable nails are confirmed as a gold standard, with potential application to other systems.
