The study's findings also highlight the importance of careful patient selection and meticulous surgical technique to achieve optimal outcomes.

Medical Background

Congenital fibular hemimelia is a rare condition characterized by the absence or underdevelopment of the fibula. This can lead to various deformities, including ankle malalignment, equinovalgus foot deformity, and tibial curvature. The SUPERankle procedure is designed to address these deformities by correcting the ankle alignment and providing a stable platform for further surgical interventions, such as external fixator application or intramedullary nail insertion.

How the Procedure Works

The SUPERankle procedure involves a combination of osteotomies and distraction osteogenesis to correct the ankle malalignment and deformities. The procedure is typically performed in a staged manner, with the initial surgery focusing on correcting the ankle alignment and subsequent surgeries addressing any remaining deformities or length discrepancies.

Who Is a Candidate?

Candidates for the SUPERankle procedure are typically children with severe FH, characterized by significant ankle malalignment and deformities. The ideal candidate should have a sufficient amount of bone stock to allow for stable fixation and bone regeneration. Patients with more mild forms of FH may not require such an extensive procedure, and their treatment can be tailored to address their specific needs.
