[Recurrent hallux valgus treated with metatarsophalangeal arthrodesis. A series of 32 patients].
OBJECTIVE
We reviewed a series of 32 cases of recurrent hallux valgus treated by great toe metatarsophalangeal arthrodesis with a minimal 5-year follow-up.


METHODS
Mean delay from the first surgical procedure and revision surgery was 11 years. All patients complained of forefoot pain. The average angle of the phalangeal valgus was 39 degrees. Sixteen patients had metatarsalgia. The first toe metatarsophalangeal joint was evaluated according to Regnauld's classification: two grade 1, eight grade 2a, six grade 2b, sixteen grade 3. Arthrodesis was fixed with an axial screw and associated with adductor hallux plasty. Outcome was assessed at a minimum 5-year follow-up according to Kitaoka's criteria.


RESULTS
Seventy-eight percent of the patients were pain free at last follow-up. Valgus deviation of the great toe was corrected with an average angle of 19 degrees. The arthodesis healed in 90.6% of the cases. Statistical analysis showed the importance of great toe valgus pre- and postoperatively and at last assessment. Final outcome was poor in the oldest patients. The overall outcome was rated good in 84% of the cases, average in 6% and poor in 10%.


CONCLUSIONS
Arthrodesis of the great toe is not a disabling surgery. Interphalangeal osteoarthritis may occur due to joint overuse (12 cases). Kitaoka's series compared outcome after arthrodesis with that after conservative surgery and reported better results with arthrodesis. Revision surgery for hallux valgus using great toe metatarsophalangeal arthrodesis remains an acceptable alternative.
