Advances in Posteromedial Translation for Multiplanar Scoliosis Correction: Technique, Outcomes, and Future...

Posteromedial translation (PMT) is a widely utilized corrective technique in scoliosis surgery, offering a versatile approach to 3D deformity correction. Since its initial description, this technique has undergone significant evolution, incorporating various instrumentation systems such as sublaminar wires, polyester bands, hooks, claws, and pedicle screws. Posteromedial translation enables effective coronal correction, restoration of thoracic kyphosis, improvement of cervical lordosis, and rotational realignment, while minimizing stress on individual fixation points. Nevertheless, limitations remain, including neurological risks with sublaminar devices, implant-related complications, and varying efficacy in rotational correction. This comprehensive review examines the historical development, biomechanical principles, indications, instrumentation advancements, clinical outcomes, complications, and future perspectives of PMT in scoliosis surgery.
