[Lateral osteotomy of the calcaneus in the treatment of Müller-Weiss disease].

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.
