Modified Lapidus arthrodesis with plantar plate and compression screw for treatment of hallux valgus with hypermobility of the first ray: A preliminary report

BackgroundTMT-1 arthrodesis is an established method in hallux valgus surgery, but it is technically demanding and typically calls for a period of postoperative immobilization.MethodsIn this cohort study, initial experience with a plantar plate is described. 58 patients (59 arthrodesis) were included.ResultsThe mean duration of protected full weight bearing was 7 weeks. 94.12% patients were satisfied with the results, bony union was achieved in 98.31%. The Foot Function Index improved by 33 to a mean of 8 (p < .001). The postoperative Mayo Clinic Forefoot Score was excellent in 47.04 and good in 47.04%. The mean hallux valgus angle improved by 24.4–13.2° (p < .001). The mean first intermetatarsal angle improved by 11.2–5.2° (p < .001).ConclusionInitial experience with this form of fixation appears to provide suitable stability, allow early-protected weight bearing, with an acceptable level of complications.
