- Brief summaryHallux valgus (HV) can have a great impact on the quality of life and is a frequent occurring condition. Many surgical techniques have been described to treat HV in order to improve the quality of life, over the years more than 100 different techniques or modifications are coined. In the current era the most popular and effective are the scarf osteotomy and the (modified) Chevron technique. The scarf osteotomy is popular because of its capability of correcting large IMA’s, however this procedure has some disadvantages. It is characterise by an extensive operative exposure and great technical demands. The modified Chevron osteotomy in which the caudal osteotomy is longer, has also been shown to be capable of correcting severe hallux valgus deformities. The indications for the modified chevron- and the scarf osteotomy certainly overlap, the question remains if the technically easier, more reproducible modified Chevron reaches the same result as a more difficult scarf osteotomy. By conducting this research we might be able to identify, if the modified chevron is a non-inferior operation technique than the scarf osteotomy for the correction of IMA and if it results in a lower complication rate.
