Hallux rigidus is the result of a degenerative process of the metatarsophalangeal joint of the hallux. In the intermediate stages there are controversies in the type of treatments and different types of osteotomies can be performed. Objective. To analyze cases of moderate grade hallux rigidus that have undergone surgery at out center with a chevron-type modified osteotomy. Material and methods. We conducted a retrospective study between January 2013 and December 2015 of 21 hallux rigidus with a minimum follow-up of 12 months. To evaluate the results we used the AOFAS questionnaire and the visual analogue scale (VAS). At the end of the follow-up we also conducted a satisfaction questionnaire. Results. The postoperative results show a considerable increase in the average mean of the AOFAS questionnaire from 61,3 before surgery to 92,1 at 12 months after surgery. The VAS improved 6 points and 18 patients were very satisfied with the results. There were no cases of nonunion, avascular necrosis, MTF stiffness, failed implants or infection. No patient was reoperated. Conclusion. We believe that our technique can be useful nowadays. This technique is easy to perform and reproducible.
