Radiological Outcome of Patients with Splay Foot Following 1st and 5th Metatarsal Osteotomies Performed Simultaneously on the Same Foot

Introduction: There have been many operations documented for the treatment of hallux valgus and 5th metatarsal bunionette deformities in splay foot patients done separately with variable success rates. Our aim was to radiologically assess outcome following both chevrons osteotomy to the 1st and reverse chevrons osteotomy to the 5th metatarsals in symptomatic patients with splay foot. To our knowledge, this procedure has not been described in the literature. Materials and Methods: 9 symptomatic patients (12 feet) were included in the study. The pre-operative and post-operative angles were assessed on weight bearing X-rays for statistical significance using non-parametric paired T tests. Results: Hallux valgus angles, intermetatarsal angles, 1st and 5th metatarsal head widths, and maximum distance between 1st and 5th metatarsals head all have significantly decreased post-operatively (p< 0.05). Conclusion: The results suggest a very good radiological outcome in symptomatic patients following simultaneous 1st and 5th metatarsal osteotomies. All the angles measured except for the DMAA showed a statistically significant reduction postoperatively.
