Personalized Surgical Approach for Nonunion of the Second Metatarsal Fracture and Post-Traumatic Metatarsalgia: A Case Report and Literature Review.

Nonunion of the second metatarsal presents a significant clinical challenge, often leading to pain, functional impairment, and deformity. Various treatment strategies have been described in the literature, tailored to the patient's specific characteristics. To provide a comprehensive overview of the available therapeutic options, a literature review was conducted. In this context, this article aims to present an innovative and personalized surgical technique for patients with nonunion and an altered metatarsal formula following a proximal shaft fracture of the second metatarsal. This technique enables the simultaneous consolidation of the nonunion and restoration of metatarsal alignment, with favorable clinical, functional, and radiological outcomes observed over a three-year follow-up period.
