Aim:
This study evaluates the pressure distribution, the radiological and clinical results in patients before surgery and 6 months after scarf osteotomy for hallux valgus.
Methods:
29 patients were examined before surgery and 6 months after surgery for symptomatic hallux valgus. Pedographic analysis was performed by dividing the footprint of the patients into 8 regions of interest. For each region the maximum mean pressure and the peak pressure were evaluated. Moreover, clinicofunctional results (AOFAS score) and radiological results were evaluated.
Results:
6 months postoperatively, maximum mean pressure increased significantly under the medial forefoot where as the peak pressure in this region revealed indifferent results. Significant improvement of clinicofunctional results and a significant reduction of the intermetatarsal and metatarsophalangeal angle could be seen.
Conclusion:
These results confirm the clinical and radiological findings of other studies, but this study shows for the first time an increase of pressure under the first ray of the foot after hallux valgus surgery and an adaptation to the pressure distribution of normal feet.
