The long-term outcome of juvenile hallux valgus treated by a modified Austin procedure was investigated. The clinical (subjective, AOFA Scores) and radiological outcome (hallux valgus angles, intermetatarsal angles, position of the sesamoid bones and metatarsal index of 15 feet in 12 patients, aged 14 years and 2 months (SD +/- 1 year 10 months) were assessed pre- and postoperatively and after 7 years and 3 months (SD +/- 3 years). A significant improvement of the hallux valgus angle and of the intermetatarsal angle was obtained, persisting until final follow-up. The mean American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal and AOFA-Midfoot score were 94.5 points and 853 points, respectively. The modified Austin procedure appears to be an effective procedure to correct a juvenile hallux valgus deformity, with long lasting improvement, no growth disturbances and good functional outcome.
[Show abstract][Hide abstract] ABSTRACT: The management of adolescent hallux valgus (AHV) remains controversial, with reservations about both conservative and surgical treatments. Non-operative management has a limited role in preventing progression. Surgical correction of AHV has, amongst other concerns, been associated with a high prevalence of recurrence of deformity after surgery. We conducted a systematic review to assess clinical and radiological outcomes following surgery for AHV.
A comprehensive literature search was performed in the Cochrane Library, CINAHL, EMBASE, Google Scholar and PubMed. The study was performed in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Demographic data, radiographic parameters and results of validated clinical scoring systems were analysed.
The published literature on AHV is largely heterogeneous and retrospective. Nine contemporary studies reporting on 140 patients (201 osteotomies) were included. The female to male ratio was 10:1. The mean age at operation was 14.5 years (range 10.5-22). The mean follow-up was 41.6 months (range 12-134). The mean post-operative American Orthopaedic Foot and Ankle Society (AOFAS) score was 85.8 (standard deviation, SD ±7.38). The mean AOFAS patient satisfaction showed that 86 % (SD ±11.27) of patients were satisfied or very satisfied with their outcome. On the duPont Bunion Rating Score (BRS), 90 % rated their outcome as good or excellent. There was a statistically significant improvement in the inter-metatarsal angle (IMA, p = 0.0003), hallux valgus angle (HVA, p < 0.0001) and distal metatarsal articular angle (DMAA, p = 0.019).
Based on the most current published evidence, contemporary surgical interventions for AHV show excellent clinical and radiological outcomes, with high patient satisfaction. The rates of recurrence and other complications are lower than the historically reported figures. There is a need for high-level, multi-centre collaborative studies with prospective data to establish the long-term outcomes and optimal surgical procedure(s).
