Summary
Fasciocutaneous flaps effectively restore functional gait in plantar foot reconstructions, demonstrating robust weight-bearing capabilities. Patients adapt by minimizing shear forces, ensuring flap integrity during walking.
Area of Science:
- Microsurgery
- Reconstructive Surgery
- Biomechanics
Background:
- Microsurgery enables free tissue transfer for plantar foot defects.
- Fasciocutaneous flaps are a reconstructive option, but their weight-bearing function is unstudied.
- This study evaluates fasciocutaneous flap performance during dynamic walking.
Purpose of the Study:
- To assess the functional weight-bearing capabilities of fasciocutaneous flaps in plantar foot reconstruction.
- To investigate the dynamic loading performance of these flaps during gait.
Main Methods:
- Instrumented gait analysis of 6 reconstructed feet and their contralateral normal feet.
- Evaluation of time-distance parameters, ground reaction forces, and plantar pressure distribution.
- Statistical comparison using t-tests after anthropometric normalization.
Main Results:
- Reconstructed feet exhibited decreased walking velocity, shorter step length, and reduced single limb support.
- Increased double limb support and swing time were observed in patients with reconstructed heels.
- Flaps demonstrated significant vertical loading and high pressure tolerance, confirming weight-bearing capacity.
- Gait adaptations led to reduced anterior-posterior shear forces, preserving graft integrity.
Conclusions:
- Fasciocutaneous flaps are effective for functional gait restoration in plantar foot defects.
- Patients naturally adopt gait patterns that minimize shear forces on the reconstructed area.
- These flaps are a viable reconstructive option for plantar soft-tissue defects.
