PURPOSE: To review the outcome of arthrodesis of the hallux metatarsophalangeal (MTP) joint in 23 patients.
METHODS: Records of 9 men and 14 women aged 27 to 88 (mean, 57) years who underwent arthrodesis of the hallux MTP joint using an intramedullary device and an intra-osseous device were reviewed. Indications for surgery were severe hallux valgus (n=15), hallux rigidus (n=6) and rheumatoid arthritis (n=2). Outcome measures included visual analogue score (VAS) for pain, the American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, bone union, hallux valgus angle (HVA), dorsiflexion angle (DA), complications, revision, and patient satisfaction.
RESULTS: The mean follow-up was 19 (range, 6-38) months. The mean AOFAS score improved from 29 to 75.4 (p<0.0001) and the mean VAS for pain improved from 8.1 to 2.4 (p<0.0001). 20 (86%) of the patients were satisfied with the outcome. The mean HVA was 14º and the mean DA was 22º. 19 (83%) of the toes had a well-aligned hallux. 21 (91%) of the patients achieved arthrodesis of the hallux MTP joint. The remaining 2 patients underwent revision surgery for failed fusion or infected non-union; they continued to have transfer metatarsalgia despite bone union.
CONCLUSION: The intramedullary and intra-osseous devices for arthrodesis of the hallux MTP joint achieved good outcome in terms of AOFAS score, VAS for pain, HVA, DA, bone union, and patient satisfaction.
