Summary
Fibular osteotomy carries risks to nearby nerves and vessels. This study maps these structures to recommend safer surgical techniques, minimizing potential fibular osteotomy complications.
Area of Science:
- Anatomy
- Orthopedic Surgery
- Surgical Technique
Background:
- Fibular osteotomy is a common surgical procedure.
- Understanding the precise anatomical relationships between the fibula and surrounding neurovascular structures is crucial for safe execution.
- Potential iatrogenic injury to these structures can lead to significant patient morbidity.
Purpose of the Study:
- To identify and map critical neurovascular structures adjacent to the fibula.
- To assess the risk of injury to these structures during fibular osteotomy at different levels.
- To provide anatomical recommendations for optimizing fibular osteotomy techniques to minimize neurovascular complications.
Main Methods:
- Anatomical dissections were performed on five cadaveric lower extremities.
- Detailed measurements of neurovascular structures relative to the fibula were taken at 1-cm intervals.
- The fibular head's tip served as the primary reference point for all measurements.
Main Results:
- In the proximal fibula, peroneal nerves and their branches are at highest risk.
- The anterior tibial artery and deep peroneal nerve are vulnerable near the interosseous membrane.
- In the middle third, the peroneal artery and vein are the main structures at risk; distal risks are lower due to vessel branching patterns.
Conclusions:
- Fibular osteotomy should be placed as distally as feasible.
- Specific osteotomy blade trajectories are recommended for proximal, middle, and distal thirds to avoid neurovascular injury.
- These anatomical insights can guide surgeons in performing safer fibular osteotomies.
