Review of 107 hallux MTP joint arthrodesis using dome-shaped reamers and a stainless-steel dorsal plate.
BACKGROUND
The purpose of this study was to retrospectively review the results of patients treated with hallux MTP joint arthrodesis using dome-shaped reamers for joint preparation and a precontoured dorsal stainless steel plate for internal fixation.


METHODS
A series of 145 patients (155 feet) were identified. Postoperative evaluation included weightbearing radiographs, physical examination, and chart review. Outcomes were assessed with a pain visual analog scale, AOFAS hallux score, as well as a detailed questionnaire and a subjective satisfaction survey.


RESULTS
Ninety-eight patients (107 feet) met the criteria for the study. The mean followup was 61 weeks. Revision cases accounted for 18.7% (20/107). Rheumatoid arthritis (RA) was present in 32.7% (35/107). The average postoperative AOFAS hallux score was 79.7 and pain VAS was 19. The average pre- and postoperative hallux valgus angle was 26.5 and 12.3 degrees, respectively (p < 0.05). Eighty-nine of 107 patients (83.1%) reported good to excellent results at final followup. Discomfort related to prominence of the plate occurred in 14.9% (16/107). The nonunion rate was 12.1% (13/107). The nonunion rate for patients with/without RA was 22.9% (8/35) and 6.9% (5/72), respectively (p < 0.05). Patients with a nonunion noted more hardware related pain than those with a union (p < 0.05).


CONCLUSIONS
First MTP joint arthrodesis using this technique achieves a high union rate. RA patients have a lower union and higher complication rate.
