P.886 Difficulties in delivery and depressive symptomatology in schizophrenia

Abstract

Cartiva synthetic cartilage implants (SCI) have been designed for treatment of conditions affecting the second metatarsal head. Osteotomies are regularly performed for the treatment of conditions affecting the second metatarsal head such as Freiburg’s disease. A comparative study between these two procedures has not yet been performed.Patients at a single centre with symptomatic conditions affecting the second metatarsal head who received Cartiva SCI or a primary Osteotomy were identified, and patient-reported outcomes were evaluated using MOXFQ and the FAAM questionnaires.Six Cartiva SCI and 7 Osteotomy patients were identified and included in this study. All patients were female and were followed up for an average of 19 months (SD +/- 5.6) and 27 months (SD +/- 10.9) respectively.Cartiva SCI MOXFQ Index scores improved by 13 points from 57 to 44 (33%). Walking/and Pain domain scores improved, however, Social interaction deteriorated. Mean FAAM scores improved by 10% from 65% to 75%, and subjective FAAM scores improved by 7% from 48% to 55%. Four of the six Cartiva patients (3 Freiberg’s disease and 1 Osteochondral defect) had revisions to Weil osteotomies at a mean of 15 months post-operatively.The Osteotomy group had improved MOXFQ Index and 3 Domain scores. FAAM scores improved by 26% from 66% to 92% and subjective FAAM scores improved by 28% from 60% to 88%.Second metatarsal head osteotomies result in high functional outcomes and should be the mainstay of treatment, especially when there is avascular necrosis of the metatarsal head.
