Summary
Fibula resection can lead to tibial stress fractures and pain, especially when less than a quarter of the fibula remains. Preserving the distal fibula is recommended when oncologically feasible to maintain leg stability.
Area of Science:
- Orthopedic Surgery
- Biomechanical Engineering
- Radiology
Background:
- Fibula resection is performed for tumor disease or allograft harvesting.
- Post-resection complications include loss of leg stability and altered biomechanics.
- Clinical and radiological outcomes require correlation with experimental data.
Purpose of the Study:
- To correlate clinical and radiological findings after fibula resection with biomechanical principles.
- To investigate the incidence of pain and stress fractures post-fibula resection.
- To determine the impact of remaining fibula length on postoperative complications.
Main Methods:
- Retrospective analysis of twelve patients undergoing fibula resection.
- Correlation of clinical data (pain, function) with radiological imaging (X-rays).
- Review of experimental biomechanical investigations related to fibula resection.
Main Results:
- Five patients experienced lower leg pain; three developed tibial stress fractures.
- Tibial cortex thickening observed radiologically, with one case showing a 10% increase in shaft diameter.
- Complications were more frequent when the remaining fibula was less than 1/4th of the original length.
Conclusions:
- Fibula resection significantly impacts leg biomechanics, potentially causing pain and stress fractures.
- Preserving a longer distal fibula segment, if oncologically safe, may reduce postoperative complications.
- Understanding biomechanical changes is crucial for assessing patient outcomes after fibula resection.
