Abstract
AIMS: This study was aimed to study the arthrodesis of the first metatarsophalangeal joint using an oblique interfragmentary lag screw and dorsal plate as an effective option for the treatment of hallux rigidus. Few researchers have studied the outcome of this surgical method over a long follow-up period. PATIENTS AND METHODS: We performed a retrospective review of 60 patients status post arthrodesis of the first metatarsophalangeal joint. The mean age was 68.5 years and average follow-up lasted for 47.3 months. Patients' satisfaction and functional outcomes were evaluated with the American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale, the foot and ankle questionnaire, the Functional Foot Index, and dynamic pedobarography. RESULTS: Fusion rate of 93.3 % was recorded; 6.7 % of the cases ended up with a painless pseudarthrosis and required no additional surgery. Pedobarographic measurements demonstrated first ray weight bearing function restoration. More physiological foot plantar pressure patterns were observed. Concerning the postoperative outcomes, 71.7 % of the patients were very satisfied and 18.3 % were satisfied. The American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale increased post-operatively from 40.9 to 79.3. CONCLUSION: The arthrodesis of the metatarsophalangeal joint using transarticular screw and dorsal nonlocked plate is an effective method for the treatment of severe hallux rigidus with fair patient satisfaction rate and functional outcome.
