[Talonavicular arthrodesis for the rheumatoid foot].

BACKGROUND

Talonavicular joint fusion has been successfully applied for the surgical treatment of the rheumatoid foot. Several fixation techniques have been suggested for this purpose, however, with high rates of non-union.

METHODS

Based on seven cases operated in our division, talonavicular joint fusion with two 3.5 mm compression screws and autologous bone grafting is discussed. Pain in the operated foot under weight-bearing conditions was assessed before surgery and after a mean follow-up of 35 months (range 3-58 months).

RESULTS

Solid talonavicular fusion was achieved clinically and radiologically in all patients after 12 weeks. The surgery-related morbidity was low. At follow-up, weight-bearing pain was diminished compared to the preoperative status.

CONCLUSIONS

Compression screw arthrodesis of the talonavicular joint in combination with autologous bone grafting is highly successful in rheumatoid arthritis patients.
