Objectives:
This article aims to radiographically and clinically evaluate the results of the surgical correction of hallux valgus using the scarf technique. The pre- and postsurgical hallux valgus angles - metatarsophalangeal angle (MP), intermetatarsal angle (IM), and degree of dislocation of the sesamoids - were retrospectively evaluated, as well as their clinical parameters.
Methods:
70 pre- and postoperative radiographs of patients undergoing surgical correction of hallux valgus by the scarf osteotomy technique were retrospectively evaluated. The American Orthopedic Foot And Ankle Society Score (AOFAS) was used for pre- and postoperative clinical evaluation.
Results:
There was a statistically significant improvement in the MP, IM, and sesamoid position, in addition to the clinical improvement verified by the AOFAS.
Conclusion:
Scarf osteotomy improves the MP and IM angles and correct the position of the sesamoid, as well as improve the AOFAS. Level of Evidence IV, Retrospective Comparative Study.
