Müller-Weiss Disease: Midfoot Arthrodesis in Reduction vs Malreduction.

BACKGROUND

Midfoot arthrodesis is regarded as the main surgical approach for treating Müller-Weiss disease (MWD). This study aimed to investigate the incidence of postoperative pain during MWD treatment through midfoot reduction or malreduction during arthrodesis and to explore the factors influencing postoperative pain in patients with MWD.

METHODS

A total of 67 patients with MWD were recruited and divided into two groups according to whether midfoot alignment was reduced: reduction group (

RESULTS

The reduction group exhibited better clinical and radiological parameters, including the TMT1dp and medial navicular pole extrusion, than the malreduction group at the last follow-up (all

CONCLUSION

Midfoot reduction arthrodesis yields better clinical outcomes than malreduction arthrodesis. The TMT1dp, representing midfoot abduction, is a key factor for midfoot arthrodesis failure. The extruded medial navicular bone may not affect postoperative medial midfoot pain.

LEVEL OF EVIDENCE

Level III, retrospective comparative study.
