Background:
The purpose of this study was to determine the results of an arthrodesis technique of the first metatarsophalangeal joint (MTPJ) using a precontoured dorsal plate to correct the hallux valgus deformity.
Methods:
This was a retrospective analysis of outcomes for first MTPJ arthrodesis performed using 2 precontoured dorsal plates. Radiographic outcomes (intermetatarsal angle [IMA] and hallux valgus angle [HVA]) and patient-reported functional outcome measures (Short-Form 12 and Foot and Ankle Outcome Score) were recorded and compared.
Results:
Fifty-five patients underwent 77 first MTPJ arthrodeses for severe hallux valgus deformity with associated degenerative changes at the first MTPJ. The mean reduction of the IMA was 5.67° (P < .05) and the mean reduction of the HVA was 33° (P < .05). The Short-Form 12 assessment of global health demonstrated a significant improvement in both the physical and mental health composite scores by 16.4 points and 10.4 points (P < .05), respectively. The Foot and Ankle Outcome Score demonstrated a cumulative decrease of 35% (59.28; P < .05) in all domains.
Conclusions:
First MTPJ arthrodesis using a precontoured dorsal plate is a successful procedure with a high union rate, low complication rate, and a high level of patient-reported satisfaction.
Levels Of Evidence:
Level III.
