Introduction:
The deforming condition of the navicular bone known as Müller-Weiss disease (MWD) is a rare disease. Patients present with chronic pain in the talonavicular joint and a paradoxical flat foot with a varo hindfoot.
Objective:
To analyze the clinical results of a lateral osteotomy of calcaneus applied to patients with MWD.
Material and methods:
Retrospective observational study carried out in two hospitals. The series consists of nine cases in eight patients, all of them with symptomatic Müller-Weiss disease, treated by lateral osteotomy of the calcaneus between 2012 and 2017, obtaining an average follow-up of 4 years (2-6). The mean age was 62 years (50-75). In all patients, Costa-Bartani angles (CB), Kite angle and Calcaneal Inclination (CI) were measured. In addition, the Manchester Oxford Scale (MO) to measure the post-surgical satisfaction of patients.
Results:
All patients report having improved their pain by obtaining a postoperative score on the mean Manchester Oxford scale of 32.54 points (15.62-53.75). In 66% of patients the CB angle improves, the Kite angle in 89% and the CI in 33%.
Conclusion:
The improvement in the pain of the patients in our series is not accompanied by radiological changes in the same proportion, it is a simple and uncomplicated technique in our follow-up.
