Retrograde femoral interlocking nail in complex fractures

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Biomedical Engineering

Background:

• Complex femoral fractures present significant treatment challenges.
• Combined injuries and specific patient demographics (obesity, pregnancy, polytrauma) complicate standard fixation methods.
• The retrograde interlocking nail technique offers a potential solution for these complex scenarios.

Purpose of the Study:

• To evaluate the efficacy and outcomes of using retrograde interlocking nails for complex femoral fractures.
• To assess the technique's applicability in various fracture combinations and patient populations.
• To determine union times, functional recovery, and complication rates.

Main Methods:

• Retrospective analysis of 35 cases with complex femoral fractures treated with retrograde interlocking nails.
• The technique involved retrograde insertion of an un-reamed, non-cannulated nail via the intercondylar notch.
• Associated fractures were managed with appropriate implants; ipsilateral femur-tibia fractures were addressed simultaneously.

Main Results:

• Average union time ranged from 12 to 18 weeks.
• 31 out of 35 patients achieved full knee range of motion.
• Complications were minimal, with one case of patellofemoral arthritis due to operative error and one malunion; no implant failures were reported.

Conclusions:

• Retrograde interlocking nailing is a viable and effective fixation method for complex femoral fractures.
• The technique allows for single-stage stabilization of multiple long bone fractures in polytrauma patients.
• It leads to early recovery, reduced hospital stays, and good functional outcomes, proving to be economical.
